Yes, George, I'll jump on that one. Yes, it's a great point. I think in the early days, we identified sand intensity going up as a pretty significant trend. And obviously, that's driven the underlying growth in our business. But we continue to see more of it every day. The notion of the simu fracs that are going on today, the high grading of the frac crews that are operating today, we went from 350, 400 frac crews to 100 to 120 frac crews working today. So every crew is more efficient, better trained equipments being taken care of. So the pump hours per day just keep going up. And so where does that translate for our business is into throughput into our systems. So for the most part, we rent our equipment, and so our customers pay a fixed cost to run our equipment.
So every time they increase their throughput rate, they're actually paying less for our equipment on a dollar per ton equivalent basis. And so we did see roughly a 70% increase in the number of fully utilized systems deployed. But I'd say when we look at the actual total throughput that went through our systems, it's going to be higher in the quarter than the 70%. Roughly anywhere from, call it, 20% to 40% more loads or volumes of sand likely went through our systems in the quarter versus the second quarter. Clearly, in the second quarter, we saw people slow down their intensities and just tried to make it through. It was obviously a very difficult quarter for everyone. But we are seeing volumes go up on a daily basis in each of our systems.
And the big value that we provide is a large buffer directly at the blender in a very reliable system that's been tested and proven to work very well and a very simple process. Sand gets loaded into the silos and it's effectively gravity fed into the blender with the assistance of a couple of belts. And then further from that, as this intensity keeps going up, we've driven significant automation into the operation of the system. Historically, you would have somebody that physically operated the system, looking into the blender Hopper. And we've automated that through our AutoHopper system that we've talked about in the past. And what we're seeing with the AutoHopper system is a significant ramp-up in adoption among our clients. During these times, people are always looking for ways to save more money, reduce people on location, make it safer, et cetera.
And so we have customers running our system from the data van. So as we see trends going forward, we see fewer people and we see intensity continue to go up. And technologies like Solaris' AutoHopper and other things we're working on, I think will really prove to be valuable to both operators as well as pumpers.
