Closed Expansion Tank

The pump is designed to reduce the number of switches and compensate for changes in water flow. A properly selected expansion tank prevents sudden pressure fluctuations in the system and extends the life of the system components and the pump.

Technical Specifications

* The membranes in the closed expansion tank are of the bellows type.

* System water does not come into contact with the sheet metal tank.

* Therefore, all ATABOYLER closed expansion can be used in both heating/cooling and plumbing.

* The membranes used are EPDM. It is the highest quality membrane polymer that can also be used in food applications. It does not cause odor.

* ATABOYLER closed expansion tanks operating temperature ranges are -10°C, +100°C.

* Antifreeze used in the cooling system does not affect the membrane.

* ATABOYLER closed expansion joints are coated with electrostatic powder paint.

* Tanks of 50 liters and larger have feet.

* In closed expansion tanks of 100 liters and above, there is a pressure gauge and gas valve in a special housing on the side surface.

* The closed expansion chamber is filled with nitrogen to provide pre-gas pressure. When adjusting the pressure at the location of use, air can also be used instead of nitrogen.

* Since the water circulating in the heating systems will not evaporate, there is no need to add water to the system frequently.
