DOWFROST HD 40% inhibited propylene glycol offers effective heat transfer over a wide temperature range: from -6 °F to 325 °F.

Dowtherm Q liquid phase heat transfer fluid is designed for use as an alternative to hot oils from -30 °F to 625 °F.

DOWTHERM J is a specially engineered mixture of isomers of an alkylated aromatic designed for low-temperature heat transfer systems from -110 °F to 600 °F.

DOWTHERM RP is a liquid phase heat transfer fluid that may be utilized in heat transfer systems operating between -4 °F and 660 °F.

UCARTHERM Heat Transfer Fluid is a biodegradable ethylene glycol based fluid that provide outstanding freeze and burst protection from -60 °F to 275 °F.

DOWTHERM 4000 inhibited ethylene glycol (EG) is comprised of about 92% EG and 8% corrosion inhibitors and has a bright fluorescent orange color. The lower EG content allows for a higher concentration of corrosion inhibitors which in turn means DOWTHERM 4000 is capable of operating at higher temperatures than DOWTHERM SR1 i.e. from -60 °F to 350 °F. This makes DOWTHERM 4000 a higher end, niche type product which is also capable of providing freeze protection down to -60 °F.
