At the forefront of industrial process flow technology

Howden has been designing fans to address industrial demands for over 100 years and continues to lead the world in raising energy efficiency, improving reliability and reducing lifetime costs for our customers. Whether in critical positions in heavy industrial processes or auxiliary applications within light industry, Howden has a fan to fit.

Aria di processo

Air is one of the most common ingredients of industrial process and Howden fans have been integral to such processes since the industrial revolution.

Our fans can be used as forced or induced draft to push or draw specified volumes of air through the process. They address a wide range of volumes and pressures, delivering dependable performance to ensure continuous production.

Aim: to provide reliable air flows at selected volumes and pressures into each process stage at the highest efficiency.

Typical processes served
  • Combustion air for boilers, steam generators, incinerators and furnaces for power or process requirements
  • Air transfer within stages of industrial process
  • Air extraction such as dedusting
  • Pressurised air within pneumatic conveying systems for the movement of substances or product
  • Air for wind tunnels - automotive and aerospace research and leisure/body-flying applications
Prodotti applicabili
  • Ventilatori assiali
  • Ventilatori centrifughi

power plant fan

Gas di processo

The industries we serve handle many types of gases within production processes and also as a by-product of the process.

Our fans are central to continuous processes handling gases from Nitrogen, Hydrogen and Noble gases to waste gas. They are designed to be durable and deliver high performance, withstanding the effects of corrosive gases, whilst sealing the gas safely within the fan and process.

Aim: to safely and efficiently move gas flows at selected volumes and pressures within and from each process.

Typical processes served
  • Gas processing within oil and gas, chemicals, fertilizer and industrial gas production
  • Transfer of off/exhaust gases from combustion processes across industrial sectors
Prodotti applicabili
  • Ventilatori assiali
  • Ventilatori centrifughi

Howden also has a comprehensive range of gas compressors should the gas flow and pressure requirements exceed those suitable for our fans.

Ventilazione

Howden fans are relied upon to maintain safe and comfortable conditions for work and transportation, whether it be within industrial facilities or under the ground.

Our fans draw or push large volumes of air through the ventilation system as well as extract waste air, gases and potentially smoke from protected spaces.

Aim: to move required air flows within the system efficiently on a continuous and emergency basis.

Typical processes served
  • Underground ventilation in mines
  • Underground ventilation and emergency smoke extraction in transportation tunnels (road/rail/metro)
  • Ventilation within industrial facilities such as nuclear power plants, naval vessels, industrial plants

Cooling

Howden fans are vital part of process and utility cooling systems using air to dissipate heat to atmosphere. Our products are renowned for their excellent efficiency and low noise performance, which enables operators to engineer the best solution relative to cooling capacity requirements, space on site and noise regulations.

Our fans draw or push large volumes of air through air cooled heat exchangers (ACHE/ACHX), air cooled condensers (ACC) and cooling towers. They are also used within heavy machinery to maintain engines are optimal operating temperatures.

Aim: to remove heat from a process or operating equipment efficiently and within permitted noise limits.

Typical processes served
  • Process cooling for industrial processes such as refining, LNG production, gas compression, cement production
  • Utility cooling for power generation such as solid fuel fired power plants, gas combined-cycle gas turbine (CCGT) plants and nuclear power plants
  • HVAC and refrigeration systems for industrial manufacturing plants and data centers
