Downflow and Horizontal Economizers

The economizers come with three control options dry bulb, enthalpy and differential enthalpy. (Photo above shows the three fresh air hoods on the Horizontal Discharge Configuration).

Trane Communication Interface (TCI)

Available factory or field installed.This module when applied with the Micro easily interfaces withTrane’s Integrated Comfort™ System.

Variable Frequency Drives (VFD)

Variable Frequency Drives are factory installed and tested to provide supply fan motor speed modulation.VFD’s, as compared to inlet guide vanes or discharge dampers, are quieter, more efficient, and are eligible for utility rebates.The VFD’s are available with or without a bypass option. Bypass control will simply provide full nominal airflow in the event of drive failure.

Trane factory built roof curbs

Available for all units.
