Split-Pak™ Remote Refrigeration Systems
Split-Pak remote condensing units consist of a condenser coil, compressor, receiver tank and other components assembled on a common base. Remote systems may be used with walk in coolers and freezers.
As the name implies, remote systems are located away from refrigeration equipment, frequently outside a building or on a roof. Remote location allows heat produced from the system to be released outside without increasing inside building temperatures or the air conditioning load.
Split-Pak condensing units are specially designed to function in high temperature environments with a standard weather hood to protect from the elements. All components are pre-wired and factory mounted. Compressor choices include hermetic (compressor and motor sealed inside one housing) and compliant scroll (two interleaving scrolls compress refrigerant contained inside). Units that are six H.P. and above used in freezer applications are equipped with the Master Controller electronic controller system as standard.
Split-Pak evaporator coils, also referred to as unit coolers, are furnished as part of a remote refrigeration system for walk in coolers and freezers. Their main purpose is to blow cold air inside the walk in structure and keep stored products cool.
Evaporator coils are ready to mount in position on a walk in and are available with air (off cycle) defrost, electric defrost or optional reverse cycle defrost when equipped with the Master Controller Reverse Cycle Defrost system.
