AquaRO² & EDI²

The series of AquaRO², AquaRO²DI, and EDI² is based on reverse osmosis (RO) units to produce deionized water. The EDI² series further processes the osmosis water by using an EDI cell to get Type II water. All systems provide you with reliable and compact systems at low operating costs. The advantage of both series is the flexibility in terms of configuration.

A production rate of 8 to 40 L/h in three different degrees of pure water (10 µS/cm to 0.2 µS/cm) is available. Optionally the systems can be equipped with a dispenser. The customer can select a 35 L,70 L, or individual tank size.

-TOTAL ORGANIC CARBON (TOC)

Options

BENCH INTEGRATED CONFIGURATION (BI VERSION)

To save valuable benchtop space the system can be ordered as BI configuration. The system will be installed underneath the workbench and only the display and dispenser are mounted on the wall

WALL MOUNTED CONFIGURATION

To save valuable benchtop space the system can be ordered as a wall-mounted configuration. the whole system can be mounted on the wall with an inclined display

External pump

Compact pump is required when feeding laboratory equipment such as autoclaves or laboratory dish washers.

TOC- Monitoring (TI Version)

The TOC monitoring during production and intermittent measurements during non-use periods allows to check the organic content in water continuously. The TOC value is measured between 1 and 999 ppb and can be shown in the display to monitor organic impurities.

VOLUMETRIC DISPENSING

Upgrade of system with fixed and flexible dispenser for the series of AquaRO² 10 + 20 and EDI² 10 + 20.

ADDITIONAL TANK

The series of AquaRO² and EDI² can be equipped with a tank of 35 L or 70 L or individual size and if requested also with an integrated UV lamp. An exception is the AquaoRO² 8 P10 with an integrated tank of 10 liters.
