Steam Boilers

Ici Caldaie have a proud 60 year history and the largest production plant for steel and industrial boilers in Europe, producing around 12,000 hot water boilers and 1000 industrial boilers per year. They are also a leader in the journey towards new forms of energy generation and cleaner technologies, with many collaborative projects working simultaneously on both sustainability and green energy, mostly linked to hydrogen as a fuel source.

They have a complete range of high efficiency steam boilers and indirect steam generators utilising the latest European designs for high efficiency and low emissions.

Supplied fully packaged and ready for installation, these boilers feature advanced energy saving controls:

  • Fully modulating burner control

  • Auto TDS control

  • Exhaust heat recovery options

  • Multi-stage variable speed feedwater control

  • Automated blowdown control

The above form part of a Global Safety System for boiler operation without supervision (unattended operation) for up 72 hours of continuous boiler operation.

The boilers are designed, manufactured and fully tested prior to delivery to a range of international standards including European Directive 2014/68/EU (PED), ASME, Lloyds Register, Rina, & TUV. They also meet, in full, the NZ standard requirements, namely the “Health and Safety in Employment Act 1992 – Approved Code of Practice for the Design, Safe Operation, Maintenance, and Servicing of Boilers” and the AS/NZS 3000 Electrical Wiring Rules.


Range of compact steam boilers from 50-300kg/h for medium pressure (<5bar) applications.
The latest generation low-emission, high efficiency, fully autonomous, high pressure steam boilers from 350kg/h to 3000kg/h.
Both low and high pressure, high efficiency steam boilers from 100 to 25,000kg/h with high thermal capacity for demanding applications.
Fully packaged indirect generators of clean steam for hospitals, sterilization processes, and the food & beverage industry.
