Features
LISA app as control system
The LISA app offers quick, cable-free control of 12 V spreaders via your mobile device. Simply scan the QR code to connect and manage all settings, including spreading width, flow rate, and AUTO-DOSIS. Features include empty hopper alerts, day/night mode, acoustic and visual warnings, boost, area counters, and four memory buttons. The app supports secure Wi-Fi connection, multi-spreader control, automatic language translation, and customizable alerts and driving modes.
VA agitator made of stainless steel
The patented LEHNER agitator system guarantees that the pourable grit continues to run.
Electronic Dosing
The application rate of the POLARO ® E is also set on the control unit. Speed-dependent dosing via the AUTO-DOSIS control offers even more convenience.
AUTO-DOSIS via GPS in LISA app
AUTO-DOSIS automatically adjusts the valve position in line with the driving speed.
After you have selected the material, entered the desired spreading width and quantity per m², the AUTO-DOSIS automatically reacts to driving conditions and controls the dosing valve accordingly. The desired discharge quantity per m² remains constant.
AUTO-DOSIS via GPS receiver in LISA
The speed is determined by GPS and forwarded to the control panel.
