Evaporators can hugely benefit Specialised direct emitters. Biofilm build up on evaporator coils can result in poor performance of cooling devices as well as promoting recirculation of potentially Covid-contaminated Air. UV-C surface disinfection at the cooling coils is safe and is a rapid, low cost and proven intervention for these systems. Our UVC products can be retrofitted on to these units which will inactivate all harmful microbes, including SARS-CoV-2, on surface of the coils BUT IMPORTANTLY, whilst also disinfecting the air which is blown from the unit across the room, cold/chill store or factory. This system also improves food safety and public health and helps to prevent cross contamination and foodborne diseases. These systems can run 24/7 with people present, meaning that the air is constantly being disinfected. This ensures that your operation is safer, more covid-secure for your people, and significantly lower risk of operational disruption cause by a covid infection incident, part or full factory shut-down as a result.


  • Unwanted Micro-organisms generally.
  • SARS-CoV-2 ( Covid-19) now specifically
  • Growth of Biofilm
  • Loss of air flow and energy inefficiency
  • Risk of cross-contamination
  • Product quality and safety issues
  • Increased use of chemicals for cleaning


  • UV-C energy inactivates all known micro-organisms on surfaces and in the air (from molds to Coronavirus)
  • Improved workforce safety
  • Improved food safety and benefit for public health
  • Prevention of cross-contamination
  • Reduction of foodborne diseases
  • Reduced risk of operational disruption or factory close downs


Air conditioners and fans are often affected by biofouling due to condensate and microbe build up. This leads to:

  • Germ and Virus distribution in the building, risk of increased staff illness
  • Higher energy demand of plant appliance due to biofilm
  • The increased energy requirement is due to a poorer heat transfer at the cooling coils as well as an increased output of the fan, which has to convey the same volume flowthrough a smaller opening.

Fitting UV-C devices for evaporators is a simple integration in new and retrospectively, to existing units, to create a highly efficient ecological disinfection system.


  • Instant UVC disinfection 24/7
  • Constant low level microbial count
  • Secured operational safety
  • Minimised use of chemicals
  • Less cleaning costs
  • Less electricity costs


Highly versatile UVC systems enable to use multiple standard modular units for any size of evaporator.

In a study by Wang et al. (2016) the influence of a UVC installation on the energy demand of a evaporator was investigated. Installation not only improves the hygienic state of the evaporator, but it keeps energy consumption low and reduces operating cost.
