What KKT Chillers does

KKT Chillers is a brand of ait-deutschland GmbH, a privately held German manufacturer of industrial and medical process chillers and heat pumps headquartered in Kasendorf, Germany. Founded in 1978 as KKT Kraus and operated within Sweden's NIBE Group since 2011, the company designs, manufactures, and services cooling and combined heating/cooling systems with cooling capacities from approximately 1.7 kW (Nano Line) to 971 kW (Evo Line plus), plus heat pumps up to 1,000 kW (MAGMA). Its product architecture spans a portfolio of modular series (Green Line on natural R290, Compact Line, Vario Line, Evo Line, Evo Line eco on R32, Evo Line plus on low-GWP R454B), medical chillers for MRI/CT/X-Ray imaging (ECO Chiller, cBoxX, System Separator), OEM-embedded solutions via a Resident Engineering program, and the Thermodynamixx suite (MAGMA heat pumps, ARCTIC chillers, Energy Saving System, Water Management System) that recover waste heat for simultaneous heating and cooling. Proprietary components include the Chilltronic II control system, microchannel heat-exchanger technology, EC-Blue-Owlet fans, and the nBoxX programmable controller.

The business model combines custom-engineered hardware sales to medical device OEMs and industrial manufacturers with a directly delivered after-sales service portfolio (ChillStart commissioning, ChillCare maintenance, ChillLearn training, ChillParts spare parts, ChillTune optimization, 24/7 support) and a subscription-style remote-monitoring layer based on LTE-M connectivity and the myUplink cloud. Distribution is direct enterprise field sales with regional sales managers in Germany, the USA, and China, supported by an online Chiller Configurator (COOL SELECTOR) for lead qualification. Pricing is quote-based and not publicly disclosed, reflecting the engineered-to-order nature of the products.

The company's served customer base spans Medical/Healthcare (Siemens Healthineers for MRI magnets and helium compressors, California MRI facility deployments, pharmaceutical manufacturers including Biochrom), Food and Packaging (Krones, Uhlmann, Saudi and Algerian PET bottling plants, Brazilian breweries), Laser Technology and Additive Manufacturing (Amada, Renishaw, automotive laser welding and airbag perforation customers, aerospace laser melting), Plastics and Intralogistics (SSI Schäfer), and Surface Technology. KKT's equipment operates in extreme ambient conditions from Siberia to tropical Vietnam and Oman, with a 30+ country service footprint anchored by owned service locations and global certifications (ISO 9001, ISO 14001, CE, ETL, EAC, GB/CCC, RoHS, REACH, ChemKlimaSchutzV, QSK, OSHPD seismic approval). Leadership rests with three Managing Directors of ait-deutschland GmbH (Heiko Folgmann, Marco Roßmerkel, Sjacco van de Sande); financial ownership and consolidated revenue sit within the publicly listed NIBE Group and are not separately disclosed for the KKT brand.
