John 3:16 "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life."

Industrial Antifreeze

Industrial Antifreeze/Heat Transfer Fluid (HTF) is a vital component in the operation of many types of machinery, including heavy equipment, vehicles, and industrial processes. These machines generate heat and antifreeze helps to dissipate that heat and prevent damage to the engine or other parts. But with so many types of industrial antifreeze on the market, how can you choose the best one for your needs?

The best industrial antifreeze will depend on several factors, including the type of machinery being used, the temperature range in which it will operate, and the overall conditions of the environment. Some key considerations when choosing an industrial antifreeze include:

  1. Ethylene Glycol vs. Propylene Glycol:  These are the two most common types of antifreeze and each has its own advantages and disadvantages. Ethylene glycol is toxic to humans and animals and is hazardous.  It is, however, still the most common because it is cheaper and offers lower viscosity (it’s thinner) at lower temperatures.  Propylene glycol is less toxic (still toxic to cats) and therefore safer for workers and the environment than the Ethylene Glycol.  It is slightly more viscous at lower temperatures.
  2. Glycerin Antifreeze:  Glycerin offers the safest alternative to glycols.  It is non-toxic and safe for the environment, however, it can only offer freeze points down to @ -50F and is more viscous than the glycols at the lower temperatures.
  3. Corrosion Protection: Industrial machinery is often made from a variety of materials and the antifreeze needs to protect against corrosion and other types of damage. Some offer very old inhibitor technology such as nitrites, molybdates, amines and some, like Orison’s PG and Glycerin antifreeze/HTF’s, offer new organic acid technologies and food grade inhibitors.  Look for an antifreeze that has been specifically formulated or tested to protect against the materials used in your machinery / application.
  4. Temperature Range:  Make sure that the antifreeze/HTF you choose can handle the temperature extremes in your environment.
