PREXTHERM T3G N ASL

• Standard design pressure: 6 or 8 bar.

• These modern-concept and high-efficiency generators have been designed and developed in compliance with European Directive 2014/68/UE (PED) and the most recent national and European standards on pressurised recipients.

• Combustion chamber consisting of a large furnace reinforced with omega joints to guarantee operation at low heating loads, with completely water-cooled reversing chamber.

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

• Suitable insulation of the boiler body using highdensity mineral wool protected by stainless steel plate limits heat loss to the surrounding environment. 79

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

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

• Rear manhole for inspecting the furnace.

• The parts subject to pressure are all welded by qualified and IIS approved personnel, according to EN standards.

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