Teflon coating is now available on exterior surfaces of liquid-cooled and air-cooled heat exchangers. Teflon resists the corrosive characteristics of many chemicals common in processing applications. A Teflon coating can provide an economical alternative to constructing housings from stainless steel or exotic metals. The coating is easy to clean and offered in a variety of colors. Unit pictured is being used to cool the airflow in a closed-loop processing application. The airflow is cooled by methanol that flows through a copper tube inside the housing. Tubes are expanded into multiple fin plates to increase the heat-transfer surface. The core can be removed for inspection or cleaning without disconnecting the airline. Design was pressure tested at 75 PSIG.
