Today I want to talk to you about a question we commonly get asked. And that is: why do we use metal handles on our disconnects versus plastic?
For us and our applications, we try to build a robust product that can withstand harsh environments such as South Texas. In South Texas, we have high summer temperatures and high humidity environments. The application oftentimes sits in corrosive environments. Even here on a water well, we have very corrosive hard water, and if that were to splash on to the drive package, having that metal powder-coated handle is going to be beneficial in the long run to withstand any sort of corrosion.
Here you can see; the black powder coat is still holding strong after five years of installation on this well. If you come over here, we have the panel that the drive replaced, it’s a soft start box with a plastic handle.
It didn’t quite handle the South Texas heat. The plastic gets brittle over time and ultimately cracks and this can create, if it were to completely fail, a potential safety hazard. If that handle were to completely fail, you would have to find something else to substitute.
This is one of the benefits to using an all-steel product versus something that may be perceived to be a little cheaper in the short run, but in the long run, you’re going to end up having to spend more.
Hope this helps. I hope you have a great day.
