Reusable cold accumulator COLDPACK 225 ml (gel, up to 90 kJ, for thermal bags, refrigerators and transportation of medicines +2…+8 °C)

COLDPACK 225 ml cold accumulator — a reusable gel element in a durable food-grade polyethylene bottle. Put it in the freezer in the evening — and in the morning you have up to 90 kJ of “preserved cold”: a thermal bag on a picnic or fishing trip, a container with medicines on the road or a refrigerator left without power, maintains temperature for hours.

Size: 160 x 63 x 35 mm

How it works

Filler — demineralized water with thickener E 415 (xanthan gum) and preservative. The gel completely freezes at −18 °C, and during thawing it maintains a temperature around 0 °C for a long time — this “plateau” is what cools the contents of the bag or refrigerator. Energy capacity is calculated at up to 90 kJ (up to 25 W·h), of which up to 75 kJ comes from the heat of ice melting; roughly this is enough to cool about a liter of drinks from room temperature to +8 °C. Unlike water-filled accumulators, COLDPACK does not require filling with water — take it out of the box, freeze it, and use it.

Advantages

• freezes completely — maximum cold reserve from 225 ml volume;
• reusable: “freeze – use – freeze” cycle without loss of properties, shelf life 5 years;
• gel filler maintains ≈0 °C during thawing and does not leak into a puddle if damaged;
• charges in a regular household freezer for 10–12 hours;
• bottle format fits between products, in a thermal bag pocket and on refrigerator door shelf;
• suitable for cold chain +2…+8 °C according to protocol on label;
• HDPE body withstands storage from −25 to +35 °C, can be kept permanently in freezer;
• manufactured in Ukraine (LLC “IMEX MAX”, TU U 22.29-42831345-044:2020).

How to use

1. Place the battery in the freezer (−18 °C) for at least 10–12 hours — until the contents are completely frozen.
2. Place in a thermal bag or container next to products or in a refrigerator when power is off.
3. After use, refreeze the product — it is ready for the next cycle.

Transportation of temperature-sensitive medications (+2…+8 °C)

Before packing, keep the frozen accumulator at room temperature for 20–40 minutes — until moisture appears on the surface. Do not place it directly against medications: use a layer of corrugated cardboard or packaging film 5–10 mm thick (medications in the center, accumulators around the perimeter and on top) and monitor the temperature with a thermometer. Maintaining the temperature regime depends on the quality of thermal packaging and adherence to the usage method.

Cold reserve during blackout

When the power goes out, move the frozen accumulators from the freezer to the refrigerator shelves — they will absorb heat and extend product preservation. The more accumulators frozen “in reserve,” the longer the refrigerator will last without electricity.

Safety

Do not open or damage the case, do not ingest the contents, do not apply to the body. The product is not medical. In case of damage and leakage of filler — dispose of it, avoid contact with eyes and mucous membranes. Do not heat and do not use in a microwave. Keep out of reach of children.

Who needs it

Families — for picnics, dacha and shopping in hot weather; fishermen and hunters — to deliver catch; volunteers, pharmacies and medical professionals — cold chain for medications; everyone — as a cold reserve for the refrigerator during power outages.
