Liquid Ice Generators

North Star offers efficient and dependable seawater liquid ice makers. Our liquid ice makers offer a number of benefits you can’t find in other slurry ice machines.

Equipment Features

Ice makers used for seafood


North Star delivers a dependable generator that produces seawater liquid ice using proven technology. All units are constructed to 250 PSIG/10.3 bar 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%, allowing 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.


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.

Liquid ice maker


Designed for shipboard or land-based applications. Ice discharges to progressive cavity pump or mixing/storage tank (by others). Integrated control panel operates all system components.


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.


North Star liquid ice makers are available in five models ranging in capacity from 18.6 to 158 tons (16.9 to 143 MT) of liquid ice per 24 hours (based on an ice slurry of 25% ice and 75% water). All North Star liquid ice makers are backed by North Star’s lifetime evaporator warranty.
