On-Highway Trucking Products

PHP parking heaters are the perfect partner for that long-haul route. Our eco-friendly diesel-fueled air heaters work independently from the engine, meaning you don’t have to keep your truck running through the coldest nights just to stay warm. Plus, our ultra-efficient water/coolant heaters can bring the cabin and engine up to optimal temperatures before starting your rig, giving you a more comfortable start to your day and fewer headaches down the road. DKSI also offers a wide variety of Genuine OEM & Aftermarket heaters & replacement parts for Espar, Webasto, Snugger, and Fleetrite brand heaters.
