Compact spiral heat exchangers ease maintenance
This company’s Spiral Heat Exchangers are circular heat exchangers with two spiral channels, each in one closed chamber. The flow of the two products is countercurrent, which makes it possible to have a close temperature approach between the two medias being treated in the heat exchanger. They are designed for demanding fluids with very high viscosity. Welded spacer studs to increase the turbulence and heat transmission. They are said to offer an alternative to plate and tubular heat exchangers for handling dirty media. — Sondex A/S, Sondex, Denmark
