UV Air Disinfection — Ducts, Rooms & Surfaces
Keep air-conditioning coils clean and reduce airborne bacteria, viruses and mould with UV-C. Blaze Technology supplies in-duct systems, room air sanitizers, upper-room fixtures and mobile units in Singapore.
Blaze UV Air Disinfection
In-duct UV for air-conditioning systems, room air sanitizers, upper-room UV and a mobile unit for room and surface disinfection. All models 220–230 V.
UVD In-Duct UV Systems — for AHUs, FCUs and ductwork
Mounted through the duct wall, UVD units irradiate moving air and keep cooling coils and drain pans free of mould and biofilm. Cleaner coils also help airflow and energy use. Choose the length closest to your duct width.

UVR Room Air Sanitizers — free-standing, wall or ceiling
A fan draws room air through a closed UV chamber, so people can stay in the room while it runs. For clinics, waiting rooms, offices, classrooms, gyms and food rooms.
| Model | UV lamps | Room volume at 1 air change/h | at 3 air changes/h | at 6 air changes/h | Size H × L × W (mm) |
|---|---|---|---|---|---|
| UVR-180 | 2 | 178 m³ | 59 m³ | 30 m³ | 197 × 876 × 197 |
| UVR-550 | 4 | 554 m³ | 185 m³ | 92 m³ | 305 × 1,202 × 356 |
UVU Upper-Room UV Fixtures — indirect air disinfection
Wall-mounted louvred fixtures direct UV-C into the upper part of the room, above head height, while room air circulates through the UV zone. Suits occupied spaces with high ceilings.
| Model | UV lamps | Power | UV-C output | Size L × W × D (mm) |
|---|---|---|---|---|
| UVU-1 | 1 | 31 W | 8.5 W | 610 × 136 × 200 |

UVP-8 Mobile UV Room and Surface Sanitizer
Eight UV-C lamps on a wheeled stand for fast disinfection of empty rooms and surfaces: clinics, labs, hotel rooms, cleanrooms and vehicles. Use only in unoccupied rooms.
| Model | UV lamps | Size H × L × W (mm) | Use |
|---|---|---|---|
| UVP-8 | 8 | 1,740 × 552 × 508 | Unoccupied rooms and surfaces |
A remote-controlled version is available on request.
Using UV-C Safely
UV-C light harms skin and eyes. In-duct systems and room air sanitizers keep the UV inside the equipment. Upper-room fixtures aim UV above head height. Mobile units and open fixtures must only run when the room is empty: we supply door interlocks, motion sensors and warning signs to make this automatic.
Frequently Asked Questions
Why put UV inside an air-conditioning system?
Cooling coils and drain pans stay wet, so mould and biofilm grow on them. UV-C aimed at the coil keeps it clean, which helps airflow and heat transfer and cuts musty smells and cleaning work.
Which in-duct model fits my AHU?
Choose the unit whose length into the duct is closest to the inside width of the duct or coil face. Send us the AHU or duct size and airflow and we will recommend the model and number of units.
Can people stay in the room while UV runs?
Yes with room air sanitizers (the UV is enclosed) and correctly installed upper-room fixtures. Mobile units and open UV fixtures must only be used in empty rooms.
How often are the lamps changed?
Usually once a year for continuous use. Blaze stocks replacement lamps.
