When buying a glycol coolant, the consumer wants to be sure that the product will retain its characteristics for a long time. Which one exactly? How long can the coolant work? When will it have to be changed?
At different times, in relation to different products, there were quite a few different terms: expiration date, service life, service life, warranty period ...
Regarding the coolant, the domestic manufacturer is obliged to establish a "warranty storage period". This means that the preservation of the quality of the coolant during its storage is guaranteed, provided that certain rules for such storage are observed.
The manufacturer is not obliged to set a guaranteed service life. And that's why.
The quality of the coolant in the circuit is affected by a huge number of external factors. Here are just some of them and possible consequences:
| factor | possible consequences |
|---|---|
| not flushed contour before filling | contamination of the coolant |
| rinse water not completely drained | dilution of the coolant, increasing the temperature of crystallization |
| circuit depressurization | contamination of the coolant |
| heat carrier overheating | thermal decomposition of the coolant |
Will the coolant be able to maintain its parameters if similar situations occur with it?
Of course, a quality heat carrier contains substances (functional additives) that are designed to combat "bad" situations However, as a result of such a struggle, the composition of the coolant will deteriorate. No expert can predict what situations will occur and how much time will pass before the parameters of the coolant go beyond the norm.
And if a label shows the phrase: "Warranty period of operation – 5 years», think about it, the manufacturer is really ready to guarantee an unchanged composition and the properties of the coolant when an unscrupulous installer dilutes it with tap water?
Thus, the duration of operation of the coolant depends on the conditions of this operation.
Good news: if you approach operation correctly (absence of contamination, stability of modes, tightness of the circuit, professionalism of the staff), the coolant can work for decades. We have a product manufactured in 2008 and poured into the system at the same time. We check its quality every six months. The parameters are practically unchanged..( Tepro-P )
The heat carrier becomes unusable for further operation not after the end of a certain period, but if its parameters do not meet the specified standards. But even this is not a verdict. In many cases, its composition can be adjusted ( Correction. Restoration of properties < u>) and continue to work successfully.
