Abstract
A method and apparatus for blowing down a compressed air system when temperature is at or below a predefined temperature threshold is provided. Temperature sensors in the compressed air system monitor temperature and a control processor determines when the temperature is at or below the predefined temperature threshold. When it is determined temperature is at or below the predefined temperature threshold, the control processor operates a solenoid blow-down valve that depressurizes the compressed air system.
