Successful case of Idle free electric apu




Developed to solve the persistent challenges of soaring fuel expenses, loud diesel generators and inadequate driver comfort, Corunclima’s Electric APU represents the future of modern trucking technology.
Engineered to perform in the toughest operating conditions, the Corunclima Electric APU features a market-leading 15,000 BTU cooling capacity. It delivers consistent, high-powered cooling that keeps drivers fully comfortable, even when outdoor temperatures climb above 120°F. This exceptional performance ensures reliable operation in extreme heat. Unlike noisy diesel generators that disrupt rest with constant rumble and vibration, this electric APU operates silently, creating a peaceful cabin environment where drivers can recharge fully, enhancing alertness and safety on the road.
This electric APU brings four core advantages that transform fleet operations. First, it achieves zero idling and zero emissions, completely eliminating diesel consumption during rest periods and reducing the carbon footprint of trucks, aligning fleets with global eco-friendly standards and increasingly strict emissions regulations. Second, it generates massive fuel savings, preventing 0.8 to 1.5 gallons of fuel from being burned per hour of idling—savings that add up to thousands of dollars annually per vehicle, directly boosting fleet profitability. Third, it offers unrivaled extreme cooling performance, maintaining a cool, quiet and vibration-free cabin environment that drastically improves driver rest quality. Fourth, it is built for exceptional durability, equipped with an integrated DC compressor and boasting a service life of up to 10 years, standing up to the rigors of heavy-duty long-haul travel.
