Choose the Right Arium® for Your Application
Arium® Comfort I
The Arium® Comfort I system delivers both ASTM Type 1 ultrapure water and Type 3 pure water in one system, using potable feed water as a source.
With outstanding reverse osmosis (RO) technology and unique ion-exchange cartridge, the Comfort I delivers consistently purified, high-quality water. Intelligent iJust software optimizes water usage and ensures time and labor-saving operation.
For critical applications, add the optional UV-lamp to your system (with or without a TOC monitor) or utilize our external ultrafilter to optimize water quality for your needs.
Arium® Comfort II
The Arium® Comfort II delivers ASTM Type 1 ultrapure and Type 2 pure water in one system.
Directly connected to your potable feed water source, this system uses proven reverse osmosis (RO) technology combined with the latest proprietary EDI technology and a unique ion exchange cartridge to consistently deliver high-quality water.
The innovative iJust function optimizes water usage and ensures time and labor-saving operation. Add the optional UV-lamp (with or without TOC monitor) to further reduce the TOC levels or utilize the external ultrafilter when things like endotoxins are of concern.
Arium® Bagtanks
The innovative Arium® Bagtank uses a closed system to intermediately store purified water pre-treated in the Comfort system before the polishing stage.
Dispense pure water directly from the Bagtank if needed or connect the Bagtank to another laboratory device that requires purified feed water. Choose between a 20, 50 or 100 L Bagtank.
