• Standard design pressure: 12 bar version ; 14.8 bar version.

• Modern in design and high efficiency, these generators are designed and manufactured in compliance with the European Directive 2014/68/EU (PED) and the most recent national and European standards regarding pressure vessels.

• The full penetration plate/shell weld and the fire tubes are first brought together by means of rolling and then welded to the tube plate.

• The fireplace is generously sized in diameter and length to allow for a low thermal load.

• PREX N ASH generators are equipped with stainless steel turbulators positioned inside the smoke tubes which prevent the formation of a stationary boundary layer on their surface, consequently improving heat exchange.

• Thanks to adequate insulation of the boiler body carried out with a layer of high-density mineral wool, protected by stainless steel sheet, dispersion towards the environment is very limited.

• The front door is made of an adequate thickness of refractory concrete which covers the entire extension of the heated surface of the tube plate. The reversible opening (right or left), and the

The micrometric closing and adjustment system make the tailgate easy to move.

• The welding of the pressurized parts is all carried out by qualified personnel approved according to EN standards.

• Inspection on the water side is guaranteed by a manhole on the top of the boiler and a handhole on the lower part.

• Maintenance guaranteed by the ease of access from the door to the firebox and the tube bundle and by the removable smoke box.
