Babban amfani da ethylene glycol shine azaman maganin daskarewa a cikin na'urar sanyaya alal misali, motoci da tsarin sanyaya iska waɗanda ko dai suna sanya injin sanyi ko masu sarrafa iska a waje ko kuma dole ne suyi sanyi ƙasa da sanyin zafin ruwa. A cikin tsarin dumama / sanyaya ƙasa, ethylene glycol shine ruwan da ke jigilar zafi ta hanyar amfani da famfo mai zafi na geothermal. Ethylene glycol ko dai yana samun makamashi daga tushen (tafki, teku, rijiyar ruwa) ko kuma ya watsar da zafi zuwa ga nutsewa, dangane da ko ana amfani da tsarin don dumama ko sanyaya.
Pure ethylene glycol yana da takamaiman ƙarfin zafi kusan rabin na ruwa. Don haka, yayin samar da kariyar daskarewa da ƙarar wurin tafasa, ethylene glycol yana rage takamaiman ƙarfin zafi na gaurayawan ruwa dangane da ruwa mai tsafta. A 1: 1 Mix ta taro yana da takamaiman ƙarfin zafi na kusan 3140 J / (kg · ° C) (0.75 BTU / (lb · ° F)), kashi uku cikin huɗu na ruwa mai tsafta, don haka yana buƙatar ƙarin ƙimar kwarara a cikin guda- tsarin kwatanta da ruwa.
