Product: ColdZone Dual-Pak Condensing Units
Description: This product offers two scroll compressors in medium- and low-temperature models that range in size from 1 to 4 hp, which can be mixed and matched to meet specific applications. The unit works like a mini-rack system. It has externally mounted service valves for quick access from the exterior, and removable top and side panels. For operating stability and increased system effectiveness, the units feature a 70°F floating head pressure control valve and an integral subcooling circuit that allows saturated liquid to flow from the receiver to the condenser, where the refrigerant is subcooled by ambient air. This provides an average of 3° to 5° of subcooling for higher operating efficiency while assuring optimal expansion device operation.
