Description

Uniclean 900 Electro-pneumatic controller | For automatic cleaning | Ex | Corrosion-proof coating

The electro-pneumatic controller for fully automated pH measurement and cleaning

  • operation in hazardous locations Zone 1 (all system components)
  • corrosion-proof (powder-coated steel)
  • consistent enclosure concept for all devices
  • modular design, adaptable to virtually every measuring task
  • easy assembly and retrofitting
  • low maintenance effort due to innovative pump technology and extremely low consumption of media
  • time-controlled cleaning
  • cleaning with water and additional cleaning solution
  • reduced maintenance effort due to automatic cleaning
  • no disruption of production for cleaning the sensor
  • longer sensor life due to short-time measurement and regular cleaning
  • immediate readiness for measurement after production interruption since sensor is safely stored in liquid
  • safety ensured by monitoring of the compressed air and water supply, the probe position and the cleaning solution level

In combination with the Protos process analysis system and a SensoGate or Ceramat sensor lock-gate, Uniclean provides the ideal functionality of a complete system for automatic process control of a pH measurement.

Maximum availability of the point of measurement: Cleaning without disrupting the process, even when measuring directly in the pressure vessel.

Since the sensor is not removed for cleaning, the process can continue uninterrupted. This allows problem-free measurements in a pressure tank or in the main pipe. Elaborate and lockable bypasses are eliminated and accuracy increases.

Low maintenance
Fully automatic sensor cleaning with water or special cleaning solution in user-defined intervals without interrupting the process. The cleaning solution is automatically pumped into the cleaning chamber. Only the containers need to be refilled.

Cost-effective
Low-wear and low-maintenance pumps with extremely low consumption of cleaning agent.

Long sensor life also in critical processes
When measuring in aggressive media or at high process temperatures, the sensor rests in the cleaning chamber and is only briefly moved into the process for measurement. The cleaning chamber may be filled with water. This method increases the sensor life significantly.

Safe and easy measurement even in strongly polluted media
Sensor cleaning and rinsing is performed at user-defined intervals. Cleaning solution and water are automatically pumped into the rinsing chamber. Dismantling and manual cleaning of the sensor are omitted.

Modern fieldbus integration
The interfaces to PROFIBUS PA or Foundation Fieldbus allow the Uniclean system to be integrated directly in a fieldbus network. Naturally also in hazardous locations.

Universal adaptation to retractable fittings
The modular structure of the Uniclean system allows any retractable fittings to be used. Optimum functionality is achieved with the Ceramat and SensoGate sensor lock-gates.

Highly accurate measurements
The Uniclean 900 system allows highly accurate measurements to be taken even under difficult process conditions such as high pressure, high temperatures, and high levels of impurities. The device can be installed next to the process, within the hazardous area. Control is via the Protos 4400 measuring system or directly via a PLC.

Clean and safe construction
All features for smooth, safe, and low-maintenance operation are included as standard: Water pressure gauge, air filter and water trap, flooding sensor in the housing with alert message.

We look forward to hearing from you!
