Burkert chosen for innovative water
deioniser
When Adept Pure Water began the design and development of its latest Di-on-x automatic deionisers, its engineers looked for a supplier of fluid control equipment that could provide a complete package
Adept Pure Water Techniques, based in Desborough near Kettering, Northamptonshire manufactures a range of water purification equipment The equipment is used for industrial applications such as electro plating and paint shop rinses, chemical manufacturing, boiler feeds, pharmaceutical manufacture and electronic component manufacture, where there is a requirement for low conductivity high quality water

When the company began the design and development of its latest Di-on-x automatic deionisers, its engineers looked for a supplier of fluid control equipment that could provide a complete package.
As a spokesman explains: "Conventional pure water deioniser installations need a large floor area to accommodate equipment such as water tanks, pumps, valves, flowmeters and pipework.
However, the Di-on-x is a new range of automatic, twin-bed, regenerating water deionisers that accommodates all the components and pipework in a very compact and space-saving, skid-mounted package".

He adds that the emphasis on packaging and ease of maintenance also focused the company on the decision to specify the complete package from Burkert.
Like other water deionisers, the Di-on-x takes in towns water and passes it through beds of cation and anion resin to remove impurities via ion exchange.
Unlike most, it uses Burkert components to monitor and control key operations.
One of the more innovative applications is the use of four set points in a Burkert conductivity meter to accurately and continuously monitor water to ensure that it is to the required standard (0.055 microS/cm to 50 microS/cm) This also contributes to savings by allowing water to be re-passed through the system, that would normally be rejected and rinsed to drain by other deionisers.
Using this approach to polish the resin beds has increased the production capacity of the Di-on-x deioniser, making the system more cost efficient to operate.
A new Burkert multifunctional 24 VDC solenoid valve island was specified to allow air to be used to control all the valves on the deioniser.
The Adept spokesman says the solenoid system helps to reduce stock and gives engineers the flexibility to build banks of solenoid valves "on-demand" to suit their needs.
An in-line flow meter measures and indicates the flow rate via a display unit that is programmed with diagnostic alarms to warn if there is "no flow".
It also provides totals of the last three production capacity runs, and the total amount of water produced in cubic metres.
Three different sizes of Burkert spring closed valves are being used, ranging from 0.5" to 2".
One valve size is fitted with a PTFE diaphragm to give chemical resistance and reduce maintenance, and all others with EPDM diaphragms for mechanical reliability.
Summing up, Adept Pure Water Techniques wanted to source everything as a package from a single proven supplier and fortunately, Burkert was able to provide the components, engineering and systems expertise to support them. Request a free brochure from Burkert Fluid Control Systems ...
