With our extensive MVR application experience over 45 years, we understand the unique process, mechanical, and aerodynamic challenges of MVR applications, and we have the know-how to provide the optimum turbo fan solution for your plant with our industry leading technologies.
Our unique ExVel® turbo fan impeller technologies are unsurpassed in industrial 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 loads imparted by tough MVR applications due to process, fouling, disrupted flow, and temperature or chemistry challenges.
While MVR process systems are initially 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 to work through tough MVR conditions, users have relied on Howden’s unique ExVel turbo fans to keep their operation online.
All data above represents Howden’s standard product configurations when properly installed and with normal operation and maintenance.
The strong, tough, and reliable impeller technology unique to Howden's ExVel turbo fans.
Several different bearing technologies are available to either minimise cost or maximise life and reliability.
Low rotor stress, less sensitivity to fouling, more reliable service.
Impellers and casings are fabricated from ductile alloy plate (no castings) making them more forgiving in unexpected process conditions. All component interface connections are machined.
Howden’s ExVel turbo fans can be manufactured from a variety of materials to meet specific process conditions, including:
Besides standard in-process NDE and quality checks for every MVR turbo fan, and regardless of how large any unit may be, every fan is run tested at the factory before shipment to ensure the highest operational quality and reliability from the very start.
ExVel turbo fans also offer many standard and custom design and component options to further enhance your plant's ease of operation and maintenance, and increase reliability and uptime.
Howden understands the unique process, aerodynamic, mechanical, and operations requirements of MVR applications.
