工艺空气

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.

• 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

工艺气体

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.

• Gas processing within oil and gas, chemicals, fertilizer and industrial gas production
• Transfer of off/exhaust gases from combustion processes across industrial sectors

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

通风

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.

• 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.

• 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

离心风机

我们生产从配置简单到完全工程化的风机，可满足各种客户需求。我们拥有知识、经验和能力，可以针对特定需求调整和开发新设计，这在我们的工程能力中可见一斑。

All fans are designed to maximize efficient operation with some reaching over 90% depending on application and operation. Fans are compliant with industry standards as required for each application e.g. API, ATEX, Nuclear certifications.

• CFi - typically, below 100 m3/s in flow and 20 kPa in pressure. Configurable options such as stainless steel construction, carbon ring shaft seal, anti-vibration pads etc. allowing process flexibility
• Engineered - reaching flows of up to 1000 m3/s and pressures of 43 kPa. Open to higher levels of special design aspects such as aerodynamic performance or special materials and construction to support conditions

The axial fan range includes a number of products developed across a number of Howden's current and legacy brand to offer comprehensive coverage of industrial flow and pressure requirements.

The range means we can address many applications with alternate configurations vertical or horizontal placement and different flow control options, from manually adjustable-pitch to variable pitch and variable frequency drives.

All fans are manufactured to high standards for efficient operation and low maintenance through reliable service.

• Variax/PF - proven across a wide range of applications within mining, power, metals and wind tunnels. Variable pitch combining the highest efficiency levels with an exceptionally flexible, customer focused design
• Alphair - heavy-duty axial fans designed specifically for main mine ventilation
• Jetstream AX - ideally suited to provide auxiliary/secondary ventilation within underground mines fans with high efficiencies of up to 85% across a broad operating range.
• VA series - used within applications such as ventilation, aeration and drying, extraction, cooling and air conditioning. Designed for continuous operation and highly dependable with ATEX-classification on request
• UMAF - extensively used with tunnel ventilation/smoke extraction, industrial process for combustion air, and in higher-pressure Direct Air (carbon) Capture. Ideal for applications requiring high efficiency air or extraction of air/gases in flows of up to 400 m3/s. Tested to operate at 200ºC/1h or up to 400ºC/2h to meet tunnel operating requirements
• AP/Q Jet fans - typically used in tunnel ventilation systems using the longitudinal technique with single or bi-directional traffic. The AP/Q range can operate with flows of up to 50 m3/s with thrust of up to 3360N. Tested to operate at 200ºC/1h or up to 400ºC/2h
