Summary for turco agitation Discussion
Turco agitation is the main concern in this thread: Spencer G. says his facility uses Turco 4316-L at 270 °F in an insulated stainless steel tank, but the current teflon-lined recirculation pump can leave the solution at risk of solidifying inside the pump during power failures, which has already happened twice. He asks for a better way to agitate the solution, even if that means changing the tank. Geoff Smith suggests considering an air-operated pump so a compressed-air reservoir could keep the solution moving during an outage. The discussion is brief and offers one practical idea rather than a proven final fix, but the key takeaway is to use a method that maintains agitation when electrical power is lost.

Q. We currently use Turco 4316-L at our facility, and we need a better way to agitate the solution. It is currently pumped through a teflon-lined pump and then recirculated back into the tank. Whenever there is a power failure there is a risk of the Turco solidifying inside the pump (happened twice).
The Turco is maintained at 270 degrees F in an insulated stainless steel tank. I’m looking to find the best way to agitate Turco, so I’ll change the tank if I must.
Thanks…

A. Hi Spencer. Is there any chance of using an air-operated pump so that a compressed air reservoir will keep the solution agitated across a power failure?

A. Good day Spencer.
How about using a pneumatic mechanical mixer, such as used in waste treatment as tank mixing/circulation,with an impeller sized to suit your needs.
These mixers usually require 7-15 degrees incline for maximum solution circulation.
Hope this helps.

A. Hi Spencer
As I recall 4316-L is supplied in liquid form. Therefore it should not solidify at room temperature. Could it be that someone is not making good the evaporation losses? I would suggest that you take a look at your control procedures. Check the data sheet or speak to Henkel.
PS Read and heed the data sheet warnings before adding water.
