gForce GT R-410A Single Circuit Air Cooled, Water/Glycol Cooled 7 to 46 kW
… the pioneer and builder of the most complete line of precision cooling equipment Back in the late 1960’s and early 70’s with the advancement of the computer and computer rooms, precision environmental control equipment with high sensible cooling ratios became a necessity. Data Aire, a division of Supreme Aire, worked with leading computer facility engineers to develop one of the first down discharge air conditioning units for raised floor application.

- GT IMPROVED PERFORMANCE and REDUCED MAINTENANCE MISSION CRITICAL COOLING gForce by Data Aire provides the most advanced features in mission critical cooling equipment available on the market today. These units are the most efficient and economical while complying with strict environmental requirements. Backward curved fans discharge air radially allowing for uniform static pressure across the raised floor.
INCREASED THERMODYNAMIC EFFICIENTIES R-407C is a blend of three refrigerants and has characteristics similar to R-22. R-410A is a blend of two refrigerants and has a higher volumetric cooling capacity but operates at higher pressures than either R-22 or R-407C. The choice of the environmentally friendly refrigerant is yours. gForce’s design incorporates rifled tubing cooling coils. Rifle tubing is similar to borings in a gun barrel which forces the bullet to rotate.
DESIGN FEATURES FRAME AND CABINET bility of refrigerant or oil leaking into the controlled space or environment. Scroll compressors also bring a combination of reliability, efficiency, and improved system sound performance.
CONTROL SYSTEM DATA ALARM PROCESSOR-III The Data Alarm Processor-III (DAP™ III) offers the definitive answer for precision environmental control. The DAP-III control system not only controls and monitors temperature, humidity, airflow and cleanliness, it provides component run times, alarm history and an automatic self-test of the microprocessor on system start-up. All messages are presented in a clear vernacular format and sequentially displayed on a backlit, liquid crystal display (LCD).

OPTIONS Energy Saver Coil - The Data Aire Energy Saver Coil is built into the system to provide total required capacity. Whenever the incoming water/glycol temperature is below 45° F/7.2° C, Energy Saver cooling is available. Energy Saver mode operates in the following range: Return air setpoint plus deadband plus two degrees. The Energy Saver will operate providing there is a need for cooling. The valve will open at setpoint plus deadband.
OPTIONS, continued Site Monitoring Devices the evaporator under full load will maintain pressure on the leaving side of the hot gas bypass valve to keep the valve port closed.
