Polzenith

What Polzenith does

Polzenith GmbH & Co. KG is a German family-owned industrial machinery manufacturer founded in 1963 by Gregor Pollmeier and currently under second-generation family management. Headquartered in Schloß Holte-Stukenbrock, North Rhine-Westphalia, the company specializes in designing, manufacturing, and servicing biomass energy systems for industrial process-heat applications. Its product portfolio spans heating boilers (Heizkessel) in multiple configurations (HO/SP/II TWIN, HO/SP/II, HO/R/II, HO/R/ST), containerized energy systems (Energiecontainer) for modular deployment and rapid boiler replacement, discharge and extraction systems (Austragssysteme), biomass conveying equipment (Fördereinrichtungen), steel chimneys (Stahlkamine), and dust extraction systems (Entstaubungsanlagen). Underlying technology centers on combustion-based biomass heat generation with full in-house mechanical engineering and fabrication.

The business operates an enterprise field-sales model targeting mid-market industrial manufacturers in Germany, with custom-specified equipment, on-site installation, and recurring maintenance service. Revenue is generated primarily through one-time capital-equipment sales (priced per project with a 1/3 deposit on order and 2/3 on delivery per the AGB) supplemented by professional field-service and maintenance revenue. Pricing is not publicly disclosed. Customer verticals include sawmills and lumber processors (e.g., Sägewerk Karl Streit, Sägewerk Ernst Fisch), galvanizing and metal-finishing facilities, pallet and wood-product manufacturers, and horticulture/agricultural operations; a secondary segment comprises district-heating operators served via containerized solutions. Occasional international service deployments are supported but Germany remains the core market.

The company is structured as a GmbH & Co. KG with no external investors, no parent company, no subsidiaries, and no disclosed funding rounds or public listing. With 11-50 employees, the company operates as a classic specialized German Mittelstand firm with deep domain expertise but limited geographic footprint and no disclosed digital, AI, or software product surface.
