The EVD0000UC0 Ultracap module is an optional external backup device for the EVDEvo used to close the valves in the event of mains power failures. The module guarantees temporary power to the EVDEvo (single or twin) in the event of power failures, for enough time to immediately close the connected electronic valves (one or two).
Ultracap is the new emergency power supply device for electronic valves, the natural completion of the EVDEvo, range both single and Twin versions, ensuring complete closing of the valves even when there are sudden mains power failures. Exploiting ELDC (Electric Double Layer Capacitor) technology, Ultracap can supply immediate, reliable and clean emergency energy, representing a major step forwards compared to conventional battery-based systems, including as regards disposal of used materials. Ultracap has been designed to give 10 years’ trouble-free silent operation, without requiring periodical checks or having to replace the batteries. Ultracap means immediate energy: just 5 minutes (4 minutes for Carel valves) after power is restored, the system is already recharged and active (in practical terms the same time the compressor takes to restart…). The extreme reliability of Ultracap combined with the exceptional tightness of Carel valves, eliminates the need for solenoids valves even in the most critical applications.
