Fellow users:
I am in need of help. We have experienced a major contamination event of our steam turbine EHC Fyrquel system. The contaminate appears to be a transparent gel type material, similar to uncured clear RTV caulking. We can collect quantities of this substance from the side walls of the reservoir as well as from inside the delivery pipes. We are in the process of doing a full system flush including changing servo valves. Has anyone ever experienced a contamination issue like this? Does anyone have a recommendation as to what caused this type of reaction? Does anyone know of a lab that can analyze down to the molecular level to tell us what happened so that we can prevent a re-occurrence? A full root cause analysis is in process now, but I would appreciate hearing responses from all with similar experiences. Thank you

We have seen it a million times...send me your email and I can show you pictures of what the "Apple Jelly" like gel formations you are seeing.

A couple quick questions for you:

1. currently does your system have a fullers earth or selexorb filters?

2. if so, which one?

3. Do you have the last oil sample report from Supresta?

Hi mrowe, as we have also seen this issue several times. Often we find out the root cause is excess water reacting with the phosphate ester to form free acids.

The acids which are formed can;
- catalyse further degradation of the fluid.
- cause corrosion at high concentrations.
- reduce fluid resistivity & promote servo-valve erosion.
- react with the conditioning medium to form metal soaps which cause foaming and poor air release.
- condensation polymerisation to form insoluble polyphosphate gels.

If you would like additional information on the tests we suggest to keep this from happening again please feel free to contact me.
