Water storage tanks are adapted to the advanced technology of hot dip galvanized inner tank, which fuses to solid steel at about 450°C to 500°C . The result is a tough surface that effectively resists the corrosive attacks of hot water chemicals, thus ensuring a long life span of water tank, especially suitable for the areas of hard water.
PUF polyurethane foam insulation is injected and surrounds the inner tank, filling the space between the inner tank and outer tank thus providing an exceptionally good heat retention barrier. This helps to reduce the energy cost by minimizing standby heat loss.
Each tank is provided with a pressure relief valve (PRV valve). It protects the tank against excessive pressure by releasing its contents safely.
