Who makes great Steam pressure washers? Here are some requirements: Prefer total portability so that means oil/diesel fired boiler and gas or diesel internal combustion engine to power the pump. As high a Steam temp and Temp rise as possible. The higher the PSI and GPM the better. Now Karcher and Steam Jenny and a few others I can't recall at the moment have max steam temp that goes up to around 320-330 F. Some other Mfgs only go up to 280ish F. I have a few questions: Would an IC engine powered Steam/Hot pressure washer be as good if not better than a 220-240 volt single phase electric powered unit (electric pump, not boiler)? What exactly is Wet Steam? Can a skid mounted unit be made portable simply by adding wheels? What brand/s do you'll prefer/like? How much lower is the temp at the tip of the wand than the temp in the boiler?
The better high temp, 325 degree machines are from Steam Jenny and Sioux. If you go to either website that have a page that gives a good explanation of everything. In a normal steam cleaner you are not going to get high pressure or volume, they generally run about 100 to 200 psi and 70 to 150 gph. With a combination unit (steam cleaner, hot water pressure washer) you can kind of get both, low pressure steam and high pressure high volume hot water. Steam will get to 325 and hot water around 200 degrees or so. As for engine or electric driven pump, a engine driven pump will have more volume and pressure than a electric one. Unless you go to a very expensive 5 horse and up 230 to 460 volt 3 phase unit.
Can these pressure washers , like the Jenny, provide super heated water? Saturated water, i.e. Steam+Water mix , so we get high temp steam and force of liquid water ? How much does the temp drop at the tip? What is the preferred brand of portable Steam pressure washers in the construction industry? I found this past auction for a Mining Equip. company that has a Jenny Steam pressure washer, so was wondering if a specific brand was more prominent in the mining and construction field. http://www.hunyady.com/auctions/pdf/GODIN 11X17F.pdf
