Hello All!
We have a steam humidifier on our home. (Basically is is a tank with water that boils. The air handler picks up the steam and sends it into the mini duct system we have for air conditioning. White Rodgers HSP model) It has two safety floats whose job is to stop the heater if the water is too low or too high. They are float balls on stainless steel arms. (Photo attached)
Our problem is that, despite the lime filter on the water inlet line, the float arms get lime coated in short order. When the are coated, the balls stick.
I've tried coating the arms & inside the float sleeves to try to keep the lime from sticking. Anything I've tried washed off due to the hot water in which they live.
Here's What I've Tried:
Automotive mineral oil
Automotive synthetic oil
Differential grease
Hydraulic oil
HyPer Lube paste
Car Wax
Bees Wax
Moly Bearing Grease
Synco Super Lube
Petroleum Jelly
Teflon Sleeve over the arms
Hoping to use something I have in the shop, I thought about Never-Seez type anti seize paste. I have copper & silver available. My other thought was white lithium grease.
Do you all think one of those would work? If not, do you have any ideas of what to use?
Thank You for helping our and for educating! I appreciate your knowledge sharing.
Enjoy This Day,
Paul
