Perfect for the treatment of higher flows.
The UV system Dulcodes A has a compact design. Output-optimised medium pressure lamps ensure effective disinfection of potable water and the photochemical breakdown of oxidants and/or combined chlorine Mono-, di-, trichloroamine. The measuring result of type CLE (free chlorine) is subtracted from the ... more in the glossary.
The system is fitted with electronic ballasts, which continuously adjust the lamp output, either via an external signal, such as the flow rate, or by specification of a setpoint.
A long-term stable UVC sensor ensures that the system operates safely and reliably. The motor-driven automatic wiper efficiently cleans the lamp protection tubes and minimises maintenance work with types of water that have a tendency to form films. After comprehensive certification and biodosimetric validation, the systems comply with strict internationally recognised NSF, UL, CSA and USEPA standards.
Your benefits
- Simple installation, thanks to the compact inline system, ensures minimal installation work and fast retrofitting
- Maximum flexibility with installation, thanks to the free choice of fitting position and direct installation in plastic pipes, as no UV radiation escapes from the reactor
- External power control via 0/4 - 20 mA standard signal for optimum adaptation of the system to changing operating conditions, such as flow fluctuations
- Automatic adjustment of the lamp output to a defined UV-C sensor signal with power increase to a raised, adjustable sensor signal via a digital input saves energy and extends the lamp service life.
- Unbeatably simple and quick maintenance: all maintenance work can be carried out quickly and conveniently from one side.
- Certified systems: NSF 50, CSA 22, UL508, comprehensively biodosimetrically validated to UVDGM 2006
