Best Dry Ice Cooler Boxes for Sale

 It was an American named Richard Laramy who, in 1951, is credited with creating the first modern cooler box. It was given the Danish name of Kampkold, which literally translates as “fighting cold.” The cooler box became popular as a home item in warmer sections of the US during summer, when refrigeration and ice for cooling foods and drinks first caught on. We offer a wide range of high-quality cooler boxes for sale. You might also be interested in dry ice in Cape Town and our variety of polystyrene containers for dry ice.

 Coleman, a firm with almost a century of experience in the outdoor industry, bought the rights to the cooler in 1954. They eventually switched to plastic instead of metal and renamed the ice chest the “cooler”. In addition to their traditional use in the home, cooler boxes are now commonly seen at outdoor events such as picnics, camping trips, beach outings, road trips, school sports events, and even ice cream stands.

For the purpose of providing insulation, coolers are typically constructed by placing two layers of plastic, metal, or fibreglass in between two layers of rigid foam, or by injecting expanding polyurethane foam into the hard foam. In comparison to its soft-shell equivalents, hard-shell cooler boxes, in general, offer superior cooling performance. Although fibreglass was once widely used, plastic rotomoulded coolers have mainly displaced it due to their lower production costs and greater ease of use.

The method of rotomoulding involves placing plastic pellets inside of a heated, hollow metal mould that is then rotated across two axes that are perpendicular to one another. In the case of coolers, the procedure enables a completely even and thick layer of plastic to be applied to the mould, which increases the coolers’ ability to retain heat. Because of the high cost of the moulds and other variables, this technique, which is still considered to be a somewhat expensive process, is only used for the highest-end coolers. 

Choosing a cool box can be challenging due to the wide variety of options available, from inexpensive models to rugged outdoor recreation models. A proper understanding of the distinction between all models will prevent you from wasting money on an inappropriate cooler and the subsequent disappointment that comes from that purchase.

The type of cool box you’ll require is heavily determined on the intended use. You will also have to think about how much things has to fit in the cooler, how much electricity is available and how much you want to spend. The sheer size of a cooler is the first thing that stands out. Larger coolers can be impractical and add extra weight to your pack on particular excursions, despite the fact that you may not see the harm in making sure there’s capacity to spare. An oversize cooler will not store as much ice as a smaller one, especially if you don’t fill it to capacity with ice plus whatever you’re trying to keep cold. If you want to keep your ice and cooler contents cold for as long as possible, it’s best to get the smallest cooler that will hold everything you need.

Instead of filling your cooler with melted ice and finding your food soggy, use dry ice. Dry ice won’t melt, so it won’t water down your drinks or spoil your food. To avoid explosive buildup, select a gas-permeable cooler and stock up on dry ice. Determine if you’ll be using the cooler like a freezer by placing the dry ice on the bottom and the food and drinks on top, or if you’ll be using the cooler as a traditional cooler. Place your fish, meat, or game on the bottom of the cooler and set your dry ice on top to quickly freeze your food. Wear protective gloves at all times when working with dry ice.

Take care to shield the plastic lining of your cooler from the dry ice’s extreme cold if you’re not using a styrofoam one. You can line the bottom of the cooler with cut pieces of styrofoam or cardboard. There may be a buildup of gas in the cooler as the dry ice evaporates. If you are using styrofoam or the urethane box, leave the lid cracked slightly to prevent any damage. Remove the drainage cap from your cooler by unscrewing it slightly if it is made of plastic or rotomolding. The plastic in the cooler could crack if the gas was trapped inside without a vent.

Dry ice is typically sold in large blocks or chunks. Unlike dry ice pellets, these won’t melt as quickly. You should measure your cooler before going out to buy dry ice so you know how many blocks to get.

Depending on the conditions, dry ice can evaporate on its own over the course of several hours or days. Dry ice in a cooler should be discarded by leaving the cooler lid open or off and taking it outside. If you wrapped your dry ice in newspaper, take off the wrapping. To get rid of dry ice, just put it outside. If there are young children or pets in the house, they should be kept away from the dry ice, and the dry ice should never be left unattended.
