The model FRPV-4030E Fiberglass RO/UF Pressure Vessel is designed for continuous, long-term use a as a housing for single reverse osmosis and ultrafiltration elements in typical commercial water treatment systems at pressures up to 300 psi.
Any make of 4″x 40″ nominal diameter spiral-wound element is easily accommodated. The model FRPV-4030E must be installed, operated and maintained in accordance with the listed precautions, and good industrial practice to assure safe operation over a long service life.
The high performance reinforced plastic shell must be allowed to expand under pressure; undue restraint at support points or piping connections can cause leaks to develop in the shell.
The end closure, incorporating close-fitting, interlocking metal components, must be kept dry and free of corrosion; deterioration can lead to catastrophic mechanical failure of the head assembly.
DO… read, understand and follow all instructions; failure to take every precaution will void warranty and may result in vessel failure.
DO… inspect end closures regularly; replace components that have deteriorated and correct causes of corrosion.
DO… provide overpressure protection for vessel set at not more than 105% of design pressure.
DO… mount shell on horizontal or vertical members at central span “S” using compliant, vessel supports; tighten hold down straps just snug.
DO NOT… pressurize vessel until double checking to verify that the retaining rings are in place.
DO NOT… work on any component until first verifying that pressure is relieved from vessel.
DO NOT… tolerate leaks or allow end closures to be routinely wetted in any way.
DO NOT… operate vessel with permeate pressure in excess of 125 psi at 120 °F (0.86 MPa at 49°C).
DO NOT… make rigid piping connections to parts or clamp vessel in any way that restricts growth of fiberglass shell under pressure; DIA = 0.01 in. (0.25 mm) and L = 0.3 in. (.8 mm) for a length code -1 vessel .
DO NOT… hang piping manifolds from parts or use vessel in any way to support other components.
DO NOT… operate at pH levels below 3 or above 11.
DO NOT… operate vessel at pressures and temperatures in excess of its rating.
