300L Top Manhole Fermenter

SUS304 Stainless Steel Glycol Jacketed Cooling Pressure Top Manhole Design

Product Description:

The ZR BREW 300L beer fermentation tank is a compact, commercial-grade conical unitank purpose-built for nano breweries, pilot brewing programs, and growing microbrewery operations. Featuring a pressure-rated top manhole design that allows convenient access for dry hopping, cleaning, and inspection, this fermenter is fabricated from certified SUS304 stainless steel with a fully insulated glycol cooling jacket for precise fermentation temperature control. It is designed for B2B buyers who require a reliable, sanitary-grade fermentation vessel with the flexibility to customize tank configuration, fittings, and finish level to their specific facility and process requirements.

Advantage of Configuration

Pressure-Rated Top Manhole for Versatile Access
The top manhole design provides direct overhead access for dry hopping, fining agent addition, internal inspection, and manual cleaning when required. This is particularly practical for nano brewery teams managing compact batches with frequent recipe adjustments.

60° Cone for Clean and Complete Yeast Discharge
The 60° conical bottom ensures efficient gravitational yeast settling and clean harvest from the discharge port. This minimises cross-batch contamination risk and supports consistent yeast reuse across multiple production cycles.

Full-Coverage Glycol Jacket — Cone and Sidewall
Dimple plate glycol jackets are applied to both the cone section and the cylindrical sidewall, providing full-column temperature uniformity. This level of thermal control is essential for maintaining consistent fermentation profiles in both ales and lagers at the 3HL scale.

360° CIP Spray Ball — In-Place Cleaning Without Disassembly
The TC-connected CIP arm with a 360° rotating spray ball ensures complete internal surface coverage during cleaning cycles. Breweries with limited staff benefit from reduced manual cleaning time and consistent hygiene results between batches.

100% TIG Welded, Ra ≤ 0.4 μm Interior Polish
All welds are performed under pure argon gas shielding and fully inspected. The interior surface is polished to Ra ≤ 0.4 μm with no dead corners, meeting food-grade sanitary requirements for commercial beer fermentation environments.

Factory Pressure Tested and Documented Before Delivery
Each tank is water and gas jacket leak tested (30 psi for 1 hour and 3.6 bar / 37.5 psi for 40 hours) at the ZR BREW facility. All test records are documented and shipped with the unit as standard quality assurance documentation.

Frequently Asked Questions

  • Is the 300L beer fermentation tank suitable for a nano brewery or pilot brewing operation?

    Yes. The 300L beer fermentation tank (approximately 3HL or 2.56 BBL) is specifically well-suited for nano breweries, pilot brewing programs, and small-batch commercial operations. It is designed to the same sanitary and pressure standards as larger commercial units, making it suitable for both recipe development and regular production at the nano scale. Buyers who plan to scale up can also add additional tanks from the same ZR-FV series for expanded capacity.

  • What makes the top manhole design practical for small brewery operations?

    The pressure-rated top manhole on this fermenter allows direct access to the tank interior from above, which is particularly convenient for dry hopping, adding fining agents, performing visual inspections, or completing manual interior checks. For nano brewery teams that frequently adjust recipes or work with specialty ingredients, this access point reduces the need for additional equipment compared to side manhole configurations.

  • Can the fermenter configuration be customized to match my facility layout?

    Yes. ZR BREW manufactures all fermenters to order. Buyers can request adjustments to leg height, fitting positions, manhole type, interior finish level (2B, pickled and passivated, or mirror finish), insulation thickness, and cooling jacket coverage. 2D and 3D facility layout drawings are available to help align the final tank specification with your floor plan and ceiling constraints.

  • What cooling infrastructure does this fermenter require?

    This fermenter uses a glycol water cooling system connected to the dimple plate jacket on both the cone and sidewall. A separate glycol chiller or cooling unit must be supplied at the appropriate flow rate and glycol temperature for your target fermentation temperature range. ZR BREW can supply matched glycol cooling systems sized for single-tank or multi-tank setups. Contact our team for a cooling system recommendation based on your total installed fermentation volume.

  • How is the interior cleaned between batches, and does it require manual disassembly?

    No manual disassembly is required for standard cleaning cycles. The fermenter is equipped with a TC-connected CIP arm and a 360° rotating spray ball that delivers cleaning solution across the full internal surface area, including the top dome, sidewall, and cone. The Ra ≤ 0.4 μm mirror-polished interior with no dead corners ensures that cleaning solution reaches all surfaces without pooling or retention. The unit is designed to connect directly to a mobile CIP cart or fixed CIP system.
