Cesaroni Technology Inc. is at the forefront of developing high performance polymer heat exchangers under the brand name PolyCoil. These heat transfer systems have been developed for a variety of applications ranging from; HVAC equipment, small pleasure craft, geothermal, evaporative fluid coolers, military vehicles, automotive, thermal ice storage systems, and more. The all-polymeric construction makes them corrosion resistant and much less susceptible to damage when compared to current systems with fragile metal fins. The light weight of the systems makes installation simple. This makes them ideal for harsh environments.
