Sioux Water Pressure Washers
Sioux Water Pressure Cleaners

Different Machines for different Applications… What Type of Cleaner is Best for You?

Cold Pressure Washers

Sioux cold pressure washers are excellent for lighter cleaning jobs such as washing off dirt, dust and mud, and maintaining vehicles and grounds. Cold pressure washers are easy units to operate, since water is not heated, therefore there are fewer components, and less maintenance, The initial cost and operating expense of cold pressure washers is less than most other cleaning methods. Units come complete with pressure relief valve and glycerin felled pressure gauge.

Ratings:

• 2 – 24 GPM
• 500 – 6000 PSI
• Electric Motor, Gasoline Engine or Diesel Engine

Hot Pressure Washers

Sioux high-pressure hot water washers are excellent for removing oil and grease, dried-on mud. thick dirt, sludge, paraffin, and for cleaning walls, floors and vehicles. Hot pressure washers greatly increase the power of cleaning compounds, compared to cold pressure washers. Units come complete with high temperature limit switch, glycerin-filled pressure gauge and pressure relief valve. A steam option, which produces 290-300°F saturated steam (212°F after discharge from gun nozzle), is available on all fuel-fired hot pressure washers.

Electrically Heated Hot Pressure Washers

Electric hot water pressure washers use electric immersion elements to heat the water with no fumes or exhaust. All-electric cleaning equipment units are great for cleaning in locations that require clean emissions and air quality or hazardous locations where fuel-fired units are not approved for use. Sioux all-electric models require 3 phase electrical power. Sioux manufactures two different lines of all-electric hot pressure washers. The EN Series and E Series. Units meet low NOx requirements because they do not burn any fossil fuels to heat the water.

Sioux’s EN-Series All-Electric Pressure Washers

• Extra heavy-duty industrial design built for use in the most rugged environments.
• The EN-Series includes explosion-proof models, designated by an XP in the model number, for use in hazardous locations.
• Most EN-Series units are combination machines, which means they can be used as either a hot water pressure washer or an industrial steam cleaner.
• Typical applications for these units are in the petroleum and mining industries.

All-Electric E Series

The all-electric Sioux E Series pressure washer is designed for industries that require the same cleaning power as our larger EN Series pressure washers in a more compact and portable design such as

• Pharmaceutical manufacturing
• Chemical manufacturing
• Food and beverage processing
• General manufacturing

Features

• Sioux’s E-Series electric pressure washers all come standard with steam cleaning functionality
• Provide instant and continuous heat without the hassle of preheating storage tanks or a volume of heat transfer fluid.
• Standard features include a NEMA 4 electrical enclosure, stainless steel float tank, long-life heating elements, and adjustable digital temperature control.
• A wide range of options and configurations are available in any voltage in 50 or 60 Hertz.

Oil, Gas & Propane Powered Steam Cleaners

Sioux steam cleaners provide 325-F saturated steam (212-F after discharge from gun nozzle) at 100 PSI to remove grease and oil, sterilize, disinfect, and degas. Steam is great for cleaning surfaces before painting or other treatments, flushing away poisons and chemicals, dissolving resins and tars, killing algae and mildew, melting ice, and thawing frozen valves and pipes. Units come complete with high temperature limit switch, glycerin-filled pressure gauge and pressure relief valve.

All industrial steam cleaners are not equal in performance. The Dakota II line of gas and oil fired steam cleaners provide up to 320°F (160°C) saturated steam at the nozzle which produces up to 333% more cleaning impact when compared to other brands that only produce 250°F (121°C) saturated steam. Sioux Dakota II industrial propane powered steam cleaners feature an extra heavy-duty industrial steel frame that is built for extremely rugged operating environments such as mining, petroleum, manufacturing, contract cleaning, and the transportation industries. Sioux units are available in a variety of voltages at 60Hz or50 Hz and utilize either an oil (diesel), natural gas, or LP fired burner.

Ratings:

• 1.6 – 8 GPM @ 100 PSI @ 325°F
• 234,000 – 1,125,000 output BTU/Hour

Combination Cleaners

Sioux combination cleaners combine a cold pressure washer, hot pressure washer and steam cleaner all in one unit. A combination cleaner is ideal if several types of cleaning are required. Sioux combination cleaners provide 325-F saturated steam (212-F after discharge from gun nozzle) at 100 PSI on steam cleaning cycle, hot water at 200-F on hot pressure cycle, and cold water on cold pressure cycle. Units come complete with high temperature limit switch, glycerin-filled pressure gauge and pressure relief valve.

Which is Best… a Hot Water Washer OR a Steam Cleaner?

Myth: Steam cleaners are outdated.

Reality: There are many applications where a steam cleaner may be better than a hot water washer.

At Sioux, we have been building both types of machines for many years. There are some advantages to using hot water washers and some advantages to using steam cleaners. Each cleans in a different way. Determining which machine is best depends on the application.

• With pressure washers, dirt and grime is blasted away, under pressure. Heat will improve the result if melting is required, and use of the proper detergent will enhance cleaning.
• Steam cleaners are best when the substance to be removed turns from a solid to a liquid, or dissolves, with the application of heat. This is the case with grease, oil, tar, many petrochemicals, ice, wax, food products and similar materials. The substance is melted or dissolved, rather than pushed off of the surface. Use of proper detergent will enhance steam cleaning.

With a Dakota™ Series steam cleaner, when heated water at a temperature of 320°F and a pressure of 250 PSI flashes into vapor as it passes through the steam nozzle, there is tremendous expansion, producing about the same impact as a 1,000 PSI pressure washer, with 86% more heat transferred for cleaning.

If heat is what is really needed for cleaning, a steam cleaner is the better choice. In addition, a steam cleaner (vs, a hot water washer) offers the following benefits:

• Operates with less power consumption, reducing your electric bill,
• Requires a smaller electric circuit for installation, and therefore may be used in more locations in your facility,
• Uses less water during operation, reducing your water and sewer bills, and reducing the volume of wastewater to be processed,
• Produces less splattering and splash-back onto the operator and in your facility.

All steam cleaners are not the same. At comparable flow rates, a 320-F steam cleaner produces approximately 40% more steam and will transfer approximately 13% more heat to the surface than the 290-F steam cleaner. The increased heat and steam also significantly increase the cleaning impact, as illustrated in the chart below:

Pressurized Water Temperature Before Exiting Nozzle as Steam	% Increase in Cleaning Impact of 320°F vs. Lower Temperatures
320°F vs. 300°F	+34%
320°F vs. 290°F	+58%
320°F vs. 280°F	+118%
320°F vs. 265°F	+167%
320°F vs.250°F	+338%

What is more important, pressure or flow?

For a given cleaning application there are many flow/pressure combinations from which to choose. Here are some criteria you can use to select the best flow and pressure combination for your application.

1. Consider the capacity of your water source. If you have a limited water supply then you should probably choose more pressure than flow.
2. Consider how important heat is in your cleaning application. It heat is critical to your cleaning application, then higher flow is better. The more hot water you can move across the surface, the faster you can heat it and clean it. If additional heat would help, a steam cleaner should be considered.
3. For a given horsepower there may be several flow and pressure combinations available. Higher flow and lower pressure for a given horsepower will result in more impact and more work. The example below compares two different 7.5 hp machines. You can see that the higher flow rate option results in 29% more work and 40% more cleaning force.

Example	Rating	% Additional Work	% Additional Force
High Pressure	3.5 GPM @ 3000 PSI	–	–
High Flow	5.3 GPM at 2000 PSI	29%	40%

4. It is commonly believed that lower flow and higher pressure will produce less runoff, and less wastewater to process. This may be true in some applications. But if a higher flow machine can perform the same job faster, then the total amount of water used may be less. Temperature should also be considered to reduce water consumption. It may be better to use a higher temperature rather than increase flow or pressure in order to minimize your wastewater.
