PURION DUAL ULTRA DUAL OPD Ultra monitoring option ================================== **Integrated control with a control box with UVC intensity monitoring and additional technical backup mechanism.1** ![dual_opd_ultra](https://www.purion.de/fileadmin/_processed_/9/8/csm_dual_opd_ultra_8b046634ea.jpg) In the DUAL OPD Ultra version of the PURION DUAL product range, both systems are operated or switched simultaneously. A separate UVC intensity monitor (OPD 2) is integrated for both systems. Both systems are equipped with a potential-free contact. This is used to control the solenoid valve. In the event of a fault or if the UVC intensity of at least one system is too low, the water flow is automatically interrupted immediately by the solenoid valve.2 This technical backup mechanism achieves a particularly high level of safety. The control unit is integrated with a control box. The power supply is 230 V 50 Hz. The DUAL OPD Ultra variant enables technically sophisticated protection to ensure guaranteed sterilisation performance. 1 Indication of whether systems are in operation - no indication of whether guaranteed sterilisation is ensured. ² The water flow can only be re-enabled once the source of the fault has been rectified. **Technical Data** | Manufacturer | PURION GmbH | |---|---| | Type | DUAL OPD Ultra | | Number of Control Boxes | 1 | | Control Box Dimensions (W x H x D mm) | 250 x 350 x 100 | | Indicator Lights for Operating Status | 2 | | Indicator Lights for Disinfection Performance | 2 x OPD | | Additional Equipment | Included Magnetic Valve - electrically pre-assembled | | Electrical Connection | 110-240 V 50/60 Hz 12 V DC | | External Protection | 10 A (110-240 V AC) 6 A 12 VDC | **Application of the OPD Ultra Version:** | PURION 1000 110-240V | PURION 2500 H | |---|---| | PURION 1000 12V | | | PURION 2500 36W | | | PURION 2500 90W | | **Advantages:** - Included and electrically pre-assembled magnetic valve - Highest reliability of disinfection performance through the combination of UVC intensity monitoring (2 x OPD 2) and technical backup mechanism (magnetic valve) - Control electronics integrated in a control box - Cost-effective acquisition **Download Datasheet** [Datasheet Monitoring PURION DUAL OPD Ultra](https://www.purion.de/fileadmin/user_upload/user_upload/pdf/english/data_sheets/sensors/MONITORING_PURION_DUAL_OPD_Ultra_DS_EN.pdf) --- Further product portfolio =========================== - [![](https://www.purion.de/fileadmin/_processed_/b/2/csm_opd_e522090a72.jpg)](https://www.purion.de/en/bereiche/wasser/ausstattung/sensor-and-time-monitoring/)### [ SENSOR AND TIME MONITORING ](https://www.purion.de/en/bereiche/wasser/ausstattung/sensor-and-time-monitoring/) Sensors and monitoring options [ More ](https://www.purion.de/en/bereiche/wasser/ausstattung/sensor-and-time-monitoring/) - [![](https://www.purion.de/fileadmin/_processed_/e/2/csm_DVGW_79a576c1bb.png)](https://www.purion.de/en/areas/water/equipment/purion-dvgw/)### [ PURION DVGW ](https://www.purion.de/en/areas/water/equipment/purion-dvgw/) DVGW-certified drinking water UVC systems [ More ](https://www.purion.de/en/areas/water/equipment/purion-dvgw/) - [![](https://www.purion.de/fileadmin/_processed_/b/c/csm_pool_karusell_3f45c91fac.jpg)](https://www.purion.de/en/areas/water/topics/pool/)### [ Pool ](https://www.purion.de/en/areas/water/topics/pool/) Systems for large and small pools.
