The UNIROOF AT/ST homogeneously welds thermoplastic plastic sealing sheets as well as bituminous materials, such as EPDM. But its ultra-thin housing design and movable transport axes is what really makes it stand out. It can fit in tight spaces just as easily as about or on top of a roof parapet. And with its integrated direct-driven, maintenance-free pressure wheel, it rises above the competitor products for its higher pressure and noticeably greater welding speed. It is a light-weight among roof machines with 17.5 kg and easily portable. Available as a fully regulated AT version with digital display or as a controlled ST version with potentiometer.
