Zero emissions, respect of the environment and comfort for the user

Significant reduction of the noise emissions and the possibility for use in an indoor environment, during the night and near hospitals and schools

Energy saving and significant reduction of operating and maintenance costs

Convenience, comfort, speed and savings

The machine is equipped with the innovative and exclusive patented “Niagara system”, designed to improve comfort and reduce the time and water to clean the hopper.
The movement of the screw pump from working position to cleaning position creates a discharge opening in the hopper and at same time causes the displacement of the screw feeder from the bottom of the hopper facilitating the cleaning of the hopper and the evacuation of the residual products.

Preserving the environment and your wallet

S28 Volta Urban is very economical: only about 1€* for a complete charge maintenance costs cheaper compared to the spraying machine with diesel engine.

Significant reduction of management and maintenance costs

The electric permanent magnet motors, compact and lightweight, are zero pollutants, require little maintenance and are very economical compared to the Diesel engine. The permanent magnet motor is controlled by an electronic controller which ensures a perfect control of the speed and torque of the motor.
Goodbye:

  • engine oil and coolant changes
  • belts
  • filters
  • flexible
  • downtime for the execution

Battery pack with centralized filling system

The battery technology used is the “flooded/wet lead acid” which is proven, widespread and economical.
The estimated lifetime is about 1200 cycles with discharge of about 50% of the rated capacity.
More deeply discharged batteries, more they age rapidly.
To avoid premature wear we strongly advise you not to discharge the battery over 80%.
Water plays a crucial role in the functioning of the battery.
If the water level in the cells drops too low, the plates were then exposed to air. The active elements of the plates dry out and become brittle, which irreversibly damages the battery. The centralized filling system can simultaneously fill all the elements, if necessary.The discharge indicator integrated into the control panel as well as the integrated battery charger allow you to be independent on site.

Applications

  • Spraying pre-mixed plaster
  • Concrete spraying and fibre-reinforced mortar
  • Injections of cement grouting under controlled pressure
  • Pumping mortar and insulation materials

Technical Data
