For decades, the hum of a diesel engine has been the unofficial lullaby of the trucking industry. It’s the sound of a main engine idling through the night, burning expensive fuel just to power the cab’s air conditioning. But that era is over. The future of fleet management is quieter, cleaner, and radically more efficient. It’s time to embrace the revolutionary power of all-electric APU cabin cooling.

For decades, the image of a long-haul truck idling through the night to power air conditioning has been a constant in the logistics landscape.

For decades, fleet profitability and driver comfort have been locked in a costly compromise with the main engine idling.

For decades, the idling diesel engine has been the costly, inefficient, and polluting solution for keeping truck cabins cool during rest periods.

For years, the constant rumble of a diesel APU has been the costly, noisy soundtrack to a driver's rest. The fuel burned, the maintenance headaches, and the environmental toll have been silently eating into your bottom line. That era is over.

The quest for a viable, powerful, and reliable alternative to the traditional diesel-powered Auxiliary Power Unit (APU) has long been a challenge in the commercial trucking industry.

After 2 years of collaborative engineering with American and Canadian experts, Corunclima proudly introduces our breakthrough Electric APU, designed specifically to replace diesel APUs in the US and Mexico markets.

In the demanding world of commercial trucking, where driver comfort and operational efficiency directly impact profitability, the Corunclima High-Capacity Electric APU emerges as a game-changing solution that redefines industry standards.

At the heart of the Corunclima Electric APU lies an exceptionally powerful cooling system capable of delivering 15,000 BTU of climate control power.

Corunclima all-electric APU operates entirely on clean electricity, harnessing power from your truck's batteries to deliver continuous, powerful cooling even when the main engine is completely shut down.
