Peterbilt has announced that its no-idle fuel-fired heater is now available for Model 579s and 567s equipped with 44-inch sleepers.

With these latest additions, the system can be spec’d with the full range of Peterbilt sleepers including the 44-, 58-, 72- and 80-inch versions.

The self-contained system requires no plug-in energy sources and is complemented by a Low Voltage Disconnect that preserves battery life to maintain enough starting power. The LVD automatically disconnects non-vital battery loads and will automatically reconnect loads when batteries reach sufficient charge.

The fuel-fired sleeper heater system includes an under-bunk heater, fan-powered circulation and a digital control panel that is mounted in the sleeper.
