PREXTHERM T3G N

• Boiler body made entirely from steel, completely lined with a layer of high-density mineral wool, protected by stainless steel plate, meaning very low heat loss to the surrounding environment.

• Energy efficiency exceeding 92%.

• Maximum design pressure 6 bars, higher pressure on request.

• Combustion chamber consisting of a large furnace reinforced with omega joints to guarantee operation at low heating loads.

• Tube bundle on the second and third flue gas pass, with high heat exchange surface.

• Large inspection doors both on the front, for flue gas reversal from the second to third pass, and at the rear for the smokebox.

• Rear manhole for inspecting the furnace.

• Supplied in two parts, steel body complete with casing, and satellite controls.

• The water circuit can be inspected through a manhole at the top of the boiler and a hand opening ring at the bottom.

• Rear smokebox completely lined with high density mineral wool insulation.

• Thermostatic control panel. Thermostatic controller for single-stage or two-stage burners, with the possibility to control the system pump.
