Minifill-E wall mounted Pressurisation Units from ELCO are  designed to automatically top up and maintain the minimum pressure requirements of modern low/medium temperature sealed heating, cooling and chilled water systems. A pumped pressurisation unit also removes the need for cold water header tanks with associated pipe work, or eliminates reliance on mains pressure to provide the system head. Minifill wall mounted models are single pump only, with the option of electro-mechanical or electronic controls. The floor standing twin (duty/standby) pump model is available with electronic controls only.

Electronic versions utilise a 16 character back lit LCD display and keypad for viewing operation and system information.
