This immersion heat exchanger is designed to resist hot spots
This Immersion Coil Heat Exchangers have been proven worldwide in a vast range of applications. These heat exchangers have corrosion resistance that is second only to diamond, says the company, and benefit from the inherently non-stick characteristics of the fluoropolymer materials of construction that are used. These include polytetrafluoroethylene (PTFE), fluorinated ethylene propylene (FEP), perfluoroakoxy (PFA) and others, which help to resist fouling, scale buildup and clogging. These heat exchangers do not have a single tubing weld joint (which can be susceptible to failure over time). This helps to maintain optimal heat transfer efficiency over the entire lifecycle of the system and ensure uniform heat transfer between steam and acid, according to the manufacturer. — Fluorotherm, Parsippany, N.J.
