Direct Coil is an advanced manufacturer of custom-designed Round Tube Plate Fin Heat Exchangers (Coils) for the OEM, Custom & Replacement markets. Our coils can be selected using our proprietary coil selection software on their size or performance. Our wide range of tube sizes, fin spacing, and coil connection orientations allow for a drop-in coil fit. 100% of our coils are pressure tested for leaks to ensure we are producing quality products.
Our coils use mechanically expanded seamless copper tubes, that are manufactured to ASME standards and available with either smooth or enhanced internal surfaces. They are available in 5/16”, 3/8”, 1/2” and 5/8” Tube Diameters. Plate type die-formed aluminum fins are available as either flat, corrugated, or lanced with straight or rippled edges, with 5 different fin thickness options. Our fins are fully collared and have a staggered tube pattern for enhanced heat transfer and lower air friction. Our coil casings are available in a wide variety of thicknesses & materials (including galvanized steel, aluminum, stainless steel, and copper). Our optional corrosion-resistant materials and protective coating help increase the service life of the coil.
Water Coils
CSA & UL Approved
Direct Coil Water Coils are designed for comfort conditioning and heating applications that have been extensively tested for heat transfer between air and fluid (water or water-glycol mixtures). Turbulators are available for applications that require additional capacity at a lower flow rate. Chilled Water coils can be constructed with intermediate drain pans, to avoid moisture carryover on taller coils.
Evaporator Coils
CSA & UL Approved
Direct Coil Evaporator Coils (aka Direct Expansion Coils) are designed to deliver maximum heat transfer efficiency under a wide range of operating conditions.
We offer a wide variety of coil circuiting, including Interlaced/Face split to meet performance requirements. Evaporator coils are counterflow circuited with optimized size suction headers and refrigerant distributors. Distributor tubes are equal lengths to ensure equal distribution of refrigerant into each circuit.
To ensure product durability under thermal expansion and vibration, the coils are manufactured with the highest quality materials and standards.
Condenser Coils
CSA & UL Approved
Direct Coil Condenser Coils are designed for the high pressure and temperature associated with refrigeration condensing.
Whether used for condensing or heat reclaim applications, our coils are engineered to work with a large variety of refrigerants. To ensure product durability under thermal expansion and vibration, our coils are manufactured with the highest quality materials and standards.
Steam Coils
CSA & UL Approved
Direct Coil Steam Coils are made with heavy walled copper tubes and headers and are available with a variety of connection locations and casing options to meet any mounting configuration.
Standard Steam coils are suitable for a wide range of heating applications such as preheat, boosters, reheat, duct heaters, process air & gas, and many more. Distribution Steam coils (Non-Freeze, Tube-in-Tube) are available for applications where condensate freezing is a concern.
Booster Coils
CSA & UL Approved
Direct Coil Booster Coils are designed to maximize capacity in applications where water flow is limited. High performance is achieved through the coil circuiting, which increases water velocity.
The coils are offered with 1 – 4 rows of continuous tubes. MPT connections are provided at the inlet and outlet tube locations. Slip and Drive or Standard casing options are available.
