Places like laboratories, Biosafety Level 3 (BSL-3) facilities, Good Manufacturing Practice (GMP) facilities, animal breeding facilities and production rooms where aseptic preparation are handles requires clean and sterile environment in their daily production. Meanwhile place like healthcare facilities and hospital where the places are prone to secondary infections and viral transmission also requires sterilization.
What is sterilization?
Sterilization is a process to destroy any living form on or in an object which includes bacteria, viruses, spores and fungi. From a microbiological point of view, a substance is sterile when it is free from any form of living organism.
However, it is not possible to achieve free form of microorganism but is possible to reduce to low number. Since the nature of microbial death is described by exponential function, therefore a sterilization is achieved through reduction of spore population of six log reduction (10-6).
Types of sterilization
Sanitation
A process of removal dirt and other soils without killing microorganisms or spores through chemicals such as detergent which usually achieve two log reduction (10-2).
Disinfection
A process that can destruct pathogenic microorganism but not bacterial spore which usually achieve five log reduction (10-5).
Sterilization
A process that can destroy all microbial living including spore and achieve six log reduction (10-6).

We use Double Jet Nozzle Dry Fog Hydrogen Peroxide (DDHP) Technology that produce finer particles in the form of Superior Dry Fog. As the finer the particles which is less than 1 μm, are less affected by gravity. Therefore, the lightweight particles allow wider sterilization space and shorter time.
When the DDHP is placed in the room, our technician will program the recipe for the room decontamination according to the room size. The room is then properly sealed to avoid leakage through the window, door or AHU. Once the room is sealed, the DDHP unit will then inject Superior Dry Fog to fill in the room and allow the fog to stay in the room to certain period before aeration start for H2O2 removal to safe concentration at 1 ppm.
It is very much dependent on the room size.
As the room size will define how long and how much H2O2 solution is needed to be injected into the room. Therefore, the cycle time varies according to room size.
Yes, it is safe. We use a superior, safe and environmentally friendly solution of hydrogen peroxide (H2O2) with concentration as low as 7.5%. With the low concentration H2O2 solution, it allows short ventilation time and subsequently a fast decontamination cycle. At the end of cycle, H2O2 breaks down to H2O (water) and oxygen (O2) molecule, leaving no residue, therefore it is safe for human and environment.
Moreover, our technical team will monitor the room H2O2 concentration level with H2O2 meter to ensure the concentration reach the safety level before allowing user to enter.
The low concentration H2O2 solution also safe to any time of surface material such as ABS, PVC, stainless steel, rubber, epoxy, cotton, nylon, wood etc. allowing the decontamination of the room can be done together with the equipment and furniture in the room without worrying damaging the equipment or the furniture. At the end of cycle, H2O2 breaks down to H2O (water) and oxygen (O2) molecule, leaving no residue, therefore it is safe for human and environment.
Moreover, our technical team will monitor the room H2O2 concentration level with H2O2 meter to ensure the concentration reach the safety level before allowing user to enter.
For each room decontamination, we will set up the biological indicator (BI) using Bacillus stearothermophilus, a type of bacteria strain that is most resistant to sterilization.
The BI is then place at the most difficult to reach area in the room and then is collected during the end of room decontamination before sending it to accredited laboratory for confirmation of sterilization.
Using this strain will be the most reliable way to validate the room decontamination efficiency.
