CondenserRefrigerant condensation against cooling water or another refrigerant.
Cascade exchangerCO₂/ammonia or refrigerant-to-refrigerant phase-change service.
EconomizerSubcooling, flash-gas management and system-efficiency improvement.
Oil coolerCompressor lubrication-oil cooling with compact installation.
Heat-pump exchangerHigh-temperature condensation and heat-recovery duties.
Why PSHE for refrigeration
Low charge, high pressure and compact installation
- Small internal volume reduces refrigerant inventory
- Welded construction supports ammonia and high-pressure CO₂ duties
- High heat-transfer coefficient enables small approach temperatures
- Compact footprint suits packaged skids and machinery rooms
- Flexible plate pack tolerates start-stop and defrost cycles
- Suitable for evaporation, condensation and sensible cooling
