Submerged centrifugal blowers
Howden supplies highly specialised blower packages for the nuclear industry and equipment for a number of other applications. Howden lead the way in developing submerged helium blowers and supplied the first submerged helium blower utilising active magnetic bearings for the inherently fail-safe pebble bed modular reactor (PBMR) program in South Africa.

Key benefits

Submerged blower technology was developed from Howden's experience of CO2 Gas Circulators from the 1990s and beyond to meet the requirements of the next generation of gas cooled reactors using helium gas as the primary heat transfer medium operating at inlet  pressures of typically 90 bar.

Standard features

These blowers are generally running in air at around 70 bar pressure.

Other information

We now have the capability to design and supply a wide range of submerged blowers utilising active magnetic bearings and fully submerged high speed electric drives, in combination with a range of aerodynamically efficient impellers with high running and tip speeds suitable for helium and other gases.
Detailed specifications

We also developed a non-nuclear niche market principally in the UK and Far East for submerged blowers in gas flow calibration loops. We have recently been involved in various design projects and feasibility studies for the use of submerged blowers and circulators in demonstration plants for Generation IV nuclear and fusion reactors.
