Freezing & Chilling

Our solutions for cryogenic food applications

With more than 100 years of experience as a partner to the food industry, Air Liquide has a portfolio of gases and systems that covers all stages of food production, from storing raw materials to transporting the ready-to-sell product.

Freezing and Chilling at a glance

In the food industry, freezing usually refers to deep freezing, or lowering the temperature of a product below -18°C. In contrast, chilling refers to the rapid cooling of a food product from its manufacturing temperature down to refrigerated or cold temperatures, usually from 2 to 4°C. 

Compared to traditional mechanical freezing and chilling technologies, cryogenic food refrigeration offers advantages in terms of product quality which is critical for added-value, complex or fragile products, and also in terms of improved productivity, greater process flexibility especially for small to medium production outputs, reduced capex requirements and optimizing cost initiatives.

Our offer

Air Liquide offers a range of quality gases for the food industry (meat, fruits and vegetables or dairy products and ready meals). As the industry benchmark, our ALIGAL™ products meet HACCP (Hazard Analysis Critical Control Point) standards for production and logistics of all liquids related to the agri-food industry. HACCP is a system which identifies, evaluates and controls hazards which are significant to food safety. Our ALIGAL™ gases adhere to strict quality specifications and go beyond standard regulatory requirements. 


The CRYO INJECTOR- CB3 is a patented, high flow, self-sealing and easily cleanable stainless steel cryogenic injector designed by Air Liquide for bottom injection temperature control applications and using the latest hygiene guidelines from the European Hygienic Engineering & Design Group (EHEDG).

It can be easily retrofitted onto many types of new or used food processing equipment such as mixer grinders and mixer/blenders (with single wall construction).

It offers the versatility to efficiently chill and control the temperature, while ensuring exceptional product quality, during the batch processing of many types of food products. It is ideal for those processors that need increased productivity and ease of operation with a minimal capital investment and installation cost.
