Tank used for FRP Filters and Softeners are made of composite material. A composite pressure vessel combines the unrivalled toughness of a polyethylene inner tank and the strength of a glass fiber reinforced with epoxy resin and wound on to a seamless
composite liner that means a strong tank that simply can not rust. These composite pressure vessel tanks have been designed and constructed for the needs of the commercial and industrial water treatment markets and heavy duty use. This non-metallic construction makes our filter tanks maintenance free. Also there are made of NSF/FDA listed materials that make them safe and non toxic.
The strength equals the equivalent steel tanks but are 60% lighter.
They are tested under pressure of up to 161 psi (11 bar) and temperature ranges of up to 65 C. for flange type top and bottom connections.
