What Customers Are Saying
“It was a pleasure working with Philadelphia Safety Devices. All six explosion doors were installed within our shutdown timeframe. The crew was professional, and the whole job couldn’t have gone more smoothly.”
“We had a two-day window to replace the relief doors on our dust collector. PSD confirmed the dimensions before the outage, and the new doors fit the existing openings without field modifications. We handed the collector back to operations on schedule.”
“Our drawings for the existing collector were incomplete. PSD walked us through what to measure and answered our installer’s questions before the equipment arrived. That made the installation straightforward for our crew.”
