The STABILUS ice block Petromax 140 BLUE is a reusable cooling pack designed for passive temperature control in coolers, lunch boxes and during short-term transport. Shaped as a flat block, this frozen pack is intended to be placed inside insulated containers to help maintain low temperatures for food, beverages and other temperature-sensitive items. The product is suitable for repeated freezing and simple handling, offering a practical cooling solution without electronics or active power.
Advantages
This reusable cooling pack provides reliable passive cooling performance when frozen and placed alongside goods in insulated carriers. It is durable for multiple freeze-thaw cycles and eliminates the need for single-use ice. The flat block shape maximizes contact area with surrounding items, improving thermal transfer in small to medium containers. The product is simple to use and store, and it does not emit odors or liquids when properly maintained.
Suitable for
- Coolers and picnic boxes for food and drinks
- Lunch boxes and meal delivery containers
- Short-term transport of perishable goods and temperature-sensitive items
- Insulated storage during outdoor activities and trips
Key specifications
- Type: reusable frozen cooling pack in block form
- Shape: flat rectangular block suitable for stacking and close contact
- Material: robust outer shell with non-toxic internal coolant
- Intended use: passive cooling inside insulated containers

How to use
Place the cooling pack in a household freezer until fully frozen according to your freezer's recommended freezing times. Once frozen, position the ice block inside a cooler, lunch box or insulated transport container in direct contact with items to be cooled, ensuring even distribution for optimal temperature control. After use, allow the pack to thaw if necessary, then clean the outer surface with a damp cloth and mild detergent before refreezing or storing. Avoid puncturing the shell and keep the pack away from sharp objects.
Usage recommendations
For best results combine one or more frozen STABILUS ice blocks with insulated containers and minimal air gaps around items. Pre-chill contents when possible, keep coolers closed during transport, and replace or refreeze packs between trips. Do not expose the pack to open flames or high heat, and inspect the outer shell regularly for damage before each use.
