Why choose atg


For critical systems where dose delivery must be assured, atg UV Technology can supply 3rd party validated Ultraviolet systems for a range of applications at varying Ultraviolet transmissions (UVT%). These systems are validated to the US EPA UVDGM (Ultraviolet Disinfection Guidance Manual) Standard. This gives atg UV Technology the flexibility to offer systems for both RED dose and 1 - 5 LOG reductions.

Note: All modern systems for drinking water and make-up water applications are now expected to be validated by a 3rd party test house. atg UV have 3rd party validation using the US EPA UVDGM, a standard seen as the ‘worlds strictest performance criteria'. This ensures atg UV systems will perform and guarantees the system provided will be future proof against new specification standards and legislation.


3rd Party validation is now a major part of the UK Drinking Water Inspectorate (DWI) Guidelines on UV Disinfection February 2010. These guidelines directly reference the use of the US EPA UVDGM Standard as the preferred validation standard for drinking water companies throughout the UK. All atg UV Technology Validated systems fully conform to US EPA UVDGM standards and with the DWI Guidelines February 2010.


atg UV can offer the latest in Ultraviolet system design with a range of In-line UV systems for a vast number of applications. The In-line design offers an ultra compact, high output, low foot print UV system that requires far less installation and maintenance space than traditional ‘Axial' UV systems. Additionally, CFD modelling and 3rd party validation has proven that the In-line design offers superior performance when compared to standard systems offered by other manufacturers.

Unlike many other UV manufacturers, atg UV's wiper system does not use limit switches as they have proven to be unreliable. Rather, atg UV systems use embedded pulse technology and a robust mechanical wiper to provide a durable and effective quartz cleaning system.


atg UV's attitude to design and manufacture is driven by a ‘quality first' approach. As an ISO 9001 company and Queens Award Winner with Achelies UVBD and NSF accreditation, you can be assured that all atg UV products are consistently engineered to the highest standards.
