The Sievert hot-air family grows with ThermoPro Multi
A new handheld tool for detail welding, designed to complement our automatic ThermoWeld welding machines. Where the automatic machines handle the repetitive, high-volume joints, this tool gives the operator full control at the points that need a steady hand, such as tight corners, awkward angles, and finishing work. The result is a consistent workflow from production line to the final joint.
ThermoPro Multi
ThermoPro Multi has been developed for the jobs where an automatic welding machine cannot reach. Corners, upstands, penetrations and other detail work require a compact handheld solution, while larger continuous seams are handled by Thermoweld.
Together, the two product families give professional roofers a broader Sievert hot-air welding offer – from large membrane surfaces to the details that complete the job.
ThermoPro Multi is a professional handheld hot-air tool with stepless temperature control from 20 to 620°C. The 1,600 W tool delivers an airflow of 250 litres per minute and reaches approximately 620°C in around three minutes.
A brushless blower motor eliminates the need to replace carbon brushes, while the simple analogue temperature control keeps operation straightforward. The tool is designed around a proven platform and manufactured in Switzerland.
Built for professional detail work
Built for professional detail work
ThermoPro Multi is designed for welding and waterproofing applications involving PVC, TPO and bitumen membranes, including corners, upstands and penetrations.
Its interchangeable nozzle system allows the same tool to be adapted for different applications. Existing Sievert nozzles using the same fitting can continue to be used, giving users access to a wide range of detail-welding solutions.
Beyond roofing and waterproofing, ThermoPro Multi can also be used for applications such as PVC and TPO flooring, shrink work, drying and defrosting, and paint stripping.
The tool weighs 1.3 kg including the cable and measures 365 × 105 × 105 mm.
Simple by design
Sievert has deliberately kept ThermoPro Multi straightforward.
The analogue temperature control allows the user to set the temperature required for the material without additional displays or unnecessary electronics. The brushless motor reduces regular maintenance, while the heating element is designed to be replaceable.
A metal transport case and a range of nozzles and pressure rollers are available as accessories.
A natural addition to the Sievert range
ThermoPro Multi joins ThermoWeld as part of Sievert’s growing range of professional electric hot-air tools.
ThermoWeld handles large-area, continuous membrane welding, while ThermoPro Multi is intended for the detail work around it.
For professional roofers, this means that both automatic and handheld hot-air welding can now be covered within the Sievert range.
ThermoPro Multi will be available in a 230 V version for European markets and a 120 V version for the US market.
Sales will start after week 46, with exact availability varying by region.
