POLTANK designs and manufactures pressure vessels in polyester reinforced with glass fibre PRFV for swimming pools, aquariums, water parks, zoos, aquaculture, aquaculture, food and beverage industry, mining, irrigation, drinking water treatment, waste water treatment and desalination. We offer the best solutions in mechanical filtration (sand filters), adsorption (activated carbon), decalcification and demineralisation (ionic interchange) thanks to our 4 production plants where the most advanced techniques are combined, such as winding and casting as well as projection and lamination. The use of glass fibre (GRP) in our processes provides a great mechanical resistance to traction, bending and compression, presenting a specific resistance superior to steel. Furthermore, the material is resistant to electrolytic and chemical attacks, and is ideal for saline and aggressive environments.
