The Petromax cool boxes offer an impressive cooling capacity, which makes it possible to Keep ice at optimal temperatures for up to 12 days!

The particularly long cooling time results from a well thought-out design and high-quality materials. The double-walled construction of the Petromax cool boxes is made of resistant polyethylene, which provides excellent insulation. The decisive factor for the long cooling effect is the insulating property of the pressure-induced PU foam, which penetrates into even the smallest cavity of the double-walled body.

The insulating layer of this special PU foam has a low thermal conductivity and forms a powerful barrier against external heat. This design ensures that the internal temperature of the cool box remains constant and thus enables long-lasting freshness of the stored food and drinks. The Petromax cool boxes are designed to provide reliable cooling performance even under demanding conditions, be it high outside temperatures or changing environmental conditions.

The selection of the ideal cooler for you depends on your individual needs. If you value self-sufficient and energy-independent cooling, the Petromax passive cooling system is ideal. The Petromax cool boxes have already proven their stability and cooling duration in various product tests.

When choosing the right cool box, the size is crucial and should be selected according to your needs. We offer our cool boxes in the sizes 25l, 50l and 75l.

Adhesive pad:
The self-adhesive pad protects your cool box from scratches and knocks, provides more grip and is a perfect fit for the ultra-passive cooling system. The dense material forms a robust protective layer against moisture, UV radiation and the effects of temperature.

Seat cushion:
With the seat cushion, you can also turn your ultra-passive cooling system into a resting place to take with you. The cushion core made of permanently elastic foam forms the crucial basis. It ensures ideal pressure distribution under load and therefore a comfortable sitting experience.

Cutting and dividing board:
The Petromax cutting and dividing board not only functions as a cutting board, but also as a divider in the cool box, allowing food and drinks to be stored separately. The board has a drainage channel that collects leaking liquids and can be easily moved back and forth between the cool box and the work surface

Basket inserts:
The basket insert offers a gentle and cool storage option for sensitive food such as fresh vegetables and fruit. Perfectly matched to the inner edge of the cool box, it creates an additional temperature layer that ensures dry storage.
