Extend Freshness, Reduce Waste
Revolutionize Food Preservation with Bluezone® by Middleby
With the help of our exclusive partner, Bluezone®, Thermo-Kool is redefining food safety and waste reduction in cold storage.
Unlike standard filters that trap contaminants, Bluezone eliminates mold, ethylene, odors, and bacteria. Which, when used paired with Thermo-Kool walk-in coolers, helps to extend the shelf life of food, keeping storage environments cleaner and helping foodservice businesses maintain fresher ingredients and safer kitchens.


How Bluezone Works
1. Bluezone systems use ultraviolet (UV-C) light to break down airborne contaminants to eliminate 99.99% of viruses, bacteria, mold, and volatile organic compounds (VOCs), ensuring purified air without the use of chemicals or filters.
2. Bluezone by Middleby features a 30 CFM airflow rate for continuous air purification, a plug-and-play design for effortless installation, and low-maintenance operation, requiring only periodic UV lamp replacements.
3. Model 2400 handles large refrigerated spaces, while the Model 300 is ideal for smaller walk-ins and reach-ins. Both offer plug-and-play setup and low-maintenance operation for reliable air purification.
Smarter Storage. Fresher Results.
Extend Shelf Life
Bluezone technology removes ethylene gas, mold, and bacteria from the air, slowing ripening and spoilage. Maintaining a cleaner walk-in environment helps reduce food waste, improve product quality, and ensure fresher ingredients, without chemicals or costly filter replacements.
Reduce Food Waste
By removing ethylene gas and airborne contaminants, Bluezone helps prevent premature spoilage, keeping produce and perishable items fresher for longer. With less food waste, operators can cut costs, improve inventory management, and maintain higher-quality ingredients.
Eliminate Odors
Bluezone neutralizes odor-causing bacteria and volatile organic compounds (VOCs), ensuring a cleaner, fresher environment. Unlike masking agents, it actively removes odors at the source, improving air quality in walk-ins, reach-ins, and other food storage areas in commercial kitchens.


Freshness with Bluezone
Proven Freshness for Days
A controlled study tested Bluezone’s ability to extend the shelf life of strawberries over 10 days. The result? Strawberries stored with Bluezone had significantly less mold growth, slower ripening, and reduced odors compared to those stored without it.
By actively removing ethylene gas and airborne contaminants, Bluezone helps maintain freshness, improve product quality, and reduce food waste, ensuring strawberries stay visually appealing and more edible for longer.
