Crafted for

DURABILITY, EFFICIENCY, & SAFETY

ShuttleAIRE leverages Thermo King’s long history of transport refrigeration and HVAC, resulting in the most reliable HVAC system available for shuttle applications. Each system is engineered and tested to last a minimum of 5 years or 400,000 miles with standard maintenance (see your dealer for warranty details).

Every component has been selected to provide the highest level of system efficiency to maximize passenger comfort.

  • Proper component selection and sizing decreases engine load for maximum fuel savings 
  • Thermostatic Expansion Valves (TXV) precisely regulate refrigerant flow for the highest efficiency, providing more capacity when needed vs. block valves or orifice tubes 
  • Oversized condensers ensure proper cooling in extreme climates 
  • Properly-sized fans give maximum cooling capacity with lower power consumption

Each ShuttleAIRE product has been developed with the highest regard for safety. From standard centralized fusing and power distribution to the structural integrity of the unit, ShuttleAIRE systems have you covered.

SLR Rooftop Systems

comfortek SLR hvac bus

The SLR is a one-piece lightweight rooftop unit that has optimal clearance both inside and outside the vehicle. It delivers superior airflow throughout the vehicle due to its centered position compared to rear or front-mounted units and can be configured in multiple ways to deliver the right amount of cooling for the application. Thermo King's exclusive ComforTEK system delivers:

  • Better Air Distribution for More Comfortable Passengers
  • Multi-Directional Airflow Means No Hot or Cold Spots
  • Balanced Performance for Lower Energy Consumption
  • Lower Profile Design for Increased Passenger Headroom
  • 40% Less Refrigerant Required for Cost and Environmental Savings

FEATURE BENEFITS
Through-Roof Design inside bus 20-25% quicker installation Safer work environment - no climbing on roof. Control panel located inside bus (67 kg)
Mechanical Fittings Ease of maintenance
Modular Construction Reduced installation time Eliminates long runs of hoses in bus chassis. Moves condenser from the ground, less maintenance, longer life. 40% less refrigerant charge
Multiple Configurations from One Basic Design Flexibility to configure a system for buses from 14’ to 32’. Flexibility to configure a system for any climate zone.
Injected Structural Foam Construction Lightweight, rustproof and recyclable

Split systems provide complete flexibility to meet the cooling needs for even the most demanding applications. Rooftop or skirt, single system or multiple systems, Thermo King provides solutions for every customer need. These units reflect Thermo King’s commitment to sustainability, efficiency, and reliability while maintaining customer value every step of the way.

Thermo King systems are developed and tested in accordance with the American Society of Heating, Refrigeration, and Air conditioning Engineers (ASHRAE). ASHRAE testing validates the entire system, ensuring performance in all climates vs. ratings determined via the IMACA method, which may only test system components that are not reflective of the installed application.

Leveraging the ASHRAE application philosophy, Thermo King units are designed to deliver the required cooling capacity across the entire engine RPM range. This results in increased passenger comfort, fast recovery, and decreased engine load.
