High efficiency decontamination service (H2o2).


Why Do You Need Sterilization?

Places like laboratories, Biosafety Level 3 (BSL-3) facilities, Good Manufacturing Practice (GMP) facilities, animal breeding facilities, and production rooms where aseptic preparation are handled require a clean and sterile environment daily production. Meanwhile, a place like healthcare facilities and hospitals where the areas are prone to secondary infections and viral transmission requires sterilization.

What is Sterilization?

Sterilisation is a process to destroy any living form on or in an object, including bacteria, viruses, spores, and fungi. From a microbiological point of view, a substance is sterile when free from any form of a living organism. However, it is impossible to achieve a free form of microorganism but is likely to reduce to a low number. Since the nature of microbial death is described by an exponential function, sterilisation is achieved by lowering the spore population by six log reductions (10-6).

Type of Sterilization


A process of removing dirt and other soils without killing microorganisms or spores through chemicals such as detergent, which usually achieve two log reduction (10-2)


A process that can destroy pathogenic microorganisms but not bacterial spore, which usually achieves five log reduction (10-5)


A process that can destroy all microbial living, including spore, and achieve six log reduction (10-6)

Why DDHP Decontamination?

We use Double Jet Nozzle Dry Fog Hydrogen Peroxide (DDHP) Technology that produces finer particles in Superior Dry fog. The finer the particles, which is less than 1 μm, are less affected by gravity. Therefore, the lightweight particles allow more expansive sterilization space and a shorter time.

Is DDHP Decontamination Safe?

Yes, it is safe. We use a superior, safe and environmentally friendly solution of hydrogen peroxide (H2O2) with a concentration as low as 7.5%. The low concentration H2O2 solution allows short ventilation time and a fast decontamination cycle. Furthermore, the low concentration H2O2 solution is 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. Moreover, our technical team will monitor the room H2O2 concentration level with the H2O2 meter to ensure the concentration reaches the safety level before allowing the user to enter.

What is The Process of DDHP Decontamination?

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 was then adequately sealed to avoid leakage through the window, door or AHU. Once the room is sealed, the DDHP unit will inject Superior Dry Fog to fill in the space and allow the fog to stay in the room for a certain period before aeration starts for H2O2 removal to safe concentration at 1 ppm.

How long Decontamination Cycle takes?

It is very much dependent on the room size. 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.
