In winter, the vehicle needs to be parked for three to four months, and the materials are prone to freezing; therefore, it is necessary to implement appropriate anti-freezing measures after parking.

For materials that are prone to freezing, the production will be halted next month and they will be stored for several months without any maintenance during that time. What measures should be taken to prevent freezing? Meanwhile, the utility services will continue to operate as usual.
Is there no heat tracing? ? ? ? The parking heating system must not be turned off
If it has to be parked for several months, it’s better to replace it outright. Currently we are conducting pilot tests; one of the materials has a freezing point of 60 degrees, and power outages have occurred, causing the pumps to get clogged immediately
Try not to damage the water system due to freezing. Make sure the equipment doesn’t get damaged by freezing; drain it if possible, disassemble it if possible, and cut it off if possible. Turn on the water system if it can be turned on. Once it stops, one must not slack off. Pilot testing is troublesome. Prepare a detailed plan, paying attention to the low points and the check valves.
Principle: Prevent any pipeline from freezing, avoid replacing any valve, and ensure no equipment gets damaged by freezing. Key points: Displacement, thorough cleaning of materials, nitrogen sealing ； Make use of heat tracing whenever possible; if no heat tracing is available, use electric heat tracing instead ； The interior of the equipment is drained through drainage pipes; for areas where drainage is not possible, shelters are used, and internal heating is provided (via steam or electric heaters) ；
