  • What is an antifreeze agent?
  • An antifreeze is defined as an additive that, when added to a water-based fluid, will reduce the freezing point of the mixture. Antifreeze agents are used in mechanical equipment in environments below the freezing point to prevent the freezing of heat transfer fluids.
  • What are EG-based antifreeze formulations?
  • EG-based antifreeze formulations may contain small amounts of other glycols such as diethylene glycol or triethylene glycol. Propylene-based glycols such as propylene glycol and propylene glycol ethers have limited use, especially in areas in which regulations about human toxicity apply.
  • Which antifreeze agents are used in heat transfer liquids?
  • The classic antifreeze agents in heat transfer liquids are brine solutions and alcohols. 14.3.1. Brines Of the commonly used antifreeze agents, brines are the most corrosive to metals of the engines and exhibit scale deposition characteristics that are highly restrictive to heat transfer.
  • How many types of antifreeze chemicals are there?
  • Inspection of Table 14.1 shows that there are two different types of antifreeze chemicals, that is, liquids that are miscible over the full range of concentration with water and salts, often salts which are soluble only to a certain amount. In the case of liquids, a mixture of 50% with water is given.
