New NSS CHARGER 2022DB 20" Walk-Behind Burnisher - 220Ah AGM Battery
Our Take (from the SES Sales Team)
“The Charger 2022 DB is a good fit for buildings that burnish often and want to get away from propane: schools, grocery and retail stores, hospitals and office lobbies. It spins a 20 in pad at 2,200 rpm with 70 lb of pad pressure, and NSS rates it at 24,000 sq ft per hour. The DB stands for drive, and that matters on a machine this size. A twist-grip throttle runs a drive motor, so the operator steers instead of pushing a 720 lb burnisher across the building. This package runs on six 220 Ah AGM batteries rated for up to 2.7 hours, with no battery watering, and the charger is on board. With no engine there are no fumes, no oil changes and no tanks to swap, and at 68 dBA it is quiet enough for occupied buildings. The Vac-Trac dust control captures the finish powder burnishing creates. If your runs are long, NSS also offers a ride-behind sulky for it.”
A 20 in wheel-drive battery burnisher with no propane to manage
The NSS Charger 2022 DB is a 20 in battery burnisher that restores the wet-look gloss of floor finish without propane fumes or exhaust. A 2.5 hp, 36 V pad motor spins the pad at 2,200 rpm with 70 lb of pad pressure, a wheel drive with a twist-grip throttle moves the machine, and NSS rates it at 24,000 sq ft per hour.
This configuration runs on six 6 V, 220 Ah AGM batteries, sealed and maintenance free, rated by NSS for up to 2.7 hours. The onboard charger plugs in at any standard outlet.
