Wilo-Stratos GIGA-D


Maximum energy efficiency, double safety.
Maximum energy efficiency, double safety.
The Wilo-Stratos GIGA is the ideal high-efficiency pump for use in heating, air conditioning and cooling applications in buildings where large volumes of water have to be pumped to great delivery heights. Wilo-Stratos GIGA offers ever greater operational reliability with the standby pump in the twin-head pump version.
