Dr. Carl helpful translation on UVC for Produce:
- Fresh produce accounts for 17% of all foodborne pathogen outbreaks, totaling over 3000 outbreaks in the last ten years.
- UVC is effective against bacteria, viruses, and parasites found on fresh produce.
- UVC treatment does not diminish sensory quality of most foods and may extend shelf life.
- Optimal UVC dosage depends on surface characteristics; smoother surfaces require less dose.
- UVC combined with other sanitizing practices increases efficacy and supply chain safety.

Dr. Carl helpful translation for On-Coil UVC for HVAC:
- On-coil UVC treatment offers net energy savings, reduced labor, less chemical use, improved indoor air quality, health benefits, and overall comprehensive savings.
- Continuous UVC application according to ASHRAE standards can significantly lower respiratory infections and enhance HVAC system efficiency.
UV-C surface disinfection technology is essential in settings like healthcare and food production, where cleanliness is critical. By deploying UV-C light, this method efficiently disinfects surfaces, reducing the risk of pathogen transmission. It complements traditional cleaning methods by offering a rapid, chemical-free solution that leaves no residue. Ideal for high-touch areas, UV-C surface disinfection is key in maintaining hygiene standards, supporting modern infection control practices across various industries.
