Iseco – Guaranteed Temperature Control in Cold Food Distribution

With a big shift occuring towards central production kitchens for distribution to satellite locations, the guarantee of delivering product within HACCP guidelines has always been an issue. The amount of critical controls points involved up until the meal is delivered to your guest or resident is numerous. Examples such as distribution of product via the loading dock, refrigerated transport, safely decanting at destination to shuttling to finishing kitchen for service are all steps that can cause issues in the supply chain.

Here’s the ‘Game Changer’ – CO2 chilled trolleys for HACCP compliant autonomy in meal distribution for at least half a day!

Introducing Iseco Carbo Fresh

What is Carbo-Fresh?

ISECO the renowned manufacturer of meal distribution trolleys from France in collaboration with Air Liquide (a global player in the production of industrial gas) has developed and adapted a very impressive system of refrigerating trolleys. The trolley is equipped internally with a special cassette that utilises liquified Carbon Dioxide(CO2). The cassette is injected with CO2 which instantly reduces the internal temperature of the trolley to 3 ̊C while at the same time filling the cassette with dry-ice.

The trolley loaded with chilled food is kept refrigerated by the CO2 (snow) which gradually sublimates and absorbs heat creating the required chill effect, whatever the ambient air-temperature. When no heat is absorbed (because the food is loaded at the correct cold temperature) there is hardly any sublimation of CO2. Ambient air temperature, duration time of transportation, and the actual contents of the trolley all combine to determine the volume of CO2 required to be injected. Therefore, there are no moving parts or refrigerants utilised

How would it work for your site?

The beauty of the system is that Air Liquide provides a scalable infrastructure solution for every site. From small, portable solutions to large scale production sites. The cost is amortised through the supply of CO2 to site so the outlay is minimised.

The trolleys are filled using an injection system (provided by Air Liquide) which controls dosage, extracts excess CO2 & monitors / alerts for any issues.

Example of Use



Does Carbo-Fresh add to global warming? In fact, all methods of cold production add to global warming. The CO2 that is used in this system is a cleaned, purified and recycled bi-product of the chemical industry (collected during the production of industrial grade ammonia), adding very little to global warming. Although appearing to be contradictory, it is a very sustainable system. Even when all the effects of CO2 transportation and supply are taken into account, surveys show a huge decrease of emissions compared with any conventional refrigeration technology.

When you take into consideration the entire distribution cycle such as cold room storage, refrigerated transport and destination refrigerators. Iseco Carbo Fresh will ensure a huge reduction on the Carbo footprint of the operation.

What are the benefits?

  • No on-board technology meaning there is no maintenance required. This compares to maintenance of cold rooms, refrigerated transports etc

  • HACCP temperature compliance is adhered to. The nature of CO2 ensures temperature is maintained, no matter the ambient temperature. There is no risk of breakdown and the system allows for a contingiency if there are any transport issues.

  • Daily running costs and whole-of-life costs are reduced using the Iseco system
