PWR-4 Industrial Maintenance Cleaner
PWR-4 Maint Cleaner – 54 gal
Powerful, nonflammable & cost effective cleaner that is a safer nPB replacement

PWR-4… The Safer, Powerful n-Propyl Bromide (nPB) Replacement

PWR-4™ Industrial Maintenance Cleaner Blasts away oil and contaminants off of contacts, printed circuit boards, barcode instruments, switch boxes, gear boxes, and electronic motor controllers. Grease and oil flow right off, reducing the time and materials needed to scrub off stubborn soils.

Ideal where a safer, nonflammable, and cost effective cleaner is required. This innovative solvent is much safer than the four most common industrial solvents: TCE, nPB, Perc and Methylene Chloride and quickly cleans the most difficult greases and oils from electronics, relays, and motors. It is engineered to remain stable and effective over thousands of cycles in vapor degreasing equipment.

Vapor Degreaser Setting Guidelines

• Boiling point – 118°F / 48°C
• Boil sump temp set – 127°F / 53°C  
• High solvent temp set – 136°F / 58°C
• Refrigerant high temp set – 109°F / 43°C

Note: As with all vapor degreaser equipment and processes, observe all safety precautions, guidelines and operating rules associated with these units. Failure to do so may put operations personnel at risk. Avoid excessive vapor losses, loss of refrigeration, excessive boil sump heat, etc. Make sure all equipment is operated in accordance with the manufacturer’s guidelines and instructions. If in doubt, contact your manufacturer immediately.
