For years, diesel APUs have been the go-to choice for reducing idling, offering fuel savings and lower engine maintenance costs. Yet many fleet owners have hesitated to make the switch to electric APUs, held back by industry-wide pain points: underpowered cooling that can’t match diesel performance, and runtimes of just 7–9 hours that leave drivers sweating through the night. Corunclima heard these frustrations and engineered a solution that doesn’t just meet diesel standards—it exceeds them.

The Corunclima K50BS Electric APU is a game-changer, designed to deliver the cooling power and reliability of a diesel APU without the emissions, noise, or ongoing fuel costs. Boasting a 15,000 BTU cooling capacity, it matches the performance of traditional diesel systems, maintaining a cabin temperature of 70–73°F even when outdoor temperatures soar to 115–118°F. What’s more, its lithium battery technology provides a runtime of 10–16 hours—far longer than the industry average—ensuring drivers stay comfortable throughout their rest periods, no matter how long they stop.

Unlike other electric APUs that risk draining your truck’s main battery, the K50BS runs on its own dedicated lithium battery pack. This means you never have to worry about a dead main battery delaying your next trip or leaving a driver stranded. As the first company to pioneer lithium battery integration in electric APUs, Corunclima has prioritized efficiency and independence, creating a system that works with your fleet, not against it.

But the K50BS is more than just a cooling unit—it’s an investment in driver well-being. For long-haul drivers, a comfortable, reliable sleep environment directly impacts driver alertness, safety, and retention—critical factors for any fleet looking to reduce turnover and improve performance. With the K50BS, you’re not just cutting costs; you’re showing your drivers that their comfort matters.

Beyond driver satisfaction, the K50BS helps your fleet stay ahead of environmental regulations. By eliminating idling, you’ll drastically reduce CO2 emissions and noise pollution, aligning your operations with sustainability goals and avoiding costly fines for non-compliance. The system’s durable, road-tested design ensures it delivers consistent performance season after season, making it a cost-effective upgrade that pays for itself in fuel savings and reduced engine wear.
