What Are Cooling Systems Dry Ice Packs and How Do They Work?
La science de la sublimation: Ultra Cold Cooling Without the Mess
Dry ice packs are solid carbon dioxide that sublimate directly from solid to gas at about –78.5 °C (–109,3 ° F), creating extremely low temperatures without melting into liquid. Contrairement à la glace traditionnelle, they avoid water leakage and maintain stable, ultra cold environments for high value goods such as biologic medicines, glace, seafood and vaccines. When paired with insulated boxes or pallet blankets, dry ice absorbs heat while releasing carbon dioxide gas; this process maintains a consistent temperature over 48 à 72 hours depending on insulation and ambient conditions.
The absence of liquid residue keeps packaging and products dry—a critical advantage for electronics, confectionery and pharmaceuticals that are damaged by moisture. Dry ice packs are usually sealed in breathable materials with perforations to allow gas to escape, empêcher l'accumulation de pression. Because sublimation occurs evenly, you can adjust the amount of dry ice to match the required cooling duration; par exemple, high volume vaccine shipments may require larger packs or layering multiple dry ice sheets.
Beyond Freezing: Why Businesses Choose Dry Ice Cooling
When evaluating cooling systems, companies weigh cost, reliability and complexity. Dry ice packs are valued for their ability to deliver long duration, ultra cold temperatures without electricity or liquid runoff, making them ideal for remote shipments, emergency relief and cold chain logistics. They are particularly important for pharmaceuticals—biologic drugs now represent more than 50% of new approvals—which need temperatures below –20°C during transport. Frozen foods such as seafood and ice cream also rely on dry ice; the frozen food market is projected to exceed $450 milliards 2027 and seafood processing consumes about 18% of global dry ice output. Because dry ice doesn’t melt, products arrive without soggy packaging or quality loss.
Dry ice cooling also enhances logistics resilience. Temperature breaks cost the pharmaceutical industry an estimated $35 billion annually and spoil about 20% of temperature sensitive products. By using dry ice packs with insulated containers and real time monitoring, companies dramatically reduce the risk of temperature excursions. Some vaccine distributors have reported improved delivery efficiency by pre conditioning their containers and adding vented insulation layers around dry ice packs.
A Closer Look at Hybrid Cooling Systems
Many modern cold chains don’t rely exclusively on dry ice. Plutôt, they combine dry ice packs with phase change materials (PCMS), gel packs or mechanical refrigeration to create hybrid cooling systems. PCMs absorb or release heat at specific temperatures, while gel packs maintain 2–8 °C ranges ideal for chilled goods. Hybrid systems use dry ice for the initial freeze and PCMs for temperature maintenance; this reduces dry ice consumption and provides longer cooling durations. Par exemple, adding PCM panels above dry ice packs helps maintain stable temperatures during transit stops, reducing sublimation losses to 3–8% per day instead of 10%.
Hybrid systems also enable multi temperature loads. A container may have a frozen compartment cooled by dry ice for ice cream and a chilled section cooled by gel packs for salads. This versatility reduces packaging waste and improves shipment efficiency, particularly for last mile delivery services that handle mixed products. Hybrid solutions are trending because they balance cost, sustainability and performance—a theme explored later in this article.

| Packs de gel | 0°C à 8°C; maintains chilled temperatures | Moderate cost; reusable and less carbon intensive | Modéré; easy handling but can leak water | Suitable for fresh produce, dairy and short distance deliveries |
| Water packs | Around 0°C; freezer bricks or ice bags | Faible coût; minimal ecological impact | Simple; widely available and reusable | Good for picnics, beverages and short events; not ideal for long distance shipping |
| Matériaux à changement de phase (PCMS) | Customisable (Par exemple, –20°C, 4°C, 15°C) | Coût plus élevé; can be eco friendly | Moderate complexity; must be charged/frozen in advance | Offers stable, long lasting temperature control and reduces reliance on dry ice |
| Mechanical refrigeration | Réglable; can reach ultra low temperatures | High capital cost but zero consumable waste | Complex; requires power, maintenance and compliance | Used in reefer trucks, cold storage rooms and containerized freezers |
Practical Tips for Choosing Cooling Systems Dry Ice Packs
Pre condition containers: Chill your insulated box or cooler to the target temperature before adding products. Pre chilling reduces initial heat load and slows sublimation.
Superposer stratégiquement: Place dry ice packs on top of goods because cold air sinks, and fill empty spaces with foam or bubble wrap to minimise air pockets.
Combine refrigerants: Pour les charges mixtes, use dry ice for frozen items and gel or PCM packs for chilled sections. This hybrid setup offers multi temperature control.
Choose the right size: Estimate 5–10 pounds of dry ice per 24 hours for frozen shipments; adjust according to load weight and ambient temperature. For smaller parties or short trips, 2–3 pounds may suffice.
Utiliser un emballage ventilé: Always select insulated containers with venting to allow CO₂ gas to escape. This prevents pressure build up and protects products.
Exemple du monde réel: A vaccine distributor transporting shipments across remote regions used insulated containers with vented lids and layered dry ice packs above the payload. By pre cooling the containers and combining dry ice with PCM panels, they achieved 48 hour temperature stability and reduced dry ice consumption by 30%. This approach also simplified handling because staff only replaced PCM panels during refueling stops, avoiding the need to open containers and risk contamination.
How to Handle and Dispose of Cooling Systems Dry Ice Packs Safely?
Essential Safety Precautions: Protecting Yourself and Others
Working with dry ice requires respect for its extreme cold and gaseous state. Direct contact can cause severe cold burns, and enclosed spaces may accumulate carbon dioxide gas that displaces oxygen. To use cooling systems dry ice packs safely:
Portez un équipement de protection: Use insulated gloves and eye protection when handling dry ice. Évitez de le toucher avec une peau nue, as even brief contact can freeze tissue.
Travailler dans des zones aérées: Always handle dry ice in a well ventilated room or outdoors. If indoors, open windows and use fans to disperse CO₂ gas.
Use vented containers: Store and transport dry ice in insulated, vented containers with loose lids or small holes; never seal dry ice in airtight coolers or glass jars because the gas expansion can cause explosions.
Avoid ingestion: Never place dry ice directly into drinks or food intended for consumption. Swallowing dry ice can cause internal burns and asphyxiation.
Supervise children and pets: Keep dry ice away from curious hands. Use caution when using dry ice for fog effects at parties; supervise the area to prevent accidental contact..
Safe Storage and Transportation Guidelines
Transporting dry ice in vehicles or aircraft requires planning. Only a limited amount (généralement 2.5 kg per package on air shipments) is allowed, and packages must be labelled as “Dry Ice” to comply with regulations. For road transport, avoid placing dry ice in the trunk of a car; instead, keep windows open to allow gas to escape.
Lors du stockage de blocs de glace carbonique:
Insulation and venting: Use double walled boxes or foam coolers with vented lids. Never tape or seal the container entirely, as CO₂ build up could rupture the packaging.
Label and separate: Mark containers clearly with “Dry Ice – CO₂ gas” warnings, and separate dry ice from flammable materials or products that may be damaged by extreme cold.
Plan deliveries: Because dry ice sublimates at 3–8% per day even with good insulation, coordinate shipping schedules to minimise transit time and have contingency plans for delays. Real time temperature monitoring devices can send alerts if temperatures deviate from safe ranges.
Élimination: Let It Sublimate
The safest way to dispose of dry ice is to allow it to sublimate in a well ventilated area. Place remaining dry ice in an open container outdoors or in a vented room and keep away from children and pets. Do not pour dry ice down drains or throw it in trash chutes—if trapped in a confined space, sublimating CO₂ can cause pipes or trash bins to explode.
Practical Scenario: After a successful delivery, a food service manager disposed of unused dry ice by leaving it in a designated open container in the loading bay. The dry ice slowly sublimated within a day. The manager ensured signage warned staff about the hazard and kept the area ventilated to avoid CO₂ accumulation. This simple practice prevented a waste chute explosion that might have occurred if the dry ice had been discarded with general waste.
Cooling Systems Dry Ice Packs vs Gel Packs and Other Alternatives
Why Comparison Matters
Different cooling technologies serve different purposes. Understanding their strengths and limitations helps you choose the right solution for each shipment or event. Dry ice packs deliver ultra low temperatures but come with higher costs and more complex handling, while gel or water packs provide moderate cooling with fewer safety precautions. Phase change materials offer custom temperature control and longer duration; mechanical refrigeration eliminates consumable use but requires power and maintenance.
