ATTSU - Model HH -Industrial Steam Boilers

It's main summed up characteristics are:

• 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.
