Idle Reduction

Air heaters draw in ambient air, heat it, and blow it throughout the interior of the bus. They provide a fast and efficient way of keeping drivers and passengers comfortable. The Air Top 2000 ST is compact and powerful and perfect for smaller buses, with 7,000 Btu/h. The Air Top Evo 3900 and 5500 are designed for medium and larger buses, with high output and advanced control features including Eco, Boost, and Altitude modes, which allow for more efficient operation.

Air Top 2000 ST: The Air Top 2000 ST is the most popular choice in idle reduction technology by OEM's, owner-operators, fleets and mechanics. Perfect for most class 8 sleeper cabs, the Air Top 2000 ST gets the job done with 7,000 Btu/h of heat output in a small package. Low maintenance, service-friendly and the most efficient air heater on the market, it can pay for itself within months.

Air Top Evo 3900/5500: The next Evolution in heating, the Air Top Evo series offers high output and advanced functionality. When used with the multi-functional controller, the Air Top Evo can be set to boost mode for increased output, altitude mode for performance in higher elevations, and eco mode for reduced fuel consumption. The Air Top Evo 3900 is used in class 8 trucks that operate in extreme conditions or in cargo applications. With the highest output of 18,700 Btu/h, the Air Top Evo 5500 is used in large cargo applications.

Webasto coolant heating systems heat the cold coolant from the engines’ block, then pump it back to the bus’s engine and heat exchangers. The preheated engine starts easily, consumes less fuel, and emits fewer pollutants. Webasto offers the Thermo Top C, Thermo 50, Thermo 90 ST, Thermo 230/300/350, DBW 2010, DBW 2020/300, and Scholastic Heater.

Thermo Top C: The Thermo Top C is used in shuttle and school buses. Just set the timer and let the Thermo Top do the rest. Transportation supervisors are saving hundreds of thousands of dollars by using Thermo Top C's to pre-heat engines before drivers even arrive.

Thermo 50: The small and robust Thermo 50 water heater warms up the cabin interior and the engine to optimal starting temperatures. The stress on the engine through coldstarts is thereby drastically reduced, and the longevity and operational readiness of the engine is substantially increased. Additionally, by operating the parking heater, the environment is spared through the decreased fuel consumption and the CO2 released into the atmosphere by idling.

Thermo 90 ST: The Thermo 90 ST is best used for extreme climates, when it is normally much more difficult to get your engine to start. With 31,000 Btu/h of heat output, the Thermo 90 ST gets the job done even in the harshest conditions. When you choose Webasto instead of idling, you're choosing to save fuel and reduce engine wear, maintenance costs and exhaust emissions.

Thermo 230/300/350: The Thermo 230/300/350, the high-performance water heaters of the Thermo series, heat up large engines up to appropriate operational temperatures before actually starting the engine. The passenger cabins in public-transit busses or coach busses can be warmed after long standing periods to a comfortable temperature level without running the motor.

DBW 2010/2016: Designed to do it all, the DBW 2010 draws in cold engine coolant, then heats it and pumps it back to the vehicle's engine and HVAC system. The result is a pre-heated engine and warm interior. In extreme climates, you can also use the DBW 2010 with additional accessories to warm the fuel and keep it from gelling.

DBW 2020/300: Available in 12 and 24 Volt models, the DBW 2020 and 300 make engine pre-heat and interior heat look easy. The heaters boast 80,000 and 104,000 Btu/h of output, so they are used mainly for large transit buses and motorcoaches.

Scholastic Heater: Designed especially for school buses, the Scholastic Heater warms the engine, the driver and the students, and makes sure that school bus fleets are running safely and efficiently, even on the worst winter days. You can count on the Scholastic Heater to reduce idling, save fuel, defrost and defog windows, increase driver retention, provide supplemental interior heat, and reduce maintenance costs.

Webasto brings state-of-the-art technology from conception to reality with the BlueCool , pioneering the use of cold energy storage in the global truck market. The two models are the BlueCool and BlueCool Hybrid, both featuring efficient storage technology and setting them apart from competition. The BlueCool charges while the truck is operating and then is available for engine-off bunk cooling during rest periods. The BlueCool Hybrid features a shore power connection that plugs into any 120V outlet to charge the system and provide hotel load in the cabin.

BlueCool: BlueCool features a cold storage unit that mounts to the frame rail and an air handler that mounts to the back wall inside the cab. While the truck is operating, the alternator generates 12V DC power that is inverted to 110V AC by a power inverter. This drives a refrigeration compressor which freezes water retained in the patented cold storage graphite matrix mounted to the frame rail.
The BlueCool system is now charged and ready to cool the bunk. After the engine is turned off and the BlueCool temperature and fan speed controls are set, a chilled coolant mixture is circulated through the storage core by way of a high-efficiency pump and then transferred between the air handler in the cab and the cold storage unit. The air handler draws in warm air from the bunk and cools it with the chilled coolant circulating in the heat exchanger. The cooled air is returned to the bunk through four adjustable openings in the air handler. The result is a comfortable bunk during rest periods and hundred of dollars saved per month.

BlueCool Hybrid: The BlueCool Hybrid operates similarly to the standard BlueCool when it's not plugged-in, offering bunk cooling on-demand. But, when a 120V outlet is available BlueCool Hybrid can be plugged-in and be charged and discharged simultaneously. This means the user can cool his bunk indefinitely without losing cooling performance.
In addition, two 20-Amp receptacles are available for hotel load, allowing the driver to use virtually any 120V appliance without worrying about running down the vehicle’s battery. With the BlueCool Hybrid, the driver can remain comfortable during extended stays and have access to all the creature comforts of home without needing to run a generator or use a Diesel Powered APU.
