Lightbulb Waterless refrigerant

Hi guys over fifty! I was joking ...

As many of us know, our older RVs on steep climbs - especially in summer - tend to overheat.

Today I have an idea that could mitigate if not solve the problem, provided the radiator is clean and tidy. Have any of you ever tried to use "waterless refrigerant" instead of ordinary refrigerants?

The waterless refrigerant virtually eliminates overheating in petrol and diesel engines. It allows the motors to withstand higher temperatures without boiling and allows the cooling system to run at a very low or almost zero pressure. Thanks to the absence of water in the system, the engines with this liquid are free of electrolysis phenomena and work perfectly regardless of the type of driving and environmental conditions.

Cooling systems using this technology make use of non-water-based refrigerant with a high boiling point (over 180 C), keeping the refrigerant temperature considerably below the usual level. In contrast, traditional water-based cooling systems operate near the boiling point of the refrigerant. In traditional systems, the locally produced coolant vapor does not return to the liquid state, but forms an insulating barrier between the metal of the cooling sleeve and the coolant, causing heat points to form.

The water-free refrigerant also eliminates cavitation and erosion of the coating and freezes at temperatures below -40 C.

The only downside seems to be the cost, around $ 160 per 10 liters.

They are refrigerants that are usually used on high performance sports car engines.

Anyone have experiences about it?

Can our buses engines benefit from this product?

I think - with what they cost - it's worth spending more.

Keep in mind that these refrigerants are designed to last for a very very long time, so much that they are also considered "definitive liquids": put it once in the vehicle's life and that's it.
