The buffers (inertia tanks) of MasterSOL are ideal for domestic and professional use. They are made from quality, ecological materials for durability over time. During the operation of the boiler or the production of hot water from the solar collector, the water is stored in the inertia tank and can be used hours after the boiler operation has stopped. The inertia tanks maintain the water at a high temperature for a long time, providing hot water when the boiler is off or when the solar collector is no longer producing due to lack of sun.

In a similar way, they can store cold water, with the only difference being that instead of being connected to boilers or collectors, they are connected to water coolers. They are manufactured according to the specifications of DIN 4753 and EN 12897, and checked according to international hygiene standards. Their insulation is made of polyurethane, and its injection is performed with an automatic machine of new generation modern technology.
