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.
The highly concentrated UV-C energy exerts a lethal effect on living organisms. It alters the genetic material (DNA) and inhibits their reproduction capability. The germicidal properties of UV-C radiation are therefore extremely beneficial in destroying bacteria, viruses, protozoa, algae, yeasts and mould spores. Different pathogens require different radiation levels to be neutralised; intensity can be increased by reducing flow rate through the unit for greater contact time.
Transmission Loss
Quartz is 96–98% transparent to UV-C while normal glass reduces transmission by approximately 50%. Conventional sterilisers using a glass tube lose a significant portion of UV output before it leaves the lamp. These professional UV sterilisers feature a pure quartz bulb combined with a quartz sleeve so the vast majority of produced UV-C is utilised. In effect, these models deliver substantially more UV-C per watt than conventional glass-bulb units, making them compact and easier to fit into many aquarium cabinets.
Features
- Slimline high-intensity quartz bulb with ceramic cap for good thermal insulation.
- Lamp life of 9000 hours for continuous use.
- Electronic ballast for flicker-free operation, doubling bulb life and ensuring stable UV output.
- Pure quartz sleeve prevents thermal shocks and maintains the lamp at the correct temperature for maximum UV-C output regardless of water temperature.
- Reinforced UV-resistant plastic body prevents degradation with time.
- Single-ended design and waterproof insulation to CE IP67 allow partial submersion in a sump, reducing cabinet space requirements.
- Viton gasket for a long-term UV-resistant seal.
- Ballast and lamp function LED indicator for easy status checks.
- Units can be linked together to form banks using standard pipework for scalable aquarium filtration and water sterilisation.
Designed for both fresh and saltwater aquaria, these UV sterilisers provide reliable, chemical-free water treatment that helps maintain clear water and healthy livestock by targeting the microorganisms that cause disease and water quality problems.
