OSRAM HNS 55 W G13 (PURITEC UV-C) - 254 nm OFR germicidal lamp for disinfection of air, water and surfaces

OSRAM HNS 55 W G13 (PURITEC UV-C) - 254 nm OFR germicidal lamp for disinfection of air, water and surfaces

The OSRAM HNS 55 W G13 is a low-pressure UV-C germicidal lamp ( T8 tube, Ø 26 mm) designed for effective chemical-free disinfection . It belongs to the PURITEC HNS family and emits radiation with a dominant wavelength of 254 nm in its OFR (ozone-free) version, thanks to a special glass that blocks the 185 nm line and prevents ozone formation. With 55 W of electrical power, 83 V nominal voltage, and a G13 base , it offers a typical UV-C radiated power of ~18 W , suitable for inactivating microorganisms in air, water , and surface purification systems. It incorporates a specific coating that extends its lifespan and maintains stable UV-C emission over time. It is not dimmable and can be installed in any working position . Tube length: 895 mm . Approximate weight: 145 g . Nominal lifespan: 8,000 h . Use only on equipment prepared for UV-C and with adequate protection.

Product benefits

• Efficient disinfection without chemicals , ideal for purification processes and microbiological control.
• Ozonofree (OFR): the special glass suppresses ozone generation, facilitating integration into closed systems or with controlled extraction.
• Stable UV-C emission and extended life thanks to the internal coating.
• Standard T8 format with G13 base, easy replacement in compatible equipment.
• Versatile installation due to its universal working position.

Use cases

• Air purification in HVAC ducts, upper-room lamps and stand-alone units with UV-C shielding.
• Water treatment in quartz jacketed equipment (aquaculture, fountains, reservoirs, industrial equipment).
• Disinfection of surfaces in chambers, transport tunnels, laboratories and industrial processes.
• Sanitary and industrial applications where microbiological control without chemical residues is required.

Frequently Asked Questions

• Does it generate ozone? No. The OFR version blocks the 185 nm line responsible for ozone formation.
• Can it be used with people present? No. UV-C radiation can damage skin and eyes. Always use enclosed housings, shielding, interlocks, and signage.
• Does it need a ballast? Yes, it requires electronic ballast for high-load T8 tubes. Compatibility example: QUICKTRONIC PROFESSIONAL QTP-OPTIMAL 2x54–58 (or other equivalent ECGs depending on the equipment design).
• Is it adjustable? No, it is not adjustable.
• How does it affect lifespan? UV-C emission decreases over time. Replace according to the equipment maintenance schedule or when irradiance falls below the target.

Installation and safety recommendations

• Integrate UV-C shielding , interlocks, and timers; follow the equipment manufacturer's instructions.
• In water treatment, use a clean quartz jacket and a maintenance plan to ensure optical transmission.
• Avoid dust or grease deposits on the tube; clean with a soft cloth and isopropyl alcohol when the equipment is disconnected and cold.
• Manage end-of-life according to regulations due to mercury content (low content).
