CeilMate TM Applications These systems are designed for commercial IAQ (Indoor Air Quality) applications where cooling, heating, humidifying, dehumidifying, ventilating and air conditioning solutions are required. CeilMate TM systems are ceiling mounted air conditioners, designed for reliable 24/7 operation. Typical critical applications include: Telecommunication switch-gear rooms Data centers Clean rooms Medical MRI and CAT scan rooms Laboratories Bank and ATM kiosks Office and Conference rooms LAN and data relay facilities CM = CeilMate TM Nominal Cooling Capacity (in thousands of Btu/hr) Product Nomenclature CM - 48 - AHU ( 4 ton air handler shown in above example) AH = Air Handling Unit CW = Chilled Water/Glycol System View Electric Box Smoke Detector (optional) Return Air Opening Flange & Filters Separate Fresh Air Intake Refrigeration Specialties & Valves Hot Gas Bypass Inlet Port (optional) Field Piping Connections Electrode Canister Humidifier Stainless Steel Condensate Mounting Supports Drain Pan (4 total) Oversized blower with adjustable sheave and tensioner Belt Driven Blower Motor Heat/reheat (optional)
Cabinet The CeilMate TM is manufactured from aluminum for light weight, corrosion resistance and asthetics. The cabinet is structurally reinforced throughout to provide a stable and secure platform for the air conditioning components. Standard Features Refrigeration System The CeilMate TM system includes all necessary components for safe and reliable operation. Easily accessible components include: thermal expansion valve, sight glass with moisture indicator, refrigeration service access ports, and refrigerant drier/strainer. Split systems include a refrigerant pump-down solenoid to prevent liquid slugging. Units are evacuated and charged with dry nitrogen. The unit s evaporator section is insulated with high density, 3 lb/ ft 2 thermal and acoustical insulation and sealed with self-extinguishing gasket material. Panels are fastened with captive hardware to simplify internal access. Electrical System The unit has a Class 2, 24VAC control circuit, all necessary contactors, fuses and/or circuit breakers for full operation. 24 VAC field connections and high voltage connections are provided through separate termination blocks in the electric box. Two condensate pan overflow switches interlock the control circuit to shut down unit in case condensate drain is plugged. Evaporator Coil The unit has a large face area coil to increase cooling efficiency and reduce power consumption. The copper tube, aluminum fin coil is mounted in a stainless steel condensate pan; a condensate safety switch guards against condensate overflow. Blower and Blower Motor The CeilMate TM uses a belt driven evaporator blower with adjustable sheaves. The air flow pattern is in a draw-thru configuration for even air distribution across the coil. The large blower runs at a low rpm to minimize air noise and motor horse power consumption. The blower motor assembly is mounted to an adjustable base to provide for easy belt tensioning. Optional Features Electric Heat/Reheat Electric reheat is designed to offset the cooling effect of the dehumidification cycle; electric heat provides resistance heat regardless of the dehumidification cycle. The unit incorporates a factory installed, wired and tested nichrome wire heater. The heater has low voltage thermal safety cutouts, one pilot duty automatic resettable and a second power line fuselink (over-temperature) safety device for each bank of heat. Ultra Violet Sterilization Light The unit incorporates a high intensity UV light to sterilize the air passing through the coil. As airborne mold bacteria are exposed to the UV light they are killed, preventing them from depositing active contaminants on the coil surface, the condensate pan and other internal surfaces. As the air is changed several times in the conditioned room, the contaminants are constantly being reduced in number. Electrode Canister Humidifier Integrated with the CeilStat, the humidifier provides humidification to your facility. An optional electrode canister is available providing state-of-the-art humidity control. The humidifier senses cylinder current draw, automatically flushing and filling the cylinder to control the mineral content of the water and humidity output. The output is field adjustable from 1 to 5 lbs/hr. A Change Cylinder light alerts service personel when the humidifier output requires service. 4 AeroSys, Inc.
Fresh Air Damper The 24VAC fresh air actuator controls the outside fresh air damper system based upon the customer supplied demand for outside air. Hot Gas Bypass System includes all piping and components to hot gas bypass. HGBP is designed to maintain evaporator/ suction pressure while modulating cooling capacity of the unit down to approximately 35% of the total cooling capacity. Hot Gas Reheat The system shall include a hot gas reheat coil with control valve to reheat the discharge (leaving) air from the evaporator coil, thereby offsetting the sensible cooling load from the system. Alarms Smoke Detector The air duct smoke detector is specifically designed for use in air handling systems operating with air velocities up to 3,000 fpm. Activation turns off the CeilMate system and can annunciate an alarm. Firestat The adjustable firestat senses a rapid increase in duct air temperature and at 125 o F (factory setting) turns the air handler off. Clogged Condensate Pan Drain Two condensate pan switches monitor the water level in the condensate pan. If the water level rises in the pan the switches turn off the unit and send an alarm signal to the controller. Loss of airflow A differential pressure switch in the blower monitors the airflow in the system. In the event of a loss of air flow through the unit the switch sends an alarm signal to the controller. Clogged filter A differential pressure switch in the blower monitors the pressure drop across the filters. In the event of high pressure differential across the filters the switch sends an alarm signal to the controller. Optional Features CeilStat I Electronic Thermostat/Humidistat The CeilStat I temperature and humidity controller incorporates temperature and humidity control in an attractive, wall mounted unit. This line powered, backlit system incorporates several salient features: * Manual override * 7 day programming * Programmable Fan * Adjustable Differential * Compressor Short Cycle Protection * Air Filter Monitor * 4 Hour reserve for settings * Status Indicators * Humidification in heat or air circulation modes * Hidden Service Level * Condensation Control CeilStat II Internet Accessible Thermostat/Humidistat The CeilStat II temperature and humidity controller incorporates temperature and humidity control in an attractive, wall mounted unit.
