Kegco 33 Cu. Ft. Nitrogen Air Tank – High Pressure Aluminum Gas Cylinder
The Kegco 33 Cu. Ft. nitrogen tank combines high-pressure capability with a lightweight design. Built from 6061-T6 aluminum alloy, this cylinder is corrosion resistant and easy to handle, ideal for both home brewers and small cafes. It supports service pressures up to 2216 PSI (153 BAR) and comes hydrostatically tested to 3694 PSI (254.7 BAR) for dependable long-term use. A premium protective finish adds extra resistance to scratches and wear, helping the tank maintain a professional appearance over time. This tank is suitable for nitro coffee applications that require steady, high-volume dispensing.
Practical notes: its aluminum body reduces weight compared with steel, easing transport and setup. The robust coating helps preserve the appearance in high-traffic kitchen or bar areas. If you’re upgrading from smaller cartridges or upgrading a home nitro system, this tank offers headroom for larger batches and faster pours without frequent recharges.
Kegco 22 Cu. Ft. Nitrogen Air Tank – High Pressure Aluminum Gas Cylinder
Compact yet capable, the Kegco 22 Cu. Ft. nitrogen tank provides a balanced solution for home setups and compact commercial spaces. Like its larger sibling, this cylinder uses high-strength 6061-T6 aluminum alloy to deliver rust-free performance and easier handling. It’s engineered to handle up to 2216 PSI (153 BAR) service pressure and is hydrostatically tested to 3694 PSI (254.7 BAR) for durability under demanding dispensing conditions. The black epoxy protective finish adds a sleek, professional look while providing additional resistance to wear, corrosion, and scratches.
Ideal for smaller kegs or when counter space is limited, this tank enables more manageable nitrogen storage without sacrificing the reliability needed for nitro coffee or nitro beer applications. Consistent nitrogen delivery supports smooth cascades and a creamy mouthfeel in every glass.
RedRock 18g Nitrogen Cartridges – 2 Pack (Threaded 5/8″)
While not a tank, these 18-gram nitrogen cartridges are a common companion for nitro systems, delivering a full charge for many infuser setups. They feature a high-purity, food-grade nitrogen (99.5%) with a threaded 5/8″ neck for a leak-free connection. Designed for compatibility with most nitro infusion systems and mini keg regulators, these cartridges offer a convenient option for smaller batches or quick nitro infusions. They’re housed in recyclable steel, aligning with eco-conscious usage. Each cartridge provides a reliable, mess-free way to inject nitro into beverages without sacrificing flavor integrity.
Consider cartridges as a modular option for smaller volumes or as a backup for larger tanks. They’re particularly useful if you want to occasionally run a nitro batch without committing to frequent cylinder exchanges.
Beverage Elements Nitro Coffee Cold Brew Kit – 5 Gallon Keg
This kit provides a complete nitro coffee solution designed for higher-volume dispensing. It includes a new stainless steel 5-gallon keg with handle, a 40 cu ft nitrogen tank, and a high-quality Taprite dual-gauge regulator. The combination is aimed at home enthusiasts seeking a turnkey system that can support frequent nitro pours with minimal setup complexity. The stainless keg ensures durability and sanitation across repeated use, while the regulator helps maintain precise pressure control for consistent head formation and pour quality.
Key considerations include the compatibility of the regulator with your nitrogen source and the ability to sustain long pours without gas loss. This setup is well-suited for entertaining, small offices, or weekend nitro coffee enthusiasts who want a reliable, all-in-one solution.
Magula 3L Liquid Nitrogen Dewar
The Magula 3L dewar focuses on liquid nitrogen storage rather than a traditional high-pressure gas cylinder. While not a nitro tank for dispensing, it serves critical roles in fueling cryogenic storage needs, sample preservation, and other laboratory or culinary applications. The design uses aerospace-grade aluminum, contributing to durability and slower evaporation rates. Its compact form factor makes it suitable for spaces where a larger cylinder is impractical. If your nitro setup involves liquid nitrogen storage in addition to gas delivery, this can complement your system by providing a reliable reservoir for LN2.
New 20 Cubic Foot Steel Nitrogen Cylinder
This steel nitrogen cylinder from Gancowise offers DOT approval and robust construction for industrial or heavy-duty use. With a CGA-580 valve, it aligns with standard nitrogen regulators widely used in commercial nitro setups. While steel cylinders can be heavier than aluminum, they’re valued for ruggedness and long service life in demanding environments. The cylinder ships empty, so you’ll need to arrange refilling locally. It suits users who require a high-capacity, durable tank for frequent nitro beverage production or large-volume events.
U.S. Solid 30L Cryogenic LN2 Tank Dewar
This 30-liter LN2 tank is designed to hold liquid nitrogen for specialized applications requiring very low temperatures. It’s marketed for professional settings, with practical uses in research, medical, and industrial contexts. For nitro coffee enthusiasts, it’s more relevant as part of a larger, multi-use cold storage strategy rather than a primary nitro beverage dispensing system. The dewars are built to maintain cryogenic temperatures with appropriate insulation and hardware to support safe handling and transport. If your workflow includes cryogenic storage alongside nitro beverage production, this tank can be a valuable asset.
Beverage Elements Nitro Coffee 3 Gallon Kit
This kit provides a smaller, more portable nitro coffee option. The 3-gallon cylinder and accompanying keg aim to deliver a compact, scalable nitro experience for homes or small gatherings. It includes critical safety and pressure-relief features, with a CGA580 valve and an emphasis on food-safe construction. This setup is well-suited for enthusiasts who want to experiment with nitro coffee in smaller batches or who lack space for larger tanks. The included components simplify setup and help ensure consistent pours at a modest scale.
Buying Guide: Key Purchase Considerations
- Tank capacity and space: Larger tanks offer more nitro for frequent dispensing but require more space and heavier handling. Smaller tanks fit cramped kitchens or offices but may need more frequent refills.
- Material and durability: Aluminum tanks are lighter and corrosion resistant, while steel cylinders are typically tougher and suited for industrial use. Consider your environment and handling needs.
- Pressure rating and regulator compatibility: Look for high service pressures (at least 2000–2200 PSI) and ensure regulators use standard CGA-580 connections or compatible fittings for your setup.
- Liquid nitrogen vs. gas cylinder: If your workflow relies on LN2 storage, consider dewar options in addition to gas cylinders. For nitro coffee pours, gas cylinders with appropriate regulators are typically sufficient.
- Safety and compliance: Ensure DOT or relevant safety certifications are met for the chosen tank, especially for transport and storage. Empty ships require local refilling arrangements.
- System completeness: Some kits include regulators, kegs, and accessories, offering a turnkey solution. Assess whether you need just a tank or a full nitro system with compatible parts.
- Cost of ownership: Factor in refills, local availability, and potential need for adapters or conversion kits to maximize long-term value.
Overall, the best nitrogen tank for cold brew depends on your batch size, space, and how often you’ll dispense nitro coffee. Aluminum tanks provide portability for home use, while steel options serve heavier, ongoing commercial needs. Kits that combine tanks, regulators, and kegs can simplify setup and deliver reliable, repeatable nitro pours for a wide range of environments.
