Hitachi Compressor Oil

Have you tried Googling "Freol UX300"?

Or, Japan Energy UX300 ester

No, you're not. You want someone else to do it for you. That's why you've come here instead of getting Hitachi on the phone yourself. Shame on you!

Thanks.

I have mailed several time to HITACHI but no positive answer from them. It's their chiller and they want to sell only their brand with abnormally high price. That's why I have tried to find similar grade lub oil with other brand, so that I can manage it locally. Other brand like kluber, shell etc.

I have worked on few days on Google and manage to find-out few papers on it. I am working on it and in the same time I have asked for help in this forum, so that those who faced similar problem like me or who have knowledge in this field will help me!!

I think everyone deserve the respect, either I am a questioner or answering to others !!

Aha! One cannot speak to someone in real time on email in the way one can on the phone. Failure to realise that could be the mistake. An awful lot of oil must be needed to justify spending several days getting nowhere...

It appears that here, at least, it is preferred to remain in the dark rather than to light a small candle of knowledge. (Or communicate using a telephone)

One Little Candle

Yes, what said.

A search should get more information that you will get here.

Not to mention the personal satisfaction of accomplishing something yourself.

Make sure you handle this carefully, moisture rapidly contaminates it!http://www.achrnews.com/articles/102899-working-with-poe-oils-requires-forethought ONLY buy it in a metal can, no plastic

If you know why this oil will not work then you know more than me. So why don't you contact Hitachi or anyone who claims to produce FREOL UX300 on R407C with a side of chipped beef.

As I understand any synthetic oil with viscosity 68 will do the job. But I need further clarification.......

Then go back to where the understanding was received and ask that source for the clarification.

The three main classes of refrigeration oil are mineral, alkyl benzene, and polyol ester. Mineral is the older, traditional version. Alkyl benzene is newer, and usually compatible with the older mineral oils, meaning that you can usually just drain the old oil and put in the new. Polyol ester oils are a different class, usually requiring solvent flushing of any older oil before installing the newer. If you find out which of these classes your Freol is, you can normally replace it with the same class from another manufacturer, but you should confirm this with the newer manufacturer.

I wonder what hopeless dingaling voted that OT.

I've "searched the world over" and can't find any reference to this stuff.

It is POE. HFC gas should be using synthetic Lubricant POE. You can apply Xaerus Performance Fluids Lubricant: XR 534 series. Regarding the viscosity, you can simplify choosing the proper one as following:

- Piston/Reciprocating: 32/46/68

- Screw: 120/170/220/320

- Scroll: 32/46/68

- Centrifugal: 68
