Direct Coil offers Booster Coils for coils are designed to produce high capacity with limited water quantity. High performance is achieved by the increased water velocity obtained from the circuiting of these coil types. The booster coils can be properly sized using our proprietary software.

Duct booster coils are for use with hot water with 1 or 2 rows of continuous tubes and return bends. Male or Female-threaded connections are provided at the inlet and outlet tube locations with optional manifold headers.
