Wilo Atmos GIGA-I is a universal dry rotor pump suitable for heating, air conditioning, and cooling applications in large buildings.
Product Description
Wilo-Atmos GIGA-I is a universal dry rotor pump equipped with advanced hydraulic components and IE3/IE4 motors.
Flow range : <450m³/h
Lift range : ≤80m
Max.operating pressure at different fluid temperature : 13bar/16bar
Temperature range : -20ºC~+140ºC
Aplication field :It can be widely used in heating, district heating, air conditioning circulation systems, refrigeration, industrial refrigeration, water supply systems, and irrigation systems.
Summary
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

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.
