Features
Serpentine evaporator coil is a type of heat exchanger that utilizes plates and finned chambers to transfer heat between fluids, usually gases. It features "sandwiched" passages with fins to enhance performance. Available designs include crossflow and counterflow, with various fin configurations such as straight, offset, and wavy fins.
Serpentine heat exchangers are the most compact and versatile solution for 3kW heat rejection or cooling. They are ideal for use in refrigerant condensers, evaporators in compressorized and pumped loop systems, and non-condensing cooling applications, delivering excellent heat transfer efficiency, reliability, and ease of integration.
Venttech offers customized serpentine evaporator coils tailored to client specifications. Our manufacturing facility has the capacity to produce up to 150 tons per month and provides a one-year warranty.
