## Hear from our customers
> Our Kenworth Road Train fleet is equipped with Coolabah bunk air conditioning in the cabs. Regardless of the outside temperature, the Coolabah system maintains a comfortable and consistent cabin environment, and the energy efficiency means we don't have to worry about excessive power usage.
Mineral Resources
> WFM switched to Coolabah in 2020 and has since saved over $4,000 per truck on fuel and maintenance. While some drivers were initially hesitant, the quieter yard and the convenience of pulling up at any truck stop quickly won them over. Today, many of our drivers are among Coolabah’s strongest advocates.

## Frequently asked questions
What is a Coolabah?
A Coolabah truck sleeper cab cooling & heating system is a climate control solution designed for truck sleeper cabs, ensuring drivers remain comfortable during rest breaks without running the engine or a noisy diesel generator. These systems provide efficient cooling and heating, reducing fuel consumption and emissions.
How does a Coolabah sleeper cab A/C system work?
Coolabah's truck sleeper cab A/C system operates independently of the truck batteries to ensure longer run-time and removes the need to idle the engine. In most cases, the system tries to cool the sleeper cab only to maximise the run-time and reduce heat dissipation. The Coolabah batteries recharge as you drive.
Why should I invest in a Coolabah truck air conditioner?
Investing in a Coolabah truck bunk cooler system saves fuel, reduces engine wear, minimises idling time and enhances driver comfort and well-being, leading to better productivity on the road.
A Coolabah is especially energy-efficient, reducing operational and maintenance costs significantly compared to traditional diesel powered systems. This saves fleets on average over $4,500 per truck per year!
