Fenotec

What Fenotec does

Fenotec GmbH is a privately held German specialty manufacturer, founded in 1972 and headquartered in Beelitz, Brandenburg, focused on leak protection systems and engineered films for storage tanks containing oil, chemicals, water, and other water-pollutant substances. The company's product portfolio is anchored by its FENOSAFE family of inner-tank liners — including FENOSAFE FUEL/CHEMICAL (holding DIBt general technical approval Z-65.30-562), FENOSAFE U/BLUE (DIBt Z-65.30-487), and FENOSAFE-LINER for small sewage plants — supplemented by mobile systems such as folding tanks, refueling surfaces, and gas protection fences, as well as custom engineered products including urban planters, silopress pistons, the Thermotank thermal storage product, and dome covers. Fenotec's technical differentiation rests on proprietary manufacturing techniques, including patented unmanned installation methods for inner-tank liners and a patented sewn-fleece construction process.

The company's business model is a direct, B2B, project-by-project sale of bespoke engineered products to industrial, commercial, environmental, civil-protection, and municipal customers, with no public pricing and no disclosed recurring-revenue component. Installation and field deployment are executed through a network of WHG (Wasserhaushaltsgesetz)-certified partner firms, which is the legally required channel for water-pollutant-handling infrastructure in Germany. Revenue is generated from one-time product sales plus professional services covering repair and maintenance. Fenotec maintains multilingual commercial presence (five-language website) and exhibits at industry trade fairs such as UNITI Expo 2026, indicating a DACH-anchored but internationally oriented go-to-market.

Fenotec is structured as a private GmbH with no external funding rounds, no M&A activity, and no disclosed investor base; the firm is undergoing an active internal succession-planning process in which a Prokurist has been appointed with an explicit management mandate, suggesting a founder-to-second-generation leadership transition is underway. The company operates with 11–50 employees and is positioned as a long-tenured Mittelstand specialist rather than a high-growth venture.

Core offering

FENOTEC manufactures and supplies bespoke leak protection linings (Leckschutzauskleidungen) for underground and above-ground storage tanks used with fuels, heating oil, chemicals, AdBlue/AHL, and service water. The company complements this core range with mobile containment systems (folding tanks, refueling surfaces, gas protection fences) and custom technical film fabrications including thermal storage solutions, silage press pistons, and urban planters.

Product overview

Fenotec is a specialist provider of industrial leak protection lining systems and mobile containment solutions, founded in 1972 and based in Beelitz, Germany. The product portfolio centers on FENOSAFE-branded leak protection linings — including FENOSAFE FUEL/CHEMICAL for fuel and chemical tanks, FENOSAFE U/BLUE for diesel, heating oil, and AdBlue, and FENOSAFE-LINER for wastewater applications — applied across underground and above-ground storage tanks, tank rooms, and small treatment plants. This core lining range is complemented by a suite of mobile systems (folding tanks, refueling surfaces, flexible dividers, gas protection fences) and a bespoke custom fabrication division (urban planters, silopress pistons, dome covers, and Thermotank Vario/Upcycling thermal storage solutions). Products are individually measured, fabricated, and installed by WHG-certified specialist companies, with DIBt approval and collaboration with TÜV, BAM, and PTB. Fenotec does not operate a unified software platform; its offerings are physical industrial systems with associated technical documentation and downloadable materials.

Direct peers

• Dehoust GmbH: Dehoust is a German manufacturer of heating oil and diesel storage tanks as well as rainwater harvesting systems. FENOTEC's leak-protection linings are routinely retrofitted into Dehoust tanks, making the two companies complementary but closely aligned in market positioning and customer overlap.
• NAWA Heizöltechnik GmbH: NAWA Heizöltechnik is a German specialist in heating oil tank safety, leak protection, and tank room lining. It competes directly with FENOTEC's FENOSAFE U/BLUE and Tankraumauskleidung lines for the same commercial and residential heating-oil storage customers in Germany.
• Mall GmbH: Mall GmbH is a German manufacturer of small wastewater treatment plants, separators, and rainwater harvesting systems — directly comparable to FENOTEC's FENOSAFE-LINER line for small sewage plants and collection pits. Both target municipal and private operators of decentralized water and wastewater infrastructure under German environmental regulation.
• Otto Graf GmbH (GRAF): GRAF is a leading European manufacturer of plastic rainwater and wastewater tanks, with a comparable product philosophy of modular plastic containment systems. GRAF addresses the same rainwater and wastewater tank retrofit and new-build market that FENOTEC's FENOSAFE-LINER and Brauchwasser product lines serve.
• Roth Werke GmbH: Roth Werke is a German producer of plastic tanks, heating oil storage systems, and rainwater harvesting solutions. As an upstream tank OEM with overlapping customers in German fuel and water storage, Roth represents both a potential channel partner and a direct adjacency to FENOTEC's liner business.
• KVT-Frenzel GmbH: KVT-Frenzel is a German specialist in tank and container protection, repair, and industrial coatings. It overlaps directly with FENOTEC's leak-protection lining business for fuel, chemical, and process tanks, serving the same industrial customer base in Germany.

Regional players

• Premier Tech (Rewatec): Premier Tech, via its Rewatec brand, manufactures and distributes rainwater harvesting and wastewater storage solutions across Europe. It competes with FENOTEC's rainwater/service-water lining portfolio and operates in overlapping geographies (Germany, Austria, neighboring EU markets) with similar end-customers.

Emerging players

• AGRU Kunststofftechnik GmbH: AGRU Kunststofftechnik is an Austrian manufacturer of high-performance technical plastics, geomembranes, and industrial liners used in tank, landfill, and containment applications. While much larger and broader in scope than FENOTEC, AGRU is materially comparable as a supplier of technical films and membranes in industrial leak-protection settings.
