The SERVOTOUGH OxyExact 2200

The OxyExact 2200 provides hazardous area oxygen analysis

The high-specification OxyExact 2200 O2 analyzer offers an unrivaled combination of precision, flexibility and performance for optimum process and safety control. The OxyExact 2200 can be configured with a hazardous area control unit with up to six transmitters.

A process oxygen analyzer for ultimate monitoring performance

The OxyExact 2200 combines high precision Paramagnetic O2 sensing technology into a flexible and robust safety-enhanced design, optimized to meet the needs of demanding process monitoring applications like feedstock purity testing and clean up, hydrogen and chlorine production, solvent recovery and oxidation control processes, ethylene oxide (EO) and ethylene dichloride (EDC) production.

It uses an innovative three-enclosure system that facilitates simplified and versatile sampling of any flammable gas up to 100% O2 (oxygen enriched) – with no need for pre-sample drying – dramatically reducing ongoing costs.

Up to six analyzers can be linked to a single control unit, ensuring the high performance and adaptability required by the most dangerous process control environments.

Unrivalled performance for the most demanding oxygen process monitoring

When you work in hazardous area process monitoring applications, a highly accurate, safe O2 analytical solution that samples any flammable gas mixture up to 100% O2 is crucial. No matter what your monitoring requirement, you need an analytical solution that offers operational flexibility, exceptional safety and the opportunity to reduce costs. We don’t believe you should have to compromise.

A no-compromise solution

The OxyExact’s sophisticated, flexible design ethos ensures it can be precisely configured to a wide range of application environments.

A single intuitive use controller can be situated in either a safe area or hazardous area, linking to up to six transmitters, permitting simplified set-up and ongoing maintenance through auto-validation and calibration procedures (direct interaction can be faciliated by optional software). The OxyExact also features a three enclosure design that allows the flexibility to measure flammable gases for 0-100% O2, helping to reduce costs by removing the need for purge gases.

Flexible performance you can depend on

The OxyExact uses patented Paramagnetic sensing technologies to deliver highly stable and accurate O2 measurements. Safety-enhanced design and optional flow alarm and pressure compensation ensures sampling versatility – including flare stack applications – that is demanded by your application needs. In addition, Ethernet or RS485 Modbus protocols deliver enhanced communications capabilities. All these aspects combine to make the OxyExact an industry leading solution for O2 analysis.
