Understanding Load Shedding and Freezer Challenges in Pakistan
Load shedding is a persistent challenge in Pakistan, particularly in Karachi, where scheduled and unscheduled power outages can last for hours. These interruptions put your frozen food at risk, as freezers begin to lose their cold temperature soon after the power goes out. Without a backup plan, food spoilage and waste become real concerns for households and businesses alike.
Why Freezers Warm Up Quickly During Outages
Modern freezers are well-insulated, but they are not designed to maintain subzero temperatures indefinitely without power. During load shedding, the internal temperature can rise rapidly, especially if the freezer is opened frequently or is not fully packed. This can lead to:
- Thawing of frozen food
- Loss of food quality and safety
- Increased risk of spoilage and waste
How Dry Ice Provides Freezer Backup During Load Shedding
Dry ice, the solid form of carbon dioxide (CO₂), is extremely cold at -78.5°C. When placed inside a freezer, it absorbs heat and helps maintain low temperatures, even when there is no electricity. Dry Ice Pakistan supplies dry ice pellets in sizes suitable for both home and business freezer backup needs.
Key Benefits of Using Dry Ice for Freezer Backup
- Immediate cooling: Dry ice starts working as soon as it is placed in the freezer.
- No need for electricity: It keeps your freezer cold during even the longest outages.
- Flexible pack sizes: Dry Ice Pakistan offers retail packs of 2kg, 5kg, 10kg, 15kg, and 20kg to suit different freezer sizes and outage durations.
Practical Karachi-Focused Guidance for Using Dry Ice
1. Choose the Right Pellet Size
Dry Ice Pakistan’s retail default is 16mm pellets, which are ideal for freezer use. These pellets are easy to handle and distribute evenly throughout the freezer compartment.
2. Estimate the Quantity You Need
The amount of dry ice required depends on your freezer’s size and the expected duration of the power outage. As a general guideline:
- Small home freezers (up to 100 liters): Start with a 2kg or 5kg pack.
- Medium to large freezers (100–300 liters): Consider 10kg or 15kg packs.
- Commercial or large storage freezers: 20kg or more may be appropriate.
If you are unsure, contact Dry Ice Pakistan for guidance or use a dry ice calculator to estimate your needs.
3. Safe Placement of Dry Ice in Your Freezer
- Use insulated packaging: Place the dry ice pellets inside insulated packaging or wrap them in newspaper to slow sublimation and protect freezer surfaces.
- Distribute evenly: Arrange the dry ice on the top shelf or throughout the freezer for even cooling. Cold air sinks, so placing dry ice above the food helps maintain uniform temperature.
- Limit freezer opening: Keep the freezer closed as much as possible to retain cold air and maximize the effectiveness of the dry ice.
4. Ensure Proper Ventilation
As dry ice sublimates, it releases carbon dioxide gas. Always use dry ice in a well-ventilated area. Avoid placing your face directly inside the freezer when adding or removing dry ice.
Essential Safety Guidelines for Handling Dry Ice
Dry ice is safe when handled correctly, but improper use can be hazardous. Follow these safety tips:
- Wear insulated gloves: Always use insulated gloves when handling dry ice to prevent frostbite and skin burns.
- Avoid direct skin contact: Never touch dry ice with bare hands.
- Do not store in airtight containers: As dry ice sublimates, it releases gas that can cause airtight containers to burst.
- Keep away from children and pets: Dry ice is not a toy and should be handled only by responsible adults.
- Use ventilated packaging: Transport and store dry ice in containers that allow gas to escape.
- Do not ingest: Dry ice is not edible and should never be consumed.

- Group frozen items: Keep items close together to reduce air gaps and slow warming.
- Monitor freezer temperature: Use a thermometer to track internal temperatures and ensure food safety.
- Plan for extended outages: If load shedding is expected to last several hours, consider using larger dry ice packs or supplementing with additional ice.
