This inflation system is more practical than the new CTIS as it gives the operator the choice of having separate tire pressure adjustment between the rear and front tires according to load distribution, great job Dan.
Thank you! The Mercedes Benz CTIS system for the Unimogs does allow the operator to choose the pressure of each axle (whether preset with the different modes or manually selecting the PSI that the operator wants in each axle). It just doesn’t allow individual tyres to have their own pressure (ie. left and right). But I can’t speak for all CTIS systems as some brands my have it as one pressure for both/all axles
Looks neat, very similar to MAN's optional inflation system. I would have thought you would install a gauge that doesn't require thinking about because as sure as eggs are eggs, at some point in time, a user is going to forget and open the valve quickly.
Thank you! The reason for using the gauge that we do is because if we fitted a gauge that shows 270PSI then we would only be working within a very small portion of the gauge once the trucks tanks are empty. Therefore it wouldn't be a very accurate reading when working between 20-80PSI and you would have to have great eyesight to be able to determine what PSI the tyres are actually at. For the very small percentage of time that the air tanks are being drained (approx. 5-15seconds) we think that the benefits of being able to see what PSI the tyres are actually at, outweighs the risk of customers spiking the gauge.
Do I understand it right that the speed with which the tire will be inflated depends on the compressor of the truck, which means that older truck with less good compressors will just last much longer to fill the tires again with air?
Yes, if the compressor is slow then it will take approx 15 minutes to fill all 4 tyres from 20PSI to 80PSI but a good compressor will take approx. 12 minutes.
@@unidanengineering Thanks a lot; How big / how heavy and how expensive would such a "good compressor" be? Why are you (apparently) so much faster than the STIS - System? Best regards, Andreas
@@apmimali4227 The Unidan RTIS system utilises the trucks on-board factory air compressor, I believe this is the difference between our system and the STIS system as that is an electric air compressor. Our RTIS system is designed specifically for the Mercedes-Benz Unimogs which all have on-board air systems.
Just a question and suggestion. Why don't you rather fit CTIS or design one that fits your needs? CTIS is much more convenient as far as I understand. I saw in a comment that you don't because you can't select different pressures for different tyres but can't you solve that problem with a vavle or something?
Retrofitting CTIS on the older Unimog through the axles is over $30,000 as you need CTIS compatible (more modern) axles as well as all the computer systems etc. There is also a company in Australia who we use, called Air CTI who do external CTIS which is approx. $14,000. It all comes down to needs, wants and budget. Our kit is less than $2000

@@unidanengineering Point taken, and sounds like the best compromise.
Who else wants to see a detailed factory walk round?
That's definitely been on our list of 'TO DO's' for a while now. Booking it in now! Stay tuned for later this month!

Thank you for the explanation, I now understand.
That explains my confusion
so what is the $2000 actually getting me ? a $5 gauge and 2 600mm length pvc pipes and a plastic shroud ?
Did you watch the video??
@unidanengineering3268 yeah and I'm still convinced that's it
