What is the Cabin Comfort?
The simplest way to
stop idling
your sleeper cab.
Think of it as climate control for your sleeper cab, powered by a dedicated battery pack — not by the diesel engine. When you park for the night, the engine shuts off and the Cabin Comfort keeps you warm in winter, cool in summer and breathing clean air. No idling. No fines. No engine wear.

Maintenance-Free Reliability
Unlike a small second diesel engine or a generic battery box, the Cabin Comfort is virtually maintenance-free. Designed for longevity and reliability — enjoy hassle-free operation and optimal performance without frequent service stops.
Fuel & Mechanical Savings
Efficiency that pays off. Save 1 gallon of diesel per hour when the truck is not in motion — an average $750–$1,000 monthly savings. By reducing engine idling you also prevent costly wear and tear, significantly lowering maintenance expenses.
Environmental benefits & regulatory compliance
Cleaner air.
No costly fines.
The Cabin Comfort helps reduce emissions of harmful pollutants like carbon monoxide, nitrogen oxides and particulate matter. By reducing idle time, it cuts carbon dioxide emissions by up to 550 pounds per year for every hour of idling reduced, contributing to cleaner air and public health.
The Cabin Comfort helps fleets comply with strict state and federal idling regulations, such as California’s rule limiting idling to no more than five minutes, with fines of $300 per violation. It also supports compliance with DOT, EPA, FMCSA and NHTSA regulations.
