Water-to-Air Heat Exchanger Coil, 18 x 18 in, 120K BTU

Water to air heat exchanger coil delivers fast, efficient heat transfer for hydronic heating and cooling—ideal for outdoor wood furnace tie-ins and forced-air applications. Built with seamless copper tubes and aluminum fins, it maximizes thermal conductivity while staying compact for easier integration. A large 18 x 18 in finned surface and multi-row tube design helps move more heat where you need it, with vacuum-brazed construction and leak testing for dependable operation.

Designed for workshops, farm buildings, grow rooms, and residential hydronic systems, this finned tube HVAC coil supports heating and cooling loops where space, airflow, and output matter. The 217-fin pack and three rows of 3/8 in copper tubing increase surface area for consistent performance, while galvanized steel plate construction adds rigidity for installation. Add it to your air handler or duct box to convert hot or chilled water into usable air temperature control—grab yours today and get your system ready for the next season.
