New Cascade Heat Exchanger Technology
Colmac Coil Manufacturing is pleased to announce the introduction of its new Shell and Helix heat exchanger intended for use in Ammonia/CO2 cascade refrigeration systems. The new heat exchanger design offers the following advantages and benefits:All stainless steel construction for corrosion resistance and long life. Compact - large heat transfer surface in small volume. Cost effective compared to other heat exchangers in the market. High tubeside (CO2) pressure capability - as high as 1,700 psig (119 bar). Multiple helix design permits expansion and contraction of tubes during large changes in temperature and pressure with very low resulting strain and stress reducing the risk of failure and leaks. Nesting of the multiple helically formed tubes in both radial and axial directions results in equal spacing of the tubing and uniform flow distribution on the shellside. Multiple shell side connections allow reversing the flow of the ammonia and CO2 - permits reverse cycle hot gas defrosting. US and International Patents Pending.
