The RA2 duct is fabricated from clear acrylic for visibility and mounted on a painted steel frame.
Air is drawn into the duct by a variable-speed fan, and is passed through a flow straightener to the preheat heating elements. The air is then passed over a nozzle from a steam boiler, which allows the air to be humidified.
The next component in the duct is the evaporator of the integral refrigeration unit. As the air passes through the evaporator it is cooled down. The evaporator housing also allows any water which condenses from the air to be collected in an external vessel.
After the evaporator the air passes over the reheat elements and out through a louvered exit.
Temperature and RH sensors are provided at the air inlet, after the preheat and humidifier, after the evaporator and after the reheat. The air flow is measured by an electronic sensor. The mains supply voltage is monitored in the equipment to allow calculation of effective heater powers
Underneath the duct are mounted the steam boiler for the humidifier, the compressor and condenser for the refrigeration system and the electronic control box.
