Sleep Cool.

Stop Idling.

Drive Safer.

Coolabah's cab AC units run all night on battery power - no engine, no fuel, no noise.

Two models, purpose-built for single vehicle operators.

THE PROBLEM

Idling Your Engine to Stay Cool Is Costing You More Than You Think

Every night you idle your engine to run the cab A/C, you're burning fuel, adding engine hours, and breathing exhaust fumes. It's a problem every owner-driver knows — but most accept as unavoidable.

Stop Fuel Costs Eating Your Profits

Based on current diesel prices, idling for an average of 8 hours, 7 nights a week, can add more than $6,200 annually in fuel alone — just to stay cool.*

More idling means more service

Every hour of idle time on a diesel engine adds wear and increases service needs. Coolabah eliminates idle hours entirely — your engine only runs when you're driving.

Less Noise Means Better Rest

A running engine means noise, vibration, and exhaust fumes in your sleeping space. Coolabah is whisper-quiet — so you actually rest.

Heat and Fatigue Is A Safety Risk

Cab temperatures above 28°C significantly impair sleep quality and next-day alertness. For long-haul operators, that's a serious safety issue..
