PREXTHERM T3G F ASL

• Standard design pressure 6 bars or 8 bars

• 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.

• The front door consists of an adequate thickness of refractory cement that covers the entire heated surface of the pipe plates. The front door with reversible opening (right and left), and the micrometric  losing and adjustment system make the door easy to move.

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

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

• Maintenance guaranteed by easy access to the furnace and the tube bundle through the door, the removable smokebox and the inspection door on the boiler body.
