Product Data OMNIZONE™ 50BV020-064 Water-Cooled Indoor Self-Contained Systems and Water Source Heat Pumps 18 to 60 Nominal Tons Omnizone 50BV units offer: • Puron® (R-410A) refrigerant • High-boy modular units break down to fit through a standard, 36-in. doorway • Either two or four high-efficiency scroll compressors for efficient part load control, quiet operation and system redundancy • Suction and discharge Schrader valves on manifold gage connections Omnizone 50BV units are self-contained, water-cooled indoor cooling units or water source heat pumps. Flexible, efficient and economical 50BVC,J,Q,Y020-034 SINGLE PIECE OMNIZONE UNIT Units are available for constant volume (CV) or variable air volume (VAV) applications (with the exception of heat pumps) in both modular and singlepiece construction. Single-piece units are completely factory wired, piped and charged, ready for installation. Units use Puron (R-410A) refrigerant and have EERs (Energy Efficiency Ratio) up to 14.6. Units include a direct expansion evaporator coil, compressors, and water-cooled cleanable condensers. The VAV units include a single or multiple belt drive evaporator fan(s) with VFD (variable frequency drive) controlled motor and complete microprocessor control system. Optional water economizers and hot water heating may also be added. 50BVT,V,W,Z034-064 MODULAR OMNIZONE UNIT © Carrier Corporation 2013

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 600 psig operating refrigerant pressures 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 prevent condensate carry over and maximum moisture...

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 exceed...
