Low Temperature & Ammonia
Overview
The Teqtive two-stage brine chiller splits compression into two steps to reach −25 °C to −45 °C more efficiently than a single-stage machine. Lower compression ratio per stage means lower discharge temperatures, better efficiency and longer compressor life.
Two-stage machines are available from 1 TR to 200 TR and fill the gap between standard brine chillers and cascade systems.
