ATG WF Range

The Worlds’ Most Compact UV System

Launched at the Piscina & Wellness exhibition October 2015, the WF range is the next generation of aquatic medium pressure UV systems designed specifically for the swimming pool industry.

The WF design, also known as the Wafer due to its unique UV chamber design, will offer the most compact UV system available in the aquatics market today.  At around a third of the size of comparative UV systems, and with significantly reduced maintenance space, the WF series promises to offer easy to install and retrofit solutions, that will fit the tightest of plant rooms.

Whist the WF range is designed to be the most compact UV system on the market, its hydraulically optimised reactor design and leading polychromatic lamp technology will also make it one of the most efficient and best performing.  As a minimum, the WF range will provide a 99.9% reduction of chlorine resistant microorganisms such as Cryptosporidium and Giardia.


Featuring 4 models in the range, in single lamp and twin lamp configurations, the WF series is suitable for swimming pool flow rates of 5 m3/hr up to 400 m3/hr.  As with atg UV’s market leading ECL and SX ranges, the WF range will include UV Intensity Monitoring, over temperature control, automatic cleaning systems and enhanced safety quick release TwistlokTM UV Lamps.

Operators will also benefit from the inclusion of atg UV’s premium SPECTRA II control system as standard, which includes a wide range of features such as data stream monitoring, process interlocks and programmable set points.  A key feature includes variable power stepping from 100% to 50% power at no extra cost, allowing operators to optimise the operational power of their system to match bather loads and pool opening times.

In addition, SPECTRA II features a reactive boost function that will automatically operate the lamps at maximum power from a combined chlorine alarm signal when teamed with a suitable chlorine controller.  This is a feature specifically designed for swimming pool applications to break down problem chloramines as soon as they are detected, significantly improving water quality and eliminating the cause of strong chemical smells, red burning eyes, itchy skin and building corrosion.
