PREXTHERM RSH N 100÷1480

• Boiler body made entirely from steel, completely lined with an 80 mm layer of high density glass wool, in turn covered by a strong layer of tearproof material.

• Design pressure 6 bars, (÷10 bars on request)

• Pressurised combustion chamber, completely cooled and protected by a system ensuring uniform division of the cold system return water, to avoid dangerous temperature differences. The burner is not aligned with the combustion chamber but rather has been moved downwards.This assists flame reversal, reduces the flue gas pressure drop and consequently extends the hot water generator’s range of application.

• Tube bundle placed above the furnace so as to guarantee the flue gas passes through a hot section of the hot water generator and consequently reduce the possibility of  condensate forming.

• Turbulators featuring a new design able to increase heat exchange, without affecting pressure drop in the boiler.

• Front door with reversible opening(right and left) and innovative closing system with micrometric adjustment on the hot water generator front plate. Up to model 500 the door is insulated with double lining, made up of one layer of fibre and one layer of Carbowool, while higher output models use a double layer of refractory concrete and insulation.

• Threaded central heating flow outlet and return inlet connections up to model 250 and flanged PN16 for the remaining models.

• Supplied in three parts steel body, casing and satellite controls (satellite to be ordered separately
