Soft-Touch Pinch Point Safety Systems
Protect your most valuable assets—your operators. Unitrol’s
Soft-Touch Safety Systems are the industry standard for pinch point protection. Unlike light curtains or guards that can be bypassed, Soft-Touch is integrated directly into the machine control. It prevents the welder from applying high force if an obstruction is detected, significantly reducing the risk of injury without slowing down production.
Automotive-Grade Water Chillers
Consistent temperature control is vital for weld repeatability and transformer health. We provide Unitrol
closed-loop water chillers, ranging from compact
1/3-ton units to heavy-duty 50-ton systems. These automotive-grade chillers are built for 24/7 industrial use, ensuring your electrodes and transformers stay cool even under the most demanding duty cycles.
