Operation
The DX1000 is an automatic microprocessor controlled system
which will drastically reduce water usage in your weep system.
First winter savings averaged 65% in my 5 car washes. It will
also control any secondary function you would like to turn
on or off, depending on temperature, inside or out, such as
switch from cold to hot water for weep, turn on auxiliary
heater, turn on exhaust fan, etc.
The old proven method of using a cheap thermostat to open
your solenoid valve and let the water run worked quite well
most of the time, but it is getting to be very expensive to
let all that water run down the drain, now that most cities
are charging a sewer tax for every gallon of water used. You
have probably never stopped to figure out how much you are
wasting. Most operations normally run a minimum of 1/3 gpm
through the nozzle to keep it from freezing. At this rate
for a normal 6-bay self-service car wash, that would be 2
gallons of water used for every minute the temperature is
below 36 degrees. This may not seem like much, but it comes
up to a whopping 20,160 gallons for 7 days, if the temperature
stays below 36 degrees. My cost per 1,000 gallons, water and
sewer combined, is $3.40. Some cities are less and some are
more, but most are in the $3 to $5 range per 1,000 gallons.
At $3.40 per 1,000 that comes to about $68.00 expense for
every week the weep system runs. You can cut that expense
to *$23.00 by using the DX1000 to control your weep system.
The DX1000 automatically turns your system on when the temperature
falls to 35 degrees, and runs water for 6 seconds. Then it
shuts off for 54 seconds. For every degree the temperature
falls, it automatically stays on approximately 2 seconds longer.
By the time the temperature falls to 15 degrees, it is running
water for 54 seconds and off for 6 seconds. Below 15 degrees,
the water is on continually. The figures above are for the
built-in "FAIL SAFE" program, but you can adjust
to your specifications, if you so desire.
The DX1000 continuously displays the temperature of the
coldest sensor in the circuit and operates the weep accordingly.
You have the option of installed sensors on opposite sides
of the building. If you so desire, to prevent the possibility
of your system shutting down due to the sun reflecting off
the ice and warming the sensor (which has probably happened
and you couldn't figure out why you froze up).
The time has come for all of us in the car wash industry
to do what we can to cut expenses and also to stop wasting
our precious water. There are many things we can all do to
save our resources, and this is but one of them. If we all
observe a little conservation practice, we can hopefully do
our part. We should make sure that when a tank overflows due
to a faulty valve, we fix the valve ASAP, etc.
*Example only, Cost savings will vary.
