Data Centers

Looks can be deceiving...

While outwardly simple, belt drives on CRAC units are not as simple as they appear. Some problems include:

  • Tendency to slip and to produce contaminating black rubber dust
  • Short center distances with high belt flex rate leads to premature belt failure
  • Drives are hard to access for maintenance
  • Very time-consuming to re-tension rubber belts correctly
  • Frequently operating above normal design temperatures for V-belts

Count on Fenner Drives, we’ll got the solutions to eliminate these problems and help make your data centers operate efficiently!

Drive Belting Tensioners Pulleys

  • Increased air flow – Reduced belt slip increases air-flow and allows your CRAC units to run at optimum designed efficiency levels from the outset
  • Reduced dusting – No more black rubber V belt dust, whose carbon black can short out electrical connections and is extremely difficult to remove... plus filters last longer!
  • Lasts longer than rubber V belts – extremely high strength and low elongation under load results in increased belt longevity and durability
  • Elevated temperatures? No problem – No loss in performance at extreme temperatures — from -40°F to 240°F (-40°C to 116°C)
  • Fast, easy installation – Easy to use twist-lock design is made to length by hand, great for captive and fixed center drives
  • Reduce inventory – eliminate the need to purchase and inventory numerous belt lengths

PowerMax T-Max Belt Tensioners

Take the slip out of V belt driven HVAC systems. T-Max spring-loaded tensioners automatically take up the slack – decreasing downtime, reducing operating costs and saving energy.

T-max Tensioner on a Data Center Centrifugal Fan
  • Increase drive efficiency – Rotary spring-loaded design maintains optimum drive belt tension automatically, eliminating slip and torque losses associated with loose fitting V-belts
  • Reduced dusting – Drives running at designed parameters means less dust caused by belt slip
  • Easy belt installation – allows V-belt to be installed without tools or moving drive components
  • Increased air flow – Reduced belt slip increases air-flow and allows your CRAC units to run at optimum designed efficiency levels from the outset
  • Reduce maintenance costs – Cut down component replacement costs due to premature belt failure. Also eliminate system downtime caused by periodic belt re-tensioning
