Built for Industry
Low-cost clean heat. Seamless integration. No compromise
Heatcube is made to decarbonize industries with process heat needs in the 150–300°C range.
By integrating directly with existing steam infrastructure, Heatcube replaces fossil-fired boilers, supplying low-cost heat and enabling a clean energy switch without disrupting operations.
Industries we supply

Food & Beverage
Cooking, preheating, washing and pasteurization are the main areas for heat demand. A big share of energy is also used for refrigeration.

Pharmaceuticals
From sterilization to temperature-controlled logistics, the industry is built on energy-intensive processes that rely heavily on fossil fuels.

Paper, pulp and print
Heat is used to dry the pulp and heat the calendar rolls. It is also needed for recycled newsprint, specialty papers and packaging.

Chemical and petrochemical
Most of the heat is used for ammonia production by steam reforming of natural gas, steam cracking of naphtha and steam cracking of gas oil.

Iron and steel
Steel production requires very high temperatures to heat and melt iron ore. We can save a lot of energy by pre-heating the production parts.

Non-ferrous metals
Heat is used almost entirely in specific electrical processes. It is required mostly in the aluminum, copper and zinc production.
