THE ESSENTIAL SECOND STEP IN SPRAYER WINTERIZATION

Ensuring your Apache Sprayer is thoroughly cleaned and free of any chemical residue is a major part of winterizing your machine. But, that’s just half of the equation when it comes to making sure your sprayer is ready for winter. Once all systems are free of chemical, it’s important to add antifreeze to prevent any damage ice can cause in tanks, hoses, nozzles and other components that can lead to headaches for the operator during the application season next year.

 

The first step in this process is to gather the appropriate quantity of antifreeze in manageable containers. The average application system will require 30-40 gallons of antifreeze for the product tank, around 10-12 gallons for the rinse tank and 2-3 gallons for the eductor tank. The containers you’re using will dictate where you will add the antifreeze to the product tank system; if you’re using 1 or 5 gallon jugs, you’ll add the antifreeze to the top of the tank. For a bulk system, it will be added via an attachment to the valve on the side of the product tank.

 

Even though they are all ultimately connected, each circuit – product, eductor and rinse tank – should be individually rinsed and filled with antifreeze when winterizing the machine. It’s important to watch closely to make sure you’re running enough antifreeze through each system to ensure cleanliness and winter preparedness, according to Apache Sprayers Senior Application Specialist John Casebolt.

 

“I want to set up PWM to 100 percent, that way I’m producing all the flow it can produce in order to get flow through the product system through the ball valves and out the nozzle control valves,” he said. “I want to switch my nozzle PWM to 100 percent, then go to manual mode, turn on my master spray switch, then I’ll turn the boom sections on one at a time. I will watch my booms spray until I’m satisfied with a solid, consistent spray of antifreeze fluid coming from the nozzles. Once I’ve done that, I can then move on to the second section and so on.”

 

Casebolt recommended allowing at least two minutes of spray time for each boom section to enable enough antifreeze to move through and remove any water or chemical remaining in the tanks and booms.

 

Each circuit includes different functions important to address in winterizing your sprayer. For example, the product circuit features an agitation function, and it’s important to engage it in flushing the system with antifreeze.

 

“Since we’ll have the product pump running on the machine when winterizing it, I’ll turn on the main sump valve so it’s not running dry,” Casebolt said. “I’ll turn my Rotorflush valve to agitation, then turn on my product pump and it will begin running and moving product through. Then I’ll open up my agitation valve, so I can begin to get that antifreeze flowing through that valve and the tank and agitation tubing. I’ll allow it to circulate for two or three minutes — enough time to get any remaining water purged out, flushed into the tank and have that agitation circuit completely full of antifreeze.”

 

The same is true with the machine’s Rotorflush circuit as well as the chemical eductor circuit. Each has unique components that are essential to address in making sure you’re adequately winterizing your Apache Sprayer.

 

Once your sprayer is adequately cleaned and has the necessary antifreeze to prevent damage from freezing temperatures over the winter, it’s time to turn your attention to other components that can be damaged during the winter.
