The accelerated are similar but have a direct drive to the blower, which I do not like...
Joey,
Actually, we make systems with both types of drive methods.
Regardless of which we make, the blower turns at the same speed (as in the direct- coupled systems, like the Viper and Predator Unleashed), or 15% faster than (as in the belt- driven Dominator series systems) the engine RPM. We set maximum engine RPM's at 3,200 on our systems, unless the customer requests otherwise. So, on the belt- driven systems, blowers driven at 15% over engine RPM result in just a tad over 3,600 (3,680 RPM).
We don't under- drive blowers on any of our systems. And we use large, 7" pulleys to drive the blowers. Using large pulleys reduces the amount of belt tension necessary to maintain good traction. And reduced tension translates into reduced bearing and seal wear on engine and blower seals.
The internal water tank located on the system frame is positioned closely to the engine exhaust. As a result, the ambient heat transferred into the water at that point is "free heat". And that heat results in lower propane consumption / higher output temperature capability at a given heater BTU rating.
Dominators deliver 2,000 PSI, the heaters used handle 10,000 PSI and maintain in excess of 230 degrees at the wand through a #6 jet, at 600 PSI. They can maintain a constant temperature of 200 degrees through a tile "spinner" tool at 1,500 PSI. So they are very well- suited for demanding jobs like restaurants and tile and grout cleaning. And they are mounted on the system frame in order to keep system footprint as small as possible (yet at the same time, un-cluttered).
Dominator 3047's can run two wands simultaneously and maintain those heat levels.
And all of our recovery tanks are made of 3/16" aluminum.
Our systems typically require about 3/4 as much space as similar systems as well.
Vipers use Little Giant heaters (and the same engine exhaust/ water tank positioning configuration that Dominators do). So they're more of a direct- comparison to systems that use Little Giants. They feature 20 HP Kohler Command Pro engines, electronic ignition on the Little Giants, true usable capacity 70 gal. recovery tanks and get it all onto a very uncluttered footprint size of 21" Wide by 62" Long, which is about half the physical size of comparable systems.
Although they are direct- coupled, Vipers feature a couple of unique drive enhancements designed to make coupler replacement virtually unnecessary... but at the same time, easy to do.
1.) The Blower Leveling Plate allows the height and angle of the blower in relation to the engine to literally be "dialed in", via a large adjustment stud on each of it's 4 corners. Locking nuts secure it once it's positioned as desired.
2.) The Engine Slide Plate allows the engine to be de- coupled from the blower via sliding it forward on the system frame. Guides on the side of the frame maintain alignment both while the plate is secured and while it's being moved back and forth for coupler replacement. It also has 4 locking bolts to keep it secure while the system is in operation.
