What is ESB?

ESB means ‘Electric Standby’, also known as ‘Plug-In Power’ or simply, ‘Standby’.

For many years, Diesel power was the driving force behind Refrigerated Vehicles, propelling them while simultaneously operating the Refrigeration Unit. Although this approach was effective, the separation of these two functions through the integration of an electric or hybrid cooling systems brings about significant flexibility and cost savings. To explore the advantages of utilising an Electric Standby, consider the following points:

Continuous Cooling While Stationary

Standby systems power the Compressor, Condenser Fans and Evaporator Fans, even when the truck’s engine is not running. The primary advantage is that drivers can keep their cargo cool without the need to keep the engine running continuously. This feature makes pit stops more convenient for drivers, as they can rest or address issues without concerns about their cargo’s condition. Furthermore, when stationary, the truck operates more quietly, creating a more pleasant environment for the driver.

Performance

Off-Engine Drive (OED) is when the compressor is mounted directly to the engine. This means the compressor speed is dictated by the RPMs of the Engine. When sat at idle, the RPMs of the engine result in the refrigeration compressor running at a reduced speed and therefore, reduced cooling capability. When switched to Standby, the unit can draw an increased and more consistent power, resulting in an increased efficiency.

Reduced Fuel Consumption and Emissions

Arguably, the most significant benefit of employing a Standby system in refrigerated trucks is the potentially substantial fuel savings and Emission reductions. Electricity can be a more cost-effective option, compared to Diesel fuel, resulting in cost savings every time the system is used. This also means fewer refuelling stops for the drivers, saving them time and effort.

Environmental

Using less diesel fuel contributes to a reduction in overall emissions. By implementing Standby systems, companies open up new avenues for pursuing sustainability. Additionally, some states have stringent emission regulations that can be met more easily with the use of electric standby technology.

Truck Life

By reducing fuel consumption and running the engine only when necessary, the overall engine hours are reduced and the lifespan of the truck is extended. This leads to less wear and tear on components, resulting in prolonged maintenance intervals. The end result of having a Standby system in place is a more reliable asset. This not only streamlines operations but also generates cost savings.
