Function Air removed by exhaust systems must be replaced systematically by outside air. If this is not done, the exhaust system, while in operation, creates a negative pressure inside the building. The negative pressure conditions created reduce the overall effectiveness of the exhaust and ventilating systems of the entire plant. Smoke, fumes or corrosive vapors from manufacturing processes will build up, making personnel uncomfortable and reducing their efficiency. In the winter months, make-up air provides a dual function of supplying tempered outside air for heating as well as air to balance the system. If a negative pressure exists, hot and cold spots are likely to develop since airflow is not uniform throughout the building. Workers near windows and other openings are subject to cold drafts. The infiltration of cold air overloads the existing heating system in the winter, thus reducing its efficiency. The installation of a heated make-up air system will eliminate these negative pressure problems in the plant. Both the central heating system and the exhaust or ventilating system will be restored to full operating efficiency. Advantages of make-up air in your plant: 1. Worker comfort and efficiency increase because dust, fumes and contaminants can be removed efficiently by the existing exhaust systems. 2. Bothersome drafts and cold spots are eliminated. 3. Stacks on ovens, boilers and other direct or indirect fired equipment are restored to full efficiency. 4. Overloaded plant heating systems are returned to normal operation. 5. Water condensation problems are reduced or eliminated. 6. Low initial equipment cost (assuming boiler capacity is already available) on steam units. 7. No elaborate safety controls resulting in few nuisance shutdowns. 8. Simple control system and therefore electrical maintenance is simplified. 9. Minimal safety hazards. A Single Package Assembly Gas The Hartzell gas fired units produce very low levels of CO and are easy to maintain. Base unit consists of fan and burner sections. Many optonal features are available. Steam The Hartzell steam make-up air unit is a single package assembly. The standard unit includes fan, housing, steam coil, and shutter, pre-wired except for the steam valve. (Plumbing and valve wiring are supplied by the customer at the job site.) The standard control package provides for constant discharge air temperature, and low temperature shutdown to protect against coil freeze-up. 4

Return Air Recirculating Unit Controls Manual Operation During down-time recirculating shutters are closed. Upon start-up, Recirc Shutter moves to whatever position the Return Air controller is set, up to 80% recirc air. The Shutter at the Burner moves conversely to the above Recirc Shutter, maintaining proper velocity across the burner. Flame Safeguard monitors normal startup. Closes main gas valve instantly upon flame failure. Automatic gas shut-off valve opens after all safety devices are satisfied and gas pilot is ignited and proved by flame safeguard. Automatic Operation Automatic modulation for face- and Recirc Dampers. Dampers are modulated based on internal building pressure. Set point can be adjusted on controller at remote station. If a pressure signal is supplied, a controller reads the signal and compares it to the controller setpoint. Discharge temperature controller maintains constant discharge air temperature. Modulating solenoid opens/closes gas valve as ordered by controller. The controller then provides an output signal to the damper actuators to modulate the return air and burner (outside air) dampers. This maintains proper airflow velocity across the burner. 7

Perimeter curb mount accommodates weather and leakage protection when the unit is mounted on a full perimeter prefabricated roof curb. Prefabricated roof curb full perimeter mount with built-in wooden nailer strip that facilitates fastening the unit to the curb. Includes a rigid 1 1 ¼2 thick 3-lb. density glass fiber liner, which eliminates condensation problems. 1/4 neoprene sealer strip is standard. Construction is galvanized steel with fully welded seams. Optional Recirculation Features (GMC model shown) Air recirculation feature available on both centrifugal (GMC) and propeller (GMP) models, is designed to provide continuous building air make-up, pressurization, and heating with maximum efficiency. These self-contained units are fully factory wired, plumbed, assembled and tested. They are designed to provide control of the make-up air volume, via pressure or manually adjusted potentiometer. Units are direct fired, designed to burn either natural gas or propane with 20% to 100% fresh air intake and 0% to 80% recirculated air. This allows recirculation of clean plant air when heating, pressurization requirements and exhaust loads are at minimum levels. 12

Series 79 Gas Fired Door Heater Heating has always been a problem in plants, warehouses, factories, etc., when overhead doors are frequently opened and closed. The rushing in of cold air when the doors are open chills personnel and lowers their working efficiency. Normal heating systems, such as unit heaters or duct systems, are not capable of handling this problem. Furthermore, an extra, sudden load is thrown on the heating system and as a result, heating costs rise substantially. This bothersome and costly problem can be solved by the Hartzell Automatic Door Heater which directs a blast of high velocity heated air toward the door opening. As a result of the turbulence created, the hot air mixes with the cold air, and the bite of the cold air is eliminated. The Hartzell unit works whenever the door is raised far enough to trip the switch. The fan starts, after a brief pre-purge time period, and safety function check, a high velocity stream of heated air is blasted into the cold entering air. Hartzell Automatic Door Heaters come equipped with Duct Axial propellers designed for high velocity at medium noise levels. These heaters can be mounted in either horizontal or vertical position or at any angle in between. Every Hartzell Automatic Door Heater is completely assembled and tested at the factory and is shipped ready for installation. Generally, the only installation requirement is connecting a unit to the electrical and fuel supply systems.

Series SAH and Series SCH Face and Bypass Assembly Series SAH Horizontal Axial Flow (shown) Series SCH Horizontal Centrifugal Face and bypass units provide better temperature modulation in marginal, as well as, extended cold weather by varying the airflow through the coil by means of proportioned face and bypass dampers. The damper enclosure is designed with a plenum chamber containing guide vanes providing for proper mixing of air. The result is modulating temperature control with full steam pressure at all times reducing the problem of coil freeze-up. The face and bypass section is available in two designs utilizing a Hartzell duct axial fan (Series SAH) or a DWDI forward curve centrifugal fan (Series SCH). Both are designed as packaged units with controls mounted and wired. Features: Series SAH Axial Units 8,000 to 45,000 CFM...works up to 1 external static pressure. Utilizes the Hartzell 6-bladed duct axial fan. Vane section available for higher static pressures up to 3 external. Series SCH Centrifugal Units 8,000 to 45,000 CFM...works up to 1 1 2 external static pressure. Utilizes a DWDI heavy-duty industrial forward curve wheel. General Features: 12-gauge steel housing reinforced with self-forming ribs for rigidity and flanges. Welded construction. Horizontal discharge is standard. Can be built for vertical up or down position. Easy coil removal...slide in and out of the unit on rails. Belt drive arrangement, motor out of the airstream. Drive bearings have extended grease tubes for servicing. Belts are oil, heat and static resistant. Belt guards are standard. NEMA 12 remote control station with pilot lights. Controls are mounted in a NEMA 4/12 panel and enclosure containing the motor starter, control transformer, fuses, and terminal strips. Wiring to the fan motor must be done at installation. (Connections to the steam valve and optional room thermostat are made at the time of installation). Modulating temperature control. Temperature sensing element mounted in the airstream. Low temperature limit control mounted within coil housing. Unit can be used in both indoor and outdoor installations. Steam and return lines should be insulated in a common housing to prevent freezing in outdoor installations. Motor operated dampers. Access door for servicing is standard. Filter Box optional. Specify Type A (less filters) or Type B (with filters). Can be located on inlet only. Accessories see Pages 38 and 39. 32

Series 77 Steam Unit Heaters Series 77 Steam Unit (1-Row) Series 77 Steam Unit (2-Row) Hartzell direct drive steam unit heaters are powered to utilize the full high heat transfer efficiency of the unit by efficient translation of power into air movement. The characteristics which make a unit heater so superior to heating devices which depend on radiation are the ability to quickly extract a very high proportion of the heat contained within the primary heating element and to distribute that heat evenly. The key to economy and quality of performance lies in the propeller which forces air through the heater and distributes it evenly and thoroughly into all corners and recesses of the area to be heated. The Hartzell steam unit heater is equipped with either 1-row coils (Series 771) or 2-row coils (Series 772) of the fin and tube type, high efficiency cast aluminum propeller direct connected to a totally enclosed fan duty motor. Two 1/2 13 N.C. tapped holes for support rods provided. See page 3 for performance data. Special coil sections may be provided to meet specific application requirements. The Cores in unit heaters have copper headers and seamless copper tubes with copper brazed joints, and copper fins. Varied fin spacing. Cores are guaranteed up to 150 psig saturated steam and 366 F. Standard mounting of the steam unit heater is in vertical position, capable of being tilted as much as 60 downward. Rugged steel support rods and motor base are standard on Hartzell steam unit heaters. The Ideal Heating Unit Initial Cost Lower per square foot of area to be heated than any other method of heating. Installation Cost May be installed in about a fourth of the time required for radiation. Heat Circulation Distributes heat thoroughly. Eliminates cold spots and cold floors. Space Saving Suspended along a wall, beam or ceiling, the average Hartzell unit heater saves at least 45 square feet of usable floor space. Instant Action Touch a switch when heat is needed (or do nothing at all if thermostatic control is used) and heat is produced instantly... no waiting. Louvers Adjustable louvers can be individually set to deliver heat at the exact point desired. Appearance Fabricated steel cabinet with air dry enamel coating. Tips on Placement of Unit Heaters Place units at the points of greatest heat loss (doorways, windows, etc.) Place heaters so that the air stream wipes the outside walls, and the throw from one heater reaches to the next unit. This sets up a circulatory air movement that produces a blanket of warm air along the cold wall. Arrange units so they do not blow directly on workers. Aim air streams down aisles, toward open spaces on the floor, or along exterior walls. Locate heaters so that air streams are not blocked by columns, machinery, partitions, etc. Position units in a building or exposed to a prevailing wind to direct a large portion of the heated air along the windward side. Accessories: Safety Guard Protective rear safety guard of 14 gauge steel is available as an option. 36
