ALFA JF air to water units is ideal for heating water in residential and public buildings. Compact and lightweight design ensures maximum heat transfer by utilizing a series of 3/8" copper tubes with a high density of aluminum fins. Water to air heat exchangers are used to transfer heat from hot water to air. They are commonly used in outdoor boiler applications when hooking up units to existing forced air furnaces. ALFA 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. ALFA water to air heat exchangers canada are also suitable for liquid cooling applications and a number of other liquid to air and air to liquid heat transfer applications.
ALFA uses aluminum for fin material for higher heat conductivity. Fin density is an impressive 12 fins per inch. This unique design allows for heating loads of 50,000 to 60,000 Btu per square foot. Even though the fin density is high, the flow resistance through the coils is surprisingly low. Consists of 1 supply and 1 return copper manifolds with smaller diameter copper tube coils running from side to side on the heat exchanger. The tube coils are accompanied by aluminum fins, which purpose is to maximize heat transfer between water and air mediums. The structure is encased in a metal frame to reinforce the construction of the air to water heat exchanger. As hot water or other suitable solution enters the supply manifold of the water to air heat exchanger, it is separated into the tube coils, which carry it throughout the heat exchanger to the return heat exchanger. The process is similar with cold water or other cooling liquid when the heat exchanger is used for cooling applications.
All ALFA heat exchangers go though a strict quality control and a high pressure leak test to assure quality and long-lasting performance.
