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).
Dynalene heat transfer fluids cover a very wide range of usage temperature, from as low as -112°C (-170°F) to as high as 565°C (1050°F). Dynalene’s customers range from Fortune 500 companies building large industrial complexes to small businesses servicing residential HVAC systems. Dynalene also provides laboratory testing services including heat transfer fluids and glycol testing, thermo-physical properties and quality control.
Ready for winter? Check the freezing point and the burst point of your glycol
When using glycol/water mixtures in your heat transfer fluid system, it is important to consider how cold the fluid will get, but it is also equally important to consider how the fluid will be used at that temperature. Will the fluid be stagnant or will it be circulated? Is the glycol for winterization? These questions ultimately affect the mixture ratio of the glycol. For example, if a coolant loop or system is being winterized and temperatures will fall down to -10°F at the lowest, a mixture of 30% propylene glycol to 70% water will be enough to protect the system. 30% propylene glycol has a freeze point of 8°F but the burst point is -18°F. This system will be protected but the coolant will be slushy. By definition, freezing point is the temperature where ice crystals begin to form. The fluid will become slushy but will not expand. The burst point of a fluid is the temperature where the fluid will freeze solid, expand, and break pipes or damage other parts of the equipment.
