DESCRIPTION

PROJECTS

The block ice machine with the direct evaporation system works by the principle of direct heat exchange between the water and refrigerant. Comparing with the brine refrigeration system, the direct evaporation system does not apply brine water as the cold medium to transport the heat. Meanwhile, we adopt the aeronautical aluminum alloy as the ice evaporator material, which has higher heat conductivity than the ferrous materials, therefore the ice formation and harvest efficiencies are greatly improved when we use the aluminum evaporator.
Meanwhile, The aeronautical aluminum evaporator has a better anti-corrosion ability than ferrous materials, the hygiene of the ice can be guaranteed. And also because of no direct contact between water and the refrigeration medium, there has no chance to contaminate the ice.
Features

  • Skid mount design ensures the easiest commissioning;
  • Advanced technology to guarantee less energy consumption;
  • Automatic operation, less maneuver interruption;
  • Hygienic ice and quality ice guaranteed;
  • Environment safe, no brine pollution to the environment;
  • Gas available with R22, R404A and R717;
  • Optional for the mobile ice plant, more advantages and profit.

Applications

  • Cooling
  • Fresh keeping for aquatic products
  • Food preservation
  • Ice factory of the ports and docks
  • Distance transportation
  • Special areas of cooling
  • Chemical processing
