Which outcome occurs when ethylene glycol concentration falls too low in a chiller unit's closed-loop system subjected to sub-zero temperatures?

💡 Explanation

Ice crystal formation occurs because insufficient ethylene glycol lowers the *freezing point depression* mechanism, allowing water content to freeze and expand, therefore causing blockages and potential damage, rather than preventing it as a higher concentration would.
