Why UV-C lamps need scheduled care
A UV-C tube keeps glowing after it has lost output. The manufacturer notes that after the rated life the lamp still shines in the same purple-blue colour, but the ultraviolet intensity is lower and the treatment is less effective. For the in-duct HEP 36WPL/SPH model, the stated tube life is 18,000 hours.
What we can help with
- Operating-hour checks. Some models, such as the K72W/SP, count down the remaining tube hours with a sensor light. Exact hours are read by a trained service technician through the service connector.
- Tube replacement. Tubes are replaced only with the lamp disconnected from the power supply, and only by trained people.
- Cleaning and inspection of the lamp, grille and mounting, carried out by instructed persons.
- Spare lamps and parts for the models we supplied. Ask us about availability.
Disposal
Broken or damaged tubes contain mercury and must be disposed of as hazardous waste.
Frequently asked questions
How often should tubes be changed?
When the rated life in the manual for your model has passed, for example 18,000 hours for the HEP 36WPL/SPH. Send us the model and hours and we will advise.
Can we change tubes ourselves?
Only trained staff should, following the manual and with power disconnected.
