Hydro-DEZHI定壓罐適用于泵、飲用水，有一個固定的飲用水丁基膜。這些定壓罐是由碳鋼制成。膜被設計為了避免水在罐中停滯而造成任何細菌的生長。定壓罐：用于定壓系統、水泵、防水錘等。

Hydro-DEZHI: is a line of compact 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.

Extra-DEZHI膨脹罐適用于現代安裝，配備丁基橡膠和不銹鋼的法蘭。這種膨脹罐適用于飲用水使用、熱飲用水、加熱、鍋爐、誰錘防護、水泵等。
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.

Ultra-DEZHI采用丁基膜是絕對無毒和適用于飲用水。這種膨脹罐容積利用率高，采用可更換的膜，壓力罐用于防火系統和水密封系統。
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.

Water-DEZHI定壓罐可更換皮囊。這種定壓罐適用于現代安裝，并且適用于各種水泵的應用。他的實際有效容積比平常的壓力罐更大。膨脹罐可以長期保持壓力，在系統中發揮作用。這種膨脹罐可以更換不銹鋼法蘭。定壓罐：用于定壓系統、水泵、飲用水儲存、食品工業等。
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.

Inox-DEZHI完全是不銹鋼做的。他們尤其適用于系統鍋爐、板式換熱器的衛生熱水。對于高衛生標準完全適用，而且產品生命時間幾乎是無限的。壓力罐還可以用于預防水錘減少噪聲。
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 and 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.
