Cold Room & Cold Storage Treatment
Cold-storage treatment must protect both stored goods and people. Ozone may be evaluated for a controlled, unoccupied treatment cycle only where commodity compatibility and a verified return-to-service procedure are established.
Discuss Your ApplicationThe Treatment Challenge
Odours and microbial contamination can persist on surfaces, packaging and inaccessible areas. Low temperatures, humidity and uneven air circulation affect treatment distribution, while sensitive commodities may be damaged by oxidation.
How Ozone Helps
Ozone can oxidise selected compounds and may affect exposed microorganisms under validated conditions. It is not a substitute for cleaning or temperature control, and effectiveness against a surface or commodity cannot be assumed from room-air readings.
Process engineering
Technical Treatment Approach
An assessed oxygen supply and generator feed a controlled circulation arrangement in an isolated room. Distribution, contact duration and sampling locations are selected for the actual storage geometry. Residual ozone is removed or ventilated safely and measured before re-entry or restocking.
Key Benefits
- May support a validated between-cycle treatment step
- Can be assessed for selected persistent storage odours
- Encourages monitored clearance before room reuse
System Integration
Refrigeration, humidity control, cleaning and stock management remain primary controls. Ventilation or ozone destruction must be compatible with the room’s services, and packaging or food-contact conditions need a separate compatibility assessment.
Engineering & Automation
PLC-controlled treatment and clearance sequences may use HMI status, door interlocks and ozone sensors. Alarms and emergency shutdown should prevent access during treatment; remote initiation must not bypass occupancy checks or local authorisation.
Available depending on system configuration and project requirements.
Important Design Considerations
Actual air quality, circulation flow, contaminant load and storage objectives determine dose, contact time, distribution efficiency and performance. Validate commodity and material compatibility, condensation effects, by-products and safe clearance; do not use a fixed elapsed time as proof of re-entry safety.
