Working by burning diesel to heat the air inside the cabin, diesel air heaters can preheat the interior even when the engine is off, maintaining a warm temperature for a comfortable driving experience in cold conditions. This is particularly important for those spending extended periods in their vehicle, allowing you to turn off the engine while maintaining cabin warmth through the heat produced by the diesel air heater.

Cab Heaters

Cab heaters utilize the heat generated by the engine, transferring it through the cooling system's flow of coolant into the cabin, thereby raising the interior temperature. This means the engine must be working and reach a certain temperature before the cab heater can function. Not only do they enhance driving comfort, but they also reduce distractions caused by the cold, improving driving safety.
