The RT-B-A18 AC is a climate-controlled 18-seater electric shuttle bus — pairing the RT-B-A18 platform with a roof-mounted air conditioning system for passenger comfort on hot-weather campus and institutional routes.
Built Around Your Needs (Customization Options)

The Roots EV RT-B-A18 AC is the air-conditioned variant of the RT-B-A18 electric shuttle bus, built for operators who need 18-passenger capacity with a fully climate-controlled cabin. It suits large IT parks, university campuses, industrial complexes, resorts, and township developments in hot or humid regions where passenger comfort on every trip matters. A roof-mounted air conditioning unit keeps the cabin cool throughout the day without drawing meaningfully on driving range, thanks to the same large-capacity LFP lithium battery pack used across the RT-B-A18 range. The high-torque 3-phase AC induction motor and high-current BLDC controller deliver the same confident performance on varied campus terrain as the standard model. Passenger comfort goes beyond climate control — spacious, well-cushioned seating, generous headroom, and a smooth, vibration-free electric ride reduce driver fatigue and improve the experience on repeated daily shuttle routes. The sealed, air-conditioned cabin also keeps dust out, an important consideration for outdoor campus and industrial environments. Built for Indian operating conditions, the RT-B-A18 AC uses robust components rated for heat, dust, and varied terrain. It meets all relevant safety standards and is backed by Roots EV's pan-India service network.
