Detail
The D-BS4-T is an automatic surface blowdown system for steam boilers based on conductivity measurement. It uses a conductivity probe that works in conjunction with a controller to operate the motorized valve when the set conductivity threshold is exceeded. Operating at 24VDC, the system ensures energy and chemical savings while enhancing boiler safety. Fully compliant with EN 12953.
