Benefit of Material to Systems Application

Copper is not the preferred material for condensate draining of a cooling coil.  This is primarily due to the fact that condensate tends to be slightly acidic in nature and proves corrosive to the copper in some instances. In addition, the price of copper is also a deterrent.  PVC, being 4 to 6 times less expensive than copper, is the preferred material for condensate drains.  Some local codes may prevent PVC from being used and copper is then a likely substitute but, all three mechanical codes of the U.S. permit PVC.

Copper is sometimes used in the rare event the condensate is run from a rooftop or group of roof top units to a centralized drain area. Generally condensate is allowed to drain onto the roof of a facility and evaporate into the atmosphere. When draining a coil inside, the condensate is typically drained to a floor drain in the mechanical room or pumped to a drain using a condensate pump.

System Application and Material Usage

When used for condensate drains, copper is connected using copper fittings and solder, similar to domestic water applications using copper tubing. No special tools are required.  Internal pressure is not an issue as condensate drains merely route water that has been condensed on the cooling coils to a drain. The condensate drain is open to the atmosphere at both ends. Only gravity to generate flow when a building drain is located below the cooling coil.  Otherwise, small condensate pumps are used to lift the condensate to the nearest building drain.

Because of the low internal pressure, lightweight copper drainage tube can be used for condensate drainage systems
