Beer In Regulator: The Ultimate CO2 Guide For Newbies

The Primary Beer CO2 Regulator

The primary beer CO2 regulator is responsible for delivering the main source of CO2 to a draft beer system. This includes delivering CO2 to other secondary beer regulators downstream, to gas blenders, or directly to a keg in a kegerator gas tank. Proper gas pressure is essential for delivering CO2 effectively to maintain the quality of the beer.

Gas regulators play a crucial role in managing this gas pressure, ensuring that the system operates efficiently and safely.

Understanding this piece of cold draft equipment is crucial to brewing, and dispensing regardless of the type of beer system - be it a remote draft beer system, direct-draw, or a simple kegerator. Proper dispensing pressure is vital for achieving a well-carbonated beer head and maintaining the overall quality of the beer.

In this Ultimate guide, I aim to cover everything you need to know. Let’s dive in!

How To Use a CO2 Regulator?

1. When you acquire your primary regulator, you will also need a CO2 tank to connect it to. Additionally, a crescent wrench is required to tighten the nut on the regulator.
2. The CO2 cylinder will have a male end. Before attaching the primary regulator, ensure it has a seal. While some regulators come with pre-seals, others might require a separate tank washer. If in doubt, ask your beverage CO2 supplier, or your distributor.

1. Once you have a seal, screw the primary nut clockwise until it’s tight, and then use the crescent wrench to further tighten it.
2. Make sure the Primary Co2 Regulator is shut off and set the pressure accordingly.

Primary vs. Secondary CO2 Regulators: How They Work Together in a Draft Beer System

Understanding the distinction between primary and secondary CO2 regulators is essential for anyone looking to master their draft beer system. The primary regulator is the initial control point for gas pressure coming from the CO2 tank. It reduces the high pressure from the tank to a lower, more manageable level that can be used by the system. This regulator is equipped with a pressure relief valve to ensure safety and prevent over-pressurization.

In contrast, secondary CO2 regulators are used to further adjust the dispensing pressure for individual kegs. This is particularly useful when dealing with multiple kegs that require different pressures to achieve optimal carbonation levels for various beers. By using secondary regulators, you can fine-tune the pressure for each keg, ensuring that each beer is dispensed perfectly.

Together, primary and secondary regulators create a seamless system that allows for precise control over gas pressure. This ensures that each beer maintains its intended flavor and carbonation, providing a superior draft beer experience. Whether you're using a simple kegerator or a complex draft beer system, the collaboration between these two types of regulators is critical for achieving the best results.

How To Read a CO2 Regulator Gauge?

1. After connecting the regulator to the CO2 cylinder, ensure that the primary lever is parallel to the floor, indicating it’s in the shut-off position. It should be closed initially.
2. With the valve closed, open the CO2 cylinder to let the gas flow to the regulator. For those using a double gauge, the bottom left gauge should point to green, which indicates the cylinder’s capacity.
3. The gauge displays the cylinder’s fullness level - from green (full) to red (empty), indicating when it’s time for a replacement.
4. The top gauge on the primary regulator displays the pressure being sent to your beer system. Typically, gauges range from 0-160 psi, and it’s rare to need pressure above 100 psi.

Where Should The Primary Regulator Be Set At?

This largely depends on the  draft beer system:

• For a kegerator with a single beer brand, the primary regulator shouldn’t exceed 12 psi.
• For a direct draw system with 50 taps, setting it to 100 psi and adjusting the pressure with secondary regulators downstream is more appropriate. Applied pressure on the kegs of beer should be around 12-14 psi.

How To Adjust The CO2 Regulator?

1. Depending on the regulator type, the adjusting handle, screw, or knob is prominently placed on the regulator front.
2. For Taprite, there’s a plastic knob that you pull towards you to adjust, then turn clockwise to the desired pressure.
3. Other primary regulators might use a screw that’s turned with a straight-edge screwdriver. Clockwise increases the pressure, and counter-clockwise decreases it.

Recommended Primary Beer Regulator

Best Overall:

Taprite Primary Regulator: Known for its user-friendly design, this regulator features a convenient red knob on the front for easy pressure adjustments. Once the desired pressure is set, simply push the control knob in to lock it.

1. ToF Primary Regulator: Another excellent choice, the ToF Primary Regulator is praised for its precision and durability, making it suitable for both home and commercial beer systems.

Summary

We covered the essential steps to securely attach the primary regulator to a CO2 cylinder using a crescent wrench, ensuring a proper washer or seal is in place. We also discussed how to read the gauges on the secondary regulator and make necessary adjustments.

My top recommendation is the Taprite Dual Gauge Primary CO2 Regulator, an ideal first gas regulator for both kegerators and commercial beer systems. The ToF Primary Regulator is also a strong contender for those seeking precision and durability.
