Tank used for FRP Filters and Softeners are made of composite material. Acomposite 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 trust. 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.
Automatic Controls: FRP Filters and Softeners are equipped with an automatic control system. Top mounted for small sizes, side mounted for medium sizes and using a nest of diaphragm valves with stager for the big ones. this main control is hydraulically actuated to accomplish the regeneration steps of backwash,
rinse, service and brine injection for water softeners and actuated by a 7-day clock timer, which permits the regeneration at any time of the day and night, an or every day of the week. The additional provision for individual adjustment of the backwash
cycle and the manual exception. Duplex twin and several units in parallel connection with one or any unit in service and another as stand-by is also adaptable with this controller. Regeneration initiated by water meter and any other mode can be performed with this controller.
