UV+IR PRODUCTS

Understanding the different applications is key to enabling the efficient use of UV light and IR heat. UV+IR Lamps Pty (Ltd) supply various accessories to maximise the efficiency of your UV or IR system. From Modular units, cooling fans, ducting , conveyor belts, lamp reflectors to Engineering advice and solutions.

QUARTZ TUBES AND SHEETS

Quartz glass tubes are manufactured in a very broad diameter range from 2 mm up to 900 mm. Tubes are manufactured from different material grades to suit client’s specifications.
Description
Having achieved the position of the world’s largest quartz producer, Heraeus Quarzglas looks back on innovations in quartz glass technologies and achievements dating back over 100 years. Heraeus develops, produces and supplies tailor-made solutions from base material to complex system components from one source. Heraeus Quarzglas provides transparent QUARTZ GLASS PLATES with very good transmission and opaque plates with high reflectivity. These glass plates are offered in a wide variety of grades, from cost efficient direct drawn plates, to plates cut from various solid materials.

REFLECTORS

We manufacture tailor-made reflectors from Polished Anodised Aluminium as well as diachronic Reflectors. Depending on the design of the reflector system, the effective primary radiation applied consists of approximately 50- 75% Primary radiation (from the lamp) and 25-50% secondary radiation (from the reflector).
Description
Dichroic reflectors are the easiest step to take to reduce heat to your substrate. These reflectors can be specified for your Fusion UV curing system.  Or, if you find your needs change, they can be easily retrofitted into an existing system.  Dichroic reflectors are exactly the same dimensions as a conventional reflector product, but they have 50 or more layers of a dielectric coating applied to their surface. This coating allows UV to be reflected, but absorbs much of the longer infrared (IR) wavelengths. The heat is then dissipated from the reflector surface by air-cooling.

There is little reflectance of visible or IR radiation. The total UV reflectivity can be very good for a well designed dichroic reflector. A comparison of the cure speed and surface temperature rise for a cure system with and without a dichroic reflector is shown in Table 5.

ELECTRONIC TRANSFORMERS

This high power, intelligent Electronic UV-lamp Transformer® was developed for UV-lamps from 2kW to 27kW.
Description
Combined with microprocessor technology, this high frequency switching power supply uses IGBT inverter technology in order to achieve the highest efficiency, high reliability, precise control and large energy savings. The UV+IR Electronic UV-lamp Transformer® replaces traditional electromagnetic transformers used in UV curing systems in the printing and surface coating industry.  The savings achieved in energy costs typically pay for the initial capital expenditure in less than 2 years.

Compact Design Weight is 20% of a conventional transformer
Volume is 15% of a conventional transformer

 

Upper Air Germicidal Sterilisation

Upper air Ultra Violet systems have been used to control airborne infectious diseases since the 1930’s, their use waned during the arrival and proliferation of antibiotics in the 1940’s. Demand for the technology increased following a resurgence of drug resistant infectious microorganisms, including tuberculosis, which requires additional infection control measures.

Description

Independent Studies and specialised applications have proven upper air treatment methods to be quite effective in the inactivating all forms of infectious agents. Typically installed on a wall at a height above 2.3m, the UV fixture employs louvers to direct the radiation upward and outward to create an intense zone of UVGI in the upper air while minimizing the dosage in the lower (occupied) portion of the room area.Independent Studies and specialised applications have proven upper air treatment methods to be quite effective in the inactivating all forms of infectious agents.

Applications:

  • Commercial Buildings – * Industrial Buildings
  • Health Care Facilities  – * Institutional Buildings

Benefits:

  • Improves indoor air quality by reducing bacteria, viruses and mold.
  • Reduces the risk of colds, flu, allergies and other airborne related common illness aswell.
  • Produces no Ozone or other secondary contaminants
  • Easy to install and maintain.

Surface Sterilisation

Germicidal Surface Sterilisation offers surface sterilisation without chemicals, which is critical in some industries. For example , in food processing, UVC can kill viruses, bacteria, yeast and fungi in seconds, hereby eliminating the need for harmful chemicals that could come in contact with food.

Description

This is increasingly being used for the surface sterilisation of filling equipment, conveyor belts, transport containers, working surfaces of foodstuffs, counter tops, and on liquid-sugar tanks to kill mold and bacteria.This is increasingly being used for the surface sterilisation of filling equipment, conveyor belts, transport containers, working surfaces of foodstuffs, counter tops, and on liquid-sugar tanks to kill mold and bacteria.

Heating

Heating and drying applications to suit your needs from smaal handheld units for single panels to overhead installation in spraybooths.

Infra Red Heat is used worldwide by the automotive industry because it provides you 100% control over the application and duration of the heat. Instant heat enables you to speed up the repair process.

This also improves the quality of repairs and reduces the need for polishing. Infra red heat is clean and safe, there are no pollutants or by-products that can negatively affect the health of your employees.
