Our Services

The GSX range includes three pass wet back firetube steam boilers. Designed with cutting-edge technology and manufactured to meet specific design needs in terms of polluting emissions.

Upon request, they can be provided with Intergral energy saving economisers integrated into the boiler structure in order to maximise the efficiency without heat losses. The integral casing can be removed in those areas containing parts that require inspections.


Design pressure: 12 or 15 bar
Nominal power: 238 ÷ 4088 kW
Steam production: 350 to 6000 kg / h
Efficiency: > 90%

Upon request, it is possible to have a maximum design pressure  of 25 bar – maximum steam production 6000 kg/h



High steam quality

At high load, the internal separator prevents the entrainment of water droplets to the steam outlet, the steam produced is then always of high quality having a very high dryness fraction.

Advanced management technology

The boiler can be equipped with programmable logic technology that allows complete compatibility with any data acquisition system, also allowing the adjustment of parameters through the display.

Reliability and durability

Maximum reliability and durability guaranteed through design with low surface heat losses.

Consistent supply of high-quality steam

Thanks to the generously dimensioned steam chamber the boiler can meet the varying demand of the system including instantaneous peak demands

Efficiency at all costs

Integrated solutions for increased performance and efficiency through flue gas heat recovery fully integrated into the structure of the boiler.

High efficiency and large exchange surfaces

Extremely high energy efficiency thanks to the large exchange surfaces allowing top efficiency values under all operating conditions.
