What L&R Kaltetechnik does
L&R Kältetechnik GmbH & Co. KG is a family-owned German manufacturer of custom industrial refrigeration and cooling systems, headquartered in Sundern, Sauerland, and founded in 1991. The company designs, engineers, manufactures, and installs bespoke refrigeration plants for industrial customers, with a portfolio spanning industrial chillers (including the ECOPRO 2.0 series), low-temperature technology down to -70°C, cooling towers, containerized refrigeration systems, compact and split chillers, water treatment systems, and a proprietary FRIGOCONTROL regulation system used alongside Siemens S7 controls. Notable technical components include VariKon variable condensing temperature control, free cooling/winter relief, heat recovery, and adoption of low-GWP refrigerants (R513A HFO blend) and natural refrigerants (R290 propane) positioned ahead of European F-Gas regulation.
The company operates a project-based B2B enterprise sales model, selling directly to manufacturing customers in plastics and rubber processing (Möller Flex, Sealed Air, Spies Kunststoffe), surface treatment and electroplating (WHW Hillebrand), metalworking and precision machining (Franz Funke Zerspanungstechnik), and automotive suppliers (including an anonymized Sauerland supplier serving Daimler, BMW, Audi). Pricing is quote-based with transparent payback analysis on energy-saving measures. Revenue streams comprise custom hardware sales (primary), aftermarket services (24/7 COOL-LINE hotline, remote teleservice, maintenance), and rental equipment delivered through a 2019 strategic partnership with SOS Rental GmbH. The company claims worldwide reach from its DACH-region base, holds EN ISO 3834-3 welding certification from TÜV Süd, and was recognized as a TOP 100 German Innovator in 2024.
