6.7 m² Glycol Dimple Plate Jacket — Full-Column Thermal Precision at 30HL Scale
With 6.7 m² of glycol jacket area applied across both the conical base and the cylindrical sidewall, this fermenter delivers uniform temperature control throughout the entire 3000L liquid column. At commercial scale, this level of thermal coverage is essential for maintaining consistent fermentation profiles and producing stable ale and lager batches across high-frequency production cycles.
100 mm Polyurethane Insulation — Reduced Glycol Load and Stable Temperature Hold
The ZR-FV-3000 features an upgraded 100 mm polyurethane insulation layer, compared to the 80 mm standard used on smaller models in the range. This thicker insulation layer reduces heat transfer losses, lowers the workload on the glycol cooling system, and maintains fermentation temperature stability over extended conditioning periods — a significant operational advantage for commercial breweries running multiple tanks simultaneously.
60° Conical Bottom — Efficient Yeast Harvest for High-Volume Operations
The 60° cone angle drives complete gravitational yeast sedimentation and clean trub separation in tanks of this volume. At the 3000L commercial scale, reliable yeast harvesting directly reduces raw material costs, improves batch-to-batch yeast reuse consistency, and supports tighter production scheduling across a multi-tank brewery floor.
Pressure-Rated Side Manhole — Accessible at Scale
The side manhole design allows brewery operators to access the tank interior at a practical working height without requiring elevated platforms or overhead clearance, particularly useful when multiple 3000L units are arranged in rows on a commercial brewery floor. This access point supports dry hopping, inspection, and maintenance operations with minimal process disruption.
360° CIP Rotating Spray Ball — Full Hygiene Coverage, No Disassembly
The TC-connected CIP arm with a 360° rotating spray ball delivers cleaning solution across the full internal surface area of the 3000L vessel, including the dome, side manhole zone, sidewall, and cone. This is critical for multi-tank commercial operations where consistent sanitation standards must be maintained across high-frequency batch cycles without unplanned cleaning downtime.
Factory Multi-Stage Pressure Testing — Documented Quality Assurance
Every ZR BREW fermenter undergoes a complete factory quality verification sequence: jacket leak testing at 30 psi for 1 hour; 3.6 bar / 37.5 psi water and gas test for 40 hours; interior polish verification to Ra ≤ 0.6 μm; and full system commissioning. All records are documented and delivered with the tank. Complete valves, fittings, and hardware are included in the delivery scope.
