Wilo-Atmos GIGA-I

The universal glanded pump for heating, air-conditioning and cooling applications in large buildings.

Your advantages
Wilo-Atmos GIGA-I

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 wide variety of applications. 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.


Your advantages

  • Universal use in different applications, with different fluids and temperatures thanks to diverse components such as impellers, motor sizes and mechanical seals
  • State-of-the-art pump hydraulics and IE3/IE4 motor technology for reliable and energy saving operation
  • Long service life thanks to corrosion-resistant cataphoretic coating of all cast components
  • Targeted discharge of condensate when used in air-conditioning systems and chillers
  • Easy installation with the possibility of securing the pump feet for maximum stability
  • Easy maintenance and user-friendly design with optional back pull-out design and cartridge mechanical seal for large pumps

Environmentally friendly features

  • Efficient pump hydraulics and usage of IE3/IE4 motors for high energy saving
  • Efficient design of cast iron components for lowest possible weight
  • Sustainable and carbon-neutral production and processes in our European factories

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.
  • Mains connection 3~400 V, 50 Hz (others on request)
  • Protection class IP55
  • Nominal diameter DN 32 to DN 250
  • Standard version for operating pressure: 13 bar (up to +140 °C) / 16 bar (up to +120 °C)
