Turning backwards for cleaning
"Turning the fan backwards for cleaning purposes Air-cooled condensers or air-cooled gas coolers usually have fin plates on the tubes. However, this means that the unit can easily become dirty. Leaves and other foreign bodies get stuck. This changes the parameters of the unit inadmissibly - for example, higher condensing pressure - and necessitates increased service in the autumn, for example, in the form of cleaning with high-pressure cleaners. The utility model DE20218951U1 of 06.12.2002, which was the first in the refrigeration and air-conditioning industry to successfully reverse the rotation of the fans for cleaning purposes, originates from Markus Mauer, a specialist in the machine laboratory for refrigeration systems at Linde AG in Cologne, which was taken over by Carrier in 2004. Once a day, preferably at night and/or when only a few fans are in operation, the fans are turned backwards one after the other for 5 minutes each to blow the apparatus free. This means absolute freedom from maintenance throughout the year. The process has become the standard in the industry; for example, this principle is used in refrigeration systems for the supermarket operator Kaufland with controls from the companies Wurm and Eckelmann. https://www.freepatentsonline.com/DE20218951U1.html"

I would like to put up for discussion whether this post is worth inserting or not. I'm new here and have had to listen to a lot of nasty words due to some rookie mistakes. So, is the post something or is it not?--GrauerMoench (talk) 13:59, 21 May 2021 (UTC)
