The infrared effect is created by premixed gas and air delivered under pressure to a series of energy converters. Infrared does not flame or negatively alter the binding characteristics of asphalt. Each Heater Unit contains a 15- by 144-inch heating chamber which is designed to be operated in a horizontal position, and which will have a maximum consumption of 20 pounds of propane per hour for each heater. An infrared optical sensor ensures accurate temperature control with a minimum of maintenance. On both paver mounted heater and pre-heaters, the automatic setting keeps the heater on as long as the temperature of the asphalt is less than the predetermined sensor setting.
The thirty-six inch energy converters are constructed of 16-gauge stainless steel for long production life. The nickel alloy grids that produce the infrared rays are located in the centre of the converters. These rays are directed to the pavement through the use of stainless steel reflectors. The pre-heaters are powered by a 115-Volt AC, propane-powered generator. Generators are not included with the paver-mounted heater, which takes power off the paver.
Searching for the best-performing excavator? Your search ends here. We tested the Volvo EC350E and EC380E against a leading competitor in three different tests: trenching, truck loading and lifting capacity at reach. The results show a 20% difference in cost-per-ton, a 15% difference in tons-per-hour and a 12% difference in both operating costs and lifting capacity. See the results and put an end to your search for the best excavator.
