ydro-DEZHI：is a line of compact expansion tanks for pumps,potable water,with a fixed potable water butyl membrane.These tanks are made of carbon steel without welding that eliminates any sharp cutting edges inside the tank.The shape of the membrane is designed to avoid any water stagnation and therefore the growth of any bacteria.
These tanks are used with water booster system,pumps and as anti-water hammer.
Water-DEZHI: with a replaceable membrane. This line is ideal for every modern installation and can be applied to any type of pump. The real volume of the pressure vessel is much greater than normal that of normal tanks of the same dimension with smaller dimensions. A compressor is not necessary since an air cushion, separated from the water by the membrane, maintains a constant pressure in the tank. These tanks can also be provided with stainless steel flanges.
These tanks for water booster system ,pumps, potable water storage.
Extra-DEZHI: is ideal for every modem installation These tanks equip with butyl membrane, stainless steel flange (fittings).
These Expansion vessel for potable water use, hot potable water, heating, boilers, water hammer arrester, pumps.
Inox-DEZHI: are entirely made of stainless. They are especially used for systems that produce sanitary hot water produced by a boiler or from plate heat exchangers. They are excellent choices for situations that require high hygienic standards and a product life time that is practically limitless. The membrane is absolutely non-toxic and potable drinking an
d food grade. This model of tanks is particularly useful for anti-water hammer effecting water systems, preventing vibrations or noises. They can also be used with reduced flow pumps.
Ultra-DEZHI with butyl membrane are absolutely non-toxic an potable drinking. This model of tanks, also for their reduced volumes, are replaceable membrane pressure tanks for fire protection systems and water pressurizing systems.
