Below is a list of Spiral Heat Exchangers manufacturers from Paterson, New Jersey. A spiral heat exchanger is a type of shell and tube heat exchanger design that consists of a spiral body made from two flat surfaces, typically metal strips, which are coiled to form two spiral channels. Commonly used for applications including digester heating, pasteurization, heat recovery, pre-heating and effluent cooling, spiral heat exchangers offer the benefit of increased floor space due to their relatively compact size.
