1. Security and humanized design

With a spring shock absorber and gas spring shock absorber dual shock absorption system, greatly improving the safety performance of walking, hot melt kettle has two front and rear feed port, feed pump switch located in the operating handle, easy to operate construction.

2. Temperature control box

Japan Omron brand dual digital LCD thermostat timely display and adjust the heat transfer oil temperature, sealant temperature and irrigation hose temperature, temperature display intuitive and accurate, through three centralized temperature distribution switch can be controlled independently, easy to be operated.

3. Irrigation gun

The unique electric control switch on the handle of the gun can remotely control the pump and reduce the waste of sealant.

4. Heat conduction oil system

Melt with a heat transfer oil hot melt kettle, indirect heating, the temperature can be adjusted on demand, automatic temperature control system, will never burn the filling material. The hot melt kettle thermal transfer oil sandwich design than similar products using less heat transfer oil, to further improve the heating rate, reduce the replacement cost.

5. Special geometry structure of the combustion chamber

Flame to 45°oblique angle to the combustion chamber wall, not with the hot-melt kettle in direct contact with the hot room air, combustion, high heat utilization.

6. Discharge hose

270° on demand free rotation, longer life, high resistance hose fold fully meet the road maintenance in the construction of horizontal and vertical cracks in the actual work needs to ensure that the largest construction area.

7. The lowest charge height

Low operating position and filler port, the filler port is equipped with a splash plate, improve the safety of the feeding operation. Both the material box and the hose have heat insulation materials to avoid scalding the operator.

8. Electric agitator

Mixer motor imported brand variable speed motor motor, simple structure, easy to use, easy to maintenance.

9. Moving Way—Trailer type and Hand-push walking

Small size, light weight, both trailer/hand-push walking are ok, just two people can carry out construction.
