Give your customers increased starting reliability and equipment uptime with the new 24-Volt Engine Start Module
from Maxwell. Whether you build or maintain buses, bulldozers, off-road trucks, agricultural equipment, cranes, graders,
pavers, feller-bunchers, or portable compressors, we’ve got you covered with the high current 24-Volt cranking capacity
your customers need. Effectively eliminate jump-starts, lost productivity, drivers/operators on standby time, and equipment
downtime due to weak batteries.
Don’t leave starting to batteries. One Maxwell 24-Volt ESM takes over all engine cranking for engines up to 15 liters. And it
provides high speed cranking from -40°F to +149°F (-40°C to +65°C), all the time, every time for hundreds of thousands of
starts.*
