5 Tier Flexeserve Food Warmer Display

Hot Food to Go

With consumers eating out more often, the hot food-to-go sector is proving highly lucrative for operators.

Self-service food is a fast, convenient and affordable solution for a generation on the go. A new age of foodservice and convenience retail is upon us, with demand for innovative products that not only look and taste delicious and are fresh when cooked, but retain optimum quality for hours on display.

Unique technology

Nuttall’s patented, award winning technology is the result of over 25 years’ research and development within the heated display industry.

Unique air recirculation technology

Flexeserve Zone® uses convection technology rather than relying on outdated contact heat. Hot air is continually circulated throughout the entire volume of each zone and creates a consistent and stable environment for your products.

This even distribution of air within each zone means food does not continue to cook, unlike in heated units that use conduction that acts like a hot plate. In Flexeserve Zone,® food is held at the appropriate temperature and product integrity is maintained – no hard bottoms, no soggy tops.

Air curtains

The tight air curtains within Flexeserve Zone® retain the hot air within the unit. As well as making the unit extremely energy efficient, it also means that Flexeserve Zone® is tolerant to lower environmental store temperatures and does not allow heat to escape, which impacts store conditions.


Each zone is individually controlled by a user- friendly control panel to create the perfect temperature for the range of products you are serving. Zones can have their own set temperature and you can also switch them off independently to suit different trading patterns throughout the day, saving energy.


There is an insulated thermal barrier between each zone to prevent heat transfer from the zone above or below. The zones are also in direct contact with the double glazed end panels, further inhibiting the movement of hot air between zones. The
end panels also prevent heat escaping through the sides of the unit, as well as ensuring external surfaces are safe to touch.

Easy to clean and maintain

Flexeserve Zone® provides flat, easy-to-
clean surfaces all round, as well as a range of merchandising accessories that are dishwasher safe. The unit can be simply wiped with a damp cloth and cleaned with a food safe sanitiser.

Maintenance of Flexeserve Zone® couldn’t be simpler. The modular ‘plug-and-play’ design of the technology within each unit allows you to quickly and easily replace components with minimum disruption to service. As each zone has its own individual controller, if one was out of operation, the remaining zones work as normal allowing trade to continue.

Environmental responsibility

We are committed to being ahead of the industry throughout our business and there is no exception with the environment. By considering a variety of factors, we work to reduce the carbon footprint of our products:

  • Energy saving features.
  • Reduced thermal impact on store environment.
  • Reduced food waste.
  • Reduced single-use plastic packaging.
  • Promoting and co-developing recyclable and compostable food packaging.

Your food … fresh.

How do you hold the perfect toastie? Keep a croissant crisp? Muffins and brioche soft and springy? Poached eggs runny? Soup and gravy that won’t develop a skin?

Products with multiple components, such as curry and rice, or creamy mac and cheese, will hold true and consistent.

And then the ultimate – French fries and pizza stay fresh and crisp for longer.

The capabilities of Flexeserve Zone® are unrivalled.

Each product has its own optimum conditions for maintaining both food quality and temperature. By developing a truly unique and patented flexible hot-holding solution we have greatly improved the world of hot food-to-go.
The technology we have developed in Flexeserve Zone® enables® you to hot-hold a wider variety of food that will keep your customers returning. You can serve products across all day parts using multiple temperature regimes in different zones.

The science of true hot-holding is not just about temperature alone, it is actually as important to retain moisture within products to keep them stable. Flexeserve Zone® is capable of doing this whilst also retaining the perfect texture, flavour and product integrity.

What Our Clients Say

“The FlashGrill is so good. Always such an even cook. Never have to worry about re-heating, it’s always at temp. Super easy to clean and nothing ever sticks. We cover the plate with 30 frozen burgers, cook them, then add another 30 straight away with no change in cooking time between the first lot and the second and get the same great result. It’s really impressive” Katrina Sanderson, Food Operations Manager - Bowser Bean and Vantage Fuels

It enhances flavours by cooking at low temperatures.

"FlashGRILL completes any food. It enhances flavours by cooking at low temperatures. It can perfectly caramelise and grill the products. It is great for white meat and fish. It is very satisfying to cook different kinds of meats and ensuring clients can fully perceive the differences in tastes due to the specific flavour of each product being preserved."Chef Francesco di Maria, - LA FIORENTINA Ristorante-Pasticceria Roma - Italy
“Since I have had the possibility to cook at lower temperatures, meat does not stiffen or burn. It remains evenly cooked and intact, and enhances flavour. Thanks to FlashGRILL, which keeps the temperature even on the full cooking surface, I managed to optimise cooking in my work kitchen. I also use the CLOCHE every day. Thanks to it, I obtain great results with meat and fish, like tuna. I am extremely satisfied.”Chef Diego Asara, - GINGER SAPORI E SALUTE Roma - RM
