Nexson Group, the French expert in welded heat exchangers, designs and manufactures the GREENSPIRAL™ spiral plate heat exchangers a compact, fully welded solution engineered for extreme industrial conditions. Thanks to its single-channel, self-cleaning design, this exchanger is three times more efficient than tubular models for processing highly fouling, loaded, or viscous fluids. Operating from -100°C to 500°C and up to 100 bar for high-performance models, GREENSPIRAL™ is the benchmark technology for waste heat recovery and decarbonization in the refining, petrochemical, and heavy industry sectors.Nexson Group, the French expert in welded heat exchangers, designs and manufactures the GREENSPIRAL™ spiral plate heat exchangers a compact, fully welded solution engineered for extreme industrial conditions.
