Wise words as ever Mac and very true!

pmegs I got these from a UK company called G&S penrith. I will try and find out who makes them and will then post!

For a high pressure piston pump you need a 5 micron system. Reclaim units rely heavily on good pit design. Having enough settlement time is crucial. Most of the work cleaning the water is done by the pits so you need to ensure these are large enough before pulling the trigger on a reclaim. Have...

Today I received some imeg nozzles and some pmeg. I could not see much difference with the imeg but tge pmeg definitely kept its shape without misting for a longer distance than the meg. My complex impact testing meter (my hand) felt more impact with the pmeg. For a few dollars it would be worth...

I am about to try just this using imeg nozzles. I will post my results!

tip sizes Wow, I never realized that there would be that big a difference in impingement with these types of nozzles! This is for an inverted L machine so I guess I need to size up the gpm and spray angles. Are the veespray tips you mentioned from "spraying systems inc?" Any idea on the ones...

Does anyone know what the optimum distance from a vehicle is on a pdq or similar touchless machine. In particular the front and rear.

It is best to know the chemical strength that is being applied, rather than gi by tip sizes. Wheel clean soaps can vary dramatically in strength. A titration kit is what you need.

I concurr with Chaz. You can get clean windows and you can get a great clean even with real dirty cars. You just need the right chemistry. I assume your water is softened. You might try increasing the titration of the blendco low ph to 20 drops! I normally set my sites up so whatever drops it...

I agree with mac on the profiling of the car from a gantry style machine as distance from nozzle to car is really important. Inverted L machines do tend to get better soap coverage on the front and rear though! I do like the machines that have the soap not coming from the same nozzles as the...

I have seen cars reversing in a friction iba wash when it was washing the rear, pick up truck with barbed wire in the back getting it tangled up in the brushes and scratching the truck and people throwing out their side mirrors during a wash to claim for replacement mirrors. The general public...

I would try increasing the dwell after the low ph, to allow it to tackle those eyebrows. add 5 seconds-then test then add another 5 if this is still no good. The extra run off time will also stop it from neutralizing the high p.h. The strengths look pretty good!

What sort of dwell time do you have between applying low then high? Then how long between high then washing. It seems like you are on the right track with the strength. Is your softener working ok?

Yes. 13 grains is pretty hard and can mean you need up to 50% more chemical to do the same job as soft water. Your membrane life on the R.O will be dramatically shortened also. You need that softener!

Great tip MEP..I will be using that one!

Any rep that does not titrate when supplying touchless cleaning chemicals should not be a rep! If interested then get in touch with Whiting Systems and order the Smartbrite xtreme low pH and Tornado Xtreme high pH soaps. These are really concentrated with fantastic cleaning results. If your car...

What dryers are these? Looks like a nice set up!

I'm on my way!

I see a lot of European manufacturers now adopting a matt black finish on the equipment. I often thought that this will probably not look great when chemicals and limescale sit on the surface. I was right - they look bloody awful in no time. When designing equipment, considering the long term...
