Vac u boom

An innovative and practical waste water capture system to prevent run-off from washing operations indoors and outdoors. A highly effective spill containment system for many hazardous materials. The Vacu-Boom system is engineered to be used in a wide variety of industrial and commercial applications where chemicals and fluid waste must be contained and/or captured and removed from the site. The Vacu-Boom is a hollow, flexible tube five inches in diameter that is placed directly on a hard surface to form a down slope side dam or to completely encircle the wash or containment area. The boom has a C shaped cross section with the open side down. There are small liquid inlet openings on the water side of the boom at the bottom edge. During use, the boom is connected by a 25 ft. vacuum hose to the portable wet vacuum recovery unit.


filtration system

Our mobile Wash Water filtration units are the easiest to use of any filtration system available. Its automatic On/Off , single pump configuration not only reduces the need for maintenance and high replacement costs but allows you to plug it into any 110 volt electrical power supply. The system connects easily to your sump pit pump via hose or PVC. Under normal Non-Hazardous power washing, The Wash Water Filtration units can eliminate your compliance problems. Each model has a capacity to clean down to a 5 micron level or lower and is easily adapted to a “Closed Loop” Zero Discharge system if needed. All materials are corrosion proof providing a low maintenance, low cost and highly effective wash water filtration unit. This system is small, lightweight and compact. It fits easily in a truck, van or trailer and can be moved quickly.

Hot vs. Cold Pressure Washers

All pressure washers fall into one of two categories: hot water or cold water. Because both types of pressure washers offer models with the same GPM, PSI and can clean indoors or outdoors, it begs the question: why do I need a hot water pressure washer when everything else is the same?

The answer is as close as the kitchen sink.

You’ve just had a delicious spaghetti supper and it’s time to wash the dishes. Fill one sink with cold water and the other with hot water. See which cleans faster and better. Even with a heavy dose of soap in the cold water sink, hot water cleans significantly more effective.

Why?

It’s a story as tiny as the molecules that make up water.

We learned in our early school years how everything is made up of atoms that bond together to form molecules. These tiny molecules are in constant motion. With water, the hotter it gets the faster the molecules move, until at 212°F they become airborne and form steam. As we cool water, the molecules slow until they eventually become ice hard.

Svante A. Arrhenuis (1859-1927), a Swedish chemist, researched the heat-energy relationship. In short, he concluded that higher temperatures cause molecules to collide with each other creating energy that can cause the molecules of grease and grime to break free from the surface to which they’re attached.

In other words, cleaning is accomplished by lowering the surface tension.

Actually, there are three key elements--heat, agitation and soap—that work best to reduce the surface tension of dirt and grime. Here’s how each works:

• Heat, as described above, creates a high-speed molecular action that physically breaks the bond between grime and the surface to which it’s attached.

• Agitation is the impact that comes from the water volume and water pressure hitting the surface—the same action that you get when you scrub the dinner plate in your kitchen sink or blast it with a spray of water.

• Finally, soap (often called “detergent” by pressure washer users) chemically breaks the bond between dirt and the surface by reducing the surface tension through water softening agents, alkaline builders (which convert oil and grease to soap so they release easily) or even surfactants or solvents, such as butyl, which literally dissolve organic soils like grease and grime.

Because they bring together in perfect balance all three of these key elements, hot water pressure washers deliver cleaning’s most effective knockout punch.

So how do you know when to use hot water?

If you’re cleaning engines, automotive parts, or anything with oil or grease, you’ll need hot water. Like the dishes in your sink, hot water cuts grease and grime; cold water only pushes it around.

On the other hand, if you’re simply blasting away soil, caked-on mud, or even stripping paint, a cold-water pressure washer will work just fine. Combined with detergent, a cold-water pressure washer can be very effective in many applications.

The rule of thumb is simple: if cold water can clean it good, hot water can clean it better.

Does a hot water pressure washer cost more?

Yes, sometimes two to three times more, due to the complexity of heating hot water while under pressure. Hot water pressure washers also require more maintenance, such as the burner assembly, coil and redundant excess-pressure protection, all of which may need repair over time. Still, hot water pressure washers easily pay for themselves in labor cost savings from faster, more effective cleaning.

How is water heated in a pressure washer?

Water enters a pressure washer from a spigot or tank via a garden hose. It first passes through a high-pressure pump, which speeds the water on its way through a heating coil, consisting of up to 200 ft. of 1/2-inch steel pipe or tubing. The serpentine configuration allows the water to get maximum exposure to the flame (fueled by oil, diesel or natural/propane gas) as it roars through the center or core of the coil. By the time the water rushes out of the coil and through the wand and nozzle, it will have reached temperatures of up to 200° F.

Don’t I need steam, too?

It’s not unusual to hear hot water pressure washers referred to as steam cleaners. While there are a few applications, such as detailing an automobile engine, that require steam, it has been proven over the years that hot water under pressure is a much more effective method of cleaning than steam. That’s because hot water washing has the additional benefit of the water volume impacting the surface. Steam has heat but very little impact force or agitation, which is one of the three key cleaning elements. Still, some pressure washers offer a “steam combination” option where the hot-water flow is restricted in order to create a “wet steam” effect for those rare applications where there’s a delicate surface and the impact of water under pressure could cause damage.

While in that business, Greg purchased over 20 pressure washers, hot and cold, from the local Landa dealership and in 1991 had the unique opportunity to purchase the business from the factory. Greg has always concentrated on servicing what we sell as well as the environmental aspect of our industry. With the addition of Jim Coleman/Hanna car wash line of equipment, we are pleased to represent the top manufacturers in our industries. In the past years, SCE has been the #1 Landa dealership three times, is always in the top 5 and for the past eight years has been the #1 WaterMaze environmental equipment dealership in the world and has become one of the top car wash dealerships in the state.
