SOG® Systeme - Innovations Made in Germany   

Experiencing unpleasant odours in the limited space available in a motorhome or caravan is a taboo topic for many users, despite the fact that such stenches have significantly dampened the holiday mood of virtually every camper at least once.

The company SOG®Systeme OHG, which was founded in 1994, uses its many years of development experience to offer a variety of different ventilation systems for the optimisation of toilets. The main objective of the company's patented systems is to enable caravan and motorhome toilets to be used without chemicals while also increasing the comfort of using such toilets by eliminating odours.

Environmentally friendly solutions made in Germany
SOG®Systeme OHG produces all of its environmentally friendly systems at its own manufacturing facilities in Germany and on the basis of high quality standards. The systems are mainly offered as original equipment but are also provided as retrofit solutions. The company primarily uses marketing activities in Europe to sell its products, but exports to Australia, the US, New Zealand and Japan are also constantly increasing.  
Individual solutions
As an OEM supplier, the company offers individually and technically adapted solutions for the wide variety of installation options available in different recreation vehicle models in order to guarantee smooth production processes.

Award-winning engineering performance
Our SOG® systems have been presented with a number of awards, for example recently receiving the Lupo Award (the "Oscar" of the caravanning industry), winning the Inventor Award in 2006 and being voted into first place in the "Accessory of the Year" competition by readers of the specialist magazine "promobil". On top of this, the German consumer organisation "Stiftung Warentest" approved the excellent effects of our SOG® systems in enabling the use of toilets without chemicals in as early as June 1997.
