The block ice, comparing with the flake ice and the cylindrical tube ice, has a dominant advantage over others, especially in the developing countries and the high-temperature areas. The block ice has the longest melting time than other types of ice.

When we talk the stationary block ice plant, we usually mean the ice plant that produces ice at hundreds of tons of ice per day. And the stationary block ice plant is a complete installation of the following equipment or systems:

• Thermal energy storage for chilled water;
• Water chiller or water chilling system;
• Block ice-making equipment (brine refrigeration technology or direct evaporation technology);
• Refrigeration system (Ammonia system or Freon system);
• Cold room for ice storage;
• Ice delivery system;
• Ice crushing equipment.

Refrigeration system – Ammonia or Freon

In the refrigeration industry, there is always the debate of whether to choose ammonia refrigerant or one of the "Freon" refrigerants. For more details about the ammonia refrigerant and the Freon refrigerant, please read at this page. They may have their own points of view from the aspects of the refrigeration efficiency, environment and safety, no matter which type of refrigeration system you choose, SFT has the capabilities to build the stationary ice plants on the basis of ammonia refrigeration or Freon refrigeration system.

Ice making technology – Brine Refrigeration or Direct Evaporation

The brine refrigeration is the oldest technology that usually used in vast areas. Most of the old block ice plants are applying the brine refrigeration system. The operation of the brine system is easy, though the ice harvest time is quite long and the working efficiency is quite low. When the direct evaporation technology was invented several years ago, the direct evaporation system has a much higher working efficiency than the brine refrigeration system.
