The Adaptive Frequency drive is a Trane TR200 variable frequency drive (VFD) applied to Trane CenTraVac chillers. It represents the combination of Trane CenTraVac chiller controls with Trane frequency drive technology that allows these chillers to be exceptionally efficient during low load or low lift operating conditions. Trane air-cooled Adaptive Frequency drives (AFDG), have transitioned to the Trane TR200 enhanced new platform. The AFDG drive previously used the Trane TR1 platform.

TR200 platform advantages:
  • Enhanced user interface
  • Increased ambient temperature ratings

    The new AFDG drive is available to order via the TOPSS/Lynxsystem now. The Trane AFD is only available through Trane and Trane will service and warranty this AFD.

    The primary purpose of an AFD is to reduce energy consumption by adapting the speed of the motor to changing cooling conditions. Other benefits include improved power factor, soft starts and possible rebate potential.

    What are the recommended applications? AFDs are recommended in a wide variety of applications, but will provide the best returns in applications with the following factors:

  • Large run hours with condenser water relief
  • High unit run hours, especially 24/7 operation
  • Rebate opportunities

    Some applications that frequently combine these factors are:

  • Single chiller installations
  • Dual duty applications like ice making
  • Arenas and sport complexes
  • Hotels

    When combined with existing local Utility Rebate Programs the Trane Adaptive Frequency Drive for Centravac Chillers provides a significant savings opportunity for Trane customers!
