The system you buy when all-in-one stops making sense.
The BrewTaurus K40 Boil Kettle is a 48.1 L kettle in 304 stainless, built around Tri-Clamp: one 2" heating-element port, three 1.5" front ports, a 45° whirlpool port and a centred bottom drain. Boil in it, add a malt pipe for single-vessel brewing, or run it as the boil vessel of a two- or three-vessel brewhouse. Nothing here is temporary.

FAQ
What is the real working volume?
48.1 L brim-full. Plan up to ~40 L pre-boil to keep boil-overs away — that gives 20–35 L into the fermenter.
Which heating elements fit?
Any 2" Tri-Clamp element — for example our 2.2 kW or 3.5 kW (230 V). Power control is external (PID + SSR or a power controller), and each element needs its own dedicated, RCD-protected circuit. Our K40 systems run one 3.5 kW element.
Can I brew indoors?
Yes. Swap the flat lid for the Ø350 steam condenser set — it condenses the boil vapour instead of venting it into the room. See the set for its water connection.
Is the HLT the same vessel?
Yes. The K40 HLT uses this body and adds a removable HERMS coil and its fittings.
