Where Koller Ice Machines Work in the Fishery
Freshwater vs Seawater Ice Machines for Fisheries
Koller ice machines run on both fresh water and salt water — the right choice depends on where your ice is produced: on shore or on board.
Freshwater Ice Machines
On-shore plants, markets & storage- Ice types: flake, block, cube and plate ice.
- Flake ice plays a crucial role in seafood processing plants for rapid cooling, transportation and preservation of seafood.
- Block and cube ice suit longer preservation and transport of perishable goods.
Seawater Ice Machines
Fishing vessels & coastal operations- Ice types: seawater flake ice and seawater slurry ice.
- Flake ice machines are commonly installed on fishing vessels to produce the required ice on the go.
- Slurry ice machines feature a compact structure and size that can be used on boat, with anti-corrosive food grade 316 stainless steel.

Fishery Cooling & Freezing FAQ
Which type of ice is best for preserving fresh fish?
Flake ice is the most widely used choice for fresh fish: its smooth edges cause no damage to the product, and it works for both fresh water and salt water fish. For premium seafood preservation on board, slurry ice freezes products efficiently with the largest contact area.
What type of ice do fishing boats use?
Fishing boats often use flake ice for their on-board ice needs. Its small, versatile flakes surround the fish and evenly distribute the cooling, helping to maintain an optimal temperature while minimizing damage to the catch. Flake ice machines are commonly installed on fishing vessels to produce the required ice on the go.
What is the difference between flake ice and block ice for fish?
Flake ice has smooth edges that cause no damage to your products and is available for fish in fresh water and salt water, with ice ready in less than a minute. Block ice keeps fish preservation lasting for a longer time, and its cooling range can be intensified with an ice crusher when needed.
Can ice machines be installed on fishing vessels?
Yes. Flake ice machines for salt water are commonly installed on fishing vessels to produce ice on the go, and salt-water slurry ice machines have a compact structure and size that can be used on boat, built with anti-corrosive food grade 316 stainless steel.
Does salt water ice last longer than fresh water ice?
Saltwater ice can actually last longer compared to freshwater ice. Adding salt to water lowers its freezing point, resulting in a slower melting rate, which is beneficial where extended cooling duration is desired in marine or saltwater environments.
Can Koller ice machines run on sea water for fishing boats?
Yes. Koller manufactures flake ice machines for salt water and slurry ice machines for salt water, designed for onboard and harbor use in fishing operations.
What temperature does a blast freezer for fish reach?
Koller blast freezers reach freezing temperatures of -30°C to -40°C, with fast cooling speed and an adjustable temperature system. Walk-in freezers hold -25°C to -12°C and walk-in coolers hold -12°C to +5°C.
Can cold rooms be customized for a fish processing plant?
Yes. Layout drawings are designed based on your idea and tailored to your satisfaction. Panel material, room size, door type and temperature (from 5°C to -40°C) are all customizable, and containerized cold rooms are available up to 30 tons.
What warranty do Koller machines carry?
All machines carry a 1-year warranty covering free repairment and components. Beyond the warranty period, the same service is still provided at cost.
