Standard exchangers, particularly made for heavy duty ever with medium pressure ranges. The composition can be made with different choise of materials, all sort of combinations make this type of exchangers versatile enough to solve any problem of fluids, flows, even with high duty rating. Cooling surfaces from 0.3 to 30 sq. mt. For each standard model we’ve provided two types, “ A ” for Iow flowrate, “ B ” for high flowrate.
