The vessels were installed at the site near Windygates last weekend as part of a £40 million project to increase the efficiency and environmental performance of the distillery.
Diageo is investing £100 million in all to expand its Scotch Whisky operations and capitalise on growing interest in the spirit. Export sales topped £2.8 billion last year, a rise of 14% on the previous year, according to figures from the Scotch Whisky Association.
As well as expanding Cameronbridge, the drinks giant plans to build a new malt distillery on Speyside.
The new vessels, also known as fermenters, are phase two of a four-phase project and will play a key role in producing Diageo's whisky brands such as Bell's and Johnnie Walker.
