Now that you’ve decided to move away from the realm of petrol h.p. washers in electric h.p. washers, it’s time to get down to the heart of the matter. More than a checklist of a buyer’s guide. You must first discuss the various types of electric high pressure cleaners, realm, and then talk about some considerations to be taken regardless of what is, finally, the purchase.
Four Basic Classifications
There are only four types of market pressure washers, particularly in the realm of electrical sector. They are handheld, cold water, hot water and wall washers. Now, handheld washers are strong motors and are quite portable, but usually do not have enough pressure or power to handle large processes. If you need pressure in the range of 2000 psi or more then opt for cold water or hot electric pressure washers.
Cold h.p. washers are ideal for daily applications and 3000psi washers usually have enough power and strength to strip layers of paint. However, if it is to be mostly with grease, bitumen and oil, then choose a hot water pressure washer. The last category, called wall washers, is ideal for large garages and production facilities. They depend on the 3rd stage of input power and draw a lot of energy and water. Usually, national and more commercial places, do not require so much power and pressure.
Cleaning Power Unit
It’s not all PSI or GPM (PSI stands for pounds per square inch and GPM stands for Gallons Per Minute). In fact, it is not possible to rely on just one of these readings to determine cleaning efficiency. The best way to measure cleaning power is to multiply the two units together. So PSI x GPM will give you an accurate reading of the power. Now, once you have obtained this reading, you use it to determine the amount of power you need. For most applications 6000 to 8000 cleaning units is enough.
Hot Water Or Cold?
Very valid question, do you not need cold water or hot water for pressure washing? It’s just what the washing will be. If you are dealing predominantly with oil, grease or stubborn stains then opt for hot water. In addition, hot water tends to reduce the time of, activate the cleaning chemicals better and also disinfects areas.
If you choose a hot water pressure, washing machine, then make sure you are using a heating coil with a ½ inch diameter or more. Narrow coils tend to reduce the actual pressure of the machine. Also, the coil design should be spiral rather than direct or elliptical to avoid soot build-up over time.
Portable or fixed pressure washer?
Once again it’s all about what kind of application you have in mind. If you don’t need to move the pressure washer around and think about keeping it confined to a room, a fixed unit will be the best option. However, remember that maintenance and maintenance is usually more expensive than fixed, unit maintenance. On the other hand, a handheld unit is more convenient to clean with in more areas. They usually have a heavy top and rely on rubber to roll.
Safety Features In Matter
Regardless of the type of pressure washer you choose, you should ensure that the following safety features are present.
Auto Shut Off – helps to turn the heat source off when there is a shortage of water supply.
Gun – A gun is always better as it allows the user to have complete control over the water jet.
Thermostat – Having a thermostat gives you complete control over the water temperature, something that comes at your fingertips in case you plan to cold wash and hot wash with the same pressure washer.
Float Tank – This prevents contamination of the water source and helps to clean better.
Ground Fault Switch – Having the pressure washer on the ground is vital to prevent the user from electrocution by sudden spikes in current.
Safety Valve – This valve allows you to shut off the water supply to the pressure washer forms the heater when during falls, breaks or any other emergency situation.
