Open-type Two-stage Screw Refrigeration Compressor Unit
The Open-type Two-stage Screw Refrigeration Compressor Units from Lynxcool are specifically engineered for ultra-low temperature applications and large-temperature-differential environments. By utilizing a two-stage compression process (low-pressure and high-pressure stages), these units significantly improve volumetric efficiency and reduce energy consumption compared to single-stage units in deep-freezing conditions.
What is an Open-type Two-stage Screw Refrigeration Compressor Unit?
An Open-type Two-stage Screw Refrigeration Compressor Unit consists of a low-pressure (LP) booster and a high-pressure (HP) compressor working in series. This configuration handles the high compression ratios required for deep-freeze temperatures (down to -65℃) while maintaining lower discharge temperatures and higher COP (Coefficient of Performance).
Manufactured by Lynxcool in China, these units are optimized for R717 (Ammonia), R404A, and R507A, offering a reliable and eco-friendly cooling powerhouse for the most demanding industrial environments.
