DRNX by Brood Cold Brew Coffee System - Commercial Nitro Cold Brew Dispenser

On-Demand Nitro Cold Brew System for Coffee Shops, Cafes & Restaurants

The DRNX by Brood commercial cold brew coffee system delivers tap-ready nitro cold brew and cold brew coffee on demand without the complexity, space requirements, and waste of traditional keg-based nitro systems. Engineered by Fetco specifically for specialty coffee shops, cafes, and restaurants, the DRNX system eliminates the need for external nitrogen tanks, keg storage, and complicated draft systems while providing consistent cascading nitro texture and precise serving temperatures for premium cold brew service.

Keg-Free Nitro Cold Brew Technology

No Nitrogen Tanks Required — Integrated nitrogen generation system produces food-grade nitrogen on demand from ambient air. Eliminates the recurring cost, logistics, and storage burden of purchasing, exchanging, and storing compressed nitrogen cylinders—critical advantage for small-footprint cafes and locations where gas cylinder delivery is impractical.

No Kegs, No Waste — Traditional keg-based nitro systems require 5-gallon minimum batches, leading to product waste when kegs oxidize or expire before depletion. DRNX uses bag-in-box concentrate containers, allowing shops to serve fresh nitro cold brew without committing to large batch volumes or managing keg inventory and washing cycles.

Compact Counter Footprint — All-in-one countertop design integrates nitrogen generation, refrigeration, dilution control, and dispensing in a single unit. Eliminates the back-of-house space requirements of traditional draft systems with external nitrogen tanks, keg coolers, and complex plumbing runs.

Instant Nitro Texture — On-demand nitrogen infusion creates the signature cascading effect and creamy mouthfeel associated with premium nitro cold brew. Consistent gas dissolution across every pour maintains texture quality from first cup to last without the pressure drift common in keg-based systems as nitrogen depletes.

Precision Cold Brew Dilution & Temperature Control

Programmable Concentrate-to-Water Ratios — Adjustable dilution control allows cafes to dial in exact concentrate-to-water ratios matching their specific cold brew recipe and desired serving strength. Accommodates different concentrate batch strengths (1:4, 1:5, 1:6 ratios) without reformulating base recipes.

Integrated Refrigeration System — Built-in cooling maintains serving temperature at optimal 38-42°F range. Delivers consistently cold product without relying on ambient ice bins or requiring external cold plate glycol systems.

Dual Dispense Options — Serve both nitro cold brew (nitrogen-infused) and standard cold brew (still, non-carbonated) from the same system. Single equipment platform supports diverse menu offerings without additional dispensing infrastructure.

Operational Efficiency for High-Volume Service

Rapid Dispense Speed — Pour times under 20 seconds for 16oz servings maintain service flow during rush periods. Comparable speed to traditional draft systems without the maintenance overhead of pressurized keg systems.

Minimal Training Required — Single-button operation eliminates barista learning curve associated with managing keg pressures, gas regulators, and troubleshooting draft system issues. New staff can operate system proficiently within minutes.

Easy Cleaning Protocol — Simplified daily cleaning routine compared to traditional draft systems with multiple connection points, gas lines, and keg couplers. Reduces labor time and ensures consistent sanitation compliance.

Bag-in-Box Changeover — Quick-connect concentrate containers swap in under 60 seconds without tools. No heavy keg lifting, CO2 purging, or coupler fumbling during peak service windows.

Menu Applications & Revenue Opportunities

Nitro Cold Brew Program Without Capital Investment — Launch premium nitro cold brew service without the $3,000-$8,000 capital outlay required for traditional keg-based draft systems (nitrogen tanks, regulators, keg coolers, tap towers, installation labor).

Seasonal & Limited Release Flexibility — Small-batch concentrate format allows cafes to rotate seasonal cold brew offerings, single-origin showcases, and experimental infusions without committing to 5-gallon keg minimums.

Customizable Flavor Infusions — Serve house-made concentrate blends with vanilla, cinnamon, orange, or other flavor profiles. Rapid changeover between concentrates enables daily or weekly rotation programs.

Consistent Premium Pricing — Nitro cold brew commands $1.50-$2.50 premium over iced coffee in specialty cafe environments. DRNX system quality matches customer expectations for premium pricing without traditional draft system complexity.

Cost-of-Ownership Advantages vs. Traditional Nitro Systems

No Nitrogen Cylinder Rental or Refill Costs — Traditional systems require recurring nitrogen tank rental fees ($15-$30/month) plus refill costs ($25-$50 per tank exchange). DRNX eliminates this ongoing operational expense entirely.

Reduced Product Waste — Keg-based systems often result in 10-20% product loss due to oxidation, over-ordering to meet 5-gallon minimums, or line purging during cleaning. Bag-in-box format reduces waste to near-zero.

Lower Maintenance Complexity — Traditional draft systems require periodic regulator calibration, gas leak testing, coupler replacement, and tap line deep-cleaning. DRNX simplified design reduces maintenance touch points and service call frequency.

No Keg Washing & Sanitizing Labor — Eliminates the back-of-house labor burden of keg washing, sanitizing, and inventory rotation required in traditional draft cold brew operations.
