Selecting evaporator coils (DX coils) for your commercial property or manufacturing needs

In commercial HVAC systems, two related coils are involved - condenser coils and evaporator coils, also called direct expansion (DX) coils. I’ll discuss condenser coils in a separate blog.

Evaporator coils are heat exchangers used to heat or cool an office building, manufacturing plant, refrigeration system, or other commercial application. Evaporator coils are located inside the building, while condenser coils are located outside the building.

Evaporator coils for commercial and manufacturing applications typically have between 4 and 8 rows. The most common tube diameters we see are 3/8" and 1/2". Standard applications include comfort heating and cooling, dehumidification, refrigeration, and reheating.

We make it easy for you to record the specs you need for evaporator DX coils using the drawings provided in the Blank Drawings section of the website. Under each type of coil, there are numerous blank drawing options. Under Evaporator DX Coils, we provide drawings for configurations such as DX Coil Single Circuit, DX Coil with Suction Facing Downstream, DX Coil Dual Circuit Interlaced, DX Coil Dual Circuit Split by Face, to name a few.
