Heat pumps technologies in industrial drying processes


HP4D technology is a heating & drying system based on heat pumps, own ideas use dedicated thermodynamic modules for maintaining hot and closed air cycle, that provides thermal energy essential for drying processes. This is currently the only highly effective technology in the world, enabling reduction of energy usage 4 to 7 times.

The majority of drying plants, that use hot air for drying purposes, can be integrated with that technology. HP4D – Drying Process provide solutions for the drying plants currently being designed as well as for the existing ones. Implementing HP4D technologies is based on substituting a classical heating system, like gas burners, oil, coal or electrical boilers together with their heat exchangers.

Replacing the classical heating system with heat pumps results in 2 to 4 times lower drying costs, CO2 emission reduction, possibility to use recovered water in other industrial applications and makes the whole drying process independent of variable environmental conditions. High energy efficiency can lead to the possibility of acquiring higher grants coming from White Certificates and government subventions for research and development. you can find more information in the “Technology Description” tab.
