A new standard for pelagic processing – Meet the H6 Freezing System
Optimar continues to set the global standard for seafood processing with the H6 Freezing System. A system that demonstrates how innovation provides unmatched capacity and product quality.
The H6 AutoFreeze series features a food-safe and hygienic design perfectly suited for both land-based use and for any demanding freezing environments. The H6 freezers are equipped with Optimar's patented compact chain pusher, allowing full emptying of the freezers before defrosting and washdown. The loading and unloading elevators operate independently of each other, securing full flexibility during all operations.
- H6 AutoFreeze CTS™ . Built for continuous loading and unloading, this powerful and compact freezer can handle an impressive 60 to 100 tons per day. A full plate stack pressure mechanism guarantees maximum contact surface and minimum freezing time. For ultimate flexibility, the CTS model can also be configured for use as a multipurpose batch freezer.
- H6 AutoFreeze CTS Double™ Same as the CTS - this design is made to maximize the utilization of both space and equipment. Sharing multiple freezing stacks for one feeding system - this will drastically lower the investment when high capacities are needed. For each added stack, the capacity will double.
The stainless steel freezers can be fitted for both CO2 and ammonia. In addition, the freezers can be delivered with constant pressure to maximize the freezing capacity by keeping full contact even while filling the freezer. No matter your needs, the freezing system is designed to be easily adapted to fit your operations. Some examples of the tailoring we offer are:
- Number of stations
- Size of freezer plates
- Number and size of cartons
- With/without freezer frames
- With/without constant pressure
- Number of freezer stacks per feeding system
- Automatic washing system
- CO2 or ammonia
The volume of refrigerants can be reduced by 70% if choosing our Premium Freezing Plates.
The Nordborg Success Story
To see the true capacity of the system in action, look no further than the 81-meter-long Faroese freezer trawler Nordborg. Optimar is currently supplying a fully automated onboard processing system that covers everything from sorting and freezing to packing and palletizing.
A central component of this groundbreaking facility is the newly developed horizontal freezer, which significantly improves product quality while ensuring a more ergonomic design with no heavy lifting for the crew.
– We're combining our unique experience from land-based pelagic facilities with our specialized expertise in onboard production, says Senior Sales Manager in Optimar Trond Bjørnøy.
Quality verified: FAT testing the Nordborg solution at Optimar Valderøya
The Nordborg installation ensures full control of product quality, catch time, species, and temperature through advanced traceability technology, tracking each product from catch to completion.
– The system can handle up to 200 tons per day of herring, mackerel, and blue whiting. It's a seamless design that significantly reduces manual labor, improves product quality, and delivers major energy savings, adds Bjørnøy.
– Together, we've created a solution that not only meets current requirements – it sets a new global standard for pelagic processing at sea, Bjørnøy concludes.
