Heat exchange module for hot water

The heat exchange module MAFAC HEAT.X provides an alternative to electrical heating of cleaning agents: the utilization of the available external heat. The module works with a highly efficient heat exchange process. The available heating agent flows through a coaxial heat exchanger, while the cleaning agent which needs to be heated is fed to the same heat exchanger but runs through a separate pipe. In counterflow principle, the heating agent warms up the cleaning agent by means of direct heat transmission. The cleaning agent is then returned to the cleaning process.

In this way, electricity for heating may be replaced by alternative energy sources:

  • use of waste/industrial water following heat treatment (e.g. in foundries)
  • from cogeneration
  • regenerative water heating applications (solar heat)

The heat exchange module can also be operated in mixed operation with electricity and water and can be connected to a wide range of machines, not only to MAFAC parts washers. Whether you are preparing for the purchase of a new machine or the execution of a major project, our project planning department will be glad to develop an individual solution.

How will you benefit from using a heat exchange module?

  • Potential reduction of the power consumption for bath heating of max. 60%
  • Electricity tax refund if you implement energy management systems (DIN EN ISO 50001) and/or environmental management systems (DIN EN ISO 14001)
  • Reduction of CO2 emissions (617 g CO2/kWhEnd according to GEMIS power mix Germany).
  • Potential reduction of the connected load of the machine of up to 50% (if heated only with water)
  • Fast availability of technical heat thanks to the highly integrated power density in the heat exchanger
  • No waste of existing heat because sources of warm production water are used
