Discover our unique development & manufacturing process

We‘re there for every step of your journey to achieve the best cooling solution for your requirement – From concept, through development, simulation and prototyping, to series production and delivery.

Discover our unique development & manufacturing process We‘re there for every step of your journey to achieve the best cooling solution for your requirement – From concept, through development, simulation and prototyping, to series production and delivery. Start
The basis for all projects: A detailed concept Good planning pays off. During our concept phase we're working closely with you to fully understand all details of your requirements. This leads us to a thought-out concept. Concept
Detailed development for a optimal cooling component What differentiates us from other vendors is the dedicated development phase. After setting the stage for a successful project during the concept, we now begin developing your individual cooling solution to fulfill your requirements. Development
Simulating your new cooling solution By request, we'll test and simulate your new cooling parts and cold plates for their thermal characteristics and efficiency using newest simulation tools. This allows us to keep the production sustained and on resources. Simulation
Your cooling component as physical prototype Physical prototypes are the essential foundation for series production of efficient cooling solutions. During this phase we build the cooling component for your testing purposes or client approval. Prototyping
Streamlined production for batches of every size Because of our standardized and lean production processes, we're able to produce any amount of your individual cooling parts up to mass production. Always at highest quality. Production
Highest quality and precision. Made in Germany We're certified. No unit leaves our facilities without scrutiny by a dedicated pair of eyes and highly accurate machine testing. Quality Testing
Fast delivery to your preferred destination Let us know exactly when and where you need individual cooling parts. We'll have them there on time and on budget. We can build a supply chain for you, too. Delivery

Standardized processes for individual cooling solutions

We build individual cooling solutions with precision and perfection using state-of-the-art production methods, at highly competitive prices.

With more than 20 years' experience in cooling technology and a large number of successful projects, we are trusted by companies worldwide like GE Energy, Siemens, Otis, Oerlikon and Pentair for outstanding reliability, razor-sharp precision, and high quality.
