Industry application

Heat Exchangers for Refrigeration

Efficient evaporation, condensation and heat recovery.

Application engineering

Start with the process—not a catalogue model.

Refrigeration selection must account for refrigerant properties, phase distribution, oil return, fatigue, defrost and pressure class. HEXNOVAS separates standard HFC/HFO duties from ammonia and transcritical CO2 applications.

Industrial ammonia refrigeration

Semi-welded evaporators, condensers and heat-recovery interfaces for cold stores and food plants.

Transcritical CO2

Reinforced high-pressure BPHE platforms for gas cooling, evaporation and heat recovery.

Commercial refrigeration

Compact evaporators, condensers and hot-water recovery for supermarkets and packaged systems.

Compressors & air dryers

Oil cooling, aftercooling, moisture removal and compressed-air heat recovery.

Selection basis

Information that determines the right exchanger.

A reliable selection requires the complete operating case, not only heat duty. These factors are reviewed together before model sizing.

Refrigerant and phase-change condition
Design pressure, fatigue and applicable approval
Distribution, superheat and oil management
Defrost cycle and freeze protection
Secondary fluid and allowable pressure drop

Technology fit

Products commonly used in this application.

The final technology depends on media, pressure, temperature, fouling, cleaning and lifecycle requirements.
