Web-Guided Tour

In addition, choosing among pneumatic, hydraulic or electronic web guide controls may not be as clearcut as prevailing wisdom suggests. "There's a common belief that you can't use electronic web guides in explosive or hazardous environments, but many of them feature explosion-proof motors and intrinsically safe barriers, or limited energy circuits, that prevent sparks," says Joe Klimczak, project engineer at AccuWeb, Madison, WI. He adds there is a misconception that hydraulic or pneumatic guides are the least expensive control options, when they may harbor high installation costs.
