The two-shell welded construction allows the tank to withstand high pressure and therefore adds safety to your installation. The butyl bladder separates air from water and prevents waterlogging while saving space and energy. These devices are indicated for use in hot water, solar and cooling systems, in addition to being compatible with glycol.
