    PDQ Laser 4000

    Docking Dryer rollers are different from bridge and trolley rollers. They require bearings for the extra weight. If you are considering improvements, then think about a replacement stainless bridge from PDQ. They are about $30,000 dollars and come with all new motors, gearboxes, covers, festoon...

    Color Scheme for our Car Wash

    So I voted for 2 because it catches the eye from the road, but the sign works better on 3. If you reversed the ombre it might work better, that would put the yellow at the bottom and help the giraffe, sun, and lettering stand out more.

    Arch covers

    I forgot to add that the first picture is of an arch cover that is 10 years old.

    Arch covers

    These are pictures of the playground padding installed. Initially I just cut for the nozzles. This is cheaper and easier but will allow the outer padding to slip down occasionally. After seeing the new Razor Edge arch cover, I made one with a piece of 1" tubing. This one locks the padding in...

    Adding a drive through wheel chemical applicator

    I simply programed for the wash to do the undercarriage with rust inhibitor. Then rather than plumbing from the rust inhibitor solenoid to the high pressure pump, I plumber out to the bay.

    Adding a drive through wheel chemical applicator

    I have them on all 9 of my Laserwash 4000's. It didn't drive sales, but it does do a good job on the wheels and rocker panels. We use to have most of our customers spraying their rooms before going in. Now almost none spray there rims, they just buy one of the washes with the wheel cleaner.

    Arch covers

    The black rubber pipe insulation from Lowe's (part number 21377) goes over the bare arch to insulate it and make it large enough for the inside dimensions of the post padding. The post padding then goes on the outside.

    Arch covers

    We use playground post padding. They come in 8 foot sections and a variety of colors. You can purchase them at a playground supply store or online. It still runs about $120 for a lower and upper arch with ties and pipe insulation, but they have about a 10 year life span, dramatically reduce the...

    Water damage to IBA control box

    Are you sure this was caused by water damage? It is unusual that the VFD closest to the vent didn't get wet, just the one sandwiched between the other two. I would think that this could only happen if the water dropped straight into the Trolley VFD, which would lead me to check the door seals.

    Laser M5 problem

    I would start with the reclaim solenoid valve. If it doesn't close the reclaim will continue to feed the pump as long as it has more pressure than the overhead tanks inlet side of the pump.

    Recommendations for new touch free wash

    You could just replace the 4000 bridge with a stainless steel one from PDQ or Wash World for less than $35,000. If a distributor installs them then they come with warranty. The 5 we installed in 2017 still run great.

    Laser 4000 stops at the back of vehicle!

    Also don't forget to make sure the ultrasonics are clicking.

    Laser 4000 stops at the back of vehicle!

    I am assuming that the machine is getting stuck on the tbar at the rear passenger side of the vehicle, based on what you have checked so far. I would start by checking the interposing relay. It controls the passenger side measurement. If it is not working correctly then the trolley will go wide...

    Do you have a Virtual Treadle?

    PDQ 4000 still a good machine?

    They're fairly simple to work on. Parts are still readily available. None of the new touchless machines can produce a better car, they just offer more show. A couple of things to think about would be what version chip are inside the A-5000's mounted to the doors of J0 and how much is it to...

    After thoughts from the 2019 Nashville Car Wash Show

    I use to go to the show every 3 or 4 years and was always amazed at the new stuff on display. Now I go every year and it seems like there are only a couple of new things to see each year, but I don't go for the equipment anymore. Now I go for the people. What I learn from talking with others...

    Touch Less Automatic Chemicals

    I used the CPS-100 with a light blue tip for 3 years and it worked fine most of the time. There were a couple of times a year that it wasn't able to get the road film off. After I worked with CSI on their new setup, I was able to get the road film off during one of the challenging times. Then I...

    Touch Less Automatic Chemicals

    Now that the show is over and CSI has finally introduced their new soaps for touchless car washing, I can say that I have had good luck with their 205 mixed with 715 for lo pH and 224 mixed with 515 for high pH. I tested this setup for them in November and found it to be really close to our JBS...

    Touch Less Automatic Chemicals

    I run CPS-200 with a red tip, CPS-201 with a pink. In order to better deal with the eyebrow, I use CPS-104 with a light blue tip and CPS-105 with a pink.

    Touch Less Automatic Chemicals

    I use JBS's COMPASS line and apply the boost through a double injector.
