DELO Chloride test
What temperature should the sample be before testing?
100 degrees
T/F. Is a Brix refractometer used for a concentration test?
True
What is the main purpose for jacket water?
Accepts heat from hot areas of an engine and rejects heat at a heat exchanger
When handling DELO xli what PPE shall be used?
Face shield, rubber gloves and apron
T/F. Brix refractometer is how we test for chloride.
False
If the Brix reads 0% when tilting it to a strong source of light would a calibration be needed?
No
What are effects of untreated jacket water?
Scale, corrosion and cavitation corrosion
After adding mixture to the engine or system, what needs to be done as soon as possible and when?
Recirculation within 24 hours
What is the max PPM that is allowed for a Chloride test?
100 PPM
When closing the window on the Brix refractometer, what should you ensure?
Ensure you are closing it slowly to avoid loss of sample and bubbles on window
What does potable water contain that makes it not meet requirements for jacket water fill water?
Contains high levels of dissolved hardness ( calcium and magnesium)
What do we use onboard that ensures we can use shipboard water for fill water?
Demineralizer. Prior to use the water should be tested for conductivity and silica. Conductivity 150umho/cm max. Silica 2ppm max
Before using a Quantab strip, what are you ensuring on the bottle before testing?
The expiration date has not passed
What percentage is a SAT sample when testing for concentration?
6-10%. Aim for 8%
When should samples be tested after sampling?
1 hour after sampling
What do you use for testing PH?
ph test strips
What apparatus are used to test for Chloride?
Beaker(2), graduated cylinder (10ml), Quantab chloride strips and the calibration chart provided on bottle of quantabs
What apparatus are used to conduct a concentration test?
Brix refractometer, plastic dropper, and lint free cloth.
Engine jacket water samples for all treatments shall be obtained and tested when?
Within 24 hours after freshly filling and treating(FF)
Within 24 hours after adding water to the cooling system(AWA)
Within 24 hours after adding inhibitor to the cooling system(ACA)
At least monthly(RTE)
IAW PMS (PMS)
For fresh fill, how many gallons of DELO XLI is needed for every 100 gallons of cooling capacity?
8 gallons for every 100 gallons
