What Klima Therm does

Klima-Therm (legal entity Klima Therm Ltd) is a Wimbledon, London-based specialist supplier and integrator of commercial and industrial HVACR systems, operating since 1982 as a subsidiary of the Calibre Services Group alongside sister company LH plc, which provides installation, commissioning, maintenance, and decommissioning services through one of the UK's largest teams of qualified air conditioning and refrigeration engineers. The company supplies ultra-high-efficiency chillers (air-cooled, water-cooled, centrifugal, absorption, and Danfoss Turbocor oil-free), a comprehensive range of air handling units (including HTM/hospital, modular, and MVHR variants), heat pumps (air-to-water, CO2, high-temperature, modular, polyvalent, and propane/R290), air conditioning, fan coils, chilled beams, heat rejection, humidification, and dehumidification equipment. Its technology positioning centres on low-GWP refrigerants (R290 propane, CO2/R744) and high-temperature heat pumps (up to 85°C) that replace gas/oil systems, supporting the UK's F-gas phase-down and public-sector decarbonization agendas.

The business model combines hardware distribution of partner-manufactured equipment (Rhoss, Danfoss Turbocor, Engie, Enerblue, Geoclima, Gree, Fisair, Kiefer, MITA, Saiver) with full-lifecycle professional services delivered via LH plc — specification, installation, commissioning, maintenance, fault-finding, and decommissioning — under bespoke project-based quoting with multi-year maintenance contracts. Klima-Therm sells primarily through direct enterprise field sales into commercial buildings, public sector estates, education, heritage/landmark buildings, data centres, healthcare, and sports/leisure facilities, with named customers including London Stock Exchange, Royal Albert Hall, The Dorchester, Waitrose, Northbrook College, Stewart House (University of London), Kingston College, Grosvenor Estates, and Sketch. Marketing is driven by technical content marketing, CPD programmes for consulting engineers and contractors, industry award participation, and project case studies, with a stated focus on Great Britain and particular strength in London and major urban centres.
