Protecting the value of your product

A growing global demand for fish and seafood products has heightened the need to increase productivity and minimize yield loss of this delicate protein. From growth to production, we can help you optimize your process and equipment to meet your goals. With our pre-chilling and quick freezing systems, you can lock in natural moisture and reduce bacterial growth to deliver high quality seafood to your customers.

Related Gases

Carbon Dioxide Carbon Dioxide rollover Carbon Dioxide

Carbon dioxide protects the taste and texture of your seafood products by maintaining proper temperature control in cooling, chilling and freezing applications.

Nitrogen Nitrogen rollover Nitrogen

Nitrogen is a key cryogenic agent in cooling, chilling and food freezing processes. And because of its extremely cold temperatures, liquid nitrogen is an essential part of immersion freezing, the fastest method known for producing individually quick frozen (IQF) foods.

Oxygen Oxygen rollover Oxygen

Critical for life, oxygen is used in aquaculture to deliver the dissolved oxygen levels that are needed for high production levels, increased pond population density and fish health.


Freezing and Chilling Shrimp

Removing heat quickly and uniformly is vital to maintaining the quality and integrity of your seafood. A rapid, thorough chill retains the moisture and natural attributes that make your product unique and delicious. Praxair ColdFront™ freezing systems provide accurate, repeatable and affordable chilling when and where you need it.

CO2 Snowing

Removing heat with carbon dioxide snow is an economical and precise way to cool your seafood products at any point in your production. Praxair snow dispensing devices are available in a wide range of sizes and types, and can stream CO2 snow from any orientation. Plus, the snow particles are more consistent and uniform, allowing for cost-effective snow cooling.

Modified Atmosphere Packaging (MAP)

Modified Atmosphere Packaging

Replacing the air in a seafood package with a precise gas mixture allows the product to stay at its best for longer. Choosing the proper atmosphere means achieving the right combination of gases to reduce the growth of bacteria and prevent discoloration. Praxair's ExtendaPak™ line of gas mixtures helps ensure you get just the right atmosphere for your seafood product.


Maintaining oxygen levels in your aquaculture system is critical to the success of your operation. Delivering pure Praxair oxygen to pond water results in much greater transference rates, compared to air-only systems. With precise oxygen level monitoring and delivery, your system can maintain and shift oxygen levels, as needed, to help you increase yield and meet higher production goals.
