High-Output Lamp Configuration is available for all our types and these lamps will deliver up to 80% higher UV output than standard units. They can be fitted with the standard H-O filament or our long-life electrode.

  • High-Output Filaments are usually operated at higher current – between 600 and 1200 mA.
  • Long-Life Filaments are of a single piece construction, offer greater durability and help to reduce the occurrence of premature burnout. They also generate higher UV output than the conventional type.

INDIUM AMALGAM LAMPS

Our Amalgam Lamps deliver up to three times the UVC output of the standard low-pressure UVC types and are a cost- effective alternative to the medium-pressure lamps. They are designed to operate efficiently at higher operating temperatures than standard and H-O lamps, thus delivering greater efficiency and / or requiring lower initial equipment cost. The main features include:

  • Greater stability of UVC output over varying temperatures.
  • Increased UV dosage at given size of the chamber / channel.
  • Higher efficiency =  fewer lamps needed = lower initial equipment costs for the whole system.

Note :     

UV output is measured under laboratory conditions at 253.7 nm for the period of 100 hours. (Actual output in the plant may somewhat vary depending on the actual operating conditions.)

Total length is measured between the outer edges of the bases, but not including electrical contact pins.

QUARTZ SLEEVE FABRICATION

Our sleeves are manufactured from 99.9% pure fused quartz. This material allows maximum transmission of the UV rays and provides increased wear resistance.

Quartz sleeves – main features:

  • Available in a wide variety of lengths and diameters.
  • Cut to the required lengths.
  • Bent, polished, spliced, flared – as per requirements from individual customers.
  • Other additional production operations are also available upon request.

ADDITIONAL INFORMATION

LONG-LIFE COATED LAMPS versus STANDARD UNCOATED – COMPARISON:

We also offer a full range of the germicidal lamps with internal coating. This coating functions as a barrier between the mercury vapours and the internal surface of the lamp tube, making the lamp more resistant against “solarization” (= darkening) thus resulting in the following benefits for the customers:

  • Extended life and more constant performance over the whole life of the lamp.
  • Higher UVC output and intensity toward the end of life cycle.
  • Reduced mercury content.
  • Lower equipment costs by lower number of lamps required.

VALUE-ADDED SERVICES FOR OUR CUSTOMERS:

  • PROPRIETARY PLASTIC / CERAMIC BASES – We have accumulated a wide range of tooling for the standard plastic and ceramic bases, so it is highly likely that we already have the configuration you’ve been using. In addition to this, we are able to design and produce any new types of bases you may require. Our in-house capabilities allow us to:
    • Easily and effectively determine each specific product.
    • Match the required pin configuration.
    • Substantially reduce the lead-time from the initial design to actual production.
  • MARKING OF LAMP TUBES – As a standard, we etch each lamp tube with a code showing the date of manufacture and caution remark. If you require any additional markings, please let us know.
  • MARKING OF LAMP BASES – Each base can be marked with a variety of information, e.g. logo, product number, country of origin, re-reorder information, etc. For the ceramic bases we use single or multi-colour onlay bonded onto the base at high temperature, resulting in durable and clear marking and very good product appearance.
