HTH

What HTH does

HTH Gruppe is a German technical wholesale distributor specializing in ventilation and air-conditioning technology, founded in 1998 and headquartered in Langenhagen near Hannover. The company operates 9 owner-managed locations across Germany with 4 production sites (Hannover, Hamburg, Dresden, and Allgäu) where it manufactures air-handling components — including spiral ducts (Wickelfalzrohre) and VDI 6022-certified canvas duct connectors — across all material categories. Its combined warehouse footprint exceeds 12,000 m² and holds more than 10,000 pocket filters, enabling stock-holding and rapid delivery to construction sites nationwide through a cross-location ERP system. The product portfolio spans 8+ categories: fans, fire protection technology (including TROX dampers), filtration, air diffusers, gastronomy/kitchen ventilation, ventilation units (including Airflow DUPLEXbase PS), acoustic/thermal insulation, and MSR (measurement, control, regulation) technology.

HTH's customer base consists primarily of tradespeople, craftsmen, and engineering planning offices in the German HVAC sector — SMB customers requiring technically qualified consultation, project sizing support, and reliable stock availability. Go-to-market is sales-led, combining direct field sales representatives at each branch, an inside sales team, and a self-service e-commerce shop (hth24.de). The company distributes on behalf of more than 30 brand partners (TROX, Belimo, Helios, LG, Airflow, Maico, Isover, Hekatron, etc.) and supplements the portfolio with proprietary digital sizing tools (HTH-Akustikx, Filterzellenkonfigurator, Luftfilter Matrix) and an annual customer training calendar. Revenue is generated through one-time product sales at trade list prices, with periodic surcharges (Teuerungszuschläge) reflecting raw-material and energy market conditions.

HTH is family-owned under sole shareholder Mark Hesseldieck, with a holding structure (HTH Holding GmbH & Co. KG) and a generational succession underway — son Jonas Hesseldieck joined management in December 2023. The group has executed inorganic expansion in southern Germany, opening HTH Landshut in October 2023 and acquiring Lacuna Air Produktions- und Handels GmbH's trading and production business in April 2025 to form HTH Allgäu. Operations are led by Co-Managing Director Benjamin Borgfeld. Revenue is not publicly disclosed.
