The HDE infrared asphalt heaters, with their unique patented design, allow continuous, uniform re-heating of the asphalt in place to perform patch repair with a seamless joint, or pre-heating to provide an effective bond between an existing pavement surface and a new asphalt layer. This is especially important to achieve good longitudinal joints and when attempting cold weather paving.The heaters used on the machines are specially designed and patented to provide maximum efficiency and BTU output while providing a large heating area that meets durability requirements for construction use. A primary difference between HDE machines and asphalt heaters is that the HDE equipment operates on Liquid Propane (LP) and is equipped with a vaporizer that turns liquid drawn from the propane tank into vapour. This allows all the propane in the tank to be used without reduction in p ressure (and thereby temperature) during operation. The tanks can be completely emptied without frosting in cold weather saving propane costs and tank change time.
Most important to the contractor, HDE equipment does not require batteries and blowers for operation, simplifying operation while eliminating costly downtime and repair.
The HDE heater can be operated at a range of pressures from 15 psi to 50 psi. This enables the heater to be switched to a low pressure (low heat) during short delays in job progression. This means the heaters don't have to be shut down or left on high heat while raised from the asphalt surface to prevent burning. The result of this pressure decrease is a reduction of propane usage.
The design and flexibility of HDE asphalt heating equipment leads to varied uses in the construction industry.
Heat Design Equipment Inc. continues to research new and beneficial uses of the HDE heater. A tour through our website will demonstrate interesting applications of infrared heat in the construction industry.
