What solution is used in the chiller?

• A. Pure Ethaline
• B. A mixture of Ethaline glycol and water
• C. Ethylene glycol and water
• D. Propylene glycol and water

Answer: (B)

A glycol–water coolant is used in chillers to provide antifreeze protection while maintaining effective heat transfer. Ethaline is a brand of glycol-based coolant, and mixing it with water creates a solution whose freezing point is depressed to prevent the circulating fluid from freezing in cold conditions and to protect the system’s metals and seals with its inhibitors. The right balance comes from this glycol–water mixture, which offers the needed combination of low freezing point, suitable viscosity, and corrosion protection. Using pure glycol would be unnecessarily viscous and harder to pump, and while ethylene glycol–water mixtures are common, the specific formulation referenced here is Ethaline glycol with water, which aligns with typical chiller operating guidelines. A propylene glycol–water mixture is another alternative in some systems, but the given context points to Ethaline glycol and water as the standard coolant.
