The Shinoe HVAC Purification Series

Biological fouling of indoor fin and tube heat exchangers, particularly air conditioner evaporators, is a key contributor to decreased capacity and efficiency and overall energy use and peak electricity demand.This biological fouling acts as an insulator and reduces heat transfer in the HVAC system.To maintain the building at the desired temperature , the fans have to work harder.The chilled water temperature may be lowered, making the chiller and compressor work more, resulting in increased energy costs.Air conditioning is the largest user of energy in commercial and institutional buildings and the largest user of energy within the air conditioning system is the chiller plant.In fact,HVAC systems account for an estimated 40-60% of energy use in buildings.The importance of UVC as an effective engineering tool in combating fungal and microbial growth in air conditioning systems and maintaining clean Cooling coils has even prompted ASHARE to include a chapter on “Ultraviolet Lamp Systems” in the 2008 ASHARE Handbook and a chapter on “Ultraviolet Air and Surface Treatment”in the 2011 ASHARE Handbook.


The heat conductivity of aluminum is approximately 200  W/mk while that of biofilm is approximately 0.2 W /mk.As conductivity has fundamental implications on heat transfer,clean coils devoid of biofilm offers significant efficiency advantages (Abstract from Refrigeration & Air Conditioning,Stoecker,W.F.,Jones J.W.McGraw Hill,NY.)



Shinoe HVAC Purification Series consist of 3 main technologies providing a total solution to the Indoor Air Quality (IAQ) The aluminium catalyst which activated by the UVC light remove odour gases such as VOC.The UVC lamp which emit UV on the surface of the cooling coil prevent the biofilm growth and maintain the optimum efficiency while the Shinoe Tech Ionizer (STI) help to neutralize the airborne particles.:Prolonged exposure to UV radiation will keep the air conditioning coil clean and free of bio-contaminants,including viruses, fungi, bacteria & bio-film that may grow on the coil. Maintaining a coil free of microbial growth will maximize the efficiency of coil heat transfer and reduce the hours of operation of the compressors, resulting in lower energy costs.



To destroy mold & bio-film on the evaporator coil and surrounding areas and to limit the spread of pollutants distributed by the HVAC systems.Maintain peak system efficiency ,lower energy costs & reduce conventional coil cleaning as well as eliminating biological “blow-off” & odors that can be introduced into the building or facility as a result of a fouled coil.


  • Lower HVAC operational costs by improving heat transfer and increasing net cooling capacity

  • Continuously clean coils, drain pans, plenums and ducts, reducing or eliminating costly cleaning programs and the use of harmful chemicals and disinfectants.

  • Reduce surface and airborne microorganisms such as mold, bacteria and viruses.

  • Reduce unpleasant, harmful odors associated with mold and bacterial growth

  • Improve general IAQ for better productivity and less absenteeism

  • Recommended by ASHARE
