Klingenburg UK

What Klingenburg UK does

Klingenburg UK (legal entity Klingenburg U.K. Ltd) is the United Kingdom sales, consulting, and service subsidiary of Klingenburg GmbH, a German-engineered manufacturer of energy recovery and climate control equipment founded in 1979 and headquartered in Gladbeck, Germany. Operating from a 7-person office in Folkestone, Kent, the UK entity serves as the regional channel for the group's rotary heat exchangers, cross-flow plate heat exchangers, sorption rotors (including the proprietary DekaTru® zeolite-coated HUgo rotor), CERTO high-pressure humidifiers, DEC (Dessicative Evaporative Cooling) systems, and warm air heating products from the Apen range (LK, LRP, AX). The underlying technology centres on heat and moisture transfer between supply and exhaust air streams, with nanometre-scale zeolite coatings enabling both sensible and latent heat recovery for HVAC, paint shop, data centre, and large commercial building applications.

Klingenburg UK generates revenue through one-time equipment sales (heat exchangers, humidifiers, heating modules) complemented by professional service revenue from technical consulting, commissioning, preventive maintenance, repairs, modernisation, and service contracts. Go-to-market is enterprise field sales with individual system planning and custom design for each installation, delivered through a small named team (Country Manager, Sales Technical & Service, Service Manager). Customer segments span HVAC contractors and building systems integrators (primary), automotive paint shops, data centre operators, and large commercial building owners (auditoriums, offices, hotels, printing works). Distribution is direct with regional offices across Germany, UK, Poland, Spain, and the USA. Following CAREL Industries' 2023 acquisition of 100% of the share capital of Klingenburg GmbH, the UK entity sits within a larger HVAC controls group, expanding cross-sell potential but with limited public disclosure of standalone revenue or growth metrics.
