I was curious if anyone in Oklahoma / Texas/ Kansas just disables foam brush when the temperature gets to freezing. Our wash was built (not by us) with no freeze protect system for foam brush. We currently use a methanol mix to purge with through the cold spells, but have to monitor it constantly and inevitably someone comes through the middle of the night and freezes one up. We’ve considered a PLC to handle this but seems simpler to just have them auto purge and disable at 32 degrees. We have also used the methanol soap but are constantly switching it because we are warm / cold almost daily
thanks
