FAN
RETROFITS

Replacing a fan is a major financial commitment. In addition to the cost of the fan itself, there may be the expense of rebuilding foundation and proving new ducting and auxiliary equipment, and compromises always have to be made when a new fan is installed in a space designed for its predecessor.

Our comprehensive and flexible retrofit services enable us to replace critical parts of any axial fan installation, no matter how old it is or where it is located, with the most up-to-date upgrades. This brings you the superior aerodynamics, low dynamic forces and minimal vibration levels of state-of-the-art axial fan technology without the capital investment or downtime of installing a new fan.

Retrofit is the fast, economical route to enhanced performance:

  • Improved availability and reliability
  • Increased pressure
  • Improved fan efficiency
  • Greater flow volume
  • Improved operational safety
  • Reduced CO2 emissions
  • Reduced power consumption
  • Extended equipment life
  • Longer intervals between servicing
  • Reduced maintenance costs

The conversion of fixed pitch axial (mixed flow) to variable pitch axial fan (variax) also has the following advantages:
 
i.    Power savings in part load condition
ii.    Ease of maintenance
iii.    Avoiding frequent failures
