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.
