Haase Tank GmbH

Haase Tank GmbH, based in Großröhrsdorf near Dresden, Germany, has manufactured glass fiber reinforced plastic (GRP) separators and tanks for water and wastewater applications for over 50 years. Originally founded as Haase GFK-Technik GmbH, the company was renamed Haase Tank GmbH in 2017 and now employs nearly 50 people, distributing products worldwide through more than 60 certified partner companies in Germany alone. Haase's product line is divided into light liquid separators and grease separators, both built using seamless spherical GRP construction that eliminates joints and corrosion. The LPA series coalescence separators (NS 6 to NS 20) feature filterless coalescence technology and hold building inspectorate approval Z-54.3-537, while the LPZ series (NS 10 to NS 20) combines class II petrol separation and class I coalescence with inlet closure safety, approved under Z-54.3-498. Both lines comply with DIN EN 858-1 and DIN 1999-100/101. For grease separation, Haase offers the drive-over FP type with three-layer GRP/polymer concrete/GRP construction rated for heavy vehicle loads without additional concrete slabs, the walk-over FG type in fully seamless GRP, the compact FS type for constrained spaces, and the in-building FK type—delivered in rollable sections fitting through standard 600×600 mm doorways for retrofit installations. All grease separators comply with DIN EN 1825-1 and DIN 4040-100 with approvals Z-54.1-526 and Z-54.1-540. Nominal sizes range from NS 2 to NS 25 for grease separators.
