Integrated rooftop bus HVAC system for coach and transit applications. Replaces existing roof-mount units with a unit that weighs 42% less and replaces rear-mount units without sacrificing reliability, performance, weight or cost.

Standard Features
  • IntelligAIRE® III Control System: Expanded CAN communications capability; Plugs directly into J1939 network to make more info available; Eliminates the gateway module required between bus & unit controllers; Less weight due to elimination of harnesses; Increased number of I/O for system & component monitoring; Eliminates need for expansion modules external to controller where multiple zones must be controlled independently; Programmable pre-heater function with real time clock activation to start pre-heat when system is off
  • HFC Refrigerant R-134a or R-407C: Environmentally safe alternative providing protection for the earth’s ozone layer
  • The Thermo King X430 Compressor: Engineered exclusively for transport applications; Built for extended service life; Field repairable
  • Next Generation Brushless Motors: Integral electronics; No external controllers; Maintenance free; Advanced diagnostics; Programmable variable speed; Eliminates wiring harnesses, terminals and studs; Failure mode indication
Optional Features
  • S391/S616 Screw Compressors: Exclusive oil management system for increased reliability; Fewer moving parts than reciprocating compressors; Lower noise levels and vibration than reciprocating compressors; Programmable capacity control for fuel savings
  • Electronic Energy Management System: Provides fuel savings with X426, X430 and X640 reciprocating compressors; Programmable electronic capacity control reduces the parasitic load on the engine
