Open type series for Ammonia
In the industrial process refrigeration systems operating with ammonia, in particular those for the production and food processing, but even in marine sector, strong and efficient compressors are required.
Our range of compressors for NH3, driven by the electric motor by means of joints for direct transmission or by belts and pulleys, perfectly meets those needs, thanks to robustness, compact overall dimensions and high efficiency.

The range includes three models with 6-cylinder and displacement from 146 to 188 m3/h (50Hz) and a wide selection of accessories that multiplies the versatility.

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.
