Plaster spraying machine S28 Urban Volta

for mortarconcretescrew

Overview
The first ecological plastering machine on the world market designed for professional use. Battery-powered operation reduces local emissions and enables quieter, cleaner work environments.

Key benefits

• Zero emissions: electric battery operation eliminates local exhaust pollutants.
• Noise reduction: low noise levels allow indoor or night use and work near sensitive locations such as hospitals and schools.
• Energy saving & lower running costs: electric permanent-magnet motors are energy-efficient, require minimal maintenance and avoid diesel service items (oil, coolant, belts, filters).
• Convenience & cleaning: patented Niagara System facilitates hopper emptying and reduces water and time required for cleaning by shifting the screw pump to a cleaning position to create a discharge opening and displace the screw feeder.
• Autonomy & battery management: integrated discharge indicator, integrated battery charger and centralized filling system for flooded/wet lead acid batteries.

Description
The S28 Urban Volta is manufactured in compliance with European directives and is engineered for professional plasterers. Precisely dimensioned power and continuous output control of the screw pump (from zero to maximum) allow pumping and spraying of traditional and special mortars. The unit includes an integrated pressure washer and a dust attenuator as standard to improve autonomy and maintain cleaner operation. The chassis is mounted on an elastic axle for stability on road and site. Reduced weight (746 kg, under 750 kg) facilitates transport and installation in restricted locations.

Applications

• Spraying pre-mixed plaster
• Concrete spraying and fibre-reinforced mortar
• Cement grouting injections under controlled pressure
• Pumping mortar and insulation materials

Included features / standard equipment

• Integrated high-pressure cleaner for autonomous rapid cleaning.
• Dust attenuator with nozzles to nebulize mixing water and reduce dust during bag cutting.
• Niagara System (patented) to simplify hopper emptying and cleaning.
• Battery pack with centralized filling system and discharge indicator; integrated battery charger.

Economy
S28 Urban Volta is economical to operate: approximately 1€ per full charge (actual cost depends on electricity tariff). Maintenance costs are lower compared with diesel-powered spraying machines.
