At this time (at my level of experience) it seems that the amp density issue is just as important in making hvcs as lvcs. With a hanging electrode, you would literally have to have to lower the electrode as the conductivity of the cs increases due to concentration and temp rise. I have done this with some success, but it is not very controllable when using just the end of a wire electrode for surface area. Can't really use a current limiting rout because the electrode end erodes too fast, and the water evaporates too fast to keep the same wetted surface area for long. That is basically why the commercial hvcs machines have their cs concentration limits.
Manually adjusting the electrode down during the run with a hand screw setup works well, but controlling the actual amp density is still a guessing game. A person who is willing to sit and watch every batch could probably get the feel of how to adjust the electrode and make higher ppm cs. However, by using more wetted surface area and a bigger transformer and actually being able to sink the electrode into the water, a person could control the process more easily. My suggestion for making high ppm hvcs is to have a large enough power supply to sink a known wetted area of silver into the water, and move the electrodes apart as the concentration rises to keep the same current density. It would require quite a power supply, and while I don't get too concerned with the commercial hvac generators as far as safety, the size of power supply needed to achieve the above system would be more than I would suggest someone tackle without some real high volt training and experience. But, with a way to calibrate the wetted surface area once in a while, my experimentation shows this will work very well. It will probably be my next cs generations system. Fast and furious hvcs and whatever ppm we find to be the system limits. As far as speeding up your current setup, you can heat water, but be warned that unless you sink the electrodes lower, and even into the water, you will make larger particles than you probably want. If you use hot water, it also changes the temp stratification that happens in the cs brew tank, and you will have to play with it to get the feel of how to operate. Batch tank size and shape mean a lot when making hvcs, and the temperature buildup at the surface of the water will be a different depth and temperature, changing the conductivity of the sol in the area of the electrodes. Stirring may be in order, but it really changes how your setup will run, and you will have to learn all over again what ppm to expect for a given run time. I spent a lot of time trying to speed up my CS Pro system. I did make some progress, but not a whole lot. The reason being, the faster you make cs, the faster the electrode erodes, the faster the water evaporates, the faster things get out of adjustment. To increase productivity really takes a re-engineering from scratch.
