Spiral Roll Bond Evaporator Coil Heat Exchanger for Refrigeration Parts
consists of one inner twisted tube and one outer tube. Heat and cold liquid seperately flow in inner tube and between tubes for heat transferring..Its advantages: pressureproof, quakeproof,antide formed,dirtyproof,oil returning smoothly, safe and high-quality,leakproof, convenient,
resonable price,well applied into heat pump system.
Coaxial heat exchanger
Tube in tube heat exchanger
