The new TX Online UV transmittance analyser from Hanovia has been specifically designed to provide accurate monitoring of UV water disinfection systems in the food and beverage, brewing, pharmaceutical, electronics, aquaculture and marine (ballast water treatment) industries. The TX Online’s one-piece design allows simple mounting and uses minimal space. Its new optics provide increased accuracy and more consistent readings with online and laboratory analysers.

A unique feature of the TX Online is an ultrasonic automatic cleaning system that keeps the optical chamber clean at all times. This ensures accurate, consistent reading of percentage UV transmittance at all times and reduces the need for manual cleaning. In addition, a bubble rejection system which eliminates air from a sample while simultaneously creating a vortex cleaning action throughout the optical chamber.

The unit has a 0 - 100% transmittance range and response time can be adjusted to allow the user to program readings between 4 - 60 seconds. Calibration is inexpensive due to the small sample volume requited (only 30ml) and removable sample cuvettes allow for easy cleaning and calibrating. An adjustable backlight display allows viewing in low light conditions. A 4-20 mA output is provided as standard and an RS-485 output with Modbus protocol is available as an optional extra.

The TX Online is certified to CE, UL and CSA (ETL, ETLc). The calibration standard is prepared as outlines in ‘Standard Methods for the Examination of Water and Wastewater, 20th Edition, Method 1080 A-C, Methods for Preparation of Reagent Water’.

UV disinfection specialist Hanovia has won the contract to supply UV disinfection systems for the indoor pools at the new Hillcrest Aquatic Centre, currently under construction in Vancouver, Canada.

The Aquatic Centre is being build in conjunction with the adjacent Hillcrest Curling Venue for the 2010 Vancouver Winter Games. After the Games the Curling Venue will convert to the Riley Park Community Centre, which will be fully integrated with the new Aquatic Centre, which will include the 50 metre pool, a leisure tank and an outdoor aquatic element.

Hanovia UV disinfection systems are compact and can usually be installed within existing pipework with minimal disruption. The UV lamps can be fitted with an automatic wiper that keep the sleeve housing the UV lamp clean, so the only regular maintenance required is changing the lamp every nine to twelve months – a simple operation that is carried out by on-site staff.
