Vintech Pacific introduced Ozone Sanitation to New Zealand wineries since the early 1990s as an alternative to sanitisers like chlorines and sulphur dioxide.
Ozone is a form of tri-atomic oxygen (O3), which is highly unstable and a powerful oxidant. Environmentally sound, ozonated cold water can replace traditional hot water and harsh chemical sanitation practices. Its use has been generally accepted and documented to be effective for barrel cleaning and sanitation, tank cleaning and sanitation, clean-in-place systems, and for general surface sanitation, including bottling lines.
This technology has the added benefits of reducing water, energy and chemical consumption and because ozone rapidly decays to normal diatomic oxygen (02), it leaves absolutely no toxic residue.
