RSH - Patented Capacity Control

Frascold's patented Reduced SuctionHead technology allows our reciprocating compressors to run unloaded indefinitely. Unlike standard capacity control, RSH capacity lets the compressor run without overheating while energized. This revolutionary feature provides application flexibility while reducing heat, vibration and damage from unloading stress.
