What is a Heat Transfer Fluid?
A heat transfer fluid (HTF) is a liquid or a gas that transports heat from one component to another component in any process requiring heating or cooling or simply to maintain a constant temperature. The desirable attributes of a heat transfer fluid are non- or low toxicity (sometimes food grade or food safe), low viscosity at low temperatures, high specific heat and thermal conductivity, environmentally friendly, high flash point (or non-flammable/non-combustible in some cases) and economical.
What are some of the processes that require a heat transfer fluid?
Here are some examples of processes requiring an HTF are: cooling of a reactor with an exothermic reaction, maintaining a very low temperature climactic chamber or wind tunnel, utilizing solar energy to make hot water, cooling an engine block, maintaining the ice temperature in an ice rink, cold storage and cooling high power electronics.
Why there are so many different HTFs available?
In general, HTFs can be classified into (1) low temperature, (2) medium temperature (glycols) and (3) high temperature fluids. Low temperature fluids are normally used below 32ºF (0ºC) down to about -148ºF (-100ºC). The chemistries that are used as low temperature heat transfer fluids are salt brines, hydrocarbons and silicone oils. Glycols such as propylene glycol (PG), ethylene glycol (EG) and 1,3 propanediol (Bioglycol) are used for freeze protection below 32ºF and can be used up to 350ºF with a proper additive package. High temperature fluids are normally used above 350ºF up to 662ºF (350ºC).
