Clean, quiet, efficient: electrified cooling units
New solutions are needed to reduce noise and pollutant emissions in cooling distribution systems.Together with our partner AddVolt we equip new and used vehicles, vans or trucks in such a way that conventional cooling units can be operated permanently, i.e. even while driving, via the electric mode.
The systems presented here are independent of the vehicle and the cooling unit. They can be retrofitted as plug-in solutions and provide full performance, even for the transport of frozen goods.
Drive and stationary cooling via electric mode - The advantages:
- clean and quiet in the city centre, the electrical operation reduces the noise by approx. 6.5 dB24/7 access to the city centre
- Electric operation is permitted everywhere, even on ferries and in underground garages
- no noisy diesel engine during delivery and during driver rest periods
- Energy/fuel costs are reduced
- Optional recuperation makes operation even more economical on overland tours.

Electrified diesel refrigerating machine for trucks
- powerful powerpack
- Electric drive in driving and stationary mode - Diesel engine becomes obsolete
- economical operation through recuperation
No CO2 - and no fine dust pollution - the clean distribution of refrigerated goods in city centres is possible with this innovative solution.
Protected system - patent pending!

For power take-off units in the van class:
Full power independent of engine and speed
Cooling machines which are not operated by their own diesel engine but by a power take-off of the vehicle require high speeds for the required full cooling power. Cooling units can reach their limits here, depending on the area of application, kilometres driven, distance travelled and outside temperature.Cooling mode via the electric mode of the cooling unit ensures constant cooling performance.
The energy for this comes from the AddVolt Powerpack, which is fed from the mains overnight or while the vehicle is stationary.
As a plug-in solution, the system is completely independent of the vehicle engine and thus also independent of the start-stop systems of the vehicle engines. Virtually any cooling unit can be operated.
The power pack of the vehicle in the picture is housed in the vehicle frame.

Monitoring via My AddVolt makes the economic operation visible!
The clear login area for all users enables GPS tracking of equipped vehicles and precise monitoring of tours and refrigerator data:- Number of operating hours in electric mode and via diesel engine
