Umeå, Sweden: Mångbergs Åkeri’s latest Scania V8 uses a Frigoblock electric FK25 fridge with an alternator capable of also powering the additional refrigerated trailer creating a hybrid road train.
This latest project, part of Mångbergs Åkeri’s move to eletrification of the fleet, uses the Frigoblock alternator to power the truck-mounted FK25 unit and the Thermo King SLXi on the trailer.
“Our operations require powerful trucks and efficient refrigeration systems that can not only work in long-haul, sometimes extreme conditions, but that also represent our approach to sustainability” said Stefan Mångberg, owner, Mångbergs Åkeri.
Björn Forsberg, account manager, Frigoblock, said: “With Mångbergs Åkeri, we tailored our technology to meet their requirements and create not only the first Scania truck with a V8 engine and an electric Frigoblock refrigeration system, but a compelling solution also allowing us to power the drawbar trailer’s refrigeration.”
The newest Scania truck in Mångbergs Åkeri’s fleet, together with the drawbar-trailer, creates an almost 24 meter long road train. Running on HVO-biofuel, the truck operates on routes of approximately 600 kilometres a day, seven days a week. Frigoblock was asked to deliver a refrigeration system that would convey enough cooling capacity for both truck and trailer, while running on electricity.
Frigoblock opted for the FK25 unit for the truck. To make it work with the Scania’s V8 engine, and maximise the engine’s power, the team installed a new hydraulic driven alternator kit. The hydraulic drive kit provides enough power from the Scania’s V8 engine to power the electric FK25 unit but also the Thermo King SLXi trailer fridge. This allows Mångbergs Åkeri to run the refrigeration units on electricity immediately when the truck is running and benefit from a fully electric-refrigerated truck and a hybrid trailer road train.
Frigoblock’s refrigeration has also met the stringent requirements related to air circulation inside the truck. The load compartment is divided in two by hydraulic floors and requires the refrigeration unit to deliver enough capacity to evenly circulate air and ensure the same temperature level across the space, in all ambient conditions.
“We are moving away from diesel-powered refrigeration and have tested different refrigeration technologies in our drawbar applications.” Mångberg said. Frigoblock’s alternator technology generates so much power that we practically don’t need to turn the trailer refrigeration unit’s diesel-engine. This really helps us to make our operations greener and supports our move towards low-emission distribution and logistics.”
