Due to its large volume and steam chamber height, together with the addition of the drip trap, the HH boiler is one of the biggest selling boilers.
Thanks to the design and smoke tube section as well as the separation between the tubes, the H 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 H 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 H boiler has a low thermal load in the combustion chamber (less than 1.25 MW/m3) thus achieving combustion that pollutes very little.
The H boiler is one of the highest performing boilers on the market: according to the pressure and fuel, it can reach 91%.
Energy savings can reach up to 6% by installing an ATTSU economizer, for heating feed water.
The H 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 boiler platform protects it from possible damage.
The upper boiler ladder and platform are protective measures for maintenance staff that are supplied as an option upon request.
The H boiler, thanks to the single setup control, incidence indicators, automatic blocking against erroneous maneuvers and a panel with summarized maintenance instructions makes it very reliable and comprehensible to the boiler operator.
It provides a low heat loss from radiation thanks to the insulation of great thickness as well as front and back door insulation. Thermal insulation is composed by a thick layer of low conductivity and high density material, covered by a stainless steel metallic enclosure.
The boiler could be optionally equipped with PLC including different communication protocols such as Modbus, Profibus, etc., enabling boiler integration in any industrial process.
The H boiler is certified in accordance with European Directive 2014/68/UE.and optionally could be certified according to ASME, BS, DNV, EAC, DOSH, JIS and others.
