The new Afriso (Germany) Watchdog ÖWWG 3 oil/water alarm unit signals unwanted accumulations of water, fuel oil, diesel, motor oil, vegetable oil, transformer oil, as well as antifreeze agents, emulsion or oil-water mixtures. It is used to monitor heating connection rooms, oil storage connection rooms, water connection rooms, laundry rooms, drip trays, shafts, channels or pipes. ÖWWG 3 consists of a control unit and a flexible PTC thermistor probe. In the case of an alarm, visual and audible alarms are triggered and the unit is locked. The device is unlocked at the unit itself; however, unlocking is also possible externally from a distance of up to 100 m. The oil/water alarm is intrinsically safe and self-monitoring. Short-circuits and cable breaks in the probe cable are detected. In the case of a power failure, the de-energising output relay transmits a signal to additional devices or pumps. The unit can be integrated into existing communication and building control systems. The oil/water alarm unit is TÜVtested
and has the Technical Approval Z-65.40-339 of the German Institute for Building Technology (DIBt). To ensure perfect room monitoring and a maximum of operational safety, ÖWWG 3 can be connected to the AFRISO EMS 220 event reporting system. In the case of an alarm, the person in charge is immediately notified via the internet, e-mail, SMS or phone. Early detection of unwanted liquids can save private households a lot of hassle and money and prevent both companies and operators of industrial facilities disastrous accidents with potentially severe consequences to people and the environment.
