Commercial Pressure Washer Basics
by Ian Pearce
Commercial pressure washer units are
generally used in maintenance operations where many hours of
cleaning are performed each week.
There are many considerations to keep in mind when selecting a
unit for your operation.
Pressure washers are becoming more and more indispensable as new
versatile units come to market that enable them to be used in
hitherto labor intensive operations. Cleaner equipment lasts
longer and performs better and pressure washers allow for
significant time savings so the equipment can be cleaned more
often.
There are two basic categories of washers, hot water and cold
water units. Which unit is right for your operation depends on
the work that needs to be performed.
A hot water commercial pressure washer is an appropriate choice
when the surfaces to be cleaned have oil or grease on them.
Similar to what happens when washing dishes, hot water is much
more effective when combined with soap in the removal of tough
greasy stains. If you wash your dishes in cold water, you notice
how much more difficult it is to get greasy stains out.
Don't buy the wrong machine for the job based solely on price.
You will regret it because cleaning will become a nightmare
instead of a quick effective process. Keep in mind also that
many solvents or detergents will have a minimum temperature at
which they are most effective in removing stains and dirt.
Using them with cold water pressure washers will severely
diminish their performance.
A cold water commercial pressure washer is an appropriate choice
for jobs that don't involve greasy stains and the like. The
benefits include a lower parts count and typically a lower cost.
They are not as effective at cleaning and take longer because
heat helps a lot in the cleaning process. Some applications may
require cold water. Also, some surfaces may be sensitive to hot
water and must be cleaned with cold water.
Not having to heat the water is a real energy saver and can
reduce costs significantly when applied to the right job. A
typical example of the use of a cold water pressure washer is
cleaning a wood fence prior to painting.
In this example, we don't expect to encounter high soils or
greasy stains. |
