versatile, easy to maintain, efficient
The UNIROOF AT/ST homogeneously welds single-ply thermoplastic liner, as well as bituminous materials, such as EPDM. But its ultra-thin housing design and movable transport axle are what really makes the machine stand out. It can fit into tight spaces just as easily as on top of a roof parapet. And with its integrated direct-driven, maintenance-free pressure wheel, it rises above competitive products with its higher pressure and noticeably greater welding speed. It is lightweight among other automatic roof welders; at 17.5 kg (39 lbs.), the UNIROOF AT/ST is surprisingly easily portable. Available as a fully-regulated AT version with digital display or as a controlled ST version with potentiometer.
MINIFLOOR Drive Unit
handy, economical, versatile
The MINIFLOOR Drive Unit turns the TRIAC hot air hand tool into a hot air welder in just a few seconds with undeniable flexibility. That significantly increases welding quality as well as reliability and makes work easier. Among MINIFLOOR’s special features: it can weld wall to wall so that welding the ends afterwards is not necessary. Seamlessly welds short joints and small surfaces almost twice as fast as by hand. Its dual axis drive ensures that it stays perfectly true to the groove. At just 5.3 kg it can be easily transported.
