What type of oil cooler do you have if any, water cooled?

Hi mostafaabdalla4
Ranger1's question is completely relevant as dependant upon what type of cooling you have.
Greatly affects oil operating temps and their control settings.
Also how your Comp is set up to load up and down could be an issue?
What is your oil temp cut-out set too?

If you have a thermo syphon oil mounted below liquid receiver then the oil cooler has oil in refrigerant circuit as well.
Reason for high carry over to system possibly compressor load rates too fast during pull down of blast freezer.

Adjust the valve no.123 injection of oil on the rotor.

Re: SAB 151 E high oil temp trip
Hi mostafa
you wort your oil temp is high, why you changed the oil ? what is the reason for that?
you have to look for oil cooling system ( water -- thermo syphon --air ) also check the ECO system and also liquid level in system and filters in ECO. line
