Bräu Supply’s DrainPro™ Kettle lineup is engineered for brewers who demand the precision and performance of a true bottom-drain vessel. Built from premium 304 stainless steel, fully welded, and equipped with tri-clamp ports throughout, these kettles provide the cleanest, most efficient, and most modular brewing experience possible — whether you're building a home brewery or scaling up a 1–3 bbl pilot system.
Designed specifically for electric brewing, CIP workflows, and pro-style process control, DrainPro kettles eliminate dead zones, trapped sediment, and the cleaning headaches of traditional side-drain kettles. No threads. No compromises. Just a perfectly sanitary, fully drainable platform ready for any tri-clamp element, pump, or controller.
Why Choose a Bottom-Drain Kettle?
Most “premium” brew kettles rely on a side drain — a design that leaves behind trub piles, wort loss, and sanitation risks. A true bottom drain solves these issues, delivering a fully drainable, fully cleanable, CIP-ready kettle that integrates seamlessly with professional brewing practices.
Bottom-Drain Advantages
- Complete emptying with no tilting
- Minimal wort loss and maximum yield
- Fast, simple CIP cycles
- No dead zones or trapped solids
- Cleaner whirlpool performance
- Optimized for continuous recirculation & step mashing
- Integrates directly with conical fermenters
Key Features of DrainPro™ Brewing Kettles
True Welded 1.5" Tri-Clamp Bottom Drain
A seamless, fully welded 1.5" TC bottom drain ensures complete drainage with zero trapped wort. Perfect for CIP, filtered transfers, and sanitary brewing operations.
Optimized for Electric Brewing & Pilot Systems
Every DrainPro kettle includes welded tri-clamp ports for heating elements, sensors, recirculation, CIP, steam condensation, and professional closed-loop electric brewing setups.
Heavy-Duty Stainless Construction
Featuring the thickest walls in the category, DrainPro kettles offer exceptional thermal stability and long-term durability under continuous recirculation, step mashing, and aggressive boil conditions.
Purpose-Built Port Layouts
Choose from dedicated HLT, Mash, or Boil Kettle configurations — each optimized for its role. Larger models include a hinged grain access door for fast, safe, and simple grain-out.
CIP-Compatible Lid Port
A welded tri-clamp lid port makes it easy to connect a sprayball or steam condenser for fully integrated CIP cleaning.
Fully Tri-Clamp
Sanitary, modular, and fully compatible with professional brewery hardware. No threaded fittings, no hidden bacteria traps.
