RO Low Pressure

TKA RO 7 DEN - An Outstanding Water purifier!


Specifically for doctors´ and dentists´ practices, university and research labs.


Reliably produces small to smallest amounts of laboratory water at a favourable cost.


Stops the need to buy "purified water" or "double-distilled quality".


Heightens the performance of autoclaves and helps preserve expensive instruments.


Economically and ecologically appr. 10 times better than distilling.


Optimally combines reverse osmosis technology with ion exchange.

TKA RO 7 DEN is a ready-to-connect reverse osmosis system, specifically developed for reliable production of demineralized water at a lower cost. The combination of a high-tech reverse osmosis membrane with two downstream mixed bed cartridges produces a pure water of quality equalling that of "purified water" or even double-distilled water.

Compact construction - fits under the table or can be hung on a wall. All components are contained in the reverse osmosis unit, with the exception of the separate pressure tank.
