Wilo-Atmos GIGA-NHT Pump

The dedicated pump for district heating and industrial heat supply applications..

Standardised dimensions, different motor variants, impellers and sliding directional seals make the Wilo-Atmos GIGA-NHT a universally applicable standardised pump for transporting hot fluids. Its heat and pressure-resistant design offers high reliability for transporting water with temperatures ranging from -20 to above 200 °C, as well as oil with temperatures from 0 – 350 °C. The pump, which has been specially developed for continuous operation, is characterised by low life cycle costs, as its self-cooling technology means that there is no need for an additional cooling system and its roller bearings are maintenance-free. With an MEI > 0.4 and the use of IE3/IE4 motors, it has a high overall efficiency. Energy consumption can be further reduced by means of speed control using an optionally available Wilo-EFC. In case of maintenance, the spacer coupling ensures that the mechanical seal can be replaced as quickly as possible. In this case, Wilo offers additional, supplementary services ranging from commissioning to maintenance, and the comprehensive WiloCare full-service package is designed to ensure optimum operational reliability.

Your advantages
