The BrewTaurus K40 2V is a 48.1 L two-vessel electric brewing system in 304 stainless: K40 mash tun + K40 boil kettle, 3.5 kW of Tri-Clamp heating, two 15R pumps and a counterflow chiller. 20–35 L into the fermenter, up to ~13 kg of grain. Full sanitary Tri-Clamp architecture, no proprietary parts.
| Vessels | K40 mash tun + K40 boil kettle |

| Heating | 3.5 kW — 1× 3.5 kW (boil kettle) |
| Electrical | 230 V · one dedicated, RCD-protected circuit |
| Pumps | 2× 15R — 16 L/min, 2.3 m head at 50 Hz, up to 120 °C |
| Wort chilling | counterflow chiller, single pass |
| Brim-full volume | 48.1 L per vessel |
| Guarantee | 2-year legal guarantee (EU consumer law) |
What's in the system
- K40 mash tun: laser-cut false bottom, 150 × 250 mm grain door with chute
- K40 boil kettle: 1× 2" element port, 45° whirlpool port, centred 1.5" drain
- Heating elements: 1× 3.5 kW (boil kettle)
- Pumps: 2× 15R
- Stainless manifold, tees and valves · 11× 1.5" TC–½" quick-connects
- Counterflow wort chiller, single pass
Not included: heating controllers (see Control below).
Heating & boil
- 1× 3.5 kW (boil kettle) · one dedicated, RCD-protected circuit · heating controllers not included
- Heating pace: ~1.3 °C/min at 35 L — mash-to-boil (72→100 °C) in ≈22 min
- Boil: rolling boil at 30–35 L, ~2–3 L/h boil-off
Grain & gravity
| Grain for 12 °P (OG 1.048) at 35 L | ~7.9 kg |
| Maximum grain bill | ~13 kg |
| Gravity at maximum grain, 35 L | ~18 °P (OG ~1.074) |
Mash thickness 2.4–3.2 L/kg; don't go below 2.3 L/kg. The mash tun takes the grain; the boil kettle sets the batch — so extra grain capacity means stronger beer, not bigger batches.
Hydraulics, cooling & cleaning
- 2× 15R for recirculation, sparge, transfer and whirlpool (16 L/min, 2.3 m head at 50 Hz, up to 120 °C)
- Pumps are not self-priming: mount them below the liquid level and flood the head before starting.
- Counterflow chiller, single pass to 18–22 °C with 10–15 °C mains water.
- CIP: a 1.5" CIP spray head on a 1.5" lid port needs more flow than the 15R gives — use an MP-40RM pump for cleaning in place.
Installation: One dedicated, RCD-protected circuit — have a qualified electrician size and connect the circuits, stable water supply for the chiller, flat, load-bearing surface. Plan the electrical and structural preparation before delivery.
Control: K-Series systems ship without heating controllers. A dedicated BrewTaurus control unit for the K40/K80/K220 is in development and planned for release in spring 2027 — it will connect to the existing elements and pumps without replacing any vessel. Until then, use a third-party controller rated for the full current of each element.

1V vs 2V vs 3V — which K40 configuration
Same vessel size, same batch (20–35 L into the fermenter), three brew days. More vessels mean more grain, parallel steps and no lifting. Your configuration is highlighted.
| Config | Vessels | Max grain | Heating · pumps · chiller |
|---|---|---|---|
| K40 1V | kettle + malt pipe | ~10.5 kg | 3.5 kW · 1× 15R · no chiller |
| K40 2V | mash tun + boil kettle | ~13 kg | 3.5 kW · 2× 15R · counterflow chiller |
| K40 3V | HLT (HERMS coil) + mash tun + boil kettle | ~13 kg | 7 kW · 2× 15R · counterflow chiller |

FAQ
How big a batch can I brew?
20–35 L into the fermenter.
How much grain fits?
About 13 kg. A 12 °P beer at 35 L needs ~7.9 kg; at maximum grain you reach ~18 °P (OG ~1.074).
How do I heat strike and sparge water?
Strike water heats in the boil kettle; pump it across to the mash tun. For sparge water you have two options: brew no-sparge (it works when the whole brewing liquor fits in the mash tun, so smaller or lighter batches), or heat the sparge water in a separate vessel. Tip: use your fermenter. If it has a 2" Tri-Clamp port, fit a 2.2 kW or 3.5 kW element (keep it fully submerged) and heat the sparge water in it — no extra vessel to store, and the hot water sanitises the fermenter before the wort goes in.
What power do I need?
1× 3.5 kW (boil kettle) at 230 V, with one dedicated, RCD-protected circuit. Have a qualified electrician size and connect the circuits. Power control is external.
Does it come with a controller?
No. A dedicated BrewTaurus control unit is planned for release in spring 2027; until then, use a third-party controller rated for the full current of each element.
Product photos may show a prototype or a different size; production units follow the manufacturing drawing.
Gravity figures assume 70 % brewhouse efficiency (65 % at maximum grain); your mill, malt and process will move them.
