We have 30 gtc model air cooled chiller problem is water intered in the compressor but we opened the cooled and given the pressure to the cooler but there is no leakage in the cooler then from water is came in the compressor

You are going to have to try to dry out the refrigerant by replacing the drierd and pulling a good revaucuation on the unit after you replace the drier that are in the refrigeration lines .

Can you elaborate? What kind of a chiller is it? Recip, screw, centrifugal? Air cooled, water cooled? How many tons? What refrigerant? What are you considering to be an unsafe suction pressure? What’s the superheat and subcooling? EXV? TXV?
My point is, absolutely no way anyone can help a generic question on a complicate system such as a chiller.
The cost of one of those compressors is over $100. When you factor in tax and labor you're better off junking it. Its also possible you have a compressorless cooler called Peltier.
The Freon is probably a bit low. When the compressor draws from the low side the extreme low pressure trips the low pressure switch, shutting down the compressor. With compressor off the pressure equalizes the low pressure switch opens and the compressor switches on. murf427
Without more info or knowing your compressor my first question to you is,is the oil cooler clean and does the unit have good water flow. DO you have good water flow / pressure. The oil level should be about half way the sight glass running loaded. If the oil level was low ,when the thermostat opens it allows oil to flow to the cooler which lowers the oil level.Typical problems during this time of year are , , dirty oil cooler, Faulty thermostat, Faulty element temperature sensor, Low oil levels and bad oil. Also dirty oil filters restrict oil flow and can cause high element temp. problems. Try back flushing the water side of the oil cooler. Have you checked to make sure the water solenoid is opening. May have a bad coil or valve. May also have water solenoid plugged with something. What is the cooling water inlet temp and outlet temp. The W usually indicates water cooled. If not water cooled, most of the above also applies to air cooled units. just replace water with air if it fits.
On a chiller with semi hermetic compressors can have different types of thermostatic expansion valves for metering. As far as a number, you will have to go to the evaporator to look at the tx valve and get the numbers. It may be a single ported, double ported, be externally equalized or not. You have to get the copper line sizes in and out also if you are planning to change the valve out. The valve will also have the type of freon the system uses if for some reason the data plate is worn off. That's the place to always find out is the expansion valve. If you need information other then what I have given you, contact me and I will help you. Sincerely, Shastalaker7
