Gurus,
My 120V compressor is located in the bay below passenger seat. It is a "standard" setup for this vintage coach. There is a little solenoid that releases air pressure to the pump when the pump cycles off. The air line then goes to a "spitter" to remove the water and then to a T that feeds the wet tank and also gets routed to the pressure switch.
Even though I drain the spitter and the tank on a regular basis, water can get into the pressure relief solenoid body. When it gets cold, the water freezes and chaos ensues. I have had the solenoid fail badly which resulted in huge air leak. Last week during cold weather, it froze up but did not fail.
Remember this solenoid is the first thing that the airline gets to after the pump.
I have come up with two solutions...and would like to hear your thinking.
1) Put a dryer / spitter right after the pump. The idea is to get rid of water before it gets to the solenoid.
2) Add an electric heater similar to the one in the AH bay to keep the temperature of the bay above freezing.
Has anyone made modifications to their air system to keep the ice out?
