Overview The modular, Floor Mount computer room air-conditioning system offers efficient, effective and economical cooling for a variety of spaces. Computer room environmental requirements now reach far beyond the confines of the traditional data center or computer room to encompass a larger suite of applications, referred to as technology rooms.
Scalable Solution for Critical Environments Temperature and Humidity Design Conditions Maintenance of temperature and humidity design conditions is critical to the smooth operation of a technology room. Design conditions should be 72-75°F (22.224.8°C) and 45-50% relative humidity (R.H.). As damaging as the wrong maintained conditions can be, rapid temperature swings can also have a negative effect on hardware operation. This is one of the reasons hardware is left powered up, even when not processing data.
Scalable Solution for Critical Environments Dedicated Dehumidification Cycle A dedicated dehumidification cycle allows the system to increase latent capacity without overcooling, lowering the requirement for reheat and humidification. This is accomplished by operating one compressor, isolating a portion of the coil from the refrigerant flow and lowering the evaporator temperature when dehumidification is required.
Scalable Solution for Critical Environments Humidity Control Increasing heat densities in data centers are leading to more hot spots and higher return temperatures to the precision air conditioners. When hot spots exist in close proximity to the air conditioner, temperature and humidity readings can be misleading to the overall room conditions. As temperature increases, the relative humidity (R.H.) level (the amount of moisture the air can hold at a given temperature, shown as a percentage) decreases.
Scalable Solution for Critical Environments Glycol-Cooled Configuration Glycol-cooled systems are completely charged and factory tested in a sealed system for reliability. In mid to low ambient climates, an economizer coil can be used to increase efficiency and extend compressor life. Economizer operation greatly reduces the energy consumption of the system. Water regulating valves control head pressure.
Standard Features Double Skin Panels The frame is bolt together 12 gauge formed steel for maximum strength. Cabinet is serviceable from the front. All exterior panels and corner posts on the frame are powder coated for durability and an attractive finish. Front exterior panel crowne is 16 gauge. All other panels are double skin, 24 gauge exterior, 24 gauge interior with 1 ½ lb. (.68 kg) per cubic foot insulated for quiet operation. Insulation is CFC-free and recyclable.
Standard Features Steam Generating Humidifier The humidifier utilizes a pure steam generator specifically designed for precision environmental control. The pure steam eliminates contaminating mineral deposits, potentially harmful bacteria, white dust and excessive humidity. The humidifier requires little scheduled maintenance. Automatic flushing combined with a communication link to the controller signals when the canister is to be changed.
Optional Features Brazed Plate Condenser Water- and Glycol-cooled systems employ a brazed plate heat exchanger. The condenser is equipped with clean out plugs. Rotalock valves make removal of the brazed plate condenser easy for maintenance and replacement. Smoke Detector The factory-installed smoke detector is designed to sense smoke in the return air stream. Upon detection of smoke, an audible and visual alarm on the microprocessor will be activated and the unit will be immediately shutdown.
Optional Features Additional Programmable Input/ Output Interface Modules Each system is equipped with up to 3 additional discrete input/output modules for a total of 16 input/outputs. Each interface module is programmable with outputs that can map from any system alarm through the microprocessor controller. Inputs are capable of mapping to outputs as a system alarm or custom alarm.
Microprocessor Controller Microprocessor Controller The microprocessor controller is standard on each system. The controller provides precision control for the demanding requirements of: • Data centers • Control rooms • Clean rooms • UPS rooms Open Architecture The NetworkAIR FM protocol is open for integration with all building management systems. Communication interface on the system can be MODBUS RTU RS485.

Guidelines for Installation The NetworkAIR FM provides reliable, accurate temperature and humidity control of computer rooms, laboratories, and other environments that require close tolerance control. The unit incorporates the latest system design innovations to provide you with optimum efficiency, reliability, and accuracy of control. The NetworkAIR FM system will provide years of trouble-free service, when installed and maintained by technically qualified personnel.
Guidelines for Installation Receiving the unit Your NetworkAIR FM unit has been completely tested and inspected prior to shipment. To ensure that you have received the unit in excellent condition, perform a careful inspection of the crating and the unit immediately upon receipt. Verify that all parts ordered were received as specified and that the unit is the correct size and voltage necessary to fulfill your environmental control needs. Report any damage discovered to the freight carrier.
Guidelines for Installation Water supply to humidifier 1. The humidifier fill valve orifice is sized for supply water pressure from 15 PSI (103.4 kPa) to 150 PSI (1034 kPa). 2. For cases above 150 PSI (1034 kPa), install a pressure-reducing valve in the water feed line to the unit. 3. With extremely dirty or muddy water sources, proper filtration is required on the unit’s incoming water line. 4. DO NOT use softened water with the humidifier. Softened water is too conductive. 5.
