What H. Schalm does

Schalm GmbH is a family-owned German Mittelstand technical building equipment (TGA - Technische Gebäudeausrüstung) contractor founded in 1979 and headquartered in Mönchengladbach, with a secondary office in Viersen. The company plans, installs, maintains, and repairs heating, sanitary, ventilation, climate, refrigeration, and insulation systems for industrial clients, large public and commercial construction projects, and private households. Core technical capabilities include CAD-based load calculation and media routing for HVAC and refrigeration systems, F-Gas regulation-compliant refrigeration design, BOB 24/72 industrial steam boiler operation modes (gas/biogas supply without permanent supervision), and DIN-compliant thermal, cold, acoustic, and fire-protection insulation engineering per DIN 18421, DIN 4109, and DIN 18159.

The business operates as a sales-led, project-based service company with direct engagement through phone, email, and website contact channels, supported by a digital presence across social, newsletter, and YouTube properties for top-of-funnel demand generation. Customers are segmented horizontally into industrial clients (manufacturing, chemical, food production, automotive), public-sector and large construction projects (hospitals, fire stations, universities, opera houses, banking facilities, supercomputing data centers), and private households; named enterprise references include Daimler, Lanxess/Chempark, Commerzbank, Krankenhaus Witten, Opernhaus Düsseldorf, Hochschule Mönchengladbach, Supercomputer Jülich (Jupiter), Feuerwache Neuss, Kö-Bogen Düsseldorf, and Lebensmittelproduktionsfabrik Neuss.

Revenue is split between one-time project installation services and recurring service, maintenance, and operations revenue delivered through the wholly-owned subsidiary Schalm Service GmbH, which manages BOB-mode boiler operations, water/condensate systems, and gas/biogas supply maintenance. Distribution is anchored in the HWP Handwerkspartner Gruppe network for cross-trade referrals and complemented by technology brand partnerships with Weishaupt, Viessmann, Buderus, Geberit, Wilo, and DVFLG. Pricing is project-specific and quote-based with no standardized public tiering, and the company operates under four Managing Directors (Armin Schalm, Norbert Schalm, Sultan May, Joachim Onkelbach) across its NRW home market with nationwide and selective Netherlands reach.
