Idling has a price Webasto’s comfort solutions enable operators to cut costs and efficiently maintain

comfort while their machine is off. Machine operators no longer need to idle equipment to maintain engine heat, reduce fuel gelling and keep cabs warm. Operating engines at a low speed (idling) causes twice the wear on internal parts, which increases maintenance costs and can even shorten the life of the engine over time. Shown above - idling can raise expenses by up to 17%. Idling causes unnecessary fuel consumption and increases machine working hours, both impacting the maintenance cycle as well as machine warranties.

Engine-Off Cabin Cooling Technology

Polar Cab ES Machinery and operators are expected to work under the harshest conditions. Webasto offers an innovative solution for on-demand engine-off cabin cooling. Operators can turn off engines to reduce emissions, fuel costs, and maintenance costs while remaining cool and comfortable during wait/load times.

Polar Cab ES

Air Handler Polar Cab ES is designed to fit onto a variety of machine sizes. Webasto offers two cabin air-handler options: The Osaka is a floor mounted air handler. The Oakland is a vertical over-head mounted air handler.

Compressor/Condenser Unit with evaporator The Polar Cab ES is a battery driven electric cabin cooling system. When the engine is off, the Polar Cab ES can then be turned on (during wait/load time) to keep cabin temperatures cool and comfortable.

Coolant Heaters A Webasto coolant heater 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, the heater can be used with additional accessories to warm the fuel, hydraulic fluid, and batteries. Pre-heating engines significantly improves DPF performance.

Features & Benefits: n Provides engine pre-heat & interior cab heat n Saves fuel and eliminates cold starts n Increases productivity & extends hours of operation n Reduces engine hours, wear and maintenance costs n Increase productivity n Reduce DPF’s & improves DPF performance

Independant Emissions Testing Lab (IETL)* result verification on the effect of a Webasto pre-heater on the emissions performance of a diesel engine. PM Emissions & DPF Performance

Results Summary

1. Engine start-up temperature has a huge impact on the emissions levels emitted by the engine

2. The test results show a 29% reduction in CO during winter conditions, and a 62% reduction during normal ambient conditions.

3. Pre-heating the engine does not have a significant effect on the Hydrocarbon emissions.

4. NO x emissions were reduced by around 40% by pre-heting the engine to 155 ° F.

5. PM emissions have a significant effect and were reduced by 66% by pre-heating the engine during the cold weather conditions. Pre-heating also provided a 27% reduction in PM emissions during normal ambient conditions. This will help in longevity of the DPF life and can avoid more frequent regenerations and cleaning intervals.

3. With Engine-Off Heating technology – Longer stop: If the engine continues to cool down, the webasto coolant heater also switches on automatically. The temperature of the engine and cabin remain stable.

4. Without Engine-Off Heating technology – Engine off: When the engine is switched off, heat is no longer distributed to the cabin interior through circulating coolant. The thermal energy stored in the engine is lost; the cabin interior and engine cool down.

2. With Engine-Off Heating technology – Quick stop: Residual heat in the engine is used by the heater, as the Webasto circulation pump keeps residual heat moving through the cooling system. The temperature in the cabin interior remains stable.

1. Engine running: The engine generates heat, which is circulated via the heater core.

DPF Solutions for the Off-Highway Market

n Up to 66% reduction in PM during startup n Up to 40% reduction in NOX n Up to 62% reduction in CO during startup based on ambient temperature n Increases exhaust temps rapidly, aiding in catalyst activity n Emission reduction at high ambient temperature n Emission benefit to pre-heat year round Independent testing shows that using a Webasto coolant heater to pre-heat an engine can significantly improve DPF performance.

How to extend the life of DPFs Diesel particulate filters are necessary to adhere to existing and future emission regulations. But they’re also an additional expense. When an engine is idling, the combustion temperature is too low for the DPF to run efficiently. The system has to be cleaned more frequently and parts wear more quickly. Automated Engine-Off heating therefore also helps extend the life of particulate filters.
