Are you saying the x-Drive includes batteries between the generator and motor controller? I hadn't heard that. I doubt it.batteries buffer the transfer and ensure constant power.

to relieve some or all of the loadPlus for that much power you would need 220-240v anyhow.
Probably not but it would be nice to be able to use it as a backup generator if your power went outNo that would be a nightmare.

Lemme guess - you're the exclusive distributor for replacement batteries.That is the way I advised them to do it, and that is the way they did it.
From now on I hope you have learned your lesson and won't doubt me again. Find someone to give you a hug.
Ps I dropped the mic!
"If you have to ask, you can't afford it."
Let me say I don't particularly "like" the performance of the regular CDs.
With that said this xdrive is defiantly a step up and in the right direction. The suction was strong and didn't "bog down" under continuous vac at 14" for even minutes.
Bigger blower is much better and with the door closed and on boost the truck is relatively very quiet.
I'm telling you, if it is as reliable as the regular CDs's this thing will be a home run for hydramaster.
Also think I saw somewhere it has a 3 year warranty, don't quote me but I do think I saw that so where on their advertising.
buildup during operation would overheat the blower ( have you ever felt your blower after 6 hrs of running (this could be mitigated by a liquid cooled blower)) and in cool climates you would have to consider freezing while drivingAnyone tried mounting the blower and pump in the engine compartment? Would probably require a bulge in the hood and/or other body modification, but would be simpler mechanically and probably less expensive.
Thanks for the feedback.
Here is some information from our Engineering team addressing some of the questions raised:
- Fuel efficiency numbers. Fuel consumption is very similar to a CDS. It ranges from 1.48gph in an economy setting to 1.95 gph in the boost setting.
- Engine rpm 1500 vs 2000. We have tested various different engine rpms. The 1500-1700 rpm range does not spin the generator fast enough to produce enough power for ‘full load’ operation, which is considered to be: 3000rpm blower speed, 1200psi pump pressure, and 14”Hg of vacuum.
- Voltage and frequency changes from generator affecting motor performance. Both the generator and motor are controlled independently so any changes in generator voltage or frequency do not effect motor performance.
- Motor efficiency numbers. Both the generator and motor run at 96% electrical efficiency.
Cool! I saw the fluid connections on the motor and was going to ask if it was water-cooled, but then it was explained that both the motor and generator are.
So after seeing the video I'm guessing a DC generator and a PMAC motor with controller.
Aluminum corrodes very slowly. The aluminum frame and tanks will outlast the vehicle they are installed in.Thanks Hydramaster and MB for the footage.
Looks like a great unit that's addressing an industry issue for direct drives. The carbon monoxide emissions are also a huge purchase factor to us. (xDRIVE are much less than slide in's I imagine.)
The only major concern I foresee is material used for production. The aluminum on HM seems to corrode very easily.
