I too recommend @Buckeye_Hydro. Contact him with your needs and he’ll suggest a solution for you.
Mine is mounted downstairs, the typical 100 gpd unit. I have the drinking water add-on kit and permeate pump. My system has a split output, with one side connected to the pressure tank which routes out to our fridge ice maker and a drinking faucet I installed at our kitchen sink. The other output is not connected to the pressure tank and is for filling tanks for brewing water. Currently I’ve only done 5 gallon extract kits so I just fill a 7 gallon water cube using a timer to remind me to come shut the system off (100 gpd ≈ 4 gph). I just ordered an Anvil foundry so I’ll probably go to my initial plan of a float valve in a pair of linked 7 gallon water cubes for collecting.
A float valve is a lot cheaper than a pressure tank. Just need to remember to turn it on ahead of time. The system will run until the float valve shuts it off for you. In the meantime the small pressure tank will provide you with a decent amount of drinking water (the pressure tank can’t refill if the float valve is open).
I’ve seen these faucets installed completely unfiltered simply to provide unsoftened water for drinking when the kitchen sink has soft water. Some people just have simple carbon filters to improve taste.
Bottom line though is no pressure tank means it’s almost certainly not RO.

I suspect more of these faucets are not RO vs ones that are RO, because RO systems are expensive and people are cheap. Also as stated some people do not like the taste of RO water.Besides work, I've run into other kitchens with the drinking water faucet on the side. Those may or may not be RO then I guess. Maybe we have a pressure tank though, I will check next opportunity and see.
