The laboratory ice machine is mainly used to carry out experiments related to life sciences, to provide samples with an ice bath environment, to prevent samples from degrading or deteriorating due to temperature changes, so as to ensure the accuracy and effectiveness of experimental results. Although the influent water used by the ice machine does not directly enter the experimental system, there are some water requirements, so some filtration devices should be used to treat the influent water to remove impurities.

I. Purpose of installing water treatment device

1. Improve the quality of ice crystals

2. Reduce the corrosion of residual chlorine on the evaporator of the ice maker

3. Reduce the failure rate and prolong the service life of the machine

4. Reduce maintenance costs

II. Commonly used raw water filter media

1. Depth filtration: Adsorb and randomly capture suspended particles in the influent water as a physical barrier to prevent the protected parts from being polluted and clogged.

2. Activated carbon: It can chemically adsorb substances of various properties, and remove odors, organic matter, colloids, residual chlorine, etc. in water.

3. Softener: When the concentration of calcium and magnesium ions in water is high, it will precipitate and form scaling, which will damage the pump, evaporator and other components of the ice maker. Softening resin or scale inhibitor are commonly used.

For laboratories, we usually choose the snowflake ice making machine to produce snowflake-shaped crushed ice. Due to the small particles and fast cooling speed, it can enlarge the contact area between the tube wall and ice to ensure the ice bath effect. The ice making machine can be equipped with an influent water treatment device with only a simple filtering function. If there are special needs, a special laboratory water purifier can also be used.
