Slip and drive booster coils are water coils for HVAC heating, reheating and cooling systems. These units have formed aluminum fins, smooth copper tubing and galvanized steel casings. When installed, the coil becomes an integral part of the duct system. The design of the top and bottom plates allows for quick and easy installation of these coils into new or existing slip & drive ductwork with minimal time and material investment. A wide range of coil sizes are available (custom sizing as well) to match various duct geometries.
