Working together, the boilermaker and the GESTRA team designed a solution that integrated the necessary boiler controls and level limiters to create a full open feedwater system that would keep a consistent water flow to the boiler in all instances.  The choice of product would allow additional switch-over MIN/MAX relays that could control the feedwater system so that there would be no need to stop the boiler when servicing the control valves.

GESTRA's technical solution included the following products:


Level limiter SPECTORmodul – NRG16-50, NRS1-50

Pneumatic control valves
