Cold Chain Transport
Vehicle Disinfection
Guarding the Last Mile of Food and Pharmaceutical Safety in the Cold Chain! Air Guard's FLE Dry Fog Disinfection Solution — corrosion-free, ultra-dry nano technology that comprehensively eliminates mold crises in refrigerated compartments and air conditioning systems.
With the explosion in demand for fresh e-commerce, low-temperature food, and precision medical supplies, the hygiene and safety of cold chain logistics has become a major focus for businesses and consumers alike. Air Guard's solution creates a brand-new protection network for cold chain logistics operators that is both highly effective at killing bacteria and environmentally friendly.
Traditional Chemical Disinfection Damages Equipment? Natural Thymol Becomes the New Savior
Traditional Chemical Disinfection Corrodes Expensive Equipment
Traditional cold chain compartment disinfection often relies on chlorine-based chemicals (such as bleach) or chlorine dioxide. High-frequency use of these agents easily releases free acids, which oxidize and corrode:
- —Refrigerated compartment walls and stainless steel rails
- —Electronic panels and control systems
- —Expensive cooling units and evaporator blades
This ultimately shortens equipment lifespans and drives up operational costs significantly.
FLE & FLE-G: Natural Thymol Formula
Air Guard's dedicated disinfection solution FLE (and its heavy-duty automotive version FLE-G) uses natural thyme essential oil (Thymol) as its primary active ingredient. It contains absolutely no chlorine and produces no corrosive gases after high-temperature vaporization.
Proven to eliminate up to 99.99% of bacteria and viruses. Safe and non-toxic — will not affect sealed food or pharmaceutical products carried in the vehicle.
Exclusive 3D Nano Dry Fog Technology
Penetrates AC Ducts with Zero Freezing and No Moisture
Evaporators and air conditioning ducts in cold chain vehicles remain damp for long periods, making them prime breeding grounds for mold and odors. Air Guard's fogging machines transform the FLE disinfectant into a 3D nano dry fog with an average particle size of less than 0.5 microns.
This dry fog diffuses through Brownian motion, following the internal air conditioning circulation deep into the hardest-to-reach cooling fins and duct corners.
Ultra-Dry Microparticles — No Condensation in Frozen Compartments
Thanks to its ultra-dry microparticle characteristics, the fog does not condense into water droplets when used inside sealed, low-temperature refrigerated compartments.
This completely eliminates the risk of compartment icing or cardboard box damage caused by residual moisture — a critical advantage over traditional wet-spray methods.
14–30 Day Antibacterial Protective Coating
Once the dry fog settles, it forms an antibacterial protective coating on surfaces that lasts for 14 to 30 days, achieving long-term bacterial suppression and odor removal. Unlike one-time chemical treatments that offer no residual protection, AG's nano coating continues to work between treatment cycles — reducing treatment frequency and operational cost.
Flexible Machine Configurations — All Cold Chain Vehicle Types
Wireless Lightweight Model
Ideal for drivers of small 3.5-ton refrigerated trucks. Perform a quick 3-to-5-minute routine fogging disinfection before each departure or after unloading — no technical expertise required.
Professional Automotive Models
Ideal for medium-sized refrigerated box trucks. Equipped with a timed, quantitative dispensing function, it completes deep disinfection of the entire vehicle and air conditioning system with a single click.
Large Semi-Trucks & Containers
Ensures the nano dry fog completely fills every blind spot in the cargo hold through multi-point or sequential fogging — comprehensive coverage regardless of compartment size or layout.
Safety Lies in
Control
During Transit.
The FLE Dry Fog Disinfection Solution not only protects consumer health but also safeguards expensive vehicles and refrigeration assets for logistics operators.
It is the premier choice for upgrading to green and secure cold chain logistics — combining 99.99% pathogen elimination, zero equipment corrosion, zero moisture residue, and up to 30-day lasting protection in a single automated cycle.
