Auto change over unit

Change over module to be mounted in in- or in outlet lines from vaporizers with central outlet. All controls (small PLC, Telemecanique-Zelio) and change over valves are mounted on stainless steel frame. vaporizers are automatically switched over on set temperature by PT100 in gas outlet. The moment vaporiser (bank) 1 reaches the set gas outlet temperature (factory set at -10 ºC), valve in outlet will be closed and vaporiser (bank) 2 will start. To avoid long working periods, vaporizers will be switched periodically (can be set manually on panel at 2,4,6 or 8 hours). A low temperature alarm (potential free contact) on connections terminal is provided for. All the functions, with the exception of the adjustment of the temperature set point and switch-over time, are designed to be automatic without the need for operator input during normal operation.

Advantages:

• Reduces size and number of ambient vaporizers required
• Simplifies field installation
• Centre line can be between 300 - 900 mm to adjust to different designs of vaporizers
• Unit is CE marked leaving only transfer piping in the field
