Yes, correct. I think that after the initial investment in fluid, the VPS system is actually cheaper to run over the long term, with better results.

Agreed.  Also the secondary vapor blanket we used help prevent primary fluid loss

But the fluid lasts a long time if the oven is kept closed.

$1000 per gallon!!!  One might ask oneself why would anyone use the Condensation Soldering Process if the fluid costs that much.  Well I think the answer is simple. The condensation soldering process is a rapid, uniform heating process done in a non-oxidizing environment.



Although expensive, the fluid price hasn't increased much over the years.  Our first Condensation Soldering Facility installed in the Western Electric Manufacturing Location in Lisle, IL 39 years ago had a heated sump that required 60 gallons of FC70 fluid and at that time we paid $800 per gallon
