After running for a period of time, the normal operation of ultra-low temperature circulating water chiller needs comprehensive maintenance and maintenance. For many enterprises, due to the weak consciousness of daily maintenance, the cryogenic cycle water chiller has been used for a long time without maintenance. If the low-temperature cycle chiller is lack of necessary maintenance, the failure rate of the ultra-low temperature circulating water chiller will be pretty high in the later period.
There will be a large range of incrustation problem after an industrial long-term cryogenic operation of circulating water chiller. If the incrustation cannot be effectively cleaned up, the range of incrustation will continuously extend after a long time of accumulation, which will directly affect the industrial circulation chillers of ultra-low temperature.
If the ultra-low temperature recirculating chillers frequently used in a hostile environment, shorten the cleaning time to three months in order to reduce the probability of all kinds of malfunctions of the industrial ultra-low temperature chiller.
As long as there are some problems such as the increase of energy consumption, the comprehensive cleaning, and maintenance of the industrial ultra-low temperature circulating water chiller can be carried out. Proper cleaning and maintenance can extend the service life of ultra-low temperature cycle chillers, and avoid all kinds of faults to affect the safe operation of industrial ultra-low temperature cycle chillers.
