Holtzheim - Cooltech Applications

Company Overview


Making Magnetic Refrigeration the new standard

Cooltech Applications was founded in 2003 with the mission to make Magnetic Refrigeration the new standard in the cooling industry by productizing and commercializing refrigeration systems based on magnetic cooling.

After more than 10 years of intensive and in-depth research in diverse technological fields as magnetism, hydraulics, thermal mechanics and chemistry, Cooltech Applications has developed a unique cleantech solution, based on the 19th century discovery of magnetocaloric effect. The solution replaces existing compressors using refrigerant gases with a compression-less, gas-free, energy efficient, and environment friendly appliance.

Cooltech Applications is the first company in the world to commercialize Magnetic Refrigeration Products. The first Magnetic Refrigeration System introduced by Cooltech Applications primarily addresses the commercial refrigeration market (plug-in display cases for stores, kitchen equipment, beverage coolers, medical refrigerators...).

Cooltech Applications has also engaged with customers on applying the magnetic cooling approach to other market segments through co-development partnerships (e.g. Domestic refrigeration, Industrial cooling...).

Cooltech contributes to collaborative research and development programs with major industrial groups:

  • FP7 ICE - Heating and air conditioning for electrical collective transports
  • MagFreeG - Deployment for commercial refrigeration applications (EU’s Eco-innovation project)
  • MagCop - Research, development and industrial production ecosystem for Cooltech Applications’ products
  • MagCool - Magnetocaloric materials
  • Zen E-Drive - Light electric vehicle with solar charging stations
  • IFPEN - Thermal exchanger for magnetocaloric systems

Based in the outskirt of Strasbourg, Cooltech Applications is backed by well-established investors.
