The HCU-ER HCU100 series extracts gas from the chamber into the active scrubber, injecting additional moisture to improve scrubbing capacity. The gas passes through the chemical absorbent which retains any CO₂ present in the gas.

Gas is then transferred to the dehumidifier where it passes over a cold water coil. This coil has the effect of lowering the gas to a temperature below its dew point; reducing relative humidity and enabling the collection of condensation in the dehumidifier sump.

The 3-stage blower then accelerates the gas into the heater where a hot water coil increases the gas temperature. The fully reconditioned gas is then circulated back into the chamber.

Local control via HMI allows the operator to view at a glance chamber temperature, humidity, blower speed and alarms; as well as establish set points for these criteria and run system tests. Essential to the operation of the HCU-ER is the supply of 440VAC, 3~, 60Hz, which is transformed and rectified to 24VDC by the integral HCU transformer.
