Cooling Keep your food cool with a cool box, rucksack and bag.

The Petromax cooling products are designed to keep your food and drinks cool for a long period of time without electricity. The Petromax cool boxes can keep your supplies fresh for up to 12 days by using an ultra-passive cooling system powered by ice or ice packs. The cooler bags offer up to 6 days of cooling, while the cooler backpacks can keep your food and drinks cool for up to 8 days. These periods can vary depending on the outside temperature and usage, but they offer you the security of always having fresh food available, even on long trips.

The cool boxes, cool backpacks and cool bags use an ultra-passive cooling system that works completely without electricity. This system uses commercially available ice or ice packs to keep the temperature in the box, bag or rucksack low. As no compressor or absorber is required, the cooling products are particularly robust and reliable. This method is not only energy-efficient, but also very easy to use and ideal for anyone who wants to be independent of power sources when traveling.

Cleaning your Petromax cooling products is easy and uncomplicated. Our cool boxes are equipped with an integrated drainage system that facilitates the removal of melt water and cleaning. You can simply rinse out the box and drain the water via the drainage system. For the cooler bags and cooler rucksacks, it is sufficient to wipe them with a damp cloth and then allow them to dry thoroughly. Make sure to clean the products regularly to keep them in top condition and prolong their lifespan.

Choosing the right size depends on your individual needs and the intended use. If you are on long expeditions or camping trips and want to take larger quantities of food and drinks with you, Petromax cool boxes are ideal. They offer plenty of space and a long cooling capacity. The cooler bags are perfect for shorter trips or day trips as they are more compact and easier to transport. If you travel a lot and need maximum mobility, the cooler backpacks are the best choice. They allow you to carry your supplies comfortably on your back while keeping them cool for a long time.

The Petromax cooler bags and cooler backpacks are made of water-repellent material and have waterproof zippers. This ensures that your contents are optimally protected, even if you are traveling in damp or wet environments. The cool boxes are also robust and offer a high level of protection against moisture. These features make our cooling products reliable companions in all weather conditions and outdoor activities.
