Low pressure Soap

I am trying to connect my low pressure soap above the boom to speed up the delivery time . right now it takes about 25 second for pre soak and tire cleaner to reach the wand.if anybody have done and it helped to reduce the delivery time please let me know.if you can provide the diagram/picture that will be greatly appreciated.also how you protect it from freezing in cold weather.
Thanks

I am interested in this problem also, Why doese it take so long for the low pressure items,, presoak,tire cleaner,soapybrush,, to reach the nossle ??? When the source is right at the manafold over head ??
As for freeze protection, we have hot water line running a circut bundled to the noses thru out the six bays, this hot water is turned on by the weep system when it gets cold.

As far as the delay in delivery of the product, it all has to come out that little tiny nozzle on the end of the wand. The most common tactics to reduce changeover time include higher pump pressures on products, larger poly supply lines going to the bay (3/8" instead of 1/4") , and smaller (1/4") wirebraid hoses going from the boom to the trigger gun. If you want to get fancy, you can build a system with a delay on timer that will allow full pump pressure for about ten seconds,then a reduction in to normal operating pressure. It will take a solenoid, timer,and some wiring for each function.

Paul, a manifold is easy to build. But instead od trying to describe it, just go to to windtrax.com, download their catalog and look on page 18 for a diagram.

Thanks Greg,
I do have 3/8" hose from pump to boom and from boom to wand is 1/4". I am using flojet pump with 95psi and on pump stand air regulator is 75 psi. I will try to find out if my timer have any delay option. i am using dixmor 2000 timer.Greg I realy appreciate your help. let me know if i can do any thing else e.g. different pump ect.

The delay off setup is not built into anyone's unit. The system I'm basically talking about is using a procon pump/motor setup with the pump pressure turned up to 150 psi or so. This will flush the line going to the trigger gun quicker. After about ten seconds (user adjustment) The delay-on timer will turn on and energize a solenoid that will have a pressure regulator downstream of it. This will reduce the pressure output to whatever the regulated pressure is. I have never had one of these systems. However, I did have a SS that I pumped presoak at 100 psi via a procon pump out a 3/8" poly line and was quite pleased with it's performance. Your best bang for the buck will be to install manifolds at the boom. this will probably get you to 10 seconds changeover.

I have seen at least one timer that will stop countdown when functions are changed to allow for product changeover.

If there is a foam generator involved make sure it is located in the bay and not the equipment room, this would help with delivery time as well.

Along these same lines , I have the 1/4 inch hose from the pump room and the soap goaes out one tube with the air from another they are mixed at the manafold above the bays. The air lines seem to collent fluid at the relays at the pumps in the pump house. I dont understand how fluid can get to this point unless it is comieng back from the bays. Any thoughts. ???? thanks

you are using 95psi on liquid and 75psi on air.Icrease air progressly to about 85psi;it might solve the problem.The difference between air and liquid should be not that much.Meaning,if you choose 50psi for liquid,air should be about 40 psi
