Retekool offers a wide selection of standard size finned coil heat exchangers (water to air heat exchangers) with sizes 12” x 12" and above. These units are most commonly used for forced air heating and cooling systems, such as with indoor and outdoor wood furnaces, boilers, stoves and many others. Water to air heat exchangers are also suitable for liquid cooling applications and a number of other liquid to air and air to liquid heat transfer applications where liquid temperature does not exceed 350F and operating pressure is at or below 360 psi. 1" sweat inlet/outlet connections are standard on all models.
Water to air heat exchangers are used to transfer heat from hot water to air. Water to air heat exchangers are commonly used in outdoor boiler applications when hooking up units to existing forced air furnaces.
Water to air heat exchangers are available in many sizes for each individuals needs.
These exchangers are designed to transfer hot water heat through 3/8'' seamless copper tubes with high density aluminum fins, with minimal flow resistance. Exchanger housings are manufactured with galvanized steel. Headers are made from copper and have a 1” ID.
