Features/Benefits (cont) These vertical package units offer flexible economical air conditioning for today’s office environment. Compressors are mounted on vibration isolators. Each compressor is equipped with a coaxial tube-in-tube condenser for maximum heat transfer efficiency and performance. All condensers are rated at 450 psig operating refrigerant pressures (600 psig for Puron® refrigerant models) and 400 psig water-side pressures. Evaporators are enhanced fin, rifled tube type for maximum performance. Large face areas ensure low airside pressure drops and reduced face velocities to...

Factory-installed options Waterside economizer — A condenser water pre-cooling coil located before the direct expansion cooling coils allows the use of the condenser water to provide free cooling. When the condenser water temperature is less than an adjustable set point or more below the return-air temperature, condenser water is directed to the economizer coil to obtain free cooling. When free cooling is available the economizer coil functions as the first stage of cooling. The economizer coil valve can be modulated to control discharge-air temperature when the economizer can meet or...
