Resistance To Liquid Slugging

The robust design of the Series R compressor can ingest amounts of liquid refrigerant that would severely damage reciprocating compressor valves, piston rods and cylinders.

Proven Design Through Testing and Research Test To Failure

It takes a little getting use to, but we MUST fail a lot of compressors in the laboratory so they don’t fail in the field. Without failures, there is no way to be certain whether the final design is conservative or potentially unreliable. The Compressor Accelerated Life Test is proven to induce failure. This test is designed to overstess all parts and quickly identify any weak elements. The test conditions are far more extreme than actual field applications. Engineers fail, redesign, fail, redesign, etc., until finally, reliability in the field is assured. Our leadership in helical compressor technology is recognized worldwide. It is the basis for the successful introduction of the reliable Trane Helirotor compressor — right from the start!
