The Rawal Unloader is a unique (and Patented) refrigeration component that provides modulating unloading capability to non-unloading Dx (direct refrigeration) systems. The Rawal device is used to allow Dx systems to unload to as much as 50% of the system’s capacity. This reduction is done with a response that mimics a modulating chilled water valve (smooth operation from full capacity to minimum capacity).

Unloading below 50% is not recommended to ensure proper oil circulation around the refrigeration system.
