RCCD stand for Refrigeration Capacity Control Device. It is a compact device comprised of hot gas bypass valve (HGBV), liquid injection valve, and a proprietary mixing chamber that eliminates the risk of compressor liquid slugging.

Rawal APR Control: the inexpensive air conditioning modulation solution. Turns any new or in-place Direct Expansion (DX) air conditioning units and heat pumps into a modulating variable-capacity system – extending the cycle of operation and continuously matching capacity to changing load conditions.

The RCCD is of benefit in all traditional HVACR systems that use fixed displacement / fixed speed compressors. RCCD greatly improves performance in applications like: Spaces with large variability of loads like schools, libraries, office spaces, conference rooms etc.
