Since 1971, DELTATHERM® Hirmer GmbH, a family business with its headquarters in Much near Cologne, has been among the leading German producers of industrial cooling and temperature control systems. Our strengths are innovative solutions in countless national and international industrial sectors. DELTATHERM®’s know-how has developed over nearly 40 years – we are distinguished by our experience in planning, producing, operating and supervising industrial cooling and temperature control systems.

We see ourselves as a one-stop systems provider who delivers everything from design and planning to sales, implementation and service. Thanks to our central, customer-oriented corporate structure, we are flexible, fast, high-performing and always available on-site. If you have questions about custom-designed cooling or temperature control solutions, our product engineers are all ears and ready with an optimal solution. Our extremely high in-house production depth allows us to be largely independent of suppliers, meaning that we carry out every order in best quality and on time.

In particular for engineering purposes, DELTATHERM® offers standard and system-dependent cooling units and system solutions for various cooling needs which demonstrate their capacity every day all around the clock in extreme climatic conditions, for instance in Southeast Asia, and in uncompromising high performance operations. For these tasks, differing voltages and frequencies are available for the world-wide application of our cooling and temperature control systems. This, along with certification according to DIN EN ISO 9001 : 2008 as well as compliance with relevant standards and specifications such as EN 378, EN 60204, UVV and VBG, guarantees universally high quality.
