 The North Star Liquid Ice Advantage
At North Star, we are proud to offer the best ice making options for fishing, aquaculture and seafood processing companies. For over 60 years, we have produced the leading flake ice makers in the business and installed them in seafood operations around the world. Now we offer even more – a seawater liquid ice generator with the reliability and performance the seafood industry has come to expect from North Star.
North Star liquid ice generators offer a number of benefits you can’t find in other slurry ice machines.
- Reliable – North Star delivers a dependable generator that produces seawater liquid ice using proven technology. All units are constructed to 150 PSIG working pressure ASME code with inspection and test certificates furnished.
- Minimum salinity – Our liquid ice generators make seawater liquid ice with a minimum salinity of 2.5%. This allows North Star to apply seawater directly to the ice generator freezing surface. Other liquid ice makers require 3.5% salinity, requiring a brine make-up tank to be added to the system.
- Meets all food processing standards – North Star evaporator and water path components are stainless steel – the first and best choice for food processing.
- Compact – The smallest footprint with the largest ice capacity in the industry.
- Pumpable ice – North Star liquid ice can be pumped anywhere you need it using small diameter PVC piping.
- Versatile – Designed for shipboard or land-based applications. Ice discharges to progressive cavity pump or mixing/storage tank (by others).
- Flexible – Can be operated with either ammonia or halocarbon refrigeration systems. Multiple refrigeration units are not required.
- Energy Efficient – Protected with high R-value polyurethane insulation and reinforced fiberglass exterior.
- Lifetime warranty – Backed by the best warranty in the business – North Star’s lifetime evaporator warranty.
