The discharge temperature of the screw compressor is high; it shuts down at 100°C. I’m seeking advice from those with more experience

It is a screw compressor with a volumetric flow rate of 450. The water used for cooling via spraying is at 42°C, the inlet air temperature is 38°C, and the exhaust pressure is 0.35 Mpa. Under these conditions, the exhaust temperature gradually rises and exceeds 100°C, forcing the machine to stop operating; the total operating time was 2.5 hours. Dear experts, what could be the possible causes of this issue? I would like to thank everyone first:dizzy:
If the installation meets the design requirements, then check the water circuit to see if it is suitable for the designed working medium.

I’ve considered the possibility that debris attached to the intake pipe might be causing the issue, but the vibration, displacement, and temperature of the screw compressor are all normal
If the machine is fine, then there’s no problem. Removing the heat of compression is key; look for the cause from that perspective.
How often should the absorbent oil be replaced? There are many components in the medium that are prone to liquefaction; failure to absorb them often leads to high temperatures and reduced efficiency.
Did the poster choose a spray screw type unit? If the compressor is operating stably with no other issues, please check the spray water pipeline: first, ensure it is unobstructed; second, verify that the flow rate is sufficient. In areas with dry climates, the humidity can cause the spray water to evaporate, so it is necessary to replenish the water promptly.
What is absorbent oil? I use a screw compressor with spray cooling here, and I haven’t heard of any absorption oil being used. . .
Oil absorption is carried out at the compressor inlet, with diesel generally being used as the absorbent
The water used for spraying here is also counted as part of the consumption; water meters are installed before the compressors, so there is definitely a flow of water. When the spraying water connection of the compressor is disconnected, the amount of water is quite large as well
