Sometimes, people confuse propylene glycol with ethylene glycol. Their chemical structures are similar, and both are used in antifreeze, but they’re not the same. In antifreeze, propylene glycol lowers the freezing point of water, which keeps the antifreeze product liquid. It replaces ethylene gl...

DesignPerformanceCoolantsEthyleneCooling systemsAn experimental program has been conducted to evaluate the thermal performance, the relationship between surface heat flux and surface temperature, of two engine coolants at off-design operating conditions. These conditions could be caused by high ambient ...
A performance review is presented for ethylene glycol and propylene glycol coolants in a heavy duty fleet test. Vehicle maintenance and testing specifications are highlighted. Aspects of regular filter change intervals and glycol segregation are underlined. The effect of glycol type on system hardware ...
A non-aqueous, reduced toxicity diol based heat transfer fluid is provided comprised of at least one diol that acts as an antidote for ethylene glycol poisoning, such as for example propylene glycol. The heat transfer fluid may also include corrosion inhibitors that are soluble in the diols ...
