What Haase Tank does
Haase Tank GmbH is a privately held German specialty manufacturer of glass fiber reinforced plastic (GFK) tanks, storage containers, separators, and linings, headquartered in Großröhrsdorf, Saxony, with continuous manufacturing operations since 1968 and formal GmbH incorporation in 1991. The portfolio centers on double-walled, permanently leak-monitored heating oil tanks (Kellertanks assembled on-site in basements and Erdtanks installed underground), complemented by light liquid and fat separators, flat-bottom and spherical storage tanks for water-pollutant liquids, Wärmespeicher (thermal energy storage tanks), pellet tanks, and GFK linings and shaft systems for channel rehabilitation. Underlying technology combines GFK composite materials (polyester and vinyl ester resins with glass fiber mats, rovings, and synthetic fleeces) with proprietary processes including a 3-layer spherical sandwich construction using polymer concrete as the load-bearing monitoring layer, robot-controlled fiber resin spraying, semi-automated lamination of panels up to 35m, water-jet cutting of components up to 4.50m x 4.50m, and on-site "unfolding" tank assembly that allows tanks to pass through standard access hatches without cranes or structural modification.
The company serves a horizontally diversified customer base across residential homeowners (basement and underground oil tanks), industrial and commercial customers (Deutsche Bahn, IKEA Germany, Bundesdruckerei, Sachsenmilch, paper mills), food service and hospitality (restaurants in Düsseldorf and Krefeld using FK04-400 fat separators), fuel retail chains (a Scandinavian petrol station operator with multiple hundred sites in Sweden and Denmark), and municipal and infrastructure projects. Haase generates revenue primarily through one-time hardware sales of GFK tanks, separators, and linings, sold directly and through a network of approximately 60 certified partner installation firms across Germany, Europe, and worldwide; pricing is quote-based per project, no public price list exists, and the company maintains annual partner tagungs and Fachseminare on separator systems and shaft renovation for authorities, engineers, and expert organizations. The company is led by three Managing Directors (Thomas Falkenbach, Thomas Wobst, Tino Vilsmeier), holds AMS BAU certification from BG BAU (2023), and positions its portfolio under DIBt and AwSV regulatory frameworks while extending into GREEN FUELS READY certification for HVO and other renewable liquid fuels to align with Germany's heating transition.
