About SOLAR-PLUS Pressure Tank
Like every closed system in which a liquid's temperature changes, a solar installation also needs an expansion vessel. The Solar-plus expansion vessel plays an important role in this regard when it comes to maintaining pressure. The pressure must not rise too high when the circulation in the collector stops, but also not too low when the outside temperature is below the freezing point. The medium in a solar installation is mostly a mixture of water and glycol, having a high coefficient of expansion. Solar-Plus Expansion Tank can anticipate such temperature fluctuations and maintains the system pressure in a sitting range. 

The high volume of our products uses automated production machinery and testing equipment. Every staff is trained and fully experienced. The majority of our production is done in-house which limited the quality problem from the other manufacture. Every tank is a quantity 100% pressure safety test to ensure the best product going out the door.
