Wilo-Atmos GIGA-I
The universal glanded pump for heating, air-conditioning and cooling applications in large buildings.
The universal glanded pump for heating, air-conditioning and cooling applications in large buildings.
The Wilo-Atmos GIGA-I offers a wide range of components and materials for a variety of applications, mainly in the field of building services and in industrial environments. It can pump different fluids at temperatures from -20 °C to +140 °C making it particularly suitable for air conditioning and cooling applications. Any condensate that forms can be selectively discharged via an outlet.
Equipped with state-of-the-art pump hydraulics and IE3/IE4 motors, the pump is as reliable as it is energy-efficient.
The cast components with corrosion-resistant cataphoretic coating also ensure a long service life.

Technical data
- Permitted temperature range of the fluid: -20 °C to +140 °C
- Max. ambient temperature 40 °C
- Mechanical seal for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.
