Problem Statement
- Existing disinfection methods are slow and uncomfortable, reducing throughput and discouraging use in high-density areas.
- UV disinfection is limited by line-of-sight requirements and potential health risks.
- Ozone’s toxicity at high concentrations raises safety concerns for direct human exposure.
- Controlled ozone exposure requires precise monitoring and regulation to ensure safety while maintaining effectiveness.
- Disinfection processes need to be non-intrusive, comfortable, and efficient, protecting users while allowing rapid throughput.
Technology
Plasma-Based Ozonated Air Generation:
- Utilizes a plasma-based system to efficiently generate ozonated air, ensuring high effectiveness in disinfection.
Ozone Monitoring and Regulation:
- Incorporates ozone sensors and a control system to continuously monitor and adjust ozone concentration within safe levels, ensuring human safety during disinfection.
Air Curtain Partitioning:
- Implements an air curtain assembly to create a partition within the chamber, separating the head and body compartments to prevent direct exposure of the face and head to ozone.
Automatic Door System with Height Sensing:
- Features automatic sliding doors equipped with height sensors to detect occupants and ensure proper partitioning, enhancing user convenience and safety.
Efficient Ozone Decomposition:
- Utilizes an ozone decomposing unit to swiftly convert ozone into oxygen before releasing it into the atmosphere, minimizing potential health risks associated with ozone exposure.
Key Features / Value Proposition
Highly Effective Disinfection:
- Rapidly disinfects using ozonated air for thorough microbial inactivation.
Safety and Comfort:
- Ensures user safety with air curtain partitioning, height-sensing automatic doors, and preventing direct ozone exposure to the face and head.
Precise Ozone Control:
- Uses sensors and control systems to maintain safe ozone levels.
Efficient Operation:
- Features rapid purging and customizable settings for seamless disinfection processes.
Versatile Application:
- Suitable for high-density environments like markets, malls, hospitals, and public events.
