The reliable ZIEGRA trawler ice machines have been in service on board ships for over 30 years. The ice does not have to be brought in from land, but rather can be produced on site as required when fish are caught.
Your benefits with ZIEGRA trawler ice machines:
Three types of ice machines are recommended for installation on trawlers:
Combines the production of all three types of ice in one machine – the required type of ice can be produced by a simple setting.
The machines are delivered ready for connection to electricity and water supplies. A high voltage connection and a pump to supply the trawler machine with seawater are required. A connection to a water tank is required if the machine is to produce ice from freshwater. The water quantity required for ice production corresponds to the required quantity of ice (e.g. 150 l of water = 150 kg of ice).
has the ideal temperature of -0.5 °C, and is therefore particularly gentle to fish. Due to its irregular structure, the ice always remains loose and easy to handle. It never freezes together. ZIEGRA chip ice has no sharp edges, and therefore cannot damage the fish that are being cooled. It is ideal for the extended storage of high-quality fish.
The temperature of saltwater ice is approx. -7 °C. It cools the fish quickly and intensively. Due to the salt content, ice made from saltwater is softer than flaked ice, and has no sharp edges. The fish is not damaged.
The unlimited supply of seawater can be used for ice production. The trawler ice machine is designed for heavy-duty use, and copes easily with different salt contents.
Depending on the density of the ice, the temperature of StreamIce varies between -2 °C and -3 °C. Due to its liquid form, it guarantees complete enclosure of the fish, and is therefore particularly expedient for rapid cooling. The ice density can be varied between 15 and 55%, depending on the intended use. The higher the density, the more suitable the ice is for the storage of fresh fish. If the water in the box is allowed to escape, the ice crystals collect evenly around the fish, cooling it for up to several days. Due to the fact that it can be pumped, StreamIce can be easily supplied to the point of use by a corresponding system: laborious shovelling is no longer required.
