Permanent in-duct UV-C installation for continuous HVAC duct disinfection and biofilm prevention. Duct surfaces accumulate mould, bacteria, and biofilm over time — spreading through building ventilation. UV lamps mounted inside ducts irradiate duct walls and passing air continuously. Eliminates biofilm growth, prevents mould colonisation of ductwork, and reduces airborne microbial load throughout building. Particularly effective at cooling coil sections where condensation encourages microbial growth. Reduces sick building syndrome complaints and improves indoor air quality. CE certified, ISO 9001:2015.

Frequently Asked Questions
Low-pressure mercury UV lamps are rated for 9,000–12,000 operating hours (approximately 1–1.5 years at continuous operation). UV output degrades by 10–15% per year — replace when the UV intensity monitor reads below 70% of the initial calibrated value, or at least every 18 months regardless of intensity reading.
BIS IS 10500:2012 requires E. coli to be not detectable in 100 mL of treated water. A UV dose of ≥25 mJ/cm² reliably achieves this. Ozone India Technology UV systems are designed to deliver ≥40 mJ/cm² at end-of-lamp-life, providing a safety margin for variable water quality conditions.
No. UV disinfection is a purely physical pathogen inactivation process — it does not remove any dissolved or suspended contaminants. Water must be pre-treated to <1 NTU turbidity before UV treatment. For complete water purification including TDS, hardness, and chemical removal, combine UV with RO and/or ozone treatment.
UV systems are sized for specific UVT values. Ozone India Technology systems are standard-rated at ≥85% UVT (typical drinking water after filtration). For low-UVT water (coloured groundwater, post-secondary treated sewage at 60–70% UVT), the system is sized with additional lamp power to compensate. Provide your water's UVT% when requesting a quotation.
Yes. All UV water treatment systems carry CE marking under EU Machinery Directive 2006/42/EC and are manufactured under ISO 9001:2015 QMS. CE documentation supports export to EU, GCC, and other markets requiring CE certification for imported water treatment equipment.
