The drain back system rig is assembled on a mobile frame similar to the Evacuated Tube Direct Flow Solar Rig.
The conventional flat plate collector system simulates the basic solar installation that allows the heat transfer fluid
to be drained from the collector at sub zero temperatures. This system is widely used in Mediterranean areas.
The Training Rig includes a flow setter, circulating pump, an 8 Litre Drain Back tank and sensors positioned in the solar
collector and the cylinder. It is designed to be moved through standard doorways. It has robust, lockable wheels.
