UniVario System DN625 – Odour and Inflow Water Protection System

With the UNITECHNICS UniVario System DN625 you reliably prevent odour nuisance from sewer shafts while at the same time providing secure protection against inflowing extraneous water.
The complete system combines a powerful inflow water seal with a highly effective odour control module – for maximum operational safety, optimal shaft ventilation and significantly improved air quality in the surrounding area.

Innovative, low-maintenance 2-in-1 design

The UniVario System DN625 combines the proven functions of the predecessor models Uni-FreWa (extraneous water protection) and Uni-AdSorber (odour control) in one modular complete system.
The integrated extraneous water seal closes automatically when surface water flows in and reopens on its own once the water has drained, ensuring full ventilation in accordance with DIN EN 124.
The enlarged adsorber filter volume provides effective, long-lasting neutralisation of sewer odours without any need to replace the filter.

Simple installation and maximum workplace safety

Installation is tool-free and requires no entry into the shaft.
The adsorber and extraneous water protection unit remains easily accessible from the surface, eliminating the need to open the manhole cover unnecessarily and avoiding hazardous shaft entries.
This increases workplace safety while reducing the effort required for inspection and maintenance.

High-quality materials for durability

The UniVario System was designed for permanent use in the sewer.
The robust, corrosion-resistant construction ensures a long service life, low operating costs and reliable functionality even under demanding conditions.
The integrated sediment chamber also allows for quick and easy cleaning when maintenance is required.

Tailor-made solutions for special requirements

For special applications – e.g. industrial shafts or aggressive media – special sizes and custom versions are available.
We are happy to advise you on individual requirements or non-standard installation situations.
