That steam condenser is just a collection of TC pipes, fittings and spray nozzle from China. I bought the parts for my own design and saved a fortune. You can't really control the condenser as such. The nozzle is a fixed, in terms of spray, once at working pressure. You'll find the power input is what actually determines the boil-off rate. You need to tweak it to suit your conditions. Determine empirically what works best for your system in your brewing environment, that is. Once boil is reached on my system (Braumeister), I dial down the power to about 40% to get a nice controlled 'simmer' balanced with the condenser for a steam-free boil.You might be able to go lower, because your heating elements are OTT for home brewing, why they're notorious for scorching on the BT B80.
