Long Draw Draft System: Essential Tips for Optimal Performance

A long draw draft system, also known as a glycol-cooled system, is an essential component for many bars, restaurants, and other facilities that serve draft beer. This powerful beer system is designed to keep beer fresh and cold from the keg to the faucet, ensuring an enjoyable experience for customers. By allowing businesses to store kegs in walk-in coolers away from the bar area, this system offers efficiency and convenience for both staff and patrons.

There are two primary methods for cooling the beer in a long-draw draft system: air-cooled and glycol-cooled. The air-cooled systems use a forced air blower to send cold air from the cooler through a conduit enclosing the draft lines, helping to keep the beer at a consistent temperature. On the other hand, a glycol-cooled system uses a liquid glycol solution to maintain the ideal temperature for beer as it travels in chilled air through insulated lines from the keg to the faucet.

Implementing a proper long draw draft system requires careful planning and attention to detail. Businesses must consider factors such as the distance between the kegs and faucets, the desired temperature, and the specific components needed to achieve a reliable, well-functioning system. By doing so, establishments can consistently deliver cold and refreshing beer to their customers, enhancing the overall experience and enjoyment.

Understanding Long Draw Draft Systems

Long draw draft systems are designed to deliver draft beer over long distances, maintaining its quality and temperature throughout the entire line. These long-draw beer systems are commonly found in bars and restaurants where kegs are stored far away from the faucets. They use a combination of pressure, resistance, and temperature to ensure a consistent flow of beer from the keg to the tap, providing customers with a fresh and delicious drink.

Elements of a Remote Draft System

There are two main types of long draw draft systems: glycol-cooled and air-cooled. Glycol-cooled systems utilize a glycol chiller that pumps a mixture of glycol and water through a trunk line, keeping the beer at a consistent temperature as it travels from the keg to the faucet. The beer is pumped from the keg using CO2 or beer gas, just like in a direct draw system.

Air cooled long draw systems, on the other hand, use a forced air blower to send cold air from the cooler through a conduit containing the draft lines to the draft tower. The cooled air helps maintain a consistent temperature-forced air system, ensuring the beer remains cold and delicious even over long distances.

Long draw draft systems require regular maintenance and cleaning to ensure optimal performance and taste. Line cleaning services and preventive maintenance are crucial in preventing build-up and contamination that can adversely affect the quality of the beer being served.

Components of a Long Draw System

The Walk-In Beer Cooler

The walk-in beer cooler is a crucial component of the long-draw draft system. Its primary function is to keep the kegs at the optimal serving temperature, usually between 36-38°F. The whole walk-in cooler must be temperature-controlled to ensure the beer's quality and maintain proper carbonation levels.

The Draft Tower

The draft tower, also known as the beer tower, is the visible part of the draft system where the faucets are mounted. It provides both an aesthetic and functional role. The temperature of the tower must be consistently maintained to prevent foaming and ensure the beer is served at the proper temperature.

Nitrogen Separator

The nitrogen separator ensures a consistent blend of gas is supplied to the beer. Typically, a blended gas like beer gas (a mixture of CO2 and nitrogen) is required for long-draw systems. The nitrogen separator is responsible for separating the gas components and accurately adjusting the gas mix to keep the beer serving at its best quality.

Nitrogen Separator

The Beer Line

Beer lines, also known as trunk lines or draft lines, are specially designed tubes that transport the beer from the cooler to the draft faucet. These lines should be made with durable materials to prevent taints and maintain proper pressure and temperature during transportation. In long draw systems, trunk lines often include glycol-cooled lines to ensure the beer stays cool throughout the whole journey.

Secondary Regulators

Secondary regulators allow for individual pressure adjustment to each tap, ensuring that each beer is poured into push kegs at the correct pressure. They're installed between the primary regulator, which is attached to the air tank (or CO2 and nitrogen tanks), and the keg coupler. Secondary regulators prevent over-carbonation or under-carbonation by adjusting the pressure for each type of beer.

Glycol Chiller

A glycol chiller, sometimes referred to as a glycol power pack or glycol system, is essential to maintaining proper temperature in long draw systems. This specialized equipment circulates a cold glycol solution alongside the beer lines within a trunk line. The glycol chiller helps keep the beer lines at the optimal serving temperature, even over longer distances.

Glycol Chiller

Beer Fob

Last but not least, the beer fob is crucial for reducing waste in long draw systems. It's a device installed between the keg coupler and the beer line, designed to eliminate beer waste by preventing foam when the keg empties. The fob ensures that the beer line remains full until the keg is completely drained, maintaining the quality and freshness of the beer.

Designing a Long Draw Draft System

Designing a long-draw draft system requires careful planning and attention to detail. This type of draft beer system is necessary when the cooler is not located directly next to the bar and tap, and it allows for the beer lines to run over long distances between the keg storage area and the point of dispensing. To create an efficient and effective long draw system, there are several key factors to consider, such as system design, installation, and the selection of appropriate components.

The first step in designing a long draw draft system is to determine the specific needs of the commercial draft beer system. This includes calculating the required length of beer lines and assessing the available space for component installation. It is crucial to maintain proper temperatures throughout the system, ensuring that the quality and taste of the beer are preserved. There are two primary methods for cooling draft beer systems in a long draw draft system: air cooled and glycol. An air cooled draft system uses a forced air blower to send cold air through a conduit containing the draft lines, while a glycol cooled system pumps a mixture of glycol and water through the trunk line to regulate temperature.

Once the cooling method has been chosen, it is crucial to select the appropriate components for the system. This includes CO2 tanks, regulators, keg couplers, beer lines, and draft towers. Additionally, the materials used for the beer lines and connections should be of high quality to ensure durability and prevent leaks.

The installation process for a long draw draft system is a critical aspect of the project. It requires careful planning and coordination between the various components, including the keg storage area, the draft tower, and the cooling system.

The regulator helps maintain a consistent gas pressure while the CO2 tanks hold the gas mixture. Gas pressure and the correct gas ratio are essential for the smooth flow of beer through the long lines, ensuring that the beer reaches the tap without any complications or disruptions.

The Role of Foaming

Foaming is a common concern in long draw draft systems. When beer warms up and CO2 gas escapes, it can result in a foamy mess each time it is poured. Avoiding excessive foaming is crucial to maintaining beer quality, reducing waste, and ensuring customer satisfaction.

Temperature regulation and proper gas pressure control play significant roles in minimizing foaming issues in long draw draft systems. Keeping the beer lines cool and well-insulated helps maintain the ideal serving temperature, which reduces the chances of CO2 gas escaping and causing excessive foaming. Similarly, maintaining the right gas pressure and ratio ensures that the beer flows smoothly through the lines without agitation, minimizing foam production.

Advantages of Long Draw Draft Systems

Remote draft systems offer multiple benefits in terms of efficiency, quality, and customer satisfaction. One of the main advantages of these systems is their ability to maintain the beer's freshness and temperature over an extended distance by using a glycol-cooled remote system. The glycol and water mixture within the insulated lines enables chilled beer to be served even when the kegs are located far from the faucets.

Using a long draw draft system, bar and restaurant owners can optimize space, as they can store kegs in a separate, centralized location away from the serving area. This can improve operational efficiency and save space in the customer-facing area of the establishment.

Additionally, glycol cooled draft systems contribute to a higher level of customer satisfaction by ensuring consistent quality. As the system maintains the beer temperature and freshness, patrons are more likely to enjoy their experience and return for more. This ultimately increases the establishment's profits and enhances its reputation in the market.

From a business owner's perspective, investing in a long draw draft system allows for better inventory management and reduces the frequency of keg replacements. With this type of system, multiple kegs can be stored in one location, and multiple beer lines can be run to different parts of the establishment, making it easier to monitor stock levels and reduce waste.
