Rethinking Thermal Management with the CM-Series CTMS: From Components to Systems

CTMS CM1 and CM2

If you’ve worked on electrified platforms, you’ll already know this: thermal management has quietly become one of the most complex parts of the application. It’s no longer just about keeping a battery within a safe temperature range, or ensuring the cabin stays comfortable. You’re now dealing with multiple thermal loads (hydrogen fuel cells, battery packs, […]

Electric Buses: 5 Winter Maintenance Top Tips To Keep Your Fleets On The Road

Bus in the winter

Operating bus and coach fleets is a complex task. You need to be able to balance reliability, comfort, and safety for passengers in all conditions. Maintenance sits at the heart of this, helping to ensure vehicles and their HVAC systems operate efficiently throughout the year. During the winter months, this becomes even more critical. Falling […]
