Howden's ExVelTM Composite turbo fans feature unique carbon fiber composite technology specifically engineered to combat high cycle fatigue and result in exceptional life and reliability. Combined with our unique ExVel turbo fan impeller and bearing technologies which can provide up to 4 times more pressure performance than traditional fans, Howden can offer unmatched fan performance and reliability from the simple to the most challenging applications.
The lightweight and resilient composite impeller technology is immune to fatigue cracks and failures which plague steel impellers therefore substantially reducing and even eliminating for unplanned downtime, planned shutdowns, and routine maintenance costs related to impeller fatigue, and more importantly increasing reliability and plant safety.
ExVel Composite impellers allow unlimited speed control and load changes and fast acceleration and deceleration, all resulting is significant energy savings potential during and in between process cycles. It eliminates the need for guide vanes or dampers thus eliminating the cost for this equipment and its maintenance. The lightweight and low inertia properties also mean lower loads for connected components such as shafts, bearings, and couplings, and therefore longer operational life and less downtime, spare parts, and maintenance.
ExVel Composite impellers have a virtually infinite fatigue life which substantially reduces the risk of catastrophic failures and potential damage to surrounding equipment and property and possible injury to personnel.
Because of the nearly infinite fatigue life as well as the inherent properties of ExVel Composite impellers, there is no need for anything more than an annual visual inspection of the impeller during annual planned shutdown. This eliminates the requirement for more frequent planned shutdowns for non-destructive examinations of impellers made from steel.
The superior reliability and fatigue life of ExVel Composite impellers, combined with its uniquely lightweight properties that reduce loads to associated components, such as bearings and couplings, extends their service life. This provides unparalleled total reliability, thereby reducing planned and unplanned downtime and generating longer operational uptime.
The low weight and inertia of ExVel Composite impellers allow these fans to be accelerated and decelerated quickly with variable speed control, yielding substantial power savings between cooling cycles and therefore lowering the carbon footprint (i.e. Glass quenching and cooling applications).
ExVel turbo fans are unique in all of fan industry and can generate up to four times (4X) the pressure of traditional centrifugal fans. ExVel turbo fans can be selected to provide enhanced flow and pressure rise performance to improve production across different glass recipes, batches, and changing ambient or seasonal cooling air conditions.
ExVel Composite offers User’s the potential to save energy and lower operating costs, and also achieve higher flow and/or pressure performance to enhance or even increase production.
