Ice block machine has three cooling ways: water cooling way, air cooling way and evaporating cooling way. Some huge ice block machine adopt evaporating cooling way, but this kind ice block machine capacity is always 100 tons or above.
- Air cooling way is used in small capacity ice block machines, such as 1ton, 2ton and 3tons. The advantage of air cooling is taking up small space and easy to install.
- Cooling water tank is needed for the water cooling, and should be installed outside, But water cooling is more steady than air cooling, and it is cheaper. So when you choose water cooling way ,the ice block machine is made of three parts: ice block machine units, salt water tank and water cooling tower.
- As for the compressor, there are lots of world-famous brand, such as Germany brand Bitzer, American brand Copeland, French-brand Manevrop and so on. When you choose Compressor, you should consider your local power, generally Bitzer and Manevrop is fit for 380v, 50hz, 3p while Copeland is suitable for 220v-240v,60hz,3p.
And ice block machine generally has 2 kinds refrigeration: R22 and R404a.
R404A is more environment-friendly, which is popular by many European customers, but it is expensive than R22.
In a word, when you are going to purchase ice block machine, please consider those above so that you can purchase the most suitable one.
