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. Removes oils, greases, silicones, refrigerant oils, fluxes, adhesives and other common industrial contaminants. Used for cleaning medical instruments, implants and other devices including orthopedic implants, monitoring devices, oxygen and gas lines. This solvent can be used as a carrier fluid like for silicone-based lubricant coatings. Nonflammable Much safer than most common industrial solvents — TCE, nPB, Perc & Methylene Chloride Powerful cleaner — Ideal for degreasing and contact cleaning Available in aerosol or bulk for vapor-degreasing, ultrasonic and immersion cleaning Rapid evaporation Non-ozone depleting Cleaning applications: electronics, relays, switches & breakers, transformers, and electric motors and generators NSF registered K1 and K2 Technical papers: PWR-4 performance testing Overview of health & safety impact of nPB and other toxic industrial cleaners For more information, check out our The Expert’s Guide to Degreasers & Maintenance Cleaners.
