Vacuum Vapor Degreasing is a closed-loop cleaning system that operates under vacuum conditions.

It uses vacuum technology to enhance the cleaning efficiency, performance, and drying of parts with complex geometries (blind holes, porosity, etc.) while maintaining a safe and compliant workplace.

The cleaning cycle in a vacuum vapor degreaser can include ultrasonics, immersion, vapor, spray, rotational processing, and vacuum nucleation. These systems are known to comply with all applicable EPA and OSHA regulations and are operated in countries and regions known to have the most stringent regulatory requirements.

Following the finalization of the Montreal Protocol in 1987, the EPA regulations for VOCs were monitored more stringently than before regarding the production and consumption of ozone-depleting substances (ODS). These regulations led to the development of the Freeboard zone, a secondary set of refrigeration coils, adjusted to subzero temperatures (F), in Open-Top Vapor Degreasers. This implementation reduced solvent emissions by half when compared to open-top vapor degreasers without a freeboard zone.

Inversely, a vacuum vapor degreaser uses far less solvent as compared to an open-top vapor degreaser. The vacuum vapor degreaser also offers nearly constant distillation of solvent, which provides consistent and thorough cleaning, cycle after cycle. Most modern solvents do not have a set lifespan; therefore, the vacuum vapor degreaser can reduce the costs associated with solvent consumption while still delivering the required level of cleanliness.

Baron Blakeslee vacuum vapor degreaser offers the lowest emissions technically possible. Depending on your choice of cleaning agent, a minute amount of VOC will be exhausted into the atmosphere at the end of the cleaning cycle. This VOC has the potential to be exhausted into a carbon drum, further removing or eliminating emissions. The carbon drum intends to adsorb the VOC and safely store it. Using a carbon drum mitigates the environmental risk and operator exposure levels from VOC emissions, especially in solvent-based applications. Most modern solvents have an Operator Exposure Limit of about two hundred (200) parts per million as compared to legacy solvents, such as trichloroethylene (TCE), n-propyl bromide (nPB), perchloroethylene, methylene chloride, which have Operator Exposure Limits in the range of 0.1 parts per million. Using a vacuum vapor degreaser permits the use of solvents while still complying with applicable air regulations, which is imperative for processes that require validated solvents for their cleaning process.
