OSRAM Puritec HNS 36W G13 - UV-C 254 nm germicidal lamp (OFR, ozone-free) for disinfection of air, water and surfaces

The OSRAM Puritec HNS 36W G13 is a low-pressure UV-C germicidal lamp (low-pressure mercury technology) designed for effective chemical-free disinfection . It emits radiation with a dominant wavelength of 254 nm ( OFR version, ozone-free ) and provides a UV-C radiated power of approximately 15–15.7 W in the 200–280 nm range, making it suitable for air purification systems in HVAC ducts, surface disinfection chambers, and water treatment equipment. With a T8 form factor, G13 base, 26 mm diameter , and 1200 mm length , it integrates easily into professional equipment using electronic ballasts for 18–40 W linear lamps. Its rated lifespan is 8,000 hours , and the special housing blocks ozone-generating wavelengths, ensuring reliable and environmentally friendly operation.

Product benefits

• Chemical-free disinfection : effectively inactivates microorganisms (bacteria, viruses, fungi) without generating chemical byproducts or ozone.
• Efficiency and reliability : high UV-C radiation at 254 nm with emission maintenance thanks to the internal coating.
• Easy integration : standard T8 (G13) dimensions and compatibility with common 1×18–40 W electronic ballasts.
• Optimized operating cost : long nominal life and robust design for continuous operation.

Use cases

• Air purification : UV-C chambers in HVAC ducts, fan-coil units and shielded portable equipment.
• Water treatment : closed UV-C reactors for industrial water, processes and ornamental fountains.
• Surface disinfection : UV-C tunnels or cabinets for tools, tapes and materials not sensitive to UV.

Frequently Asked Questions

Does it generate ozone? No. The OFR version blocks the wavelengths that produce it, so it is ozone-free .

Can it be used with people present? No. UV-C radiation can cause skin and eye damage. It should only be used in enclosed or shielded equipment with controls that prevent any direct or reflected exposure.

Is it dimmable? No. It is not designed for dimming.

Which ballast do you need? Electronic ballast for 1×18–40 W linear lamps compatible with T8 (for example, models from the OSRAM QTP-OPTIMAL 1×18–40 family). Always check equipment compatibility.

Installation and safety

• Use only in enclosed or shielded devices , with interlocks and/or sensors according to regulations.
• Avoid all exposure of skin and eyes to direct or reflected UV-C radiation; use appropriate PPE during maintenance.
• Respect polarity and ferrules; do not touch the tube with bare hands to avoid contaminating the surface.
• Manage as waste in accordance with current regulations due to mercury content.
