Split Air-cooled Chillers

Split Air-Cooled Chillers

Split Air-Cooled Chillers, the SAR-Series manufactured by Whaley Products, Inc., have two components, one installed inside and one installed outside. This system is best suited for customers in low ambient environments that require running just straight water for the process fluid and the heat from the condenser needs to be dissipated outdoors. Frequently multiple SAR-Series units are selected in conjunction with a C-Series heat transfer pump tank system to provide high redundancy for critical heat load applications. The SAR-Series systems are typically purchased initially with a single air-cooled condenser with a heat transfer pump tank to start with. With the initial setup, WPI can size the heat transfer pump tank system for unlimited capacity. One of the benefits of the SAR-Series is its redundancy. By using multiple condensers, it gives the high redundancy you need for critical heat load applications that cannot have any downtime. With the initial setup, WPI can size the heat transfer pump tank system for unlimited capacity. This system can be used for any heat load applications due to having no restrictions on capacity. The heat transfer pump tank system’s reservoir can be sized for whatever your desired volume is which gives you more temperature stability as well as the ability to “store btu/hr” to help minimize chiller size. The SAR-Series coupled with the C-Series Heat Transfer Pump Tank System also allows for multiple configurations and flexible design. WPI can provide but are not limited to redundant pumps, variable frequency drives, different tank materials, different plumbing materials (including those for food applications), and many more.

Split Air-Cooled Chillers

Split air-cooled chillers are made up of 2 main components. The first component is an air-cooled condenser unit, which is typically installed outdoors in order to dissipate the heat to the atmosphere. The second component is the Heat Transfer Pump Tank Skid, which is typically installed indoors. The Heat Transfer Pump Tank Skid contains evaporator(s), refrigerant liquid and suction line components, water/glycol reservoir, and pumps. One pump (chiller circulation pump) circulates the chiller’s evaporator to keep the chiller system’s reservoir tank at the target set point temperature. The other pump (process supply pump) pulls out of the chiller’s internal reservoir, circulates to your downstream application, and returns back to the chiller’s internal reservoir.
