1 1 ECO Seam Easy, compact and seamless asphalt paving, with an effective ceramic infra red heater

2 2 A vulnerable part of any asphalt paving project is the longitudinal seams, which occur when the asphalt layers are constructed in multiple lanes. In the range of these longitudinal seams, where hot asphalt is placed along cold asphalt, quality losses such as grain breakout or cracks are inevitable. The ceramic asphalt seam heater ECOSeam constitutes the ultimate solution to this problem. By heating the seam with an appropriate amount of energy by means of infrared radiation, the cold asphalt becomes sufficiently heated. In this way, the transition on the seam between hot and cold asphalt will become compact enough so that no seam will be visible later on. Within the framework of a development project dating several years back, ECO Clean Tech, in cooperation with Ooms Avenhorn Groep (specialists in civil engineering projects in the Netherlands) and TipSpit, has developed and patented a unique system for heating longitudinal seams. Asphalt without an ECO Seam heater Asphalt with an ECO Seam heater The basis for this efficient heating system is a ceramic foam burner. This burner generates a large amount of high temperature infrared radiation at a low level of gas consumption. The wavelength of this infrared radiation is such that it is well absorbed by all types of asphalt. The key advantage of this energy source is that the heat penetrates deep into the asphalt base - even at full production speed of the paving machine - without burning the bitumen.

3 3 Use of the ECOSeam greatly improves the quality of the longitudinal seams in asphalt construction. The heating system can easily be mounted by means of a lightweight aluminum support on the spreader beam of a paving machine. This aluminum support is designed in such a way that it neither damages the beam nor reduces its efficiency. In addition, the ECO Seam system is constructed to follow every maneuver of the paving machine. The heater system will switch on and off automatically when the paving machine starts and stops. Characteristics / Features Immediate heat progression without contact with a flame Even and steady distribution and good penetration of the heat No burning of bitumen Can easily be assembled by two people (40 kg) Secure heating with low gas consumption (6 kg of propane gas per hour), also for liquid gas (car gas) Switches on and off automatically by coupling to the paving machine Lightweight aluminum support (optional) Can easily be transported in a heavy duty case (optional). Ceramic heating The system consists of the following components: Infrared heater 80 kw Switch cabinet with automatic ignition and flame supervision Control cabinet Electric connection 24 V, 8 A or 12 V, 8 A Lightweight aluminum support (optional) Heavy duty transport case (optional)

4 4 Assembly instructions for the ECO Seam With four easy steps, the infrared heater can be mounted on the paving machine by means of a lightweight aluminum support. Simply two assembly supports have to be welded onto the spreader beam of a paving machine. The paving machine has to be modified so that it will be possible to switch the burner on and off automatically. The two necessary gas containers can be deposited on top of the machine. Step 1: Assembly of the first part of the aluminum support on the beam Step 2: Assembly of the second part of the aluminum support with mounting points for the heater Step 3: Mounting of the heater on the support by means of adjustable chains Step 4: Mounting of the control cabinet on the heater and connection to the electricity and gas

5 5 Step 1: Connect the two ECO Seams to the suspension arm as mentioned in the user manual. Step 2: Lift the structure with the suspension arm. Remove the safety pins and the supports. Step 3 You can use the two ECO Seams fixed by the two distance holder.
