DELTATHERM®: Industrial cooling and temperature control systems - Partner of the industry for more than 50 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 temperature control systems.

We manufacture standard and plant-specific cooling units and system solutions for a wide range of cooling requirements. For high precision, temperature stability (up to +/-0.02 K) and continuous operation in process cooling.
In the wide range of applications in metalworking, for example, main and counter-spindle motors, torque motors, linear drives, machine beds, electrical control cabinets and the workpieces to be machined are cooled in machine tool manufacturing. Water, oil, emulsions and other cooling liquids are used as cooling media.
Cooling lubricants, which are contaminated by chips and dust, are required for almost every type of metal-cutting operation. The emulsions and oils in coolant filtration systems are kept at a precise temperature and cooled with our immersion coolers or industrial once-through coolers.

DELTATHERM® cooling systems are used internationally in a wide variety of industrial sectors:
Laser technology. Filtration. Welding & cutting. Turning & Milling. Plastics. Chemical and food industry. etc.

We manufacture chillers, heat exchanger systems, temperature control units, heaters as well as cooling systems and cooling components.

More than 200 cooling systems: standard units and special designs - from single units to series.

- Cooling capacities from 0.2 W to 15,000 kW
- Ambient temperatures from - 35 °C to + 60 °C
- Coolant temperatures from -80 °C to + 300 °C

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.
Thanks to an in-house planning and design department, software development, control system construction, including an on-premises paint shop, we cover almost the entire vertical range of manufacture for cooling and temperature control units.
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.
An expanding worldwide network of service partners supports our factory customer service in 60 countries on six 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.

We will be happy to help you find the system that is optimally designed for your process.
