Harvest the benefits

Since 1984, we have installed numerous Deepchill® systems onboard trawlers, seiners, long-liners, and large factory vessels. Our fully automated systems are simple to operate and require minimal maintenance.

Deepchill® keeps your fish colder and fresher for longer, enabling you get the most out of your fishing trips. Deepchilling maximizes the freshness of your catch, from the sea to shore, so that your clients can enjoy a truly “Ocean Fresh” quality seafood.

The Deepchill® Difference

Higher quality, longer shelf life, even more efficient operation – every advantage that you can seize for your fishery helps enhance your profitability. Deepchilling is a highly advanced cooling and preservation process that can help you improve your onboard processes and harvest the greatest profits from your catch.


Consistent, fast cooling

Deepchill® slurry completely surrounds your fish from top to bottom of the container or hold, resulting in fast, uniform cooling and consistent quality throughout. This rapid cooling delays the start of rigor and prolongs shelf life.


Superior protection

Deepchill® suspends and protects your fish, preventing surface damage. There are no sharp edges like conventional ice that can bruise or damage the fish surface, nor is there any intense agitation as with Refrigerated Sea Water (RSW).


Easier handling

Deepchill® is free-flowing and can be pumped anywhere, making it easy to distribute and to quickly handle large catches with a limited crew, saving labour.


Extended trips

Deepchilling’s superior preservation allows for extended time at sea. This means a higher yield per trip while still maintaining quality of your fish until processing.

Deepchill® vs. RSW

Each individual Deepchill® crystal already carries cooling energy needed, allowing Deepchill® to rapidly chill and maintain sub-zero temperature of the fish without external refrigeration.


When warm fish enters pre-chilled RSW water, the temperature rises significantly, and as a result it takes many hours for the RSW system to cool the fish to ~2ºC. The system must also continuously run to keep water chilled. This continuous and intense circulation of RSW may cause damage to seafood products.

Wet fish vessels


For boats that land fresh unprocessed fish, Deepchill® offers the ideal cooling and preservation system to chill large quantities of fish quickly, uniformly and efficiently. Whether you store your catch in stacked containers or keep the fish in bulk in the fish hold, Deepchill® helps you maintain peak freshness for longer, maximizing the length of your trip after catch without compromising quality.

Maintain freshness throughout your trip

1. Harvest

Deepchill® is generated and ready to be applied as soon as fish is harvested to stop deterioration of fish


2. Deepchilling — containers

Deepchill® is pumped directly into containers, providing rapid, uniform cooling. Fish is homogeneously mixed with Deepchill®.

3. Storage

Deepchill® inside containers fully surrounds the fish and packs the container, maintaining fish at the ideal temperature to preserve it throughout the trip. Deepchill® protects the fish from drying, retaining its moisture.


2. Deepchilling — fish hold

Fish are deposited into the hold partly filled with Deepchill®. Fish is homogeneously mixed with Deepchill® and uniformly chilled.


3. Storage

Deepchill® fully surrounds fish maintaining it at ideal temperature to preserve and protect from damage throughout trip. Unlike RSW, the enormous cooling energy stored in Deepchill® can keep large amounts of fish at sub-zero temperature without external refrigeration.


Factory vessels


Whether you freeze your catch at sea or process onboard, Deepchill® allows you to cool large quantities of fish rapidly and uniformly prior to further processing or freezing. Deepchill® preserves your fish in the best condition while increasing the speed and efficiency of your processes.

Rapid chilling for optimal processing

1. Harvest

Deepchill® is generated and ready to be applied as soon as fish is harvested to stop deterioration of fish.


2. Pre-chill

Deepchill® is pumped into HeliX DeepchillerTM or holding tank to rapidly chill and preserve the fish in the best condition before processing.


3. Temporary Storage

Deepchill® can be used in different stages of processing to stow and maintain temperature of the fish – allowing a smoother operation and avoiding bottlenecks.


4. Freezer

Processed fish is stored in the optimal form of Deepchill® to maintain fish at sub-zero temperature, and prevent mechanical damage or contamination. In case of frozen-at-sea fish, freezing capacity is increased up to 20% since fish is properly pre-chilled before entering freezer.


Designed to fit your vessel

The Deepchill® system offers flexible layouts and modular configurations sized and designed to fit your onboard operations. Systems are fully automated, easy to operate and simple to maintain.

Modular Deepchill® systems can be installed on retrofit or new vessels, and can be fitted all in one location or designed to be split into multiple locations across multiple decks if necessary.
