Hot melt furnace
3.1	Volume	100l
3.2	Tank structure	Double layer high insulation structure, insulation layer thickness of 100mm, equipped with safety device and thermal oil sleeve
3.3	Ignition method	Electronic ignition
3.4	Size of feeding port	410mmx320mm，
3.5	Heating method	Using a diesel burner to heat the heat transfer oil and indirectly heating the material, the heating is uniform and the material is not prone to aging
3.6	Material pump	400w, speed 1450r/min, external automatic constant temperature electric heating material pump, safety valve full cycle output, faster and more uniform heating, greatly reducing initial heating time and improving efficiency.
3.7	Flow	The maximum output flow rate is 8-15 liters/minute, and the throttle valve on the valve group can be adjusted.
Heater
4.1	Heating method	Using a diesel burner to heat the heat transfer oil indirectly to heat the material, the heating is uniform and the material is not prone to aging.
4.2	Heating time	30 minutes
4.3	Italian Riyalo burner	Power: (100000kcal/h)
4.4	Electric insulation heating	The utility interface (220V) power supply provides insulation for materials during non construction hours (at night), saving fuel and waiting time before construction. (Requires mains power function, needs to be informed in advance)
4.5	Energy saving constant temperature heating	By automatic program control, when the heating temperature reaches the set temperature, the engine will automatically shut down and enter the insulation state; When the temperature inside the hot melt kettle drops below the set temperature, automatic ignition enters the heating state. Ensure that the hot melt material is always within the safe heating temperature range of constant temperature.
4.6	Heat transfer oil capacity	30L
4.7	Temperature range	50-260 ℃, please refer to the instruction manual for recommended temperature. It needs to be flexibly set according to the actual situation.
4.8	Control mode	Sla-5000 intelligent digital temperature controller, with constant temperature control throughout the entire process.
4.9	Temperature display	Monitor the temperature of thermal oil, joint filling materials, and electric heating hoses, and automatically control them with a computer (automatically insulation when reaching the construction temperature)
Mixing
5.1	Mixing method	Mixing adopts electric stirring, intermittent stirring, vertical axis 360 degree bidirectional stirring, uniform stirring, and fast heating speed.
5.2	Mixing motor	250W has overload protection function.
5.3	Work flow	8L-15L/min, adjustable flow rate.
5.4	Pumping method	Timely pumping; The spray gun switch controls the operation of the pump, and the material pump only works when the spray gun switch is pulled. Once released, the pump can immediately stop working, greatly reducing wear and extending the service life of the pump; The glue flow rate is regulated by variable frequency stepless speed regulation, ensuring safety and reliability.

6.1	Hose length	Standard configuration of 5 meters; pipe diameter Φ 16mm; AC voltage 220V, temperature 250 ° C
6.2	Material (new product)	The inner tube is made of imported Teflon, which has the advantages of being more lightweight, wear-resistant, resistant to bending, convenient for construction, and reducing the labor intensity of workers.
6.3	Heating method	Full process surround electric heating. 220V output voltage.
6.4	Temperature control form	Constant temperature control, automatic heating.
6.5	Injector	Equipped with three different sizes of spray nozzles (capable of filling cement pavement)
6.6	Voltage frequency	220V-50HZ
Control
7.1		Full process digital display, controlled by a microcomputer, can control the temperature of the hot melt kettle, heat transfer oil, and filling gun separately, achieving precise control of the heating temperature of different sealing materials.
