EXPANSION TANKS
Expansion tanks are used in closed heating systems to balance the increase and decrease in water volume caused by heat exchange. In open systems, they are used to regulate pump start-stop functions and pressure balancing during water supply. Depending on the hydraulic pressure of the system, tanks with P = 10 bar are available. Below is the table with technical parameters.
Technical Specifications:
Expansion tanks are of the diaphragm (bladder) type.
Therefore, all expansion tanks can be used in heating, cooling, and water supply systems.
The diaphragms used are made of EPDM, the highest quality food-grade polymer membrane.
Operating temperature range for expansion tanks is -10°C to +100°C.
Antifreeze used in cooling systems does not affect the membrane.
Expansion tanks are coated with electrostatic powder paint.
Closed expansion tanks of 100 liters and above are equipped with a manometer and air vent on the side, enclosed in a special protective housing.
Expansion tanks are pre-filled with nitrogen to ensure pressure stability.
During on-site pressure adjustment, air can be used instead of nitrogen.
Since the circulating water in heating systems does not evaporate, frequent water refilling is not necessary.
