L & R Kältetechnik GmbH & Co.KG

We stand for energy-efficient refrigeration technology with a focus on the environmentally-friendly and energy-conscious use of high-performance, high-quality refrigeration systems.

 In close cooperation with you, the user, we develop comprehensive concepts to support your success. Our range of services includes: cooling and temperature control systems in various design and performance variants, as well as system commissioning, system inspection, and the optimisation of existing systems. Our temperature spectrum ranges from -120°C to +350°C.

A very special core competency lies in our in-house control cabinet construction. Because only in this way are we able to adapt your system perfectly to your needs. We are also happy to offer this as a service for companies in the mechanical and plant engineering sector.


We have been successful on the market since 1991 and are constantly developing. An idea has become a globally active company. We enjoy shaping the future with our ideas. For instance, we have developed the "Frigo-Control" system, as well as the "VariKon" variable condensing temperature control system, and the contact cooling of pharmaceutical substances through our plate freezer, or the EcoPro series, which today represents our new standard for industrial refrigeration systems.

 We look forward to the future!
