When it comes to safety barriers there is a big difference between a traditional light curtain and the Frommelt Guardian Defender.
Machine protection you can see, feel and depend on.
Trusted to contain application hazards including weld flash, sparks, mist, flying debris and other exposure. Guardian Defender replaces inefficient electronic systems with a dependable physical automated barrier that can help you comply with the latest safety standards.
Light curtains requiring extra buffer of floor space to create a safety cell. Guardian Defender can eliminate that required buffer zone. Staging areas can be placed closer to the process, conserving motion, improving ergonomics and increasing productivity.
There isn't a light curtain in the world that can stop sparks from flying, chips and fluid from spraying or fluid from spreading, but Guardian Defender can.
