SWEP All-Stainless™ products are developed for systems demanding 100% stainless steel components, and for high temperature applications. They can be used with fluids that are corrosive to copper or for sensitive applications where copper and nickel contamination must be avoided. SWEP’s unique process technology enables a compact product with minimal material usage relative to its mechanical strength. The B85S is our medium-size high-capacity model. It is the perfect choice for most types of low-capacity chiller applications and high-performance heat pumps. It covers a wide capacity range in district heating substations and is a proven oil cooler for compressors and hydraulics.
