1. Implement anti-freezing measures for electronic drain valves and piping systems.
Compressed air from the air compressor contains some moisture. When condensate is discharged through the electronic drain valve, it can freeze in the pipes or other parts due to low temperatures. In low-temperature environments, all moisture-carrying pipelines and equipment in the system, as well as all drainage lines, should be insulated and heated to prevent freezing.
2. Implement anti-freezing measures for the air compressor unit.
If the air compressor unit is indoors, heating facilities should be provided to maintain the indoor temperature above 0℃; if installed outdoors, an insulated container should be used. As the temperature drops, the viscosity of the air compressor lubricant increases, making it more difficult to start the air compressor and potentially reducing its service life.
3. Check the condition of the air compressor, air tank, dryer, automatic drain valve, etc.
When the equipment is shut down, be sure to open the drain valves of the air compressor, pipes, air tank, dryer, etc., and close the valves only after the condensate and gas in the equipment have been completely drained and dried. This prevents pipes from freezing and cracking and reduces the damage caused by condensate to the equipment.
4. Protect the lubricating oil.
Low temperatures shorten the service life of lubricating oil, so the oil change cycle should be shortened accordingly. Lubricating oil should be stored in a heated room to prevent it from solidifying due to low temperatures, which could prevent its immediate use in an emergency.
