Do the RTAE and RTAF utilize the same compressors?
- The RTAE and RTAF air cooled offerings with VSDs do not share the same screw compressor design.
- The RTAE is configured with GP4 compressors which utilizes Trane’s Adaptive Speed Technology. This new technology allows operation at specific speeds for optimized performance at all operating conditions.
- The RTAE compressor is equipped with a permanent magnet motor resulting in 2 – 4% higher full load efficiencies as compared to an induction motor.
- The RTAF is configured with GP2+ or GP2.5 compressors with internal enhancements of the GP2 compressor family which was designed and developed for the RTAC constant speed compressor.
- Capacity control is achieved by both speed and a slide valve.
