GRP technology
proven by standards
Glass Reinforced Plastic (GRP), filament winding and construction according to AD-Merkblatt N1, BS 4994 and DIN 18820: the foundation of every Tara filter.
Why GRP?
GRP (Glass Reinforced Plastic) combines the chemical resistance of polymers with the mechanical strength of glass fibres. Unlike steel vessels, a GRP filter does not corrode, requires no internal coatings and retains its full load-bearing capacity throughout its entire service life, at a significantly lower weight.
Dual Standards
We adhere to globally recognised standards, the German AD-Merkblatt N1 and the British BS 4994, because it is precisely these dual standards that ensure the impeccable, highest quality of our pressure filters.
All other European standards are based on these standards.
The standard that guarantees material quality, performance and operational safety.
Our in-house R&D team sizes every filter according to flow rate, filter media and pressure. Calculation according to AD-Merkblatt N1 and BS 4994.
Before delivery, every filter is tested at a test pressure of 3.75 bar, i.e. 150% of the working pressure.
Position of connections, colour (standard RAL 5015), vinylester lining for ozone and higher working pressures up to 6 bar, according to the project.
