HYDRAULIC REFRGERATION
Hydraulic generators save money and the environment
Transport refrigeration powered by diesel units can easily be converted to electric power. This is made possible by hydraulic generators that reduce both fuel consumption and environmental impact.
Hydraulic generators are a unique solution that allow an existing diesel powered unit to achieve the same environmental classification as the vehicle. This is done by simply converting the unit to electric power, eliminating the need for diesel. The generator is powered by the vehicle’s PTO, turning the vehicle into a rolling electricity producer. In addition to reducing the vehicle’s total fuel consumption, this also results in fewer carbon dioxide, nitrogen oxide and particle emissions.
Hultstein’s generator solution, Ecogen, can be installed in a few days and produces a 400 V 3-phase voltage whether the vehicle is moving or running idle. Ecogen is able to operate equipment with a power demand up to 25 kW and can be used on all refrigeration units equipped for network operation.
How does Ecogen work?
Ecogen is a truck-driven hydraulic generator powered via the engine drive PTO which can make an otherwise dirty diesel transport refrigeration unit (TRU) into a clean hybrid electric-powered refrigeration unit during transit.
Ecogen has transformed the potential for how we use diesel powered refrigeration units by running the TRU on electric, which is generated by drawing a small amount of power from the Euro 6 or gas engine, while on the road.
Ecogen is built to last 10-12 years and easily swaps from one tractor unit to another.
Naturally if no alternative ‘clean’ options are avaliable, a TRU can continue to operate as a stand-alone system fuelled by diesel.
What’s fitted to the truck to run Ecogen?
The engine requires a permanent engine drive PTO (power take off) to power the Ecogen hydraulic pump. The good news is, if you operate Scania, Volvo or Renault tractor units the timing gear for the PTO is already fitted into the engine.
Alternatively you can purchase a PTO adapter or specify a PTO when purchasing a new tractor unit. All marques of truck offer this permanent- engine drive PTO as an option.
Benefits of running Ecogen:
- Retrofit to all Scania, Volvo or Renault tractor units

- 70%-85% carbon saved*
- 98% saving of diesel particulate matter emissions*
- Lower service costs
- Reduced noise
- Easily transfers to new trucks after 1st life
- 4X N0x Reduction*
* In comparison to running a traditional diesel fridge unit.
