ARCLION seriesOur FRP Pressure Tank is meticulously engineered to withstand a design pressure of 150 PSI, ensuring robust performance in demanding environments.The standard models are available in a diverse range from 5 inches to 80 inches (diameter 130mm to 2000mm).FRP tanksFrom sizes 30" to 80", our tanks feature an upper filling port and a lower discharge port, utilizing food-grade HDPE liners and epoxy resin reinforced with glass fiber winding. Certified by NSF and ISO 9001, these tanks endure over 100,000 fatigue cycles and burst tests at four times their design pressure. The PE food-grade, non-toxic, tasteless rotomolded liners ensure hygienic water storage. Aviation aluminum-modified flanges (6-inch for top/bottom openings, 4-inch or 6-inch for ports) seamlessly integrate with the PE liners via integral rotomolding for leak-proof and pressure-stable performance. This innovative design simplifies filling and discharge operations, reducing potential damage to valves and water distributors. Additionally, an anti-vacuum valve design protects against vacuum-induced or improper overpressure damage.
