OMERASTORE, a subsidiary of HLE Surface Technologies GmbH, is specialized in manufacturing glass fused steel tanks and silos. The company has experience in producing enameled steel components for most various applications and innovative engineered products since 1838.

The bolted tanks are made of glass fused steel plates and galvanised steel ring stiffener, fixed and sealed on a concrete slab. Vitreous enamel coating is the perfect system to combine the benefits of steel and glass in one compound material. These tanks are ideally suited for biogas plants, where durability, gas tightness and chemical resistance are essential for reliable long-term operation.
