The Kranzle Profi series was developed strictly to offer improved successful Kranzle quality for serious industrial continuous operation. And these are the changes. The Profi series exclusively uses oversized gears, oil housings and motors which significantly extend the service life during rough continuous operation. As you may expect from real professionals. The Profi seriess all come with an integrated hose drum, with foldable crank and a 15 metre long high-pressure hose for an extra large operating radius. While on paper these read very similar in performance to the K 2000 series, the design with the integrated water tank not only offers additional protection against temporary shortages/fluctuations in the water supply (say, perhaps due to a toilet on the same water supply being flushed, or a tap turned on) but with this they also offer at the nozzle a useable increase in pressure of aprox. 30% more.
