BIRMINGHAM — Now available in the August issue of Water Technology, our Editorial Director Rich DiPaolo writes about the evolving UV marketplace. In the article, UV insiders such as Vikas Thusoo, B.Eng, MBA, CWS-VI, product manager and technical specialist for Envirogard Products Limited, discuss such topics as how the market has grown over the years, and has been divided into the “standard non-monitored” systems and the “NSF/ANSI 55A certified monitored” systems.

“Standard systems are widely used for residential markets and most quality units now claim the NSF 55 A UV dose at the end of lamp life. We see an increasing and wider acceptance of UV systems as primary disinfection devices for residential and commercial markets, although the light commercial markets, such as resorts, camps, motels, etc., now almost entirely [select] NSF/ANSI 55 systems.” 

Thusoo also shared six things to know about quality UV selection.

He put together a helpful checklist for dealers looking at UV systems and what to know when looking for quality UV units: 

#1 thing to know when selecting a quality UV unit: Performance

Does the UV unit maintain a consistent UV output over a wide voltage spectrum?

#2 thing to know when selecting a quality UV unit: Features

Does the UV have features such as a lamp replacement reminder, an additional solenoid output, high output lamps, etc.?

#3 thing to know when selecting a quality UV unit: Quality

Standard units should be tested at least under NSF/ANSI 61, plus additional electrical safety testing, such as CSA. NSF 55A units should also have an electrical safety testing.

#4 thing to know when selecting a quality UV unit: Dependable

The electronic ballast should be sturdy and capable of handling power fluctuations. Sensitive, cheaply constructed ballast may look nice and shiny when new, but if it cannot stand the rigors often associated with rural power, the dealer may have to keep replacing the ballast even during the warranty period.

#5 thing to know when selecting a quality UV unit: Support

Does the manufacturer have trained technical support that can help the dealer with any kind of field issues or questions?

#6 thing to know when selecting a quality UV unit: Warranty

At least seven years on the chamber and one year on the ballast.
