Our FRP Pressure Tanks are designed to store and distribute water under pressure, making them ideal for residential, commercial, and industrial water treatment applications. They are made from high-quality FRP (Fiberglass Reinforced Plastic) material, which is known for its durability and corrosion resistance.
Our FRP Membrane Housings are specifically designed to accommodate RO (Reverse Osmosis) membrane elements. These housings are available in three different sizes: 2.5 inch, 4 inch, and 8 inch. The 2.5 inch housing can withstand working pressures of 300PSI and 1000PSI, the 4 inch housings can handle working pressures ranging from 300PSI to 1200PSI, the 8Inch housings can handle working pressures ranging from 300PSI to 2000PSI.
Our FRP membrane housings are available in two different brands: Winder and Winder-G. Both brands have undergone rigorous testing and have been certified by ISO9001, CE, and NSF. This ensures that our products meet the highest quality standards and can be trusted for reliable performance. Our FRP membrane housings have been subjected to extensive testing, including more than 100,000 fatigue tests and 6 times the bursting water pressure tests. This ensures that our housings can withstand the harshest operating conditions and provide long-lasting performance.
The standard color of our FRP membrane housings is white, but we can also provide custom colors upon request. This allows our customers to match the aesthetics of their water treatment systems or integrate them seamlessly into their existing setups.
