Pressure-Rated Side Manhole for Operational Practicality
The side manhole positioning allows brewers to access the tank interior laterally without interfering with overhead CIP pipework, upper fittings, or ceiling-mounted systems. This is a significant operational advantage in breweries where ceiling height or overhead equipment limits top-access configurations, and is particularly suited to microbrewery facilities designed with tight vertical clearances.
60° Conical Bottom for Clean and Efficient Yeast Management
The 60° cone angle drives consistent gravitational yeast sedimentation toward the discharge port, enabling clean, controlled yeast harvesting with minimal trub carryover. This supports reliable yeast reuse across multiple production cycles, reducing raw material costs and improving batch-to-batch consistency in commercial brewing operations.
4.5 m² Glycol Jacket — Full-Column Thermal Coverage
With 4.5 m² of dimple plate glycol jacket area applied across both the conical base and the cylindrical sidewall, this fermenter maintains uniform temperature distribution throughout the full fermentation column. At the 1500L scale, consistent thermal management is critical for producing stable ale and lager profiles at commercial output volumes.
360° CIP Rotating Spray Ball — No Disassembly Required
The TC-connected CIP arm with a 360° rotating spray ball delivers cleaning solution to the complete internal surface area, including the dome, manhole area, sidewall, and cone. This enables fully in-place cleaning between batches without tank disassembly, reducing downtime and supporting consistent sanitation standards across multi-tank brewery operations.
100% TIG Welded Construction, Ra ≤ 0.6 μm Interior Polish
All welds are completed under pure argon gas shielding and subject to full inspection. The interior surface is polished to Ra ≤ 0.6 μm with no dead corners, meeting food-grade hygiene requirements for commercial beer production environments. The Pickled and Passivated finish resists corrosion and maintains long-term surface integrity.
Factory Pressure Tested and Fully Documented Before Delivery
Each ZR BREW fermenter undergoes a multi-stage quality verification process including jacket water and gas leak testing (30 psi for 1 hour; 3.6 bar / 37.5 psi for 40 hours), interior polishing verification, and complete system commissioning at the factory. All test data and inspection records are documented and supplied with the unit as part of ZR BREW’s standard quality assurance package.
