Hot air technology is the way in which we can join or seal premade membranes of PVC and TPO. Hot air equipment can be manual or semi-automatic. It can be used in workshops or roofs. Hot air equipment has an air heat blower that sucks in and expels air through a nozzle, which has a ceramic resistor that heats the air flow up to approximately 650 degrees. One of the greatest advantages of this sort of sealing is that no duct tape or glue is required, because the sealing is performed by overlapping the same material of tarps and membranes by means of heat.

The use of this hot air technology is very handy when installing pre-made PVC and TPO membranes to coat or waterproof commercial, industrial or residential roofs. The advantages of this waterproofing system are the durability and resistance against water and solar rays, and the heating benefits it provides. The floor semi-automatic equipment has the advantage that the sealing process is faster and depends less on the operator’s ability to achieve a tight installation.

Heat guns are ideal equipment for welding any sort of thermoplastics, such as polyethylene, polypropylene, PVC, CPVC, PVDF, etc. Plastic welding is mainly used in construction of tubs, tanks, water and chemical containers, and as part of an industrial process.
Heat guns are air heat blowers that suck in and expel air through a nozzle, which has a ceramic resistor that heats the air flow up to approximately 650 degrees. This allows to heat the filler material (weld) and bring it to a thermoplastic state, which varies according to the material.
Digital heat guns are recommended when welding high-thickness plastics is required and when welding plastics in extreme weather conditions. In plastic welding it's important to choose the right equipment according to the application. This is determined based on the type of material, thickness, surface and other variables to be taken into consideration. The speed to weld with a heat gun depends on the regulation of the temperature and the pressure exerted by the cord on the base material. The determinant feature for a well-done weld with a heat gun is the stability of the temperature during the preheating stage and that of the mass or filler material. Furthermore one must bear in mind that to achieve good results, plastic welding must be carried out by trained personnel with the adequate material, equipment and tools.
