Heat transfer fluid for hot condenser tek?

Dynalene PG-XT seems like it will work for this application and is cheap enough. Thoughts? Anyone else use this? Other recommendations?

Will be using with a Polyscience AD7LR-20 heater/chiller circulator

I use thermoltek HTF

Edit: switched to dynalene HC-50 it works just as well.

O ya I saw tht lol what can ya do

Let me see what my buddy charges at his store for the duratherm s

I used polytherm from polysci but it became too viscous at lower temps (10c) and wouldnt pump through my Huber. It worked great at 190-200 but not so good cold so keep that in mind

Depending on how hardcore you want to get… Dowtherm T-66 is one of the most stable heat transfer fluids on the market and is rated for temps well in excess of anything we’d use in our industry.
