2 Master-Bilt initiated our Energy Saver program to help you quickly identify features that serve your efficiency needs. Below is a list of features and options included in the program. See for future updates. Product/Feature Energy-Saving Function Where Used Demand defrost Initiates electric defrost heaters only as needed As part of the optional Master Controller Reverse Cycle Defrost electronic control system on walk-ins Electric expansion valve Reverse cycle defrost LED lighting MBWA-1 digital alarm/light management system Glass Sentry II EC motors on fans Highly efficient valve eliminates need to maintain a high head pressure (head pressure control valve eliminated also) allowing a lower head pressure and condensing temperature. A compressor operating at a lower condensing temperature yields higher capacity with less energy input. A reverse cycle valve reverses the flow of high temperature refrigerant through evaporator coil, heating along its entire length and eliminating frost buildup. Results in up to an 80% decrease in defrost energy usage as well as a major reduction in defrost time. LEDs use less electricity than fluorescent lights with electromagnetic ballasts and introduce less heat into the refrigerated space which reduces the workload on the refrigeration system s compressor. The less the compressor operates, the more energy is saved. LEDs also last up to 50,000 hours. Door open alarm prevents door from being left open. Optional light management system automatically turns off lights after a programmed interval. The Glass Sentry II anti-sweat control module is designed to save energy by turning off glass door and frame heaters when no door heat is necessary. Amount of torque and current required to start ECMs is low, making them more efficient. ECMs run cooler, reducing heat load to refrigerated space which makes the compressor run less. 4" thick walk-in panels Standard 4-inch panel with R-32 rating meets federal EISA requirements for freezers and surpasses R-25 requirements for coolers. 5" and 6" thick walk-in panels Thickness of panels produces a higher R-factor and energy efficiency which surpasses federal EISA requirements. Low energy or energy free standard walk-in entry doors Scroll compressors MRS & DRS series multi-compressor remote refrigeration systems PS series multi-compressor parallel refrigeration systems V-series doors have a PVC thermal break between the door and frame which minimizes heat transfer between the refrigerated space and the outside. Cooler doors don't require anti-sweat heat and freezer doors only require a low wattage heater in the frame. Up to 20% increase in efficiency vs. reciprocating compressors. Scrolls are also 50% more reliable than reciprocating types. Since these systems are remote, the heat produced by multiple condensing units is removed from the kitchen or sales space reducing the air conditioning load and energy bill Parallel units can match refrigeration capacity to actual load for a 20%+ savings over a single compressor unit.

3 GENERAL PRODUCT INFORMATION EXPERIENCE Master-Bilt has been a manufacturer of quality refrigeration equipment of all types for over 75 years and a pioneer in the use of foam insulation since the early 1950s. Master-Bilt has designed and built countless refrigerated buildings and cabinets using time-proven urethane foamed-inplace construction. A complete sales and engineering staff is available to work with you in designing the appropriate, technically correct refrigerated structure for your needs. FOAMED-IN-PLACE PANEL CONSTRUCTION Master-Bilt pour-type, foamed-in-place panels are offered in standard 4" thickness with optional 5" and 6" thicknesses. They are formed of rigid urethane insulation having a 97% closed cell content to prevent moisture absorption. All panels are interchangeable, precision-formed and feature bulb-type, NSF-listed gaskets. These gaskets are foamed-in-place on the interior and exterior edge of each panel to additionally assure a sound, airtight seam at all joints of adjoining panels.

9 WALK-IN SELECTION CEILING AND WALL CLEARANCES Please keep the following points in mind when determining space requirements for your walk-in. When a ceiling mounted refrigeration system is used, the distance between the top of the walkin and the building ceiling should be at least the height of the condensing unit or housing plus an additional two inches (additional five inches for PRS-2 systems) to allow proper air circulation. For easier maintenance and service access, allow two feet from the top of the refrigeration system housing to the building ceiling. A minimum space of two inches must be allowed between the ceiling of the walk-in and the building ceiling to permit installation of the walk-in ceiling. A minimum of two inches should be allowed between walk-in walls and building walls. The extra space compensates for irregularities in building construction and provides an air space which increases the walk-in's operation efficiency. 3 3 All specifications subject to change without notice. 6-17

Roofs for outdoor warehouses have three support options: Beam and bar joist construction, beam and plate suspension and bar joist and column construction. All these options are designed to your exact requirements. For more details on roofs, see the drawings in this section and in Section 12, part 9O. REFRIGERATION Master-Bilt offers remote refrigeration systems ranging from 1 /2 H.P. to 40 H.P. These systems are either air or water cooled and come in temperature ranges from +70 to -20 F. Multi-compressor, packaged and parallel systems are also available. DOOR CONSTRUCTION Master-Bilt s infitting doors are lightweight and made with urethane foamed-in-place insulation. Each door is fitted with two cam-lift hinges, spring loaded hinges and heavy-duty door closers for effortless opening and closing. An airtight seal is assured by the wide surface magnetic gasket around the door. In addition, doors feature field adjustable hinges to compensate for any necessary future door adjustment without removal of the door or its frame. This refrigeration line-up contains eleven 30 H.P. and two 25 H.P. condensing units. It is typical of Master-Bilt s ability to design a system to match any warehouse requirement. 4 1 All specifications subject to change without notice. 6-17

42 FLOORS AND CEILINGS FLOORS Master-Bilt has a tested design for every floor need, in both indoor and outdoor applications. Any existing designs can be modified by our engineering department to meet your most exacting requirements. The standard Master-Bilt floor is NSF-7 listed with a.080 textured aluminum surface. This tough floor is also safer. Its raised textured pattern provides workers with better traction, thereby reducing the potential of slip and fall accidents (even in wet conditions). Master-Bilt also offers interior and exterior ramps for safe and easy transfer of carts from building floor to cooler/freezer floor. Rugged design of these ramps matches or exceeds the load Typical floor with textured aluminum surface. bearing capacity of walk-in floors. A non-skid safety strip is a standard part of every ramp. PROTECTIVE OUTDOOR ROOFS Three roof packages are available for walk-ins: aluminum prefabricated, membrane and sloped (galvalume). The aluminum prefabricated roof is available in widths up to 24 ft. by length desired (some size limitations do apply). This durable option provides a waterproof covering for the ceiling panels and is designed for rapid, accurate field assembly. The membrane roof is designed for the exact walk-in roof surface desired (a maximum of 2400 actual square feet surface area) with no welding of seams required for installation. Some size limitations do apply. The sloped, or galvalume, roof is available for ft. widths by length desired (some size limitations do apply). These roofs are constructed of a minimum 26 gauge galvalume. The package comes with all necessary fasteners, graduate spacer purlins, galvalume decking, end closures, ridge caps and ridge vents for fast assembly.

63 Master Controller Option The Master Controller Reverse Cycle Defrost (MCRCD) system is an electronic controller for Master-Bilt walk-in cooler and freezer refrigeration systems. It is designed to increase food safety while reducing energy and installation costs. Save 2-4% more energy with the fan cycle option which saves electricity by cycling the evaporator fans during the compressor s off cycle. INSTALLATION SAVINGS No wiring is required between evaporator coils and condensing units (two pairs of low voltage wires, typically thermostat cables, are required to operate the Reverse Cycle Defrost valve and the compressor relay at the condensing unit) In some cases, the savings on wiring installation alone covers the cost of the MCRCD. CONNECTIVITY The Master Controller Reverse Cycle Defrost interface is mounted to an evaporator coil. FOOD SAFETY The reverse cycle defrost function helps prevent food spoilage because it completely and rapidly removes ice build-up in evaporator coils. Ice build-up causes coils to lose the ability to transfer heat properly. Walk-in temperatures then rise, resulting in spoilage. Should there be an issue with the refrigeration system, operators will know instantly through error codes and data provided through online Web2Walk-In software. Web2Walk-In software loaded on each controller allows remote monitoring and programming using any device with a wireless internet or cabled (cat 5) connection. No need for a service tech to climb onto a roof or enter the walk-in to monitor or adjust the refrigeration system. Constant access to data allows users to improve refrigeration system performance and avoid service issues. ENERGY SAVINGS Patented design saves up to 27% more energy than an all-mechanical system Reverse cycle technology reduces defrost energy usage by up to 80% over traditional electric heaters. Demand Defrost technology initiates reverse cycle defrosts only as needed, allowing further energy savings. Master-Bilt 's Web2Walk-In software gives users constant access to refrigeration system performance data. Web2Walk-In can be accessed from any device with an internet connection, including PC, Mac, smartphone or tablet.

78 MASTER CONTROLLER REVERSE CYCLE DEFROST SYSTEM

However, when evaporator coils are blocked due to ice build-up, they lose the ability to transfer heat properly. Temperatures in a refrigerated space can then rise, resulting in spoilage.

79 COLD CONTROLLED Interested in a system that prevents product loss and saves significantly on your energy bill? Maintaining proper, consistent temperature in a walk-in is vital for protecting perishable items. However, when evaporator coils are blocked due to ice build-up, they lose the ability to transfer heat properly. Temperatures in a refrigerated space can then rise, resulting in spoilage. The Master Controller Reverse Cycle Defrost (MCRCD) system is an electronic controller for Master-Bilt walk-in cooler and freezer refrigeration systems. It completely removes frost build-up in coils and works much faster than electric defrost heaters. Its patented design also saves up to 27% more energy than an all-mechanical system. MCRCD is part of a Master-Bilt refrigeration system that also includes a remote condensing unit and one or more evaporator coils. A reverse cycle valve is mounted to a condensing unit as well. Other components are listed on page 6. The MCRCD system is highly efficient since it regulates an electric expansion valve in response to evaporator superheat and return air temperature. MCRCD systems use a floating head control which greatly reduces energy usage in cold ambient areas. Standard Demand Defrost technology initiates reverse cycle defrosts only as needed, allowing further energy savings. In addition to energy savings, the MCRCD system is designed to reduce installation labor and material costs: All electrical components are factory pre-wired and tested No line voltage is required between evaporator coils and condensing units (two pairs of low voltage wires, typically thermostat cables, are required to operate the Reverse Cycle Defrost valve and the compressor relay at the condensing unit) The walk-in doesn t have to be at operating temperature to confirm or set superheat (pre-programmed) No need to install a thermostat and solenoid or set a defrost schedule In some cases, the savings on wiring installation alone covers the cost of the MCRCD. WEB2WALK-IN: COMPLETE CONTROL AT YOUR FINGERTIPS... FROM ANYWHERE. Because each Master Controller is accessible through any web browser, you have complete 24/7 control from anywhere on the globe. The Web2Walk-In software loaded on each controller allows you to remotely monitor and program all data and setpoints using any device with a wireless internet or cabled (cat 5) connection*. With Web2Walk-In, there s no need for a service tech to climb onto a roof or enter the walk-in to monitor or adjust the refrigeration system.

80 DEMAND DEFROST Eliminate unnecessary defrosts and wasted electricity. Eliminate unnecessary defrosts with Master-Bilt s revolutionary Demand Defrost technology featured in the MCRCD system. Demand defrost offers a more efficient alternative to mechanical defrost timers. With most mechanically-based low temp refrigeration systems, electric heaters installed on evaporator coils are used to melt accumulated frost. The heaters are pre-set to engage at certain times of the day regardless of the amount of frost build-up on the coil. Frost accumulation, however, is not always consistent. It is influenced by changeable conditions like ambient temperature, humidity and product load. If a defrost is initiated before a significant amount of frost accumulates, energy is wasted. Conversely, demand defrost constantly checks for the buildup of ice on an evaporator coil to determine if defrosting is required. If a defrost is needed, the standard Reverse Cycle Defrost method is initiated. For more on Reverse Cycle Defrost, see page 4. Our extensive laboratory tests indicate Demand Defrost eliminates many unnecessary defrosts and reduces energy consumption.

82 ENERGY SAVINGS POTENTIAL Master Controller Reverse Cycle Defrost provides up to 27% energy savings over an all-mechanical refrigeration system. Reverse cycle defrost can help gain LEED points since it meets the U.S. Green Building Council s LEED prescriptive of no electric defrosting as outlined in LEED 2009 for Retail: New Construction and Major Renovations. (Online at SAVE EVEN MORE ENERGY WITH FAN CYCLING OPTION Save 2-4% more energy by choosing the fan cycle option for the Master Controller. This option saves electricity by cycling the evaporator fans during the compressor s off cycle. When the compressor is off, fan energy consumption is up to 60% less than if the fans were constantly running. In addition to the actual energy savings, cycling fan motors 5 expel 60% less heat into the walk-in which lowers the compressor s run time. A proprietary fan control algorithm protects stored products by keeping fans running sufficiently to maintain the desired temperature in the walk-in. Overall system energy savings vary depending on factors such as the size of the system, design temperature and run time, location of the walk-in and type of defrost used.

98 OPTIONS AND ACCESSORIES For more details on options and accessories, see Section 12, part 9 MASTER CONTROLLER REVERSE CYCLE DEFROST SYSTEM (See Section 12, part 12E for specifications) COLD CONTROLLED The Master Controller Reverse Cycle Defrost (MCRCD) system is an electronic controller for Master-Bilt walk-in cooler and freezer refrigeration systems. Its patented design saves up to 27% more energy than an all-mechanical system. The MCRCD system is highly efficient since it regulates an electric expansion valve in response to evaporator superheat and return air temperature. Additionally, integrated Reverse Cycle Defrost (see p. The MCRCD system interface is mounted to an evaporator coil. 9.12) completely removes frost build-up in coils and works much faster than electric defrost heaters. Standard Demand Defrost technology initiates reverse cycle defrosts only as needed, allowing further energy savings. In addition to energy savings, the MCRCD system is designed to reduce installation labor and material costs: All electrical components are factory pre-wired and tested No line voltage is required between evaporator coils and condensing units (two pairs of low voltage wires, typically thermostat cables, are required to operate the Reverse Cycle Defrost valve and the compressor relay at the condensing unit) The walk-in doesn t have to be at operating temperature to confirm or set superheat (preprogrammed) No need to install a thermostat and solenoid or set a defrost schedule 9 11 In some cases, the savings on wiring installation alone covers the cost of the MCRCD. DEMAND DEFROST Demand defrost is a more efficient alternative to mechanical defrost timers. With most mechanicallybased low temp refrigeration systems, electric heaters installed on evaporator coils are used to melt accumulated frost. The heaters are pre-set to engage at certain times of the day regardless of the amount of frost build-up on the coil. Conversely, demand defrost constantly checks for the buildup of ice on an evaporator coil to determine if defrosting is required. If a defrost is needed, the standard Reverse Cycle Defrost method is initiated.

100 OPTIONS AND ACCESSORIES For more details on options and accessories, see Section 12, part 9 REVERSE CYCLE DEFROST Increase defrost efficiency with Master-Bilt s built-in patented* Reverse Cycle Defrost method. When the Master Controller s Demand Defrost determines a defrost is necessary, a reverse cycle valve installed on the refrigeration system s condensing unit is activated and high temperature refrigerant flow is reversed. The refrigerant flows back through the evaporator coil heating it along its entire length, completely eliminating frost build-up. In comparison, only a certain amount of the coil is heated by electric defrost heaters, leaving ice deposits which weaken the evaporator s performance. Reverse cycle technology offers several significant advantages. First of all, the process uses less energy than electric defrost heaters. Reverse cycle reduces defrost energy usage by up to 80%. This savings plus that gained from the demand defrost feature and elimination of head pressure control valves dramat-ically reduces electrical bills. Reverse cycle eliminates not only the need for defrost heaters and head pressure control valves, but also check valves and expansion valves at the condenser. With reverse cycle, liquid receivers are also unneeded on most condensing units. Removing these components decreases the cost of the evaporator itself and saves on installation and wiring. Defrost time is also greatly shortened. The average defrost time for a freezer with electric heaters is 20 to 30 minutes. Reverse cycle can perform a completely clean defrost in as little as 3 to 5 minutes in a freezer or 1 1 /2 to 2 minutes in a cooler. Because the defrost is so rapid, there s no noticeable increase in freezer temperature and product temperature rise is also significantly less. *U.S. patent no. 7,073, All specifications subject to change without notice. 6-17

OPTIONAL MASTER CONTROLLER REVERSE CYCLE DEFROST SYSTEM The refrigeration system of a walk-in cooler or freezer may be equipped with a Master Controller Reverse Cycle Defrost (MCRCD) electronic control system (U.S. patent no. 7,073,344) mounted to the refrigeration system. The MCRCD system is custom-designed for Master-Bilt walk-in coolers and freezers to control an electric expansion valve in response to evaporator superheat and return air temperature. The Master Controller is part of a Master-Bilt refrigeration system which includes either a remote condensing unit (B-series or M-series) or a multi-compressor system (MRS, DRS or PS series) and one or more evaporator coils. A reverse cycle valve is also mounted to the condensing unit. Remote communication with the Master Controller system will be provided through internetbased software. Through this interface, users will be able to remotely monitor and program all data and setpoints either through wireless internet or cabled (cat 5) connection. No line voltage connections will be required between evaporator coils and condensing units. Two circuits of low voltage wiring will be required from terminals in the evaporator coil to terminals in the electrical panel or enclosure at the condensing unit or rack. Standard five wire thermostat cable is a permissible product for this provision. Voltage for the evaporator may be pulled from the condenser when evaporator is 220/60/1. Additionally, a refrigeration system containing a Master Controller will consist of the following factory-mounted parts: All specifications subject to change without notice

119 SPECIFICATIONS Digital control board mounted to evaporator coil Electric expansion valve Reverse cycle valve 24VAC transformer Three solid state temperature sensors External relay to control the liquid line solenoid valve or compressor contactor Pressure transducer The Master Controller board will contain four output relays: defrost heater (20A), evaporator fan (10A), alarm (3A) and liquid line solenoid (compressor) (3A). It will be possible to configure this Master Controller system in a peer-to-peer application for up to a total of 6 evaporator controllers. Reverse cycle defrost will be the default method for MCRCD systems on walk-in coolers and freezers. Reverse cycle defrost will be accomplished by means of a reversing valve installed on the refrigeration system's condensing unit. This valve will reverse the direction of high temperature refrigerant through the length of the evaporator coil to remove ice buildup. The MCRCD system will also be equipped with demand defrost technology which will constantly monitor an evaporator coil for ice buildup before initiating a reverse cycle defrost. The room temperature range will be -40 F to 75 F. Medium temperature application is pre-set at 35 F cut-out room temperature with scheduled defrost. Low temperature application is pre-set at -10 F cut-out room temperature with demand defrost. The cut-in temperature differential is 5 F by default. These set points can be field set at the job site if different settings are desired. 12E. OPTIONAL SUPER CONTROLLER SYSTEM When specified, a walk-in cooler or freezer refrigeration system may be equipped with a Super Controller system similiar to the Master Controller Reverse Cycle (MCRCD) system but with the sole function of controlling an electronic expansion valve. The Super Controller may be considered when the complete functionality of the MCRCD is not required. The factory-mounted system consists of a superheat control board (mounted to evaporator coil), electric expansion valve, pressure transducer, solid state temperature sensor, 24 VAC transformer, terminal board, terminal block and mounting spacer. With new installations or when retrofitting an existing refrigeration system, the head master (head pressure control valve) is no longer necessary and is eliminated allowing additional energy savings. As with the MCRCD system, the control algorithm permits the compressor head pressure to be free floated within its operating range with variable ambient temperature. Therefore, the refrigeration system in low ambient condition can achieve the highest possible Energy Efficiency Ratio. 12F.
