Direct Expansion Coils

Face Split, Row Split, and Intertwined circuiting are all different options offered for proper refrigerant distribution. Will match existing size and capacity!

Our DX evaporator coils are available in 1/2”, 3/8”, 5/16” or 5/8” OD copper tubes with a distributor based on the coil performance and specific refrigerant. We are one of the few manufacturers that offers 5/16” tubing for DX and condenser coils. Capital Coil offers face splits, row splits, and intertwined options. We also offer insulated cabinet/drain pans for ducted applications. Typically, the connections for DX coils are sweat connections. We do not offer thermal expansion valves with our DX Coils. Carrier, Trane, McQuay, York/JCI, Heatcraft are all manufacturers that we can easily duplicate often at a fraction of the cost of a new coil from the OEM and twice as fast.
