Dewatering 3000l Gargoyle Artic SHC NH 68 synthetic oil

Read our primer articles on Desiccant Breathers and Oil Filter Carts.

Hi,

We want to reduce the water content in our oil, 3000l Gargoyle Artic SHC NH 68, from 300 ppm to < 50 ppm.

What is the best way to do this? Purifier? Adsorption? Absorption? ....

The oil is 100% saturated with NH3. It's a compressor oil. This causes some problems with the use of vacuum dehydrators...

The oil temperature is minimal 80°C and max 120°C.

Any suggestions?

Kind regards,

Hanne

Not sure why you are having problems with a vacuum dehydrator but we have done this before with a vacuum distillation unit. I have one available in Calgary if you are interested, please send me an email.

Hanne,

Is it screw compressor?
Is the lube oil tank is pressurized? if yes it may around 12 - 21 barg, isn't it?

In this case....No, you cannot use vacuum Dehydration System.
If you want to, Coalescer System may be help.

But your concentration of water only 300 PPM
I don't think so, that it is really water.
It may only chemical reaction of Karl Fischer agent and PAG oil, which resulting (detected) as water.

For PAG Type of oil, i put alert on 2000 PPM and 4000 PPM on critical

Consult the technical support of your oil supplier.
