COLD STORAGE MAINTENANCE STEPS – Periodic Preservation
Cold storage after being used for a long time is often difficult to avoid unexpected problems for certain reasons. Therefore, we need to periodically maintain the cold storage to ensure good operation, improve the life of the warehouse and the machine, and avoid the bad case that may happen to the cold storage. Normally, we should check and maintain cold storage periodically from 3 to 6 months.
What is the problem that your cold storage is using?
The indoor unit is frozen?
Warehouse not running at the right temperature?
The amount of power consumption for hard too much?
Are you worried because of high-value preserved products that have not yet been able to control the operation of cold storage?
Are you looking for a solution to alert, handle, repair, troubleshoot?
Reasons for regular cold storage maintenance:
The warehouse operates stably, with few problems.
Consume the least power
Extend the life of machines
Ensure products are stored at the correct temperature to limit unnecessary damage
Save the cost of repairing machinery if the problem is detected in time
