For decades, preparing food ahead of service has typically meant moving through a familiar cycle: cook it, cool it, refrigerate it, reheat it and finally serve it.
But what if some of those steps weren’t necessary?
EVEREO® is built around a fundamentally different idea: keep fully cooked food hot, preserved and ready to serve until it’s needed.
Known as the world’s first hot fridge, EVEREO is a service-temperature food preserver designed to hold fully cooked meals at the temperature at which they will be served for up to 72 hours. Using UNOX’s patented Service Temperature Food Preserving technology, food can remain ready for service without moving through the traditional cooling and reheating cycle.
For operators, that changes more than food holding. It creates an opportunity to rethink when and where production happens.
Cook Ahead. Serve When Demand Happens.
In a traditional kitchen, production is often closely tied to anticipated demand. Prepare too little, and the team has to react quickly during service. Prepare too much, and operators risk unnecessary waste.
EVEREO introduces another option.
Fully cooked food can be prepared ahead and preserved at service temperature, allowing kitchens to shift more production into periods when labor and equipment capacity are available. When demand arrives, food is already prepared and ready for service.
For shorter holding periods, EVEREO’s SUPERHOLDING function allows food in open containers or unsealed trays to remain at service temperature for up to eight hours. For longer preservation, the MULTI.Day system combines EVEREO with hot vacuum sealing, allowing food to be preserved for up to 72 hours. A fully loaded tray can be vacuumed and sealed in less than 75 seconds.
The result is greater control over the relationship between production and service.
A Different Workflow, Backed by Research
Changing an established foodservice process requires more than convenience. Operators need confidence in what happens to the food while it is being preserved.
Research into EVEREO’s hot-preservation process has examined both microbiological safety and nutritional quality.
In one comparative nutritional study, beef meatballs and chicken curry were preserved in EVEREO at 63°C and compared with identical products refrigerated at 4°C for approximately 24 hours. Researchers evaluated 25 nutrients across vitamins, minerals and antioxidants. For the vast majority of nutrients tested, there were no statistically significant differences between the two preservation methods.
Additional research has evaluated the microbiological safety of different foods cooked and hot held at 62°C or 70°C, providing another layer of evidence behind the preservation method.
That research matters because EVEREO isn’t simply about keeping food warm. It is about creating a controlled preservation process that allows operators to approach production differently.
More Flexibility Beyond the Traditional Kitchen
That flexibility can extend beyond the back of house.
EVEREO is available in three configurations: the compact EVEREO CUBE for tight or non-kitchen spaces, EVEREO 600 for counter or bar installations, and the stackable EVEREO 900 for higher-volume operations.
Food can be produced centrally, preserved and then served from satellite locations such as hotel outlets, ghost kitchens or other venues without a traditional production kitchen onsite.
For hotels, catering operations, restaurants and high-volume foodservice, that opens a larger conversation about labor, production space, menu availability and where foodservice can happen.
The question is no longer simply how quickly a kitchen can respond when an order arrives.
It’s whether the kitchen needs to wait for the order to begin with.
EVEREO® gives operators another option: cook ahead, preserve at service temperature and serve when the customer is ready.
