Sanitary Tube -in- Tube Heat Exchangers
Precision Heat Transfer for High-Stress Thermal Applications
Engineered in accordance with applicable ASME design guidelines, sanitary tube-in-tube heat exchangers are ideally suited for processing fluids subject to large temperature differentials. The independent inner and outer tubes are free to expand and contract individually, reducing thermal stress and supporting long-term mechanical integrity under repeated thermal cycling. This inherently flexible design optimizes heat transfer efficiency while maintaining smooth, cleanable flow paths, low hold-up volume, and full CIP/SIP compatibility—making it a proven solution for regulated processes where performance, purity, and reliability are non-negotiable.
Small Footprint. Serious Pharmaceutical Performance.
Exergy sanitary tube-in-tube heat exchangers feature a precision-engineered dual-tube configuration, with an inner and outer tube coiled together to form an exceptionally compact, high-performance thermal solution. This robust design minimizes thermal fatigue, maximizes heat-transfer efficiency, and reduces system footprint—making it ideal for high-temperature, high-pressure, and low-flow pharmaceutical processes.
