Superheated water boiler HHAS series

Thanks to the design and smoke tube section as well as the separation between the tubes, the HHAS boiler has good internal water recirculation. This ensures greater heat transfer and achieves low resistance to smoke passage. •As a consequence of ongoing research and the experience accumulated over more than 75 years, the HHAS boiler thanks to its insulation of great thickness and high density, as well as its insulated door design has very little loss from radiation. •The furnace design is such that the HHAS boiler has a low thermal load in the combustion chamber (less than 1.25 MW/m3) thus achieving combustion that pollutes very little. •The HHAS boiler is one of the highest performing boilers on the market: according to the pressure and fuel, it can reach 91%. •The HHAS boiler may be supplied (upon request) with the ATTSUTROL electric control cabinet, with built in automation. Twenty-four or seventy-two hour surveillance may be achieved. •The plastic protector coating the external insulation (reflective polished stainless steel), preserves it during the installation process. Furthermore, the upper generator platform protects it from possible damage.
