Is glycol bad for boilers?
Glycol Characteristics A glycol concentration lower than 50% avoids overtaxing the performance of the system’s boilers and pumps while eliminating the risk of damage occurring in low-temperature climates.
At what temperature does glycol freeze?
-12.9 °C
Ethylene glycol/Melting point
Should I put antifreeze in my boiler?
Do not use automotive antifreeze in heating boiler systems. Some of these can clog the boiler heat exchanger.

What are the side effects of propylene glycol?
Summary At toxic levels, propylene glycol has been found to cause seizures and severe neurological symptoms. There have also been cases of nausea, vertigo and strange sensations.
What happens when you add glycol to a HVAC system?
Solutions containing glycol may affect the various types of metals and plastics commonly used in HVAC systems, and corrosion is possible in some metals. Water quality also plays a factor in the performance of the solution.
What are the problems with a glycol dehydration system?
If you operate a glycol dehydration system, short of something spewing, leaking or catching on fire, the most common and troublesome problems come in the form of a symptom that you have to find a cause for. Accidental discharge, leaks, and fires are obvious but the possible causes of poor dew points and unusual glycol loss are not.
What are the pros and cons of ethylene glycol?
Ethylene glycol has a high boiling point, low freezing point, and is stable over a wide range of temperatures. It also has a low viscosity, so less power is required for recirculating pumps.
Why is ethylene glycol used as an antifreeze?
Ethylene glycol is the most common antifreeze fluid for standard heating and cooling applications because of its outstanding heat transfer efficiency. Ethylene glycol has a high boiling point, low freezing point, and is stable over a wide range of temperatures. It also has a low viscosity, so less power is required for recirculating pumps.
What causes a reboiler to be too hot?
Replace the tower packings in the still column, if fouled or powdered. If the outlet gas temperature from the absorber exceeds the inlet gas temperature by more than 20 to 30°F, the lean glycol entering the top of the absorber may be too hot. This could indicate a heat exchanger problem or an excessive glycol circulation rate.
What happens if there is too much glycol in a chiller?
*The proper propylene glycol to water ratio mixture is very important in your chiller system. Too little glycol can lead to a costly freeze up. Too much glycol inhibits system efficiency. OK, I’VE DETERMINED WHAT MY PERCENTAGE SHOULD BE, HOW DO I FIGURE OUT HOW MUCH GLYCOL I’LL NEED FOR MY SYSTEM?
What should the reboiler temperature be for lean glycol?
The reboiler temperature for the TEG regenerator is typically limited to about 400°F to minimize glycol degradation. Consequently, this temperature limits the lean glycol concentration to between 98.5% and 98.9%. Some operators limit the reboiler temperature to between 370°F and 390°F.
Why is there so much glycol in a refrigerant system?
Many brewery operators don’t understand why so much glycol is needed in their chiller system. They assume that if the chiller system is at +27 °F glycol, the freezing point of the solution only needs to be below +27 °F. But you must keep in mind the temperature of the refrigerant will be 10 – 15 °F below the temperature of the glycol solution.
