    ORDER THE EQUIPMENT'S IN EXISTENCE

Gas-fired water-tube boiler for external installation, fully assembled inside of metal insulated block. The boiler equipped with atmospheric burner. The heat exchanger is made of finned tubes with high heat transfer surface.

Type of fuel:

  • Natural gas GOST 5542-87,
  • Liquefied petroleum gas LPG (propane-butane)

The complete set of the boiler for external installation includes:

  • boiler RSA series;
  • instruments (pressure control, water temperature control, gas low pressure control);
  • pipelines and valves.

Additional equipment for water-heating boiler is available optionally:

  • circulation pump, mesh filter (Y-strainer), safety valves;
  • methane gas contamination alarm;
  • thermal shut-off valve;
  • emergency signal transmission system via radio or to the owner's cell phone.
