Uniclean® 900 - Van London

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

Facts
– consistent enclosure concept for all devices
– modular design, adaptable to virtually every measuring task
– easy assembly and retrofitting
– hygienic version (polished stainless steel) or corrosion-proof (powder-coated steel)
– 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
– operation in hazardous locations Zone 1 (all system components)
– 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
