“At their simplest, they rely on a coolant that absorbs and dissipates heat from the house.”

“After being used as a coolant, the water is returned to the canal about 10 degrees warmer.”

“You should also check the level, condition and concentration of the coolant every so often.”

“Two of the coolants extensively used are ethylene glycol and propylene glycol.”

“To beat the heat, fluid-flow systems circulate coolants through the machines.”

“Pipes were split open, releasing coolants that froze nearby structures with a coating of white, sparkling frost.”
