VHP HVAC Sterilization System
The CIGEAIR-HVAC series VHP sterilizer adopts flash vaporization technology, which vaporizes 30%-35% hydrogen peroxide and then quickly and evenly distributes it in the sterilization space through the HVAC system, realizing space 6LOG sterilization without dead end; after the sterilization, the hydrogen peroxide can be rapidly degraded with no residue and no toxicity. The system adopts modular design with four parallel groups of VHP generation modules to ensure the reliability of the system; the sterilization process is controlled by saturation and dew point to ensure the vaporization state of hydrogen peroxide. The overall equipment is made of stainless steel, which is smooth in appearance without dead ends; through the user-friendly operating interface, users can quickly master the operating skills; the system's project management and implementation team can provide services from design, production, installation, commissioning, parameter development to verification, and can complete turnkey projects in the field of pharmaceutical, biosafety, medical and public safety.

VHP Space Sterilization System adopts low-temperature flash evaporation technology, delivering Log6-level broad-spectrum sterilization with strong gas penetration and no dead zones. It features closed-loop intelligent concentration control and catalytic degradation for ultra-low residue and good material compatibility. Fully automatic operation with traceable sterilization data meets high-level validation requirements for GMP, P3 laboratories and pharmaceutical cleanrooms. Modular design adapts to spaces ranging from small enclosures to large workshops and full air duct sterilization.

Design Considerations
Control of hydrogen peroxide vaporization state throughout the sterilization process
Hydrogen peroxide generation: Ensure that the hydrogen bond is completely broken and flash evaporation is adopted
Hydrogen peroxide delivery: Fresh air temperature, humidity and air volume, pipeline preheating, and pipeline airtightness
Process control: Saturation, dew point control and cold point control
Coordination of HVAC system
Cyclic or non-cyclic
Disinfection mode: Dehumidification - cut off chilled water to restore room temperature - frequency reduction (about 10 times)
Air duct tightness - Material of air duct sealing ring (neoprene)
VHP delivery line requirements
Pay attention to geographical and seasonal variations
Pipeline insulation, sealing and corrosion resistance

FAQ
What if VHP generator fails to vaporize with no hydrogen peroxide vapor output?
What if VHP generator fails to vaporize with no hydrogen peroxide vapor output?
A: It is a fault of VHP generation unit. The generator cannot fully vaporize H₂O₂, no VHP enters HVAC circulation pipeline, and sterilization cycle cannot start normally.
What deviation will occur if H₂O₂ feed pump is abnormal and liquid supply flow is lower than setpoint?
What is the impact if trace heating of VHP pipeline fails and hydrogen peroxide condenses inside pipeline?
What consequence will occur when room relative humidity exceeds process window during sterilization?
What type of deviation is it if room temperature exceeds allowable range during sterilization?
