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.
