Pressure washers are very popular both in the commercial and industrial sectors because they are able to handle tough cleaning jobs and undertake numerous cleaning needs. These units handle their cleaning jobs by accelerating water at very high speeds to lift, dissolve, and wash away tough dirt, mud, and stains. These days, you will find a lot of commercial and industrial pressure washers with different features, flow rates and pressure levels from different manufacturers. Sometimes, their models even feature temperature options to increase their cleaning capacity.
When choosing a pressure washer, it is important to consider the pressure level of the unit to match accordingly to your daily or regular cleaning needs. Most commercial and industrial pressure washers will have a pressure level that ranges from 750 to 4000 PSI. Such high pressure levels are capable and effective in removing stubborn dirt and residues. Their only downside is that they are likely to damage delicate surfaces, which is why you also need to consider and be wary of the surface you are trying to clean.
There are also pressure washers made for light duty cleaning with pressure levels that ranges from 750 to 1000 PSI only. Such pressure washers are suitable for most cleaning tasks such as cleaning cars, garage, driveways, walkway, patio and many more. Most residential-type pressure washers are made for light duty; this means they cannot be used for prolonged or extended usage. However, for most commercial and industrial pressure washers, they need to be made of quality materials so that they can withstand abuse and prolonged usage.
Pressure washers are basically classified into three types – cold water pressure washers, hot water pressure washers, and steam pressure washers. Cold water units use the same temperature coming out of the tap. Hot water units on the other hand use heating coils to elevate the temperature of the water by up to 200° F, giving them a much better cleaning power. Steam pressure washers are perhaps the ultimate cleaning equipment as they are able to churn out 330°F hot wet steam. The advantage of using a steam pressure washer is that not only does it clean the surface you intend to clean, but it also sterilizes it. With regards to the three different temperature classifications of pressure washers, it can be said that the higher the temperature it can generate, the faster it will be able to dissolve the stubborn deposits. The truth is there is a fourth type of pressure washer, a mutant so to speak, as it is able to perform the other 3 types by simply adjusting its settings.
Certain commercial and industrial cleaning applications require the cleaning of dirt, stains, grease, oil, and grime. This is where hot water pressure washers and steam pressure washers prove to be beneficial as the elevated water temperature they spray is capable of melting and dissolving said deposits. Using a cold water pressure washer to remove oil and grease will take a much longer time as the cold water will just harden them. Then again, if your unit has a chemical dispenser accessory, you can use detergents to lift the deposits from the surface it is adhered to.
The flow rate of a pressure washer, measured in GPM, is also equally important. The flow rate of pressure washers ranges from 0.5 to 5 GPM. A higher GPM unit will usually have a better cleaning capacity. However, if a 1 GPM unit will suffice for your cleaning task, it is better to stick to it because it will help in conserving water. In addition to this, if the area you will be cleaning on doesn’t have sufficient drainage system, then a lower GPM would be better. Then again, if a higher GPM meets your requirements, then you can stick to the unit with a higher GPM rating.
The Cleaning Power of Heated Pressure Washers
Hot water pressure washers are great for dealing with heavy duty cleaning and degreasing jobs. The combination of both high pressure and hot water gives these cleaning units exceptional cleaning power which works extremely well in cleaning, removing, and dissolving dirt and oil-based deposits on surfaces. In addition, the hot water it uses also helps in killing any bacteria as it sterilizes the surface you are trying to clean. This is the very reason why hot water pressure washers are highly sought after in the commercial and industrial sectors, particularly in the automotive and food processing plants as they use oil for the lubrication of machineries as well as for cooking. If you use cold water on such deposits, the cold water will only solidify the oil and fat-based deposits, turning them into waxy clumps, making them even harder to remove. This will not pose as a problem for hot water pressure washers as the highly heated will simply melt and flush the oil and fat away.
Steam pressure washers on the other hand take cleaning to a whole new ball game. Since it uses steam and propels it at incredible speeds, the unit is able to clean and eliminate practically and type of oily stains including any dirt, mud, and grime deposits. In addition, since steam is at very high temperature, the operator no longer needs to use any chemicals or detergent to kill bacteria as the steam temperature alone is very capable of doing so.
While cold water pressure washers are good enough for general cleaning tasks, for the best degreasing results, nothing beats the cleaning power of heated pressure washers, particularly if you need to clean oil-based deposits.
When choosing the right pressure washer for you, you need to read about the different factors to consider when buying a pressure washer unit. This will give you an understanding on how to make your choice, particularly in understanding your cleaning requirements. You can also talk to a specialist about this so he can make some recommendations. Just make sure you are talking to a specialist and not a sales agent as a sales agent is only keen in making a sale while a specialist is keen on making both a sale and providing good advice.
