Over 40 years of efficient air, gas and vapor movement and compression for critical and challenging processes.

ExVel™ turbo fans have unique, industry leading impeller and bearing technologies delivering the highest differential pressures available in the fan industry. They can replace more costly centrifugal compressors or multiple blowers with a single unit. Our fans can be produced from a variety of materials, are gas tight, and are applied in a wide range of operating pressures and temperatures.

Benefits of Turbo Fans

  • A single ExVel™ turbo fan can deliver flows and pressures, which may take the place of multiple other fans or blowers, which are limited in flow or pressure rise capability, saving substantial space, energy, and maintenance costs over the life of the equipment
  • Designed for efficient and reliable performance in challenging applications, which may require high pressures, high temperatures, and/or aggressive or hazardous process gases
  • Gas tight standard design, available in a variety of materials of construction, fully automated control options.
  • Over 40 years of experience with thousands of installations in numerous applications.

ExVel™ Turbo Fans

Unique impeller and bearing ​technologies can provide up to 4 times more pressure rise in a single stage than traditional fans and blowers while handling volumes up to 200 m3/sec (400k cfm). Several times higher pressure development can be achieved in multi-stage arrangements.

Our turbo fans are a mainstay for process air, process gas, and MVR (Mechanical Vapour Recompression) applications, providing reliable and efficient performance to the plant owner.

Features

  • Up to 2.0 compression ratio single stage (standard air density basis).
  • From full vacuum to 20 bar (290psi) design pressures.
  • Gas tight casing design standard.
  • Materials of construction options to meet challenging process gases & environments.
  • Wide turn-down capabilities with several control options.
  • Options to meet industry standards such as, API, PIP, PED, ATEX and more

ExVel™ Composite

Howden's ExVel Composite turbo fans have revolutionized safety, reliability, and performance in the fan industry. Our unique carbon fiber composite technology is specifically engineered to combat high-cycle fatigue and results in exceptional life and reliability. Combined with our unique ExVel turbo fan technologies, Howden offer unmatched fan performance and reliability.

For applications requiring start/stop cycles or process/load changes, the ExVel Composite has changed the game with technology, which can eliminate fatigue cracks and failures known to plague steel impellers. This allows users to substantially reduce and even eliminate unplanned downtime, planned shutdowns, and routine maintenance costs related to steel fan impeller and fatigue, and more importantly increase reliability and plant safety.

Mechanical Vapor Recompression

Howden understands the unique process, aerodynamic, mechanical, and operational challenges requirements of Mechanical Vapor Recompression (MVR) applications, which differ from almost all other applications for rotating machinery industry.

The ExVel™ turbo fan is relied upon across thousands of installations in more than 70 countries to provide the optimum MVR vapor compressor solution. With our extensive MVR application experience over 45 years, we have the know-how to provide the best solution for your plant with our industry leading technologies.

Our unique ExVel turbo fan impeller technologies are unsurpassed in fan industry in terms of strength, rigidity, and load capability. Our fan rotor system is designed and constructed for the application with impeller, shaft, and bearing technologies to stand up to the demanding conditions imparted by tough MVR applications due to process and temperature or chemistry challenges.

While MVR process systems are initially specified by the user to operate in clean steady state conditions, unforeseen process foaming or carryover may occur due to process or operational changes, which can lead to difficult operating condition and environments for the vapor compressor. To provide the highest degree of reliability, users have relied on Howden’s unique ExVel turbo fans to keep their operation online.
