2kg Gel Brick
These hard gel packs are designed for serious outdoors people. The larger volume of each ice pack will give a longer lasting cooling effect than using multiple small packs.
Coupled with the large flat design, it will cool the contents of your ice box very quickly and will not make the contents wet and having water slosh around in the bottom of your cooler, keeping the contents dry.
Our PCM (Phase Change Material) formulation contains non toxic agents added to make the thawing time longer than regular water. These gel packs will freeze in your household freezer in 12 hours, although 24 hours or more is best for longer lasting results.
Made from strong polyethylene outer casing that will withstand most of the abuse thrown at it from regular use in your cooler. It is also food safe and will not taint your food or drinks.
The 2 sizes are
2kg (2000 ml capacity) - is 31cm x 28cm x 3 cm (weight 2.1kg)
3.5kg (3500 ml capacity) is 26cm x 40cm x 4cm (Weight 3.6kg)
We recommend using at least 1kg of these hard gel packs per 10 litres of cooler volume for 1 to 2 days. For longer trips, you would double the Gel Packs or add the same weight of ice.
So 1 x 2kg Gel Pack would be the minimum for a 25L cooler.
For a 90 litre cooler, You would want 5 x 2kg Gel Packs or 3 x 3.5kg Gel Packs.
Best results are obtained if the food and drinks are already cold before adding to the cooler.
