HDE manufactures patented infrared heaters and heating equipment for large scale efficient heating. Largest market is in asphalt pavement construction and repair. We manufacture in house as well as outsource fabrication of our equipment using our own CAD designs to ensure top quality and fast delivery of this unique equipment. JOINT HEATER Our joint heater is used to reheat the longitudinal edge while paving to prevent low compaction and water permeability and early deterioration to potholes. This is one of the most prominent paving problems today. HEATER PATCHERS: These units can be used to reheat deteriorated asphalt in place, scarify the cracked areas, add a bit if new asphalt and recompact to form a seamless patch. This is 100% recycling in 20 minutes! ASPHALT RECYCLERS: Can reheat chunks of waste asphalt in ten minutes in the winter time to make hot mix asphalt for pothole repair. Makes a permanent repair instead of just filling a whole with new cold mix that tends to fall out in a matter of days. OTHER POTENTIALS: Preheating oil sand material instead of using steam and hot water. : Pre-heating water for steam heating in autoclaves. :Weed killing
