PWR-4 Flux Remover
PWR-4 Flux Remover – 5 gal
Powerful, non-flammable, cost effective flux removal — safer nPB replacement

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

PWR-4™ Flux Remover is 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 baked-on R, RMA & no-clean fluxes from electronic assemblies. It is engineered to remain stable and effective over thousands of cycles in vapor degreasing equipment.

• Nonflammable
• Much safer than most common industrial solvents — TCE, nPB, Perc & Methylene Chloride
• Powerful cleaner – Effective on R, RMA & no-clean fluxes
• Available in bulk for vapor-degreasing, ultra-sonic and immersion cleaning
• Rapid evaporation
• Non-ozone depleting

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.
