The D-D Professional Complete 20w UV Unit is a powerful and efficient sterilization solution for your aquarium. With its use of type C ultraviolet radiation (UV-C), it provides instant and effective water sterilization without the need for chemicals or the risk of overdosing.

Equipped with a slimline high intensity quartz bulb and ceramic cap, this UV unit ensures good thermal insulation and a long bulb lifespan of up to 9000 hours. The electronic ballast guarantees flicker-free operation, doubling the bulb's lifespan and saving you money in the long run.

One of the key features of the D-D Professional UV Sterilisers is the use of a pure quartz sleeve, which prevents thermal shocks and maintains the bulb at the ideal temperature (40-45 C) for maximum UV-C output, regardless of the water temperature.

Here are some key features and benefits of the D-D Professional Complete 20w UV Unit:

• Pure quartz sleeve for maximum UV-C output
• Reinforced UV resistant plastic body for long-lasting durability

The unit's single-ended design and waterproof insulation (CE IP67) allow for partial submersion in a sump, reducing the space required for installation. It also comes with a Viton gasket for a long-term UV resistant seal.

The D-D Professional Complete 20w UV Unit, with a flow rate of 1000 lts/hr, is suitable for aquariums ranging from 500 to 1000 litres in reef systems (1-2 times turnover per hour), and 250 to 500 litres in fish systems (2-4 times turnover per hour).
