Commercial road transport — from small vans to long-haul trucks — requires regular sanitary treatment. This is especially critical for food transporters: dairy products, meat, vegetables and fruits. Sanitary standards and HACCP requirements mandate maintaining cargo area cleanliness.
Ozonation is an effective and economical method of fleet sanitary treatment. One mobile ozonator treats 10-15 trucks per shift, runs from vehicle power, requires no consumables. For logistics companies, this is significant savings compared to chemical treatment.
Types of commercial transport
Ozonation is used for all types of freight road transport:
- Refrigerators — transport of perishable products with temperature control
- Insulated vans — product delivery without active cooling
- Curtain-sided semi-trailers — universal freight transport
- Solid-body vans — delivery to retail outlets
- Specialized vehicles — bread trucks, milk trucks, meat trucks
- Container carriers — with installed shipping containers
Sanitation problems in freight transport
Vehicle cargo areas are contaminated from various sources:
- Odors from previous cargo — fish, meat, chemicals, fertilizers
- Bacterial contamination — from leaking packaging, damaged products
- Mold and fungi — when transporting wet cargo, condensation
- Insects — brought in with cargo or from warehouses
- Dust and dirt — accumulate on floor and body walls
- Packaging residues — cardboard, film, tape, pallet strapping
Traditional washing and wiping do not fully solve the problem. Water does not kill bacteria, odors return, mold grows again. Disinfection is needed.
Truck treatment technology
Emptying the body
Unload cargo, remove trash and packaging residues. For heavy contamination — preliminary wet cleaning.
Ozonator placement
Install ozonator inside the body at maximum height. Connect to electrical network (220V/230V) or external source.
Sealing
Close doors, gates, hatches. For curtain-sided semi-trailers — lower curtain and secure.
Ozonation
Turn on ozonator, start timer. Treatment time 20-40 minutes depending on volume and contamination.
Ventilation
Open doors, turn on refrigerator ventilation (if available). Ventilate for 15-20 minutes.
Treatment modes by transport type
| Transport type | Body volume | Capacity | Treatment time |
|---|---|---|---|
| Light-duty van | 8-15 m³ | 5-10 g/h | 15-20 min |
| Medium-duty van | 20-40 m³ | 10-20 g/h | 20-30 min |
| Refrigerator (semi-trailer) | 80-90 m³ | 20-30 g/h | 30-40 min |
| Curtain-sided semi-trailer | 90-100 m³ | 20-30 g/h | 35-45 min |
| Tank truck (milk truck) | 5-20 m³ | 10-15 g/h | 20-30 min |
| Bread van | 15-25 m³ | 5-10 g/h | 15-25 min |
Refrigerator treatment specifics
Refrigerators and insulated vans require special attention — they transport food products with strict sanitary requirements.
- Treatment with refrigeration unit off — ozone does not affect refrigerant
- Good insulation tightness increases effectiveness
- Ozone does not damage sandwich panels and plastic lining
- Entire interior surface treated, including ceiling and floor grooves
- Odors absorbed into walls from previous transports are eliminated
Odor elimination
One of the main problems in freight transport — odors from previous cargo:
- Fish and seafood — persistent odor, absorbs into walls
- Meat — when packaging is damaged or temperature regime violated
- Onions, garlic — sharp odor, transfers to other cargo
- Chemicals — fertilizers, household chemicals, technical fluids
- Perfumes — strong aromas, incompatible with food cargo
Ozone oxidizes odor molecules, converting them to neutral compounds. This is not masking, but complete elimination. After treatment, the body smells fresh — "like after a thunderstorm".
| Odor type | Concentration | Treatment time | Efficiency |
|---|---|---|---|
| Light (dust, mustiness) | 10-15 mg/m³ | 15-20 min | 100% |
| Medium (onions, garlic) | 15-20 mg/m³ | 20-30 min | 100% |
| Strong (fish, meat) | 20-30 mg/m³ | 30-45 min | 95-100% |
| Very strong (chemicals) | 25-35 mg/m³ | 45-60 min | 90-95% |
| Stale (mold) | 30-40 mg/m³ | 60-90 min | 95-100% |
Fleet integration
After unloading
While driver processes paperwork and receives next assignment — vehicle is treated
Before loading
Preventive treatment before loading sensitive cargo: dairy, meat, vegetables
Night layover
Vehicles in the depot are treated at night — ready for run in the morning
Cargo change
When switching from one cargo type to another (fish → dairy) — mandatory treatment
Fleet economics
| Indicator | Ozonation | Chemical treatment |
|---|---|---|
| Equipment | 50-150 thousand ₽ (one-time) | Not required |
| Cost per vehicle | 30-50 ₽ (electricity) | 500-1500 ₽ (service/materials) |
| Staff | 1 operator | 3-5 washers |
| Time per vehicle | 30-40 min (unattended) | 60-90 min (manual work) |
| Odor elimination | Complete | Partial |
| Payback | 2-4 months | — |
When treating 50 vehicles twice a week, savings amount to 100-200 thousand rubles per month. Ozonator payback — 2-4 months. Additional benefit — reduced customer complaints about odors and contamination.
Compliance with sanitary norms
Road freight ozonation complies with requirements:
- SanPiN 2.3.4.050-96 — food product transport
- Technical Regulation TS 021/2011 — food product safety
- HACCP — critical control points in logistics
- ISO 22000 — food safety management systems
- Retail chain requirements for suppliers and carriers
Fleet equipment
For commercial transport treatment, the following are used:
- Mobile ozonators 5-20 g/h — for vans and medium trucks
- Portable ozonators 20-50 g/h — for semi-trailers and large transport
- Wall-mounted ozonators — for fixed installation in body
- 220V/230V modifications — for operation from electrical network without external power
- Timer systems — for automatic scheduled treatment
