What Brix should my glycol be?
What Brix should my glycol be?
24.75 brix
What is the Proper Glycol to Water Percentage or Mixture? G&D Chillers recommends a 35% Inhibited Propylene Glycol to 65% water (24.75 brix).
How do you test glycol in water?
Testing for antifreeze (ethylene glycol) in water is quick and easy. Simply add your sample to the fill line, break the three ampules in order and wait 30 seconds for color to form. If a dark blue color forms in the pouch there is ethylene glycol present in the sample.
How do you calculate glycol concentration?
Typically an annual check-up will include verification of the glycol concentration with a refractometer, and a check of the glycol PH level using litmus test strips. Glycol that has gone bad typically will have a low PH level, which if left unchecked, will start to corrode the metal components in the system.
How do you calibrate a refractometer for glycol?
To calibrate open the daylight plate (numbered 1), place 2 – 3 drops of distilled water onto the plate and close. Wait for approximately 30 seconds and twist the calibration screw (numbered 2) until the light/dark boundary coincides with the zero line.
What is the ratio of water to glycol?
Percentage Glycol in Chilled Water Systems For many chiller types, ethylene glycol is mixed with water at a ratio of 60/40. This higher percentage of glycol boosts the mixture’s antifreeze properties significantly. This is useful in cases where rapid cooling is required.
How does a glycol refractometer work?
Refractometers measure the glycol concentration and gives the antifreeze freezing point. This instrument requires only a few drops of fluid for glycol testing and requires no adjustment for fluid temperature.
What is a glycol refractometer?
Glycol Refractometer is used to determine the freeze points of Propylene Glycol and Ethylene Glycol fluid solutions.
How much glycol is needed?
How much glycol do I need in my system?
| Outdoor Temperature | Ethylene % of Glycol Required | |
|---|---|---|
| -5 | 20 | 18% |
| -12 | 10 | 24% |
| -18 | 0 | 32% |
| -23 | -10 | 39% |
How much glycol do I need to add?
How do you read a refractometer for antifreeze?
Read the scale value at the intersection of the dark and light portions, at the point where they meet on the scale. Use a screwdriver to rotate the adjustment screw calibrate the refractometer, adjusting as needed until the light/dark boundary (shadow line) lines up with the zero line.
What does a refractometer measure in coolant?
Refractometers are instruments used to obtain a °Brix reading, which measures the oil content present in a coolant mixture. Additionally, each coolant refracts light differently and therefore has its own specific multiplier, called a refractometer factor.
