Atlas L79 UV Unit

The Atlas L79 UV unit is great for domestic UV water treatment of small homes and cottages, or slightly larger homes where there is less demand on water use. With ultimate quality in mind, an Atlas L79 UV has everything you need to get started safe, UV disinfection.

As the table below shows, this package is suited for 5 bedroom + properties where the peak water demand is unlikely to exceed 79l/min or 4.7m3/hr throughout the property. The Atlas 79 UV unit provides a dosage of 30 mJ/cm² (at end of its 1 year lamp life). This UV unit is manufactured with domestic drinking water treatment in mind and though you can use it for an aquarium, the UV dose will be higher than you would normally need. Please see the technical details for further information. Additional UV unit options are available on request.

The highly efficient ballast provides a visual display for information including remaining UV lamp life and total days of operation using the full colour LCD display. Its output is multi-voltage (100-240V. 50-60 Hz.) so it can be used on a mains supply or with any true sine wave generator.

The complete CE certified UV system is fully manufactured in Canada by one of the biggest companies in the UV market. UV lamp changes are easily accomplished without interrupting the water flow and without needing any additional tools. Atlas L79 UV unit Instructions are included in the box and available as a PDF.
