When starting an industrial contract cleaning business, one of the first requirements is to choose the right high pressure water cleaner. It will be your number one work horse and most essential piece of equipment.
Choosing from the variety of available models of pressure cleaners can be daunting, so this guide will provide the essential information you need to help make your decision.
Deciding Between a Petrol- or Diesel-Driven Pressure Water Cleaner
The first and most important consideration is which power source is best for your machine. Petrol-driven water cleaners are suitable for a variety of applications that require a high pressure output. They are relatively low in price and are capable of generating considerable cleaning power.
However when you have the need for day long operations and a long lasting, durable unit, a diesel-driven pressure washer cleaner would be the better option. The diesel-operated machine can provide a higher rate of water flow at an increased pressure and can operate non-stop for a full day and more. The main advantage with the diesel engine over its equivalent petrol driven machine is that it has the ability to operate longer using the same amount of fuel. The diesel fuel is more energy efficient in the way it changes heat to usable energy. It uses air compression and does not need spark plugs like the petrol engine.
Additionally, the engine is much less likely to fail from mechanical related problems. The result is a much more durable and longer lasting machine, entirely suited to the heavy demands of industrial cleaning operations.
Knowing Why Hot Water Is Important
Having decided on the power source for your machine, then the additional choice between hot and cold water models can be deliberated. When contracting for jobs for construction sites, commercial kitchens and factories, the hot water model will be indispensable.
A hot water model is best for the many jobs where you are likely to encounter significant amounts oil and grease. It will offer a much better performance than a cold water model can provide because:
- The combination of high water temperature with extreme pressure creates an abrasive action to loosen the toughest grime.
- The heat and steam create a natural emulsifier that provides plenty of cleaning power but also does away with the dependency on cleaning agents and chemicals to help save money.
Making Your Pressure Cleaner Last Longer
After making the considerable investment in your prime piece of equipment will want to rely on it to operate perfectly for many years to come. Here are some tips to help keep your machine in first class shape and protect your asset:
- Replace the high pressure nozzles at six month intervals
- Change the oil in the pressure pump after it has operated for around the first 60 hours and change annually from then onward
- Clean the water screen filter every week
- De-scale the heating coil yearly and remove any burner soot
- Make sure never to start it without water
One of the critical components of your pressure washer is the hose. Check that the hose is made of a rubber compound and is reinforced with steel wiring. The hose rating should be imprinted on it and should be approximately rated to 4500 PSI or greater.
Should you need to store your cleaner for an extensive period, prevent damage to the pump and heating coil by draining all liquids from the pump, relieving line pressure by squeezing the trigger gun, turning off the power supply and disconnecting the inlet.
Make sure that your pressure cleaner is backed by a solid warranty. Quality models should come with the minimum offer of a one year warranty on the pump and frame, but the more rugged models often give up to a six year guarantee.
You will also benefit from choosing a supplier with a service centre and fully trained staff on hand.
