Glycol Colouring
Glycol Colouring
(OP)
We recently have a problem with regards to our propylene glycol solution. The glycol solution is used as a secondary refrigerant for our ammonia refregeration system. The problem is the perenial leaking of glycol solution along pipes, valves or glycol-cooled tanks. We dont have any idea on how to locate leaking glycol solution. Except for the idea of putting a colour in the glycol solution. Can anybody help me what type colouring we need?

Coastal Chemical in Houston is who I've used before.

Here are two other approaches to detect your leaks, it is again the tracer dyes and the colorimetric papers.
I would contact American Gas with your specific problem.
