Hey IC...Couple Questions for anyone that uses Pure Propane as solvent and has experience with a proper heat exchange to chiller combination. I am looking to purchase a heat exchanger..And I am currently looking at the Bhogart 100lbs an hour unit...which is probably a tad overkill for my system which is probably more around 50~60lb range..but for the price it seems reasonable...however thats only half the solution. My question is...has anybody used this particular exchanger? If so what chiller did you throw at it to achieve our desired results? In my case as I assume most folks case I'm looking for a recovery time of more or less 1 hour. If anybody has an alternative solution..I'm open to suggestions. Any recommendations appreciated. Thanks!
