Abstract
An electronic device is disclosed for controlling gas flow in a gas dryer such as a twin tower regenerative gas dryer. The device has a housing in which is mounted an electronic control circuit. At least two electrically operated valves (e.g. solenoid valves) for controlling functions of the dryer are provided with plugs or sockets and adapted to co-operate with corresponding sockets or plugs in a wall of the housing electrically connected to the electronic circuit. The valves are mounted on, externally of, the housing and are electrically connected to the control circuit.
