2. Low Dilution Corrosion due to no inhibition.
System wear due to no lubrication.
Increased contamination due to increased wear.
Bacterial growth as the fluid is biodegradable when diluted.
High pressures required to operate valves
Slow system response.

3. Poor water used for mixing
Bacterial contamination (even with drinking water)
Introduction of other chemicals used in water treatment can cause reactions with the fluid.
Main affect normally on corrosion inhibitors.

4. Oil & Grease Contamination
Blocked filters
Micro-Biological Contamination.
Live in the Oil
Feed from the fluid
Fluid
Bacteria
Oil

5. Addition of Antifreeze
Only Erifon Stack Glycol or pure Mono-Ethylene-Glycol (MEG) should be used
Use of standard antifreeze may have a detrimental effect on the fluid.

6. Contamination with Other BOP Fluids
Oil based fluids are not compatible in any proportions.
All Erifon products are compatible with one another.
Erifon fluids are compatible with Stackmagic and UK50 but we would recommend speaking to Wm Canning before mixing any others.
We don’t advise mixing concentrates.

7. Oceanic ACL Grease Grease based on MEG
Fully compatible with water-based hydraulic fluids.
Is soluble and will be washed away eventually, to become part of the fluid.
Ideal for equipment installation and storage.

8. Fluorescene Dye
Can be added to the fluid to aid the detection of leaks
Added at ppm
Can be left in the system after addition
Enhanced leak detection with the aid of a UV (Black) light.

9. Oceanic LTF Oil based leak tracing fluid.
Used at 5% in existing BOP fluid.
Forms an intense white plume when mixed with seawater.
No special lighting required.
It is recommended to flush the system after use (See oil contamination).

10. Erifon Stack Glycol Compatible with Erifon Products
MEG with Corrosion Inhibitors.

11. Erifon Systems Cleaner
De-greaser
Sterilisation
Used to remove oil and grease from a system and kill fungus and bacteria.
Covered in a later section.

12. Erifon Pilot Line Fluid
Ready to use.
Made with pure water.
Correct quantity of Corrosion inhibitor, Lubricant and Biocide.
Correct Glycol content for use at -25°C.
To fit into new system designs by Shafer and Cameron.

13. Dilution Test Kit
Fill titration tube to 5ml line with diluted test fluid
Add indicator tablet
Fill syringe with Titrator Reagent B
Add Reagent B drop by drop until a pink coloration appears

14. Dilution Test Kit
Read the amount of Reagent B used to neutralise the fluid using the scale on the syringe
Locate this value on the Y axis of the dilution graph, read the corresponding X axis value to give the % dilution

15. Erifon HD603

16. Bacteriological Test Kit
Take an unused dipslide, unscrew cap and dip into sample or pour sample over both sides of the slide
Shake off excess and replace cap
Incubate for 48 hours at °C
Compare density of colonies to comparison chart

18. Refractometer
Calibrate the Refractometer by placing water on the prism, close the cover plate, ensuring there are no air bubbles in the trapped film of sample
Observe the Refractometer reading in the eyepiece. Adjust to zero using the adjustment screw

19. Refractometer Dry the prism and cover plate
Carefully apply a drop of sample to the prism and replace the cover plate
Observe the Refractometer reading in the eyepiece by measuring where the lower blue and upper white segments meet on the % BRIX scale in the centre of the view.
Use this reading to calculate dilution or glycol content

20. Refractometer
Multiply the Brix reading by 1.5 to obtain a glycol content reading.
Subtract the value of the Erifon concentrate.
This gives you the MEG content
