TestEquity 115A-EX Temperature Chamber
Condensate Drain
The condensate drain connection is located on the rear of the chamber. This provides a way to
remove condensate that may accumulate on the evaporator (cooling coil) during temperature
cycling or when the refrigeration system runs to maintain moderate temperatures.
Any time the ambient air is subjected to temperatures below the dew point, moisture will
condense out of the air. The effect is ice or frost during low temperature operation. When the
chamber is heated above 0°C or the cooling system turns off, the ice or frost will turn into water.
The drain fitting accommodates a 1/4-inch male pipe thread. The chamber drain water is not
under pressure and is fed by gravity. Therefore, it must empty into a container or open floor
drain. Alternatively, the chamber drain can empty into a condensate pump. You can purchase a
condensate pump from an industrial supplier.
Under most circumstances, you will not see any water coming out of the drain.
