With a significant drop in temperature, how to properly control the oil temperature of the compressor lubricant.
Thread Content
Over the next two days, due to the advance of strong cold air from the north, a cold wave will bring about a significant drop in temperatures. The temperature of the lubricating oil in the machinery will also decrease, which can affect the safe operation of the compressors. At an ambient temperature of 18°C, the oil temperature of our compressor is around 35°C, and the unit’s oil cooler is in operation. Let’s discuss how to control the oil temperature of the unit’s lubricating oil in the event of a significant drop in temperature. (Apart from using electric heating for lubricating oil)
Adjust the circulating water volume appropriately; additionally, the fans in the circulating water system can also be turned off to help maintain a higher water temperature
Insulate the lubricating oil pipeline or install a heat tracing wire.
When the temperature is dropping, reduce the inlet valve of the oil cooler’s cooling water, and continue to make adjustments based on changes in air temperature as well as oil temperature and pressure. Generally, in the north, the entrances are closed a bit at night, especially in the early hours, and then opened wide again once it gets warmer during the day.

Reply to 5# chengbaocang: Turning down the cooling capacity of the cooler is a good idea. I’m worried that the cooling water might freeze, which would create even more problems. In our coolers, the flow rate of water is usually not very high; turning it down further isn’t possible.
If you don’t want to turn off the coolant inlet, then turn off the outlet, or reduce the pressure to raise the water temperature; if that doesn’t work, use an electric heater.
Turn down the cooling water a bit, but don’t let it freeze! The postal and telecommunications heater has been turned on; no heat tracing is used, but be careful not to let the oil temperature get too high! It’s actually bad for the engine!
Strictly control the temperature of the circulating water outlet; use the oil-cooled water supply pipeline to regulate this temperature. Additionally, it is advisable to install an automatic control valve on the oil-cooled water supply line when the device is shut down for maintenance, as this will help maintain a stable oil temperature, which is beneficial for the long-term operation of the machine.
