Industrial cooling and heating.

Partner of the industry for over 40 years.

Since 1971 DELTATHERM® has belonged to Hirmer GmbH, a family business with its headquarters in Much near Cologne, one of the leading German manufacturers of cooling and heating systems. In three plants, 120 employees produce and distribute about 10,000 chillers, temperature control units, heating and cooling equipment and cooling components per year. All plants are located in the greater Cologne area. DELTATHERM® has a plant of its own for manufacturing casings and cabinets. We also have our own software development and build our own control electronics. Working closely together with our customers, our engineers are happy to develop special solutions and individual designs. 120 service partners support our plant customer service in 60 countries on 6 continents. We always have 95 % of all replacement parts in stock, ready for dispatch within 24 hours. Quality, process safety, ease of maintenance and user-friendliness are our top priorities.

The safety of your production plants and of the production process are, to a large extent, dependent upon how well and how reliably your processes are temperature- controlled or cooled. At DELTATHERM®, qualified specialists - from trained tradespeople to master craftsmen and engineers - ensure the optimal mixture of planning, project engineering, diligent manufacturing methods and thorough quality control. Our planning and construction department, the building of our own control electronics and software development as well as our own plant for metal working all ensure that we have almost the entire vertical range of manufacture for temperature control units in-house. Purchased components such as pumps, valves, relays etc. are acquired from market-leading or renowned manufacturers.

All devices and systems are subject to a comprehensive functional test before dispatch. Because we are fully aware of what a plant standstill and the resulting production downtimes can cost our customers, we offer:

  • Global plant service
  • Service hotline to our experts, in German and English.
  • All standard components in stock and available globally in the shortest time by express mail.
  • Replacement part availability >95%
  • More than 120 service partners with locations on 6 continents – in Europe, North America, South America, Africa, Asia and Australia
  • 24-hour online service, through which we can check and maintain your systems
  • Ensuring the productivity of your DELTATHERM® machines 

"We focus on only one thing: customer satisfaction. We achieve satisfaction through our high product quality, 24-hour service and the highest level of exi- bility, through which we nd individual solutions for all requirements. And we live out this claim - every day, for 40 years."
