nPB Solvents

EnSolv®: n-Propyl Bromide (nPB) Solvents

Since creating the nPB solvent market in 1994, Enviro Tech has made it our mission to be the best and most knowledgeable supplier of high-quality, stabilized n-propyl bromide industrial cleaners. Our commitment has led to a superior cleaning solution for metal degreasing and precision cleaning.

Ensolv® Brand n-Propyl Bromide (nPB)

For more than two decades, Enviro Tech International, Inc. has been manufacturing EnSolv, a revolutionary n-propyl bromide-based vapor degreasing and industrial cleaning solvent used around the world. EnSolv is specifically formulated to address the difficult cleaning problems experienced in high-tech industries that require exceptional levels of cleanliness. Some of our EnSolv products Include:

All variations of EnSolv Solvents leave virtually no residue and conform to SAE ARP 1176. Furthermore, EnSolv is the most stable nPB solvent available; its original patented stabilizer formula provides for consistent performance and rust inhibition, in addition to superior soil penetration and lifting properties.

Enviro Tech promotes strict quality-control procedures, ensuring that each individual raw ingredient that goes into EnSolv is optimally prepared. Our rigid standards and overall commitment to excellence even led Boeing to approve EnSolv 5408 as the first ever nPB solvent alternative to trichloroethylene (TCE) and perchloroethylene (PCE or PERC) under the BAC5408 vapor degreasing specification.

EnSolv offers a better degree of environmentally friendly cleaning due to low global warming and ozone depletion potential. Other unique benefits of EnSolv include:

  • Stability — even with titanium, light metals and alloys
  • Simple drop-in replacement for trichloroethylene and other chlorinated solvents
  • Very high solvency power for exceptionally fast cleaning
  • Mid-range temperature operation, which reduces energy use, promotes a faster cleaning cycle and makes it easier to handle
  • Versatility — use EnSolv in any vapor degreasing equipment for improved productivity and lower maintenance
  • U.S. SNAP approval


Tech Kleen® Brand n-Propyl Bromide (nPB)

Tech Kleen, another powerful nPB-based vapor degreaser, is used across multiple industries throughout the country to clean everything from grease and oil to flux and mold. Its advanced formulation tackles the frustrating cleaning problems experienced by manufacturers every day.

Enviro Tech is proud to offer Tech Kleen to industrial professionals who are seeking a direct replacement for the more harmful chlorinated solvents. Similar to EnSolv, multinational corporations, including Boeing, have approved Tech Kleen as a replacement for trichloroethylene.

Tech Kleen products include:

  • Tech Kleen® STNPB AG
    This is the version of Tech Kleen that was approved by Boeing (Boeing Vapor Degreasing Specification BAC5408, PSD 6-65). Manufacturing professionals in the aerospace industry use it to clean a variety of metallic parts, including engine blades and landing gear.
  • Tech Kleen® RECLAIM
    When precision cleaning isn’t a #1 priority but the job still has to get finished, industrial professionals choose RECLAIM, the cost-effective alternative to STNPB. By recycling n-propyl bromide, Enviro Tech is able to deliver the same high-quality results at a discounted price.
  • Tech Kleen® BOOSTER
    Each variation of Tech Kleen contains stabilizers that prevent the solvent from turning acidic and ultimately becoming unusable. Tech Kleen BOOSTER is a proprietary blend that can be mixed into any Tech Kleen formula to replenish stabilizers and prolong use.
  • Tech Kleen® AER
    AER is a bulk variation of the nPB chemistry available in drums or in bulk, designed for packaging into aerosol cans for various uses, as carriers for other products like silicones or lubricants, or as a degreaser or electrical contact cleaner/defluxer.
