UV Sterilisers

D-D have a complete range of Professional U.V. Sterilisers for every size of aquarium.

The use of type C ultraviolet radiation (UV-C) is the most effective way to sterilise water. No chemicals are involved and there is no risk of dangerous overdosing. Long process times are not required as sterilisation is instantaneous.

Many people are aware that quartz is 96-98% transparent to UV-C and that normal glass reduces its transmission by approximately 50%. This is why U.V. Sterilisers have a quartz sleeve between the water and the bulb. What many people are not aware of is that conventional UV sterilisers produce the UV radiation from a conventional glass U.V. tube therefore half of the intensity is lost before it even leaves the generation source.

The D-D Professional UV Sterilisers feature a pure quartz bulb as well as a quartz sleeve so 98% of the UV-C produced is utilised which means in effect that the D-D Professional models produce approximately twice as much UV-C per watt than a conventional unit with a glass bulb.
