Refrigeration heat exchangers
from 50 kW to 3,000 kW
Thanks to a very high performance exchange tube, COREVA direct expansion evaporators guarantee high thermal transfer using minimal fluid. Copper or steel for cooling standard fluids (fresh water, glycol/water mix, alcohol, brine etc.), Stainless steel for corrosive fluids (demineralised water, some thermal fluids etc.), Resistant materials for use at low temperatures (<-20°C), Baffles made from materials using anti-corrosion polymers. Numerous options and variants are possible to facilitate integration (a range of refrigerating circuits, compressor supports, customised baffling etc.).
