Ethylene Glycol vs. Propylene Glycol vs. Food Grade Glycol

Jun 17, 2015Glycols are normally used for industrial HVAC, Process cooling/heating, and antifreeze. There are two main types of glycols, ethylene glycol and propylene glycol with propylene glycol available in industrial and food grades. Ethylene glycol is commonly used in applications where efficiency is important and there is no human or animal contact due to the toxicity of the ethylene glycol

Ethylene Glycol

In geothermal heating/cooling systems, ethylene glycol is the fluid that transports heat through the use of a geothermal heat pump. The ethylene glycol either gains energy from the source, or dissipates heat to the source, depending if the system is being used for heating or cooling. Due to its low freezing point, ethylene glycol resists freezing.

Selecting the Proper Glycol Concentration for Closed

Aug 14, 2016There are two basic types of glycol protection available for your closed-loop HVAC system: "burst protection" and "freeze protection.". Burst protection is sufficient if the system will remain dormant or inactive when the temperature drops below freezing and there is adequate space to accommodate the expansion of an ice/slush mixture.

Antifreeze

When ethylene glycol is used in a system, it may become oxidized to five organic acids (formic, oxalic, glycolic, glyoxalic and acetic acid). Inhibited ethylene glycol antifreeze mixes are available, with additives that buffer the pH and reserve alkalinity of the solution to prevent oxidation of ethylene glycol and formation of these acids. Nitrites, silicates, borates and azoles may also be used to prevent corrosive

The pros and cons of adding glycol to HVAC systems using

Mar 19, 2014Ethylene 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.

Can I mix ethylene glycol and propylene glycol?

Glycol is added to water systems because it is effective in reducing the freezing point and minimizing the risk that pipes will freeze and be damaged. Yes, glycol does affect the efficiency of heating systems because it does not transfer heat as well as plain water.

May 21, 2009Besides cooling system breakdown, biological fouling also occurs. Once bacterial slime starts the corrosion rate of the system increases. In systems where a glycol solution is maintained on a continuous basis, regular monitoring of freeze protection, pH, specific gravity, inhibitor level, color and biological contamination should be checked routinely.

A History of Automotive Coolants

A History of Automotive Coolants. Liquid coolants (usually a half and half mixture of water and ethylene glycol (EG) based antifreeze) are used to manage heat in automotive internal combustion engines.

How an engine cooling system works

In a cooling system of this type there is a continual slight loss of coolant if the engine runs very hot. The system needs topping up from time to time. The system needs topping up from time to time. Later cars have a sealed system in which any overflow goes into an expansion tank, from which it is sucked back into the engine when the remaining liquid cools.
