Chemical Dispensing System

[TEEBOX]

This Summer I attended the Midwest Carwash Association show in Battle Creek.

It seems that all the chemical companies are marketing their Chemical Dispensing Units. I.E. Zep's Assure, Sonny's Chemical concierge and Synergy Solutions System.

I like the idea of having a booster pump to make up for the loss of water pressure from local municipality.

Initially I was set up with Dosatrons but were not effective when water pressure dropped. The flojet/hydrominders worked well for my foaming applications. Dosatrons worked well with non-foaming applications. I.E Presoak, Dry-Aid, Clearcoat Sealant.

So going forward with chemical companies focusing on concentrating their products in to smaller footprints in backroom and using these new idea, I ask does this mean the end of Flojet/Hydorminder tanks?

I have a Dosatron for my presoak that I need to replace. Dosatron from Kleen-Rite is $345 and operate as usual or replace it with a Flojet/Hydorminder tank for $729 set from Vaughn.

Thanks in Advance

There are several reasons why they build new equipment the way they do. One, and probably the main one, it's cheaper without the tanks. With a Dosatron, you're just sticking the unit on and plumbing it to solenoids. Two, a smaller footprint means easier/faster to install, so when these guys sell equipment for an existing wash part of their pitch is minimal down time.

I guess the question is, are you happy with the Dosatron? Will it run for five years without touching anything? Flojets have always lasted at least that long for me.

In critical systems it's nice to have spares. Hydrominder rebuild kits are cheap. Flo Jets are cheap. They are also fast and easy to swap out. . How many spare Booster pumps, motor starters etc. do you want to stock. How easy are they to swap out. Cost?

Was at a new Sonnys distributor set up EE, and they Had the Injector system with Booster Pump, Hydrominders, Dosatrons, and metering pumps. 4 Sets of spare parts needed because...??

I am not a Dosatron expert but why not try a regulator first? How long does your Dosatron last?

I hate to be critical.... but if you double up those small hydrominder setups (left in video) they are about the same size as the Chemical Concierge. Seems larger than the Hydraflex.

A regulator will keep the pressure consistent, but only if it's set lower than the lowest the incoming pressure drops to. I've seen lots of washes where the pressure drops below 20 psi, not enough for a presoak system. If I were to use Dosatrons I'd set it up like in the video, with a VFD pump to maintain a constant inlet pressure.

You can also get a simple booster pump and bladder tank and put it on your incoming water line. That will keep the pressure downstream constant.

Would I install the pump after the back flow device on the incoming water? I have a 2 inch line coming.

Normally I put it in the equipment room right after the line comes into the room
