High-precision cleaning is required across many sectors, including aerospace, defense, medical device manufacturing, pharmaceutical processing, semiconductor/electronics, and more. In this comprehensive reference work, solvent cleaning equipment is thoroughly covered with a focus on the engineering details of its operation and selection. Key data is provided alongside practical guidance, giving scientists and engineers in multiple sectors the information they need not only to choose the correct machine in the first place, but also how to operate it effectively and efficiently.

Low emission open-top vapor degreasers, enclosed machines of the vacuum and pressurized type, cosolvent machines, and adsorption of "tailpipe emissions" are covered in detail and fully illustrated in color. This unique book covers material known by designers and manufacturers of solvent cleaning machines, but not collected and organized for the benefit of users.

The comprehensive coverage provided by John Durkee makes this book relevant and timely not only for readers who wish to know more about how solvent cleaning equipment works but also those who are under pressure from environmental regulators or corporate management to find effective alternatives and those engaged in non-solvent cleaning operations who are unsatisfied with their cleaning results.

Key Features

  • Clear, straightforward explanations of how various types of cleaning solvents should be managed to clean parts
  • Full-color, hand-drawn illustrations and photographs of the important internal sections of solvent cleaning machines
  • Design calculations of operating parameters in solvent cleaning machines


Engineers and scientists involved in precison cleaning across sectors including aerospace, defense, medical device manufacturing, pharmaceutical processing, semiconductor / electronics, etc.
