Steam for heating heat transfer oil
Thread Content
This post was last edited by WoAiMaoMaoRan on 2015-12-23 at 08:07. Are there any systems that use thermal oil for heating? What’s the cycle duration? How often should the oil be replaced—every few years? The heating temperature is around 200 degrees. Is it more cost-effective to use steam or thermal oil?
Use heat transfer oil at 200 degrees. I’ve seen ones that haven’t had their oil changed in 5 years
Heat transfer oil can last for at least 3 years, and there is no requirement for mandatory replacement; it can still be used effectively after being filtered
Heat transfer oil should first be used in a closed system to reduce its oxidation. The amount of heat transfer oil used in our factory is so large that replacing it would incur high costs; therefore, it isn’t replaced every few years – it hasn’t been replaced in a long time
In the long run, it is definitely more cost-effective to use heat transfer oil, as different models and types of oil are available, so there is no way to make a comparison. The most important thing is regular use and testing. Used properly, it can last 3-5 years without any problem. The system should be kept away from prolonged contact with moisture, otherwise it is prone to oxidation and cracking. The usage cycle naturally decreases. It is possible to check the condition of the oil every six months to one year.
At over 200 degrees, for a closed system with a complete nitrogen seal, using 300# oil, the lifespan is 5-8 years
Today’s systems are all semi-closed type; the temperature of the sump should not exceed 60 degrees. Under normal flow conditions, the 320 model of heat transfer oil can last for 6 to 8 years with no problems. One is the quality issue of the oil, and the other is the customer’s own usage. Our company enters into quality assurance contracts with customers for all our heat transfer oils. We can provide free training on how to use it.
Well, we are still considering it right now. I’ll consult you again if needed!
If heat transfer oil is not handled properly, it tends to coking; in our unit, we generally replenish it at regular intervals； The cost of heat transfer oil is too high; it’s not worthwhile to replace it entirely
