Dip Spin information needed

We are an Aerospace fastener manufacturer. We have requirements to lubricate many of our products using a cetyl alcohol solution. The cetyl alcohol flakes are dissolved in a naphtha type solvent. The work is dipped in the solution maintained at a temperature of 125 degrees F, and the excess spun off and dried in a spin dryer. We have been using a specially built unit that encloses both the solution tank and the spin dryer. This piece of equipment is worn out and must be replaced soon. It was built for the purpose of minimizing the solvent emissions by containing them. I am interested in the Dip Spin method of application, but question the practicality to maintain the solution at the required 125 degree point, and the control of solvent fume emissions. I would like to hear comments from anyone who is familiar with using Dip spin equipment for a similar purpose..

This is in addition to your question...I have looked into this process and found a Cal/OSHA regulation (5430) that states that when dip tank liquids are heated, provision shall be made to prevent a temperature rise greater than 50 degrees F. below the flash point of the liquid. I believe the flash point of this solution is about 50 F.
