Refineries, rigs, and processing plants clean under constraints no other industry has: classified hazardous locations, plant voltages, crude and paraffin that cold water won't move, and pressure-test requirements written into code. This collection is built for those constraints: explosion proof hot water pressure washers, 480V all-electric units for indoor plant use, oil-fired steam cleaners for degreasing, 7,000 to 12,000 PSI water blasters for exchanger bundles and surface prep, hydrostatic test pumps, and the rated hose, guns, reels, rupture disks, and waterblast PPE that high-pressure work demands.
