Besides the thermostatic control of the water temperature, propane systems are extremely versatile and simple to operate and maintain, and with built-in emergency gas shutoff and venting, can be operated with a high degree of dependabilityand safety. Rather than use two floor wands, many cleaners prefer to take advantage of the “dual-wand” configured system by having one technician cleaning with a floor wand and another using a furniture or detail tool at the same time, achieving optimum performance at around 380cfm. This is done by adjusting the water flow through the inner heat exchange tube.” The real advantage to the simpler slide-in systems is that they are just as powerful, yet much easier and cheaper to maintain with less down time, since much of the maintenance can be done by the operator. After all, even if you could, you wouldn’t wash your clothes inboiling water because over time it would damage the material, just as it will damage carpet fibers, backing and glue. 15Hg stands for 15 inches of mercury.2. Most truck mount systems today can produce extreme temperatures or steam if you turn the heat up higher than it should be. Pressurized water from the system pump flows through the hot water heater and is delivered to the wand for cleaning.
If you set your system too low below 15Hg you may not have enough lift for extraction, set it too high above 15Hg and you run the risk of doing damage to your system. (Optimum Performance: 600psi)Water pressure forces hot water or hot water and cleaning agent into, over or through the carpet. If you know what the optimum performance is that you “have to have” to do the work you want to do, then use that knowledge to obtain an economical and easily maintained system that is going to be of service to you for years, making you money, rather than one that you spend years of money servicing. The only negative in comparison to heat exchange is that you have to purchase propane gas to run the heating system. . However there are some disadvantages. If you are cleaning residential homes, moving from room to room, moving furniture and cleaning detailed areas at a time, then an “air-to-water” system will deliver enough heat to do the job. If the unfortunate circumstance occurs that your vehicle is wrecked or totaled, unlike a slide-in system that you could remove from the wrecked vehicle and place in a new one, with the PTO system you not only wrecked or totaled your vehicle but also your truck mount system.”PTO” Power Take Off systems operate by taking power from your vehicle’s transmission or drive-train system to run the truck mount’s drive system to turn the vacuum blower and pump. Since the temperature of the coolant (water) in the outer tube can be regulated by the vehicle’s thermostat, there is no need for a way to divert the coolant away from the outer heating tube or regulate the water flow in the inner heat exchange tube.Both systems do a fine job of heating the water. Make no mistake about it, easy and safe operation, no matter what the system, is only determined by the common sense of the operator. The advantage of the PTO systems is that they can be very easy to operate.
So it only goes to follow that the optimum air flow for dual or two floor wand cleaning is double that or around 480cfm. Yet, some systems are made to be more appealing by incorporating giant housings that display lots of extra controls and gauges that you don’t really need and are just going to present you with down-time and extra maintenance expense. . So just look out that you aren’t purchasing components that will never reach or be used at their peak efficiency. Ultimately, this will substantially increase the otherwise normal wear and tear on your vehicle’s systems. Think about it .”Slide-in” Slide-in systems come in an array of configurations, from very economical yet powerful, simple designs that are easy and cheap to maintain, to extremely expensive, large, over compensated systems that, much like PTO systems, can be very hard to work on and very labor intensive and expensive when you have to get them serviced. (Optimum Performance: 15Hg, 240cfm)Vacuum is measured in two ways “lift” and “air flow”.• Physical Conditions You “Have To Have” To Clean Carpet1. Also, they are extremely versatile, allowing you to install them in a variety of configurations and vehicles. There are also systems (PTO and Slide-in) that incorporate large blowers that are built correctly. Other than having to purchase propane gas, there are several positives to be aware of with a propane heated system. If you think about the fact that all slide-in systems use the same three components to operate, then it is easy to see that they all produce the same results, no matter how they are “packaged.
Many manufacturers don’t tell you that you can’t or won’t clean with 240°, but simply attempt to mislead you with Custom Gear Powder Metal Parts for sale overblown numbers. And I know, we all call it “steam-cleaning” but, the truth is, carpet cleaning is done with extremely hot water and not steam. The optimum amount of air flow for single floor wand cleaning is 240cfm. A hose is run from the tank to feed a hot water heater inside the van. The thing about slide-in systems is that they all operate using the same three components, an engine, a vacuum blower and a water pump. This is accomplished by letting the water flow through a metal (usually stainless steel) tube or coil surrounded by an outer metal tube or shell which is filled with hot engine exhaust (air). There are two things to look for with an air-to-water system. This means that if you want to run your truck mount system, you must run the vehicle at the same time. Generally these systems are “water-to-water” heat exchange systems so they also harness the heat of the vehicle’s coolant system to heat the water.• The Bottom LineThe bottom line is, BE AN EDUCATED BUYER! Some systems are advertised as simple, some as large and therefore giving the appearance of being more powerful, some are promoted to be easier or safer to operate.3. But, since there is no way to regulate the heat of the exhaust air in the outer tube it is better and safer to be able to divert the hot exhaust air away from the inner water exchange tube when not cleaning
