This is some really good info Quark. Thanks
In response to your question. They have a BAC cooling tower. They are not spraying the EG into the tower. From what I can tell, as they test the water every month, they add more glycol as needed. They ran this system for several years with no rust...
Absolutely positive. I couldn't believe it either. They only have a closed loop when they shut the tower down in the winter and run the system through the boiler.
Thanks for the info Quark.
The building has water source heat pumps. They are using glycol in the condenser water for freeze protection I am assuming.
I have only seen this done if they are using a heat exchanger and using the glycol in a closed loop system
They do have a boiler that they...
I visited a site in Oregon and have a couple of questions. The design uses sch. 80 PVC in the upper floors of the building and black pipe in the basement.
The units in the building are water source heat pumps.
The engineer called for 50% glycol in the system. I am not sure if a rust inhibitor...
