Draft Beer Tap Towers, Faucets, and Components Guide

Draft Beer System Diagram

What Is a Regulator?

A regulator is an essential component of any draft beer system, as it plays a crucial role in maintaining the proper pressure and flow of CO2 or nitrogen gas to the keg. This ensures that the beer is dispensed at the correct carbonation level, temperature, and pressure for optimal taste and appearance.

The primary function of a regulator is to reduce the high pressure of the gas coming from the tank to a consistent and manageable level suitable for dispensing beer. This is achieved through a series of internal mechanisms that control the gas flow and pressure output. Regulators typically have a pressure gauge that allows the operator to monitor and adjust the pressure as needed.

Primary Regulatory vs Secondary Regulator

Primary regulators are typically installed at the gas source, such as a CO2 tank, and are responsible for regulating the overall pressure of the gas being delivered to the system. They are essential for maintaining a consistent pressure level throughout the system, which is crucial for ensuring proper carbonation and dispensing of the beer. Primary regulators are adjustable and allow you to set the desired pressure for your specific beer serving requirements.

On the other hand, secondary regulators are installed downstream from the primary regulator and are used to control the pressure of individual kegs or groups of kegs. This allows you to have different pressure settings for different types of beers, which is particularly useful when serving beers that require different carbonation levels. Secondary regulators give you the flexibility to customize the pressure for each keg, ensuring that each beer is dispensed at the optimal carbonation level.

Types of Regulator Gauges

When it comes to setting up a draft beer system, having the right regulator gauge is essential for maintaining proper pressure and ensuring a consistent pour. There are two main types of regulator gauges commonly used in commercial draft beer systems: single gauge and double gauge.

What Is a Distributor?

Distributors are similar to secondary regulators in that they connect to the primary regulator to supply pressure to various kegs. They are also not bound to a gas tank and can be mounted in a more convenient location like secondary regulators.

The key difference between them is that distributors provide no way of regulating pressure, so while they do have individual shut-off valves for each keg, they don't have a gauge and must be used on kegs requiring the same pressure. Using a distributor on kegs requiring different pressure would mean one or more of the kegs isn't getting the ideal amount of CO2, which can lead to several other problems when trying to maintain your beer system.

What Is a Tap Tower?

Also known as draft beer towers or draft arms, beer tap towers are mounted on top of a counter or kegerator and are responsible for not only containing the beer lines but also holding the beer faucets in place. They can range from single faucet towers for smaller establishments to multiple faucet towers for high-volume bars and restaurants. The number of faucets on a tap tower determines how many different beer varieties can be served simultaneously.

In addition to their functionality, tap towers also contribute to the overall presentation of the bar. They are often a focal point for customers and can be customized with different finishes, such as chrome or brass, to match the decor of the establishment.

Tap Tower Considerations

When selecting a draft beer tap tower for your establishment, there are several key considerations to keep in mind for optimal performance and functionality:

1. How Many Kegs Are Dispensing?

The number of kegs directly impacts the size and configuration of the tap tower you will need. If you plan to dispense multiple kegs simultaneously, you will require a tap tower with multiple faucets to accommodate the volume of beer being dispensed.

2. What Size Column Is Needed?

The column size refers to the height of the tower, which can vary depending on the specific needs of your establishment. Taller tap towers are often preferred for larger kegerators or bar setups where a significant amount of beer is being dispensed regularly. On the other hand, shorter tap towers are more suitable for compact spaces or setups with limited headroom.

This is most important if you're purchasing a draft beer tower as a replacement for a worn or broken unit. Because the cutout has already been made in your counter or kegerator, you'll want a tower that has a column of a matching diameter.

Types of Draft Beer Faucets

When it comes to serving draft beer, the type of faucet you choose can significantly impact the pouring process and the overall quality of the beer. Different types of draft beer faucets are designed to cater to specific beer styles and serving preferences.

• Standard Faucet - The most common type of faucet used in draft beer systems, the standard faucet is versatile and suitable for serving a wide range of beer styles. It features a simple design with a lever for easy pouring.
• Creamer Faucet - Ideal for serving cream ales and other nitrogenated beers, creamer faucets are designed to produce a creamy head on the beer. These faucets have a special mechanism that allows the beer to flow smoothly, creating a rich and velvety texture.
• Stout Faucet - Specifically designed for serving stouts and other nitrogenated beers, stout faucets are equipped with a restrictor plate that helps create a cascading effect when pouring the beer. This results in a thick, creamy head that enhances the drinking experience.
• European Faucet - Commonly used in European-style beer dispensing systems, European faucets have a sleek and elegant design that adds a touch of sophistication to any bar or pub. These faucets are often used for serving lagers, pilsners, and other continental beer styles.
• Wine Faucet - For establishments that serve both beer and wine on tap, wine faucets are a practical choice. These faucets are designed to handle the unique requirements of wine dispensing, such as maintaining the wine's aroma and flavor integrity.
• Growler Filler - Perfect for filling growlers with fresh draft beer, growler filler faucets are equipped with a special attachment that allows for easy and mess-free filling. These faucets help maintain the beer's carbonation levels while providing a convenient way to take draft beer to go.

Draft Beer Faucet Finishes

Draft beer faucets are not only functional components of a draft beer system but also add aesthetic appeal to the overall presentation. The finish of a draft beer faucet plays a crucial role in the appearance and durability of the faucet.

• Brass Finish - Brass finish faucets add a touch of elegance to any bar or restaurant setting. They are known for their corrosion resistance and long-lasting performance, making them a reliable option for commercial use.
• Stainless Steel Finish - The sleek and modern look of stainless steel faucets complements various bar designs and themes. Stainless steel finish faucets are also resistant to rust and corrosion, ensuring longevity and performance in a busy bar environment.
• Chrome Finish - Chrome plated faucets are not only stylish but also easy to maintain and clean. The durable chrome finish provides a protective layer that helps prevent tarnishing and scratching, ensuring that the faucet maintains its luster over time.

Draft Beer System Accessories

Draft beer systems require various accessories and components to ensure smooth operation and maintain quality standards. These accessories play a crucial role in keeping the beer lines clean, preventing contamination, and securing the system.

• Keg Racks - Keg racks are sturdy and reliable storage solutions for keeping kegs organized and easily accessible. These racks are designed to support multiple kegs, allowing for efficient use of space and convenient keg rotation.
