Product Description

Variable Speed Screw Compressors--Environment friendly, Energy Saving Star

Crownwell develops its variable speed screw compressors to be high energy efficiency. At full load, the variable speed compressors will produce the most air using the least energy. Even more important, Crownwell will guarantee these efficiencies down to loads as low as 25%. A conventional, fixed-speed air compressor is controlled by a suction control valve that modulates between open and closed positions. But using the suction valve to meet system air demand results in extreme pressure fluctuations and wasted energy, greatly reducing efficiency whenever the compressor operates outside its optimum performance range. Using a frequency inverter and the variable-frequency motor, Crownwell compressors deliver the only true variable speed drive. With a true VSD, air is delivered at a constant pressure, regardless of demand, at maximum efficiency. Remarkably, Crownwell compressors achieve constant pressure and maximum efficiency across their entire operating range, from 100% loaded down to as low as 25% loaded.
