Designed specifically for truck fleets, Corunclima’s Back Wall Air Conditioners deliver powerful, independent cooling directly to the sleeper berth—no main engine required. For drivers who spend more nights on the road than in their own homes, this means a quiet, comfortable rest environment that’s not dependent on idling. In an industry where talent is scarce, offering a better rest experience isn’t just a nice-to-have; it’s a critical tool to attract and keep top drivers, reducing turnover costs and building a more reliable team.

Corunclima’s Back Wall Air Conditioners eliminate this waste, slashing fuel costs dramatically and boosting your fleet’s bottom line. But the savings don’t stop there: reducing engine idling also cuts down on wear and tear, extending the lifespan of your trucks and minimizing costly maintenance downtime. More uptime means more deliveries, more revenue, and less stress—exactly what fleet managers need to stay ahead in a competitive market.
With increasingly strict emissions regulations across regions, fleets that fail to adapt risk fines and reputational damage. We have more than 10 years' experience in electric air conditioner, and have alrealy helped our partners successfully expanded their business and got more market share.
