Maintaining Your Heat Transfer Fluid

in Fluid

Performing the proper maintenance on your heat transfer fluid and the system can help to extend the life. It is like with anything else it has to be checked on and serviced to keep everything running smoothly. Doing regular maintenance helps to reduce down time and it also helps to reduce your overall heat transfer fluid costs. Different heat transfer fluids have different optimal operating temperatures. The aromatics, petroleum-based fluids, polyglycols and silicones operate best at temperatures of 150 degrees Fahrenheit to 750 degrees Fahrenheit.

The first step you will need to do to maintain your heat transfer fluid is to take a fluid sample at a predetermined time interval. Depending on the unit is how often you check the fluid and also the past experience of the unit. If you are not sure then it is best to just check it quarterly. If it is your first time and you not quite sure on how often you should check once you get the fluid tested then you will get a good idea of how often it needs to be done. A good thing to do is use the first sample as your base. You should take the samples from the discharge side of the main heat transfer system pump or from any main line flowing in the system. You take it from there because it ensures a sample representative of the fluid in the system. Make sure you allow the fluid to cool. The best arrangement is a sampling bomb because it allows sample flow through, sample isolation and also cooling. This kind of procedure prevents the accumulation of solids in stagnant sample lines.

Then once you have the fluid sample taken then you send it to the company that supplies the heat transfer fluid. Most places offer this type of service for free. So when you purchase your fluid ask if they do offer this kind of service. Once you get the results back then you will have a good idea of where to go from there. The fluid may be fine or it may need some changes. The company will give you some ideas of what to do next if the results don't come back ok. System problems occurring after a successful startup, when the heat transfer fluid is within the used fluid limits, are more commonly operational in nature and are not related to the fluid.
