Enhance Refrigeration Compressor Protection with High-Performance Surge Control

Prevent compressor trips and protect refrigeration systems with advanced antisurge strategies.

Refrigeration compressors face unique surge risks that standard control strategies often overlook. Unlike normal gas compression circuits, refrigeration systems experience phase changes and complex load variations that can trigger rapid, unexpected surge events, especially during driver malfunctions or load fluctuations.

This white paper explains why refrigeration compressors require the same high-performance, fast-acting antisurge protection used in conventional gas compression. It covers best practices for antisurge loop design, the critical importance of cooling recycle gas through quenching or sparging, and how dynamic coordination between surge control and quench systems prevents compressor trips.

You’ll also explore the challenges of calculating suction flow rates in multistage refrigeration compressors and the need for accurate inferential algorithms to maintain safe and efficient operation.

Whether you are designing, upgrading, or optimizing refrigeration compression systems, this paper offers actionable guidance to improve reliability, protect assets, and maintain stable operations.
