When evaluating duplex strainers, the consideration should be focused on both performance and the total cost of owning and operating (life cycle costs) the strainer. The designs of Tate Andale's duplex strainers are uncompromised by an accountant's pencil. The thick, heavy bodied walls provide unparalleled corrosion allowance. The straining ratios are some of the highest available. The moving parts are designed to minimize wear. Available wedgewire baskets are the most durable straining elements on the market. All of this adds up to produce the longest living, most cost efficient, high performance strainers available. In some cases, Tate Andale strainers may cost slightly more than our competitors, however spreading this cost over a life expectancy measured in decades, not years, demonstrates that the competing products cost more over the long-term.
The high straining ratios, aside from the performance benefits, contribute to lower operating costs because the baskets do not need to be cleaned as often. In analyzing the life cycle costs of Tate Andale strainers versus the competition, our designs provide the lowest life cycle costs in the industry.

Duplex units are recommended for continuous operations, and where heavy duty straining is required. A diverter valve switches the flow from one basket to the other, permitting removal of the out-of-service basket for cleaning.
