For use with "Drain-Zyme" kitchen enzyme grease trap and drain degreaser.




It is no longer acceptable to pour harsh caustic chemicals or acids down the drain to clear fat build up or blockages. The DN3 provides accurate automatic dosing of environmentally friendly enzyme based chemicals (Drain-Zyme) that will naturally prevent the build up of fat, providing they are applied regularly at the appropriate time of day.




Drainage outlets in areas where food preparation is taking place should have a means of preventing fat build up which can lead to blockages and odour problems. The DN3 biological drain dosing system can be installed directly into the drain outlet, grease traps, pumping stations or urinals.




How does it work:

The DN3 will dispense a pre-determined volume of enzyme chemical (Drain-Zyme) into the drainage system at pre set times. The timing is critical as detergents and bleaches can destroy the enzymes if they are flowing through the drainage system at the same time. The enzyme product (Drain-Zyme) is able to remove fat and grease deposits because it contains millions of naturally occurring micro-organisms, which degrade fats and grease leaving the drainage system flowing and odour free.




Flexible: It is recommended that the enzyme (Drain-Zyme) is dispensed at a time when the drainage system is not being used. To accommodate this requirement the DN3 provides 9 programmes allowing you to set individual times per day, the same set times Monday to Friday, the same set times Monday to Sunday, or different times for week days and week ends.

Easy to install:

The DN3 can be supplied mains or battery operated. The mains version will require a 3 amp electrical supply. To ensure maximum results it is recommended that the DN3 outlet is connected to the waste pipe after the last discharge point (usually a sink) just ahead of any grease trap. If there is no grease trap the unit should be connected to the waste pipe after the P trap. Adjustable pipe fittings for use with the DN3 are available.

The DN3 is supplied with 1 x 2m clear PVC tubing 1x base connector


The IP66 Polycarbonate enclosure provides protection against water ingress and high temperature environments

*Please state whether you want the mains or battery operated*
