Henze-harvestore Gmbh

What Henze-harvestore Gmbh does

Henze-Harvestore GmbH is a German specialty manufacturer of bolted steel tanks and silos, founded in 1959 by Erwin Henze and headquartered in Unna, Germany. The company designs, engineers, and assembles custom container systems from individual steel segments using coated and uncoated steel, proprietary TRIFUSION enamel, and V2A/V4A stainless steel (grades 1.4301 and 1.4404 / AISI 304/316L). Its product portfolio spans four primary verticals: biogas (fermenters, buffer/hydrolysis tanks, digestate and beet storage), agriculture (tower silos for grain, CCM, fermented fodder, bulk materials, and MBM), industry (custom process and storage containers), and municipal water/wastewater (digesters, anaerobic reactors, sludge processing, slurry silos, drinking water tanks, and gas storage). Container capacities range from 50 m³ low-pressure gas depots up to 20,000 m³ digestate depots, with diameters up to 50 m.

The business operates a project-based, direct sales model offering an 'Alles aus einer Hand' (one-stop) service covering consultation, statics, construction design, planning, on-site assembly, and optional leak testing. Pricing is custom quote-based, with revenue derived from one-time project contracts, equipment/accessory sales, and recurring refurbishment, conversion, and maintenance services for gas depots (including its own and competitors' units). Customers are primarily enterprise and government buyers — biogas operators (e.g., Zorg Biogas AG, Suiker Unie), municipal utilities (e.g., Niersverband, Stadtwerke Lauffen, Stahnsdorf treatment plant), industrial processors, and agricultural operators — with reference projects executed across 15+ countries including Germany, Netherlands, Ukraine, UK, Saudi Arabia, Japan, Mexico, and Ethiopia. The company maintains four German sites (Unna headquarters plus second Unna plant, Bad Oldesloe/Rümpel, Zörbig, and Landsberg), employs 65 staff, and holds key certifications including SCC, WHG specialist company status, General Building Authority Approval, and JGS General Type Approval. Distribution is single-channel direct sales with no public API, no software platform, and an enterprise field-sales go-to-market motion.
