CustomKraft MultiPressure System really could get a patent?

So I was emailing someone about CustomKraft equipment and did not remember the company’s name…. why would I? I have never actually seen their equipment in real life. Do you know why? The person I was emailing said it cost $77k for a 6 bay unit. LOL πŸ™‚ To put that in perspective a Jim Coleman pump stand would cost $50k for the stand and an extra $12k with the spot free. Then the cheapest cheap stuff (Which looks like resturant shelves…. might not be but the design is repurposed from somewhere…. or worse design ever…. I believe.) Etowah Valley Equipment cost $22,699.85 supposedly they come off the price also (this is list).

Anyway I like the idea of CustomKraft equipment but since every car wash basically has the same system as described in their patent I am not sure how they got a patent…. sure they are describing bypassing and low and high pressure but no one ever did this? Well it does not really matter anymore…. their patent expired on or before August 31,2010.

The present invention generally provides a car wash pumping system which can dispense any number of additional chemicals at a low-pressure utilizing a high-pressure pump without the necessity of an additional pump, pumping controls, and fluid lines to the boom and wand assemblies. The present invention may be easily installed within existing car wash systems and is of a low cost and low maintenance design. Further, the present invention does not require additional lines to be run to the boom and wand assemblies thereby not requiring additional means to prevent the freezing of these lines, such as the application of heat tape or a closed loop system, both of which are time consuming to install and expensive to operate. Further, the present invention allows for the application of cleaning chemical solutions at a low-pressure to prevent the unnecessary waste of these chemicals as well as reducing the hazard of splashing these chemicals upon the operator.

One thing that is funny…. the only thing I have heard around this system is it is “wasteful”. Personally I understand the argument and yes purging the lines it technically wasteful but their system is still very high tech for old crusty 1982 tech! LOL πŸ™‚

Also if you ever wondered how their system worked…. well I guess check out the patent?
