BUVA 150/EM water treatment appliance

Intended for: Boiler rooms
Order No.: 72007

The BUVA 150/EM water treatment appliance is a complete appliance for water treatment, designed for filling and adding water into closed hot-water heating systems and boiler rooms. The design and technology make it suitable for boiler rooms with a total output of up to 500 kW. In compliance with CSN 07 7401, it allows water softening using an automatic softening filter, and treating water by manually adding inhibitors of corrosion, using a dispensing container.

The advantage of BUVA lies in the easy and trouble-free installation on the installation site; the installation firm only connects at the water inlet and outlet using G3/4” fitting. Operating technological water treatment components are installed on a frame welded from steel sections; they are functionally connected, and pressure tested.

Integrated technological components of the water treatment plant:

  • automatic AZ softening filter
  • salt container for dissolving regeneration salt
  • dispensing container for corrosion inhibitors
  • a system of bypass valves
  • water gauge for measuring the quantity of flowing water
  • pressure gauge for measuring output pressure at AZ
  • direct fitting with G3/4" inner thread

The automatic softening filter is equipped with a control valve with electronic volume control.

Such treatment plants are able to deliver about 1-2 m3 of softened water between regeneration cycles.
