We have a wide range of dry ice cooler boxes for sale
If you have ever camped, cooked, or slept outside, then you are familiar with the difficulty of keeping food chilled for an extended period of time outdoors. You will also know that having an ice cool box means you can do more of what you want when you go outside, and it makes you feel more in control of things. We offer a variety of dry ice cooler boxes for sale and are now proud to offer dry ice in Cape Town. You might also be interested in our range of polystyrene containers for sale.
But what exactly is a cooler box for dry ice?
Simply put, an ice cooler box is a portable device that helps you keep your food and drinks cool for an extended period of time. Only when something is actually needed from it does it get opened from its normally closed state.
Lighter-coloured ice cooler boxes reflect more sunlight, so they are the better option. When used properly, it can keep perishables in a near-frozen state from a few hours up to a couple of days. As the ice in your cooler slowly melts, you’ll need to empty it and refill it with fresh ice.
It takes a specific amount of heat energy to melt the ice. As ice absorbs this heat, its temperature stays nearly constant, but it begins to melt and transform into water. Because of the insulating properties of an ice box, external heat plays almost no role. It takes a great deal of time and thermal energy to melt a large block of ice. In spite of the fact that the ice cube may be melting, whatever you put in direct contact with it will remain cold.
Make sure to spend some money on a high-quality ice cooler box if you’re going to purchase one. Making a good decision requires knowing what it is that you are buying. If you frequently go out tracking, fishing, or camping, it is worth your time to look for quality cooler.
For decades, we have provided coolers and dry ice to teams and families heading on holidays. That’s why we can reliably determine what size cooler box and how much dry ice you’ll need for your trip, and how to appropriately load cooler boxes depending on the items inside.
A cooler that can be packed to capacity with as little extra room as possible is ideal for a journey. You don’t want your valuable ice to go to waste chilling air that isn’t directly in contact with your food or drinks. The size of the cooler is the most important factor. Many large retailers advocate keeping a 2-to-1 ratio of ice to food or drink, so we suggest that’s how much you should have in your cooler.
Keep your cooler in the coolest area you can find once you’ve cleaned it out after your last trip. You don’t want to pull it out of a closed car or a hot shed and immediately stuff it full of ice and tasty treats. The warmth from the cooler will seep into the cold stuff inside, wasting ice in the process. Keep it as cold as possible, and the summer heat will have to work its way through cold insulation before it reaches what’s inside.
Drinks should be stored in a different cooler from your food as you’ll probably want something to drink more frequently than you’ll want something to eat, so keeping the two in different places will prevent you from constantly opening the food cooler and letting warm air in. The liquids will still be drinkable even if the ice melts faster than expected but the food will spoil if it’s not kept chilled.
All ice is not the same, some are better than others. You can make your own ice or buy blocks, cube or dry ice from a supplier. Mixing dry ice with standard cubed ice is optimal since the cubed ice will quickly chill your contents and the dry ice will keep them cold for much longer.
The dry ice will cause anything it touches to freeze, so keep that in mind if you’re storing perishables. Separate the dry ice from your supplies with some newspaper or cardboard. If you expect to be constantly opening and closing the cooler, you should probably avoid storing dry ice at the top.
Putting things in your cooler in a haphazard manner and then putting ice on top is not only an inefficient way to keep them cool, but it also makes it harder to find what you need. Planning ahead can help you avoid this. It’s best to stack the ice and food so that the items you’ll need last are at the bottom.
