Water to air heat exchanger transfers heat efficiently between liquid and airflow, helping stabilize temperatures in hydronic heating, cooling loops, and DIY thermal management setups. This 16" x 16" core uses 3 rows of 3/8" copper tubes with dense aluminum fins to increase surface area and airflow contact. Copper-brazed construction and a thickened interface are built for high-pressure, high-temperature operation where reliability matters.

Designed for builders who need efficient, space-conscious heat exchange, this copper-and-aluminum radiator-style core suits workshops, garages, off-grid systems, and custom HVAC/hydronic projects. The dense fin pack increases effective surface area for better thermal transfer, while the brazed construction supports higher working pressures than light-duty alternatives. Confirm your airflow, mounting space, and port routing before install to match your system layout. Grab yours today to keep your loop running at steadier temperatures.
