Diesel Pressure Washers
October 12th, 2009There is a straight cost issue when deciding whether to go for a petrol or diesel pressure washer. Diesel powered will last longer than a petrol driven pressure washer but petrol is cheaper. A diesel engine will use 10% to 20% less fuel to achieve the same work, then there is little cost difference to pay back the increased price of the diesel pressure washer.
However, if you buy your fuel from a fuel distributor and get agricultural diesel, it only costs about 25% of the cost of road fuel. When you use red diesel and you use your pressure washer for 50 litres worth, or four hours per day, five days per week, for 48 weeks of the year, then your savings will be approximately £1500, at February 03 fuel prices.
The amount saved is more than the difference of the purchase price in the first place. If you only use your pressure washer for one or two hours per week, the added cost of investing in diesel power, would not provide enough savings, to pay back the added cost of the investment.

Soda Blasting
October 9th, 2009Sodablasting is a process where sodium bicarbonate is applied against a surface using compressed air.
Sodablasting is a non-destructive method for many applications in cleaning, paint stripping, automotive restoration, industrial equipment maintenance, rust removal, graffiti removal, masonry cleaning and restoration, boat hull cleaning, food processing facilities and equipment.
Demon offer a complete package for those looking to offer Soda Blasting as part of their business. Visit us at our HQ and we will demonstrate how the products work, once you are up and running we offer ongoing technical support and are stockists of Armex soda blasting media.

Industrial Pressure Washers
October 8th, 2009Pressure washers fall into three main product categories, which determines the material qualities, the cost of manufacture and therefore the sales price asked in the market place.
1. Hobby machines: these are the cheapest on the market and can be determined by the use of aluminium cylinder heads, high speed motors and stainless steel pistons. They are designed as limited life machines which should only be used on a 60% duty cycle. This means that during a 1 hour period the machine should only be worked for 36 minutes in total. In practice this means that if you wash your car and put it away that’s OK. If you spend three hours washing everything in sight the machine will overheat and excess wear will occur shortening the life of the product. Petrol powered machines have lawnmower engines and are direct coupled to the engine. Hoses and lances are all plastic and not very durable.
2. Commercial Machines: the next level up from hobby machines, they are better constructed with more features. Beware, some are high speed motors and some still have aluminium cylinder heads. What you want at this level of product is a brass cylinder head and preferably ceramic pistons and 1450rpm motors. Commercial machines can be 2800rpm or 1450rpm. 2800rpm motors are 60% duty cycle and 1450rpm are 100% duty cycle. (100% duty cycle can be used continuously.) Petrol and diesel powered machines tend to have pumps running at 3000rpm or 3600rpm and are better than hobby class machines with some even having brass heads and ceramic pistons too. Don’t expect then to draw their own water, this may work for the first couple of months but seal wear will soon cause the performance to drop dramatically.
3. Professional Machines: this level is aimed at professional users who want machines to work reliably day after day. All professional machines have 1450rpm pumps and motors, they will all have brass cylinder heads and the hose and gun will be steel reinforced. All 1450rpm pumps are designed to be self priming and will draw their own water if fitted with a suitable filter. Petrol and diesel powered machines will all have an intermediate reduction gearbox which allows the engine to rev to 2900rpm but the pump still revs at 1450rpm.

Petrol Pressure Washers
October 7th, 2009
There are three main classes of petrol or diesel pressure washers:
1. Hobby – usually petrol driven, up to 5hp and use a vertical crankshaft engine, like a lawnmower, and have a small wobble plate pump hung underneath the engine. Like your lawnmower these are designed to be used occasionally for short periods of time. They won’t suck their own water either.
2. Budget priced – look the same as professional equipment but all the corners have been cut. You can identify this type of pressure washer, as it will have no reduction gearbox between the pump and engine. Reduction gearboxes are expensive but allow the pump to turn much slower. This means that the pump is not designed to suck its own water. It may do when new for a few months but it is primarily designed to be fed from a hosepipe. Check with your water supplier to see if this is permitted. (Most do not)
3. Industrial – what you need if you earn a living from pressure washing, or use pressure washers for long periods of time. Characterised by having a reduction gearbox which allows good suction and top of the range engines, designed to last, with quality filters and fittings.

Hot Water Pressure Washers
October 6th, 2009We often get asked why you need a hot water pressure washer?! Well you need hot water and chemical to completely remove oil and grease and to prevent the oil and grease from reforming elsewhere on whatever you are cleaning. The hot water melts the oil or grease and the chemical emulsifies the oil or grease so that it can be effectively rinsed away.
But I can remove oil and grease with my cold wash and chemical can’t I?
No, you can spread it around a bit and some will wash off but you will never remove the microscopic film of oil left behind unless you wash it with hot water and chemical.
I have heard that you can pump hot water through a cold water pressure washer – I could do that rather than buy a hot water pressure washer can’t I?
Some pressure washers can do this, the Kranzle range of cold water pressure washers and our Demon range can happily pump hot water, provided it is pressure fed into the pump and it is below 60°C. This is better than cold water but not the same as a hot water pressure washer. It is also true that the Demon Storm 1 and 2 can have modified seals fitted to enable water to 80°C to be used. We have made a number of these modified pumps and they are working reliably with the customers who bought them. With a hot water pressure washer cold water only flows through the pump. It is then heated by a very hot flame burning either diesel or kerosene via a heating coil to heat the water. This water leaves the machine at about 90°C to 95°C.

Armex
September 25th, 2009While the idea for ARMEX® started with just plain baking soda, as the world’s leader in bicarbonate technology ARM & HAMMER® formulated more than a dozen unique medias to specially meet industry surface preparation requirements. ARMEX Cleaning and Coating Removal Systems have become an effective, economical and environmentally superior method for cleaning, depainting and degreasing across the country, and around the world.
Why Baking Soda?
It is granular – suitable for use in pressure pots, cabinet systems and as an additive for pressure washer systems.
It is sharp – baking soda crystals delivered under relatively low pressure but at high velocity will scour virtually any
coating from any substrate.
It is friable – meaning it fractures into smaller particles intensifying the cleaning action while softening the impact on substrates.
It is relatively soft – with a Moh’s hardness of 2.5, it will not damage most substrates. (Always test a small area first)
It is benign pH of 8.2 – provides a superior worker and environmental profile, before, during, and after use.
It is water soluble – dissolves in water for easier disposal and can even be washed down the sewer.
ARMEX® is not just baking soda. It is a specially formulated sodium bicarbonate.
Nozzles – you can’t get pressure without one!
September 17th, 2009Look at the end of the nozzle – it will have a four or five digit number which gives the angle of spray as the first two digits. The next two or three numbers are the size. (i.e. 15045 is 15° spray angle with 045 size aperture.)
Pressure starts and ends at the nozzle. The volume of water pushed down the hose and forced through the small hole determines the pressure on the gauge. Try taking the nozzle out and then pulling the trigger. You get virtually no pressure registering on the gauge.
The golden rule when diagnosing a loss of pressure is to start at the nozzle and work back to the pump.
