Optimized Phase-Change Heat Transfer: Industrial chilling applications rely on continuous, rapid evaporation and condensation phases. To maximize this thermal loop efficiency, our chiller condensers and evaporators utilize internally enhanced copper tubes. This grooved helical design increases the effective internal surface area and breaks the fluid boundary layer, delivering heat transfer coefficients far superior to smooth-bore alternatives.
DX & Flooded Evaporator Options: Sized and engineered to match your compressor curves perfectly, we fabricate both Direct Expansion (DX) and flooded shell and tube evaporators. Our thermal designs prevent compressor oil-logging, ensure uniform liquid refrigerant distribution across the tube bundle, and achieve tight temperature approaches to boost the overall chiller Coefficient of Performance (COP).
Strict Pressure Integrity & Sealing: Handling high-pressure modern refrigerants requires strict manufacturing safeguards. Our tube sheets are CNC-drilled, and tube-to-tubesheet joint interfaces are hydraulically expanded under computerized torque limits. This mechanical process prevents refrigerant-to-water cross-leakage, and completed assemblies undergo strict helium leak testing and hydrostatic testing up to 28 Bar.
Every unit is modeled with specific thermodynamic profiles. Below are the key engineering specifications built into our Chiller designs:
Helically grooved inner-tube profiles increase internal boundary turbulence , boosting heat rejection rates significantly.
Designed with independent multi-refrigerant circuits, allowing part-load energy efficiency and compressor redundancy.
Engineered in compliance with TEMA Class C specifications and ASME Sec VIII, ensuring high-end manufacturing safety.
