Surgélation cryogénique

Our cryogenic freezing solution for food products brings you:


Safeguard the freshness, texture and flavour of products

Thanks to a very rapid drop in temperature at the core, cryogenic freezing ensures micro crystallization of water in the cells, preserving there integrity and the texture of food products.


Flexibility and productivity gains

Cryogenic equipment can adapt to any change in production, by adjusting the flow rate and the set temperature of the fluid. In addition, since water losses linked to dehydration are limited, your product yield is optimised.


Space saving and ease of integration

At power equivalent to conventional mechanical cold, cryogenic equipment is less bulky and can be adapted to many configurations. Simple in design, they are quickly operational and fit naturally into the existing production line.


Optimised utilisation rate

Cryogenic equipment is mechanically very simple, without a compressor, which implies less maintenance, less defrosting. Easy and fast cleaning is due to the better accessibility. This reduces downtime.

Our cryogenic freezing solution for food products optimses the performance of your products

With Air Liquide, benefit from complete cryogenic freezing solutions adapted to your
manufacturing process, combining gas, equipment and technical expertise.


Approvisionnement d'Air Liquide

Cryogenic cold Vs mechanical cold

If mechanical refrigeration is a very widespread technology, cryogenic refrigeration offers many advantages, sometimes unrecognized, in terms of product quality, freezing speed, flexibility of installations. Air Liquide explains the advantages of cryogenic cold and the difference with mechanical cold.
