Question about 50L rotary evaporator real capacity

Hi everyone, I came across a 50L rotary evaporator on a supplier’s website and I’m wondering if anyone here has experience with this kind of setup. We need to evaporate about 20 L/h of water, but the feed is a concentrated brine (2–5M Cl). I know the salt content will reduce the effective capacity, but I’m not sure by how much. So I have a few questions: What’s the typical evaporation capacity (L/h) for water at 100% power on a 50L unit? With brine, how much reduction should I expect? Around 10%, or could it be as high as 50%? Would really appreciate if anyone with hands-on experience could share some insights. Thanks a lot!
