K40 2V Brewing System – 46L Two-Vessel Stainless Brewhouse

46L Two-Vessel Brewing System.

46L stainless architecture. 3.5kW heating. Dual pump routing.

Designed operating range

• Nominal vessel capacity: 46 L
• Recommended batch size (into fermenter): 30–38 L
• Maximum practical knockout volume: ~42 L
• Minimum efficient batch size: ~20–25 L

The system performs most consistently in the 30–38 L range, where heating dynamics and liquid geometry remain stable.

Grain load & mash performance

• Recommended grain bill: 8–12 kg
• High gravity practical maximum: ~14 kg
• Recommended mash thickness: 2.5–3.2 L/kg
• Filtration: Laser-cut stainless false bottom (K40)

Example: 10 kg grain at 2.8 L/kg → approx. 28 L mash volume.
Stable recirculation achievable with dual magnetic pumps.

Heating performance

• 1 × 3.5 kW tri-clamp heating element
• 1 × Inkbird C236T (16A EU plug)

Requires one independent 16A electrical circuit.

Estimated heat-up time (35 L water, 15°C → 100°C):
≈ 25–35 minutes depending on ambient temperature.

Boil performance at 30–38 L:
Rolling boil achievable. Evaporation depends on environment and boil intensity.

Hydraulics & flow

• Pumps: 2 × Magnetic pump R15
• Architecture: Sanitary 1.5" tri-clamp routing
• Quick connect system: 11 × 1.5" TC 1/2" quick connect fittings
• Routing hardware: Stainless manifold + tees + valves

Dual pump routing enables:

• Mash recirculation
• Transfer between vessels
• Whirlpool preparation
• Cleaning recirculation through sanitary TC ports

Cooling performance

• Counterflow wort chiller (single-pass)

At groundwater temperature 10–15°C:
Single-pass cooling to fermentation temperature is achievable with controlled flow rate.

Knockout time (35 L): typically within minutes, depending on water pressure and delta-T.

Cleaning & CIP

• CIP-ready: Lid port allows installation of a CIP spray head
• Sanitary TC architecture: All ports serviceable and accessible

System supports recirculation cleaning through the process loop. For higher-flow CIP performance, use a dedicated CIP-capable pump configuration via quick-connect routing.

Power & installation requirements

• 1 × 16A electrical circuit
• Stable water supply for counterflow chiller
• Flat, load-bearing surface

Technical summary

• System type: Two-vessel (Mash + Boil)
• Nominal vessel volume: 46 L
• Working batch range: 30–38 L
• Total heating power: 3.5 kW
• Pumps: 2 × Magnetic pump R15
• Cooling: Counterflow, single-pass
• Architecture: Full stainless tri-clamp
• Material: SS304

Example batch + brewhouse efficiency

Target beer: 12°P Pale Ale / APA (≈1.048 OG)

Target volume into fermenter: 35 L

Base malts typically provide ~80% extract potential (dry basis). Brewhouse efficiency depends on crush, lautering and sparge control.

Calculation

• Wort mass: 35 L × 1.048 ≈ 36.7 kg
• Extract in wort: 12% of 36.7 kg ≈ 4.40 kg

Implied efficiency by grain bill

• 8 kg malt: 6.4 kg potential → ≈ 69%
• 9 kg malt: 7.2 kg potential → ≈ 61%
• 10 kg malt: 8.0 kg potential → ≈ 55%

Realistic brewhouse efficiency: 65–75% depending on process control.
