Whaley Split chiller systems are used in applications where the water pump tank and evaporator are installed indoors near the process on its own dedicated skid. The air cooled condensing unit includes the compressor, condenser, and fans and is installed outside on the roof or on a slab beside the building.

WPI offers high efficient 410A systems,  SAR1.5-10S (1.5-10ton single circuit) and SAR10-100D (10-100ton dual circuits) are available. 


A split chiller system is used when the condenser is installed less than 50 feet from the evaporator.  The inside unit includes the “TXV” thermostatic expansion valve, filter dryer, sight glass, pump and control panel with chiller/pump controls.  Circulation pump and supply pump, discharge check valves plumbed and wired with wiring diagrams and installation instructions.

The advantage of having the condenser outside is the is to reject the heat outside instead of dumping it into your plant.  A disadvantage is that these types of system are more permanent and you have less flexibility than a glycol system.   You can’t connect split systems in parallel like you can glycol chillers. Another disadvantage is because of the extra Freon piping there is more chance of Freon leaks.
