RTHD with AFD

To meet the increasing for superior full load and part load performance under varying condition and drivers application, Trane is proud to introduce model RTHD with Adaptive FrequencyTM Drive (AFD) helical rotary liquid chiller. The introduction of this offering chiller is an exciting step of forward in enhancing energy-efficiency, operational cost-effectiveness, application versatility, ease of installation, control precision and reliability. The new chiller is designed to deliver proven Series R performance, plus the benefits of improved part load performance and reduced in-rush current associated with AFD.

While AFD application on centrifugal chiller is very much dependant on “LIFT” reduction associated with reduced cooling tower temperature, AFD on screw compressors, being volume displacement type, operates well under part load at constant tower temperature or little temp relief.

Features and Benefits
