Reflex NG 25 expansion tank (gray)

Expansion tank for heating systems produced by Reflex is designed to compensate for the thermal expansion of the heat carrier and maintain pressure in closed heating systems.
In the Reflex NG 25 series tanks, a replaceable membrane is used, suitable for systems with a maximum temperature on the supply line of 120°C, and a maximum temperature on the membrane of 70°C. Developed based on advanced technologies, these tanks have a long operational lifespan, are adapted to challenging operating conditions, and can withstand even critical loads and network instability without issues.
The expansion tank is divided by a membrane into two parts – chambers. One part (air chamber) is filled with pre-charged low-inert gas – nitrogen under pressure, while the other part (water chamber) is designated for the heat carrier.
The tank body is made of high-quality carbon steel with a polymer coating, ensuring long-term durability, protection of the steel base from mechanical damage, and the absence of chips and delamination caused by impacts and excessive loads, maximum effectiveness of corrosion protection, as well as the NG series tanks are environmentally safe. Unique EPDM membrane with a reinforced belt at the attachment point ensures a long service life of the tank.
The heat carrier does not come into contact with air, which prevents liquid evaporation. For the same reason, pipes and radiators do not oxidize due to air exposure, contributing to their extended lifespan. In Reflex expansion tanks, the likelihood of liquid spilling outside the tank is zero.
There is no possibility of air pockets forming, which occur in open-type tanks due to increased pressure at the highest point of the heating system.
There is no need to top up the heating system with the heat carrier, as the operation of membrane expansion tanks for the heating system is significantly simplified.
The uniquely shaped European membranes significantly increase the lifespan of the tanks.
