In 1976, Heat Design Equipment manufactured infrared asphalt heating equipment for asphalt pavement patching, longitudinal joint heating for durable joints and pre-heating for cold weather paving, as well as asphalt recyclers and hot box storage containers. Infrared heaters, provide high intensity, penetrating radiant heat into asphalt in place, without burning the surface.
To change the way the world constructs and maintains asphalt infrastructure utilizing infrared technology for longer lasting pavements.
The HDE patented design, allows continuous, uniform re-heating of the asphalt in place, to perform quick asphalt patch repair with a seamless joint, or pre-heating to allow re-compaction and an effective bond between an existing pavement surface and a new asphalt layer.
Heat Design Equipment Inc. manufactures infrared heaters for asphalt construction and repair, using patented, state of the art technology.
The HDE patented heaters are unique from other infrared heaters, consisting of a 16-gauge heater plenum, a patented replaceable heater cartridge, and a protective 16-gauge skirt. Heater panels are made up of any number of interconnected 4-foot (1.2m) or 3 ft (900 mm) long by 18 inch (450 mm) individual HDE heaters. The heater cartridge will develop surface temperatures of 1400-1500 F emitting high intensity radiant heat over a large area. Cartridge life is generally considered to be about 1500 to 2000 hours, which translates to a cost of about 7-8 cents per square foot per hour. At a charge out of $5.00/ SF for repair and figuring 3 heats per hour, the replacement cost of cartridges is about 1/2 % of revenue generated.
