Woohoo! My current van was built 9 years ago, 12v a/c was rather slim then, got an Indel Cube, maybe 3000btu, and... its not done well. Last year we finished her new van with a 120v roof unit (RecPro?), rated 9k, and... its ok. I'll be building my second van next spring and looking at 48v units; interested in split setup but dunno if the cost is worth it over roof mount.
Great video! I personally have a 33ft fifth wheel, but being able to have supplemental cooling for down the road is a nice option. We have the majority of the RV 48v though, I wish they started designing more versatile voltages. But for a van, 12v is really the way to go for a simple and robust system!
@@stinson87 agreed! There really are pros and cons to any system. That’s why we ask specific lifestyle questions when helping customers find the right products for them
Great and concise information on the available 12 V systems. I’m biased, but after having purchased and using the Dometic, Velit and Nomadic X2 (not X3), I can confidently say the Dometic outperforms the other mentioned units. My second favorite is the Velit and it is close. Like the rep of Dometic more!
I am comparing the dometic and vellit for my service rig, I had not heard of the other brands but it's surprising the most expensive unit was the word performing
@@blackfootmechanical5413 it was a surprise to us, too, but it’s just further confirmation that we have to do the extra work to verify! We hope this video is helpful in your decision making process. If you have any questions about the Dometic RTX or Velit unit, please reach out to us. We have in-house tech support when you need us.
Looking at ur run time chart and it says 14 hours on 600amp hours. There’s no way in gods green earth u can run 14 hours on those batteries. Idkn maybe I’m missing something but I only get about 4.5 hours on a cool day
@@dishcleaner2 decidedly, when it’s on constant high output, yes, it will pull more power as it has twice the cooling capacity, but power draw is all relative in many scenarios. When an a/c unit is designed properly, it will scale up and down based on the cooling capacity necessary to maintain your set temperature. So, where the RTX may be working harder to maintain, the new 48V Freshjet would be able to scale down, thus reducing the power draw
@@rackupgo thanks for the info. I'll keep my eye out for it. It makes sense theoretically, but I'd still like to see an in depth video testing out its efficiency in comparison to other models.
@@ryanrodriguez70 we did. Here’s the link for that one: rackupgo.com/blogs/buying-guides/optimizing-comfort-and-efficiency-a-comparative-analysis-of-gree-eco-cool-vs-nomadic-x3-rooftop-air-conditioners
Voltage alone doesn't necessarily have an impact on performance unless the components also increase in capacity. Higher voltage units can take advantage of greater available power and build in higher capacity components to achieve more cooling power. Efficiency (how well the unit converts the power into cooling power) will ultimately depend on the components used and how well the system is designed. The benefit of a higher voltage unit is that the wire gauge is able to be decreased. This allows for easier running of the wire, higher voltage units have a lower current which leads to less heat in the wire, and less weight as a result of the smaller gauge wire.
