Get your wash system ready for winter

ready for winter


Winter makes special demands of washing technology. Cold, snow, ice and road salt are a challenge for the machinery and the water quality. But whoever successfully meets these challenges also has the opportunity to significantly increase the average wash price by selling higher-quality washes, including the under-chassis wash.

You should therefore get your wash system ready for winter, and ensure that you have appropriate availability. This will make you a reliable partner for your wash customers.

It is particularly important to consider the following:

Check your under-chassis wash unit
Has the routine maintenance been carried out (cable or swivel mechanism, high-pressure pump oil change and oil fill level check etc.)?
Have the high-pressure lines been checked in accordance with BGR500 by an expert, i.e. your service technician and replaced if necessary after an appropriate running time, as prescribed by the professional / trade association?

Check your wash hall
Does the door actuation and door control work properly?
Does the heating work?
Is your wash hall winter-proof (safe from potential slip hazards etc.)?

Check your wash system
Is the wash material of a high quality and visually in perfect condition?
Has the routine maintenance and inspection work been carried out in accordance with the check list and noted in the logbook?
Are the nozzles in perfect condition so that nothing can stand in the way of an optimal wash result?

Check your water preparation unit
Is the conductivity measuring probe in perfect working order? This is very important for ensuring that you have appropriate water quality and therefore washing quality, even in the winter months?
Has the maintenance and checking work been carried out in accordance with the checklist and documented in the logbook?
