SPH Sustainable Process Heat – your partner for green process heat

Recycle heat – save energy costs and reduce your CO2 emissions

Higher temperatures

Hotter and more efficient than other heat pumps

The global demand for industrial process heat between 100°C and 200°C is 6,500 TWh per year and is expected to increase by 20% by 2030. Currently, more than 80% of this heat is generated by burning fossil fuels, emitting millions of tons of CO2 into the atmosphere.

In the past, industrial heat pumps were limited to initial temperatures below 100°C, whereas a large part of the process heat demand requires temperatures of 100°C-200°C. SPH Sustainable Process Heat GmbH is now changing this with its range of high temperature heat pumps for industrial process heat. The heat pumps are currently capable of generating temperatures of up to 165°C and in the future of over 200°C. This is made possible by a specially developed high-temperature piston compressor in combination with innovative process technology.

The current process

Fossil fuels are burned, the residual heat is simply expelled or cooled away

The SPH way

We use previously unused low-temperature waste heat and convert it into high-quality process heat with our systems

For a greener world

If the plant is operated with green electricity, it produces:

No CO₂
