Heat Exchanger Water to Air 18 x 20 in 133K BTU Copper
✅ Warm a space faster. Copper plates and brazed contact points move heat from water into the air stream.
✅ Fit it in tight plant. The 18 x 20 in plate area packs at least 133K BTU into a compact frame.
✅ Worry less about leaks. Each unit is vacuum brazed and leak tested before it ships.
✅ Use it on several systems. It suits wood furnaces, forced air heating, solar loops and engine cooling.
Move heat from water into the duct
A water-to-air heat exchanger with an 18 x 20 in plate area, built in copper with copper-brazed joints and epoxy-coated fins. It suits outdoor wood furnaces, forced air heating, solar heating and engine cooling. The outlet sits above the inlet, and the unit handles up to 2.5 MPa.
