Safe, Effective Vapor Degreaser Solvents

Techspray has an array of vapor degreasing cleaners that are engineered to be less toxic than many other solvents, yet powerful enough for the most difficult soils.

Vapor degreasing is a cleaning process that involves rinsing and cleaning parts in ultra-pure vapor. The process doesn’t require any water or scrubbing and is used to safely clean various materials like plastic, glass, metal, gold, and ceramic.

Vapor degreasing can be found in any industry where precision cleaning is critical. It is common in the automotive, aviation and aerospace fields, and in medical device, jewelry, and electronic assembly manufacturing.

Precision-V vapor degreasing solvents are ideal replacements for cleaners containing Freon, HFC-141b, and AK225. Exposure to Precision-V solvents is less hazardous than many other solvents:  TCE (trichloroethylene, CAS #79-01-6), nPB (n-propyl bromide, CAS #106-94-5), and perc (perchloroethylene, CAS #127-18-4).

For the closest (and safest) cost and performance match to n-propyl bromide, nothing beats PWR-4 Maintenance Cleaner and PWR-4 Flux Remover.

FAQ's

What is vapor degreasing?
Vapor degreasing is a highly efficient and widely used industrial cleaning process designed to remove grease, oils, waxes, fluxes, and other contaminants from various metal, plastic, and electronic components. Vapor degreasing is a valuable cleaning method for industries that require precise and thorough cleaning of parts, such as aerospace, automotive, electronics, and medical device manufacturing.

The vapor degreasing process typically takes place in a closed chamber or tank with two distinct sections. The lower section contains the solvent, while the upper section holds the parts to be cleaned. The solvent is heated to its boiling point, creating vapor that rises and comes into contact with the soiled parts. As the vapor condenses on the colder surfaces of the components, it liquefies and effectively dissolves the contaminants. Gravity then causes the dissolved contaminants to drain off the parts and settle in the bottom of the tank.

The key advantages of vapor degreasing are its ability to remove stubborn contaminants thoroughly and quickly, its compatibility with various materials, and its relatively low energy consumption compared to other cleaning methods. It is also a closed-loop process, so solvent is reclaims and used over-and-over. Additionally, the process can be automated for large-scale industrial applications, leading to increased productivity and consistency in the cleaning results.

Is vapor degreasing safe?
Vapor degreasing can be safe when appropriate solvents are used, and safety guidelines are strictly followed. However, to ensure safety, it is essential to assess the specific process, equipment, and materials involved and take necessary precautions accordingly.

Here are some safety considerations for vapor degreasing:
  • Solvent Choice: The safety of vapor degreasing largely depends on the solvent used. Some solvents, such as chlorinated solvents like trichloroethylene (TCE) and perchloroethylene (perc), and bromiated solvent like n-propyl bromide (nPB) have been associated with health and environmental hazards. These solvents can pose serious risks if not handled properly, and their use is being phased out or regulated in many regions. We offer many alternatives with much lower toxicity, and we do not offer TCE, perc, and nPB because of the health concerns.
  • Ventilation: Adequate ventilation is crucial to prevent the buildup of potentially harmful solvent vapors in the workspace. Proper ventilation helps maintain air quality and reduces the risk of exposure for workers.
  • Personal Protective Equipment (PPE): Employees working with vapor degreasing equipment should wear appropriate personal protective equipment, such as gloves, goggles, and respirators, to protect against potential contact with solvents or vapor inhalation.
  • Environmental Impact: Adequate disposal methods and compliance with environmental regulations are necessary to minimize the impact on the environment.
  • Training and Safety Measures: Workers involved in vapor degreasing should receive proper training on handling solvents, operating equipment, and understanding safety protocols to minimize risks.

How can you reduce chemical exposure?

Every organization using hazardous chemicals within their facility has the responsibility to equip their facility and personnel to maintain exposure levels below the TLV. Personal monitoring badges can be used to measure exposure of a specific material. Then, depending on the threshold limit and the application, exposure can be controlled with PPE like masks, face shields, respirators, and even coveralls. If they don’t reduce exposure below the recommended limit, you will need to consider a special ventilation hood or even containment booth. As you can see, as the exposure limit gets down to a certain level, the equipment required to safely use the solvent can get impractical. At that point, your best option is to consider a safer alternative.
