The Junior Sous can maintain temperatures for up to 4 hours plus. The exact time however, will depend on how much food you put in the box. Larger cuts of meat and more dense food - picture large pieces of slow-cooked roasts, curries, bakes, lasagnes - will keep very hot for 3-4 hours. The more space in the box, the quicker the temperature will drop - however even for smaller meals, expect it to hold nicely for an hour or two. If wanting to maintain food at a cold temperature, with the use some ice bricks, the food will stay fresh for 2-4 hours. Again, this depends on the amount of food and how full the box is - salads, cheese and cold cuts, fruit, desserts will stay fresh for hours.

Unlike traditional coolers that open at the top, the Junior Sous is purpose-built for food and offers front-loading access, integrated rails to keep trays and platters secure and professional-grade all-round insulation designed specifically for temperature control, not just ice. The modular, nesting design also allows for securely stacking multiple boxes on top, and also offers an instant prep or serving station on top.

There is no electricity required. Our boxes are fully insulated so once hot food goes in the insulation will help retain the heat. The portion size of your food will play a factor into how long it will stay hot for. You can also pre-heat the box to further support the temperature control.

While not required, particularly for large and dense serves of food, pre-heating or pre-chilling the Junior Sous for 15 minutes before loading food will support the temperature retention, especially for longer transports.

Internally, the Junior Sous is 27cm wide and 34 cm deep, with three sets of rails. While our stainless steel trays fit perfectly, we have designed the internal space to be very versatile. And here’s a tip - our flat trays can also act as a shelf for smaller trays, platters or plates that don’t fit on the rails.
