Chiller Knowledge

How Long Does the Cold Water Machine in the Lab Need to be Cleaned?

After running for a period of time, Lab Chiller CDLJ -115℃～-50℃ requires for the protection and the maintenance of all. If the laboratory chillers lack the necessary maintenance and protection, it means the high operation defect rate of the laboratory chiller.

When running laboratory cold water machine, it needs a thorough clean for the machine to keep the laboratory machine safe and stable after using half a year’s time.

If cooling water machine for laboratory use frequency is higher, and the environment is relatively bad, to avoid the probability of all kinds of problems of industrial laboratory cold water machine, you should be able to shorten the clean time to once every three months.

The specific time about cleaning the laboratory water chiller is determined by using environment of the company. If the environment is relatively clean, the company can put off cleaning time, whereas company needs to clean it ahead of schedule in order to keep the laboratory chiller operation safe, prevent all kinds of problems in case to affect the company normal use of laboratory chiller.
