Evaporator disinfection

Evaporators can be the perfect living environment for microorganisms







Evaporators as source of infection

Evaporators are an ideal environment for bacteria and moulds. In the condensation water on the fins of your coolers microorganisms can grow and contaminate the passing air.

Within a few days a stable flora can grow on new evaporators. This flora can reproduce very well on cooling fins, also at low temperatures, and forms a slimy layer on the fins and in the drip pan called biofilm. Especially moulds and cold-loving organisms, like Listeria can multiply in evaporators.

UVC light

By installing a UVC lamp in or in front of an evaporator it will remain clear of biofilm. It improves the hygiene of the evaporator and will prevent the the drip pan to become a microbiological swamp.

The benefits of evaporator disinfection

  • Prevents spread of bacteria, moulds and yeasts through the air
  • Prevents clogging of the drip pan or drain
  • Reduces cleaning costs of your cold store
  • Improves cooling capacity

Bacteria free evaporators in air handling units

Air handling units can suffer from bacteria and moulds. The high humidity allows microorganisms to reproduce, they contaminate the air and reduce cooling capacity.

With installing UVC lamps in an air handling unit:

  • the air handling unit remains free of bacteria and moulds
  • the air quality increases
  • cooling efficiency improves
  • cleaning frequency can be lowered

How does UVC radiation work?

Ultraviolet is electromagnetic radiation, just outside that part of the light spectrum that is visible to the human eye.
The short-waved and energetic UVC radiation is absorbed by certain parts of the DNA which causes a photochemical change. This change affects the DNA and ensures that the microorganisms can not reproduce and die. UVC works an all microorganisms.
