Designed for your process
The medium, temperature and loads determine the materials and design. Structural calculations, drawings and manufacturing are carried out in Latvia.
Design and manufacturing
Glass fibre and steel for industry
Tanks built for acid, caustic and time
Chemical tanks, scrubbers and ducts in glass fibre up to eight metres in diameter, and steel fuel tanks from Valtank. We have manufactured GRP equipment in Latvia since 1993, with sales support in Gothenburg.

From process requirements to finished equipment
Capacity for large vessels
Vessels up to eight metres in diameter are made in Ventspils. The location by the port allows large structures to be delivered by ship.

A flue-gas condenser that did not fit on the road
The picture is from the port of Aarhus: a flue-gas condenser 5.5 metres in diameter that travelled by ship. That is how the largest vessels leave the Ventspils factory.

How an enquiry works
Choose product and design
Size, wall and equipment. If you are not sure, choose “Not sure”.
Answer what you know
Medium, temperature, pressure and site. A drawing is often enough.
Collect several products
Tanks, scrubbers and steel tanks in the same enquiry.
To the right company
Glass fibre goes to Welna-Andrén, steel to Valtank. You get a reference number per company.

Three companies, one contact per material
Glass fibre is sold from Sweden and made in Latvia. Steel tanks are made and sold by Valtank. You send one enquiry, and we make sure the right company gets it.
In Latvia since 1993
Valmiera-Andren started in the glass-fibre workshop at the Valmiera Glass Fibre Plant, as a joint venture with Swedish Sten Andren AB. The story goes back further than that.
