Due to friction and compression pressure, the compressed air temperature of screw air compressor is maintained at 65ºC - 90ºC. However, after period of use, the compressed air temperature can be up to 95ºC - 110ºC and even higher, causing the machine to stop working. Users should pay attention to this to have an early fix. The cause may be due to one or more of the following factors:

CAUSES
SYNSTOMS
REMEDIES
-Dirty compressor oil :
+ Machine operates in long timwe without oil replacement, dirty oil decrease heat dissipation capability
+Poor quality or incorrect type of oil.
+Oil level is too low
+ Oil is black and muddy + New oil has changed color abnormally even though the machine runs in a short time. Oil is bubbling.
+ Replace new oil. When replacing the oil, you must make sure that the old oil is removed (in the oil case, oil filter, cooling system and air end) + New oil must be specialized oil of screw air compressor.
Lack of oil: + The amount of oil enough for operation of the machine is within 2 red lines of oil level gauge when the machine is operating
+ The amount of oil is lower than the bottom line
+Replenish more oil
Oil cooling fan is broken
The cooling fan is broken, not rotating or weakly rotating
Replace or repair
The cooling system is clogged or the oil circulation is blocked,
The temperature difference between the two oil circulation poles is low.
Remove the cooling platform and use a specialized solution (eg Butin) to clear.
Suction throtte valve and temperature control valve is broken
Check if the oil is cooled when going through the cooler
Check oil suction throtte valve And repair or replace the temperature control valve if nescessary.
Oil filter is clogged
The pressure difference between the two inlet and outlet outlets of the oil filter is high.
Replace oil filter
Cooling fan is broken
It doens't spin or weakly spin
Repair or replace cooling fans and electric motors
Mechanical collision: + Bearings are worn, broken balls + not concentric + Screw or mirror surface is deformed
Abnomal noise .
Replace and recalibrate . Check screw, mirror surface
Ambient temperature is too high
measure the ambient temperature
Improve ventilation and reduce room temperature
The side cooler is clogged
Clear it
Failure of thermal sensor is signaling to the instrument panel incorrectly.
Unstable temperature
Check and replace thermal sensor
