 Wallace & Tiernan in Australia, New Zealand & The Pacific

Whether you’re dealing with gases, liquids, or solids, we have a solution for your process. Wallace & Tiernan® products and systems have been the leaders in gas chlorination, disinfection and chemical dosing since 1913. While it wasn't until March, 1954 that Wallace & Tiernan Pty Ltd was formed in Sydney, Australia, Wallace & Tiernan soon captured a share of the market.

 Australia imported some parts from the U.S., the UK, and Germany, and manufactured other parts locally to give their products a distinctive Australian look. Today, they offer products for water quality monitoring, treatment, analytics, chemical dosing and disinfection. The Australian operation is split between an assembly plant in South Windsor, NSW and sales offices along the East Coast, located in Melbourne - Victoria, Sydney - New South Wales and Brisbane - Queensland.

By utilising our extensive portfolio and knowledge that is designed to help the demands of engineers, industries and municipalities, we are able to provide solutions for virtually any water application. Our product range, ground-breaking technology and experience allow us to offer the right solution for all areas of water treatment and disinfection applications. We place great emphasis on quality and providing unparalleled commitment to service.
