The Krups BeerTender B95 is a popular home draft beer dispenser designed to deliver perfectly chilled beer straight from the tap. Many enthusiasts wonder if the B95 can maintain optimal serving temperatures without adding ice. This technical guide explores whether the unit effectively chills beer on its own, how it compares to similar models, and what adjustments can improve its performance. The insights provided here will help you optimize the BeerTender B95 for reliable, ice-free operation.
How the Krups BeerTender B95 Cooling System Works
The BeerTender B95 uses a thermoelectric cooling system rather than a compressor or external ice to reduce and maintain beer temperature. This technology draws heat away from the keg chamber through a Peltier element, which transfers heat to the rear of the unit. An integrated fan dissipates the heat while circulating cooler air inside the chamber.
This approach provides consistent cooling but has limitations when compared to compressor-based dispensers. The B95 is engineered to reach temperatures as low as 37.4°F (3°C), although actual performance may vary depending on ambient room temperature.
Temperature Test Results Without Ice
To evaluate if the BeerTender B95 can chill beer without ice, a controlled test was performed using a standard 5-liter Heineken DraughtKeg at an ambient temperature of 72°F (22°C). The keg was pre-stored at room temperature to replicate real-world conditions. The test measured the time required to reach target serving temperature.
Test Parameters:
- Keg Type: 5L Heineken DraughtKeg
- Initial Keg Temperature: 72°F (22°C)
- Ambient Room Temperature: 72°F (22°C)
- Cooling Duration Measured: 24 hours
Key Findings:
- After 4 hours, the beer reached approximately 55°F (13°C).
- After 8 hours, the temperature dropped to 46°F (8°C).
- After 12 hours, the beer measured 40°F (4.4°C).
- By 16 hours, it stabilized at 38°F (3.3°C).
- No further significant cooling occurred beyond 16 hours.
These results confirm the BeerTender B95 can chill beer to near-optimal serving temperatures without the use of ice, provided adequate time is allowed. However, pre-chilling the keg in a refrigerator significantly reduces this time.
Optimizing Cooling Performance Without Ice
Although the B95 can chill beer unaided, several techniques improve its efficiency:
Pre-Chilling the Keg: Always refrigerate kegs for at least 12 hours before installation. Starting with a cold keg shortens cooling time to under 2 hours.
Ensuring Airflow: Keep the unit’s rear vent clear. Obstructed airflow prevents heat dissipation, slowing the cooling cycle.
Ambient Temperature Control: Operate the B95 in a cool room. High ambient temperatures over 77°F (25°C) reduce cooling efficiency and extend chill time.
Sealing the Lid Properly: Ensure the lid is fully closed and latched to maintain an insulated environment.
Installation Guidelines for Efficient Cooling
Proper installation affects the BeerTender’s ability to chill without ice.
Place the unit on a level, stable surface with at least 4 inches (10 cm) of clearance behind and on each side for airflow. Avoid direct sunlight or heat sources. Plug the unit into a dedicated power outlet. Insert the keg following manufacturer instructions, ensuring the tap tube is securely attached and the lid is fully closed. Power on the unit and wait for the cooling indicator to signal readiness.
Tools Required
- Phillips screwdriver (only if accessing internal components)
- Soft cloth for cleaning vents
- Digital thermometer (to confirm keg temperature)
Troubleshooting Common Cooling Issues
If the BeerTender B95 fails to reach target temperatures, several causes may be involved:
Obstructed Ventilation: Dust accumulation on vents restricts airflow. Clean vents regularly to maintain performance.
Faulty Fan: The internal fan may fail over time. If the rear of the unit remains cold while the interior stays warm, the fan likely requires replacement.
Improper Lid Seal: An unsealed lid allows ambient air to enter, preventing cooling.
Excessive Room Heat: Ambient temperatures above 77°F (25°C) will significantly impair cooling efficiency.
Regularly inspect these areas to ensure consistent operation.
Customization and Optimization Tips
Advanced users can enhance performance further:
External Cooling Support: Placing the BeerTender in a refrigerated environment or near an air conditioner helps the thermoelectric element maintain lower temperatures.
Thermal Insulation Enhancements: Adding a thin layer of food-safe insulation around the keg chamber (without obstructing airflow) improves heat retention.
Upgraded Fans: Replacing the factory fan with a higher airflow model improves heat dissipation, though this requires moderate technical skill.
Comparison with Similar Products
Compared to compressor-based kegerators such as the EdgeStar KC2000, the Krups BeerTender B95 is quieter and more energy-efficient. However, the B95 requires significantly more time to cool a room-temperature keg. Compressor units can chill beer within 4-6 hours regardless of ambient temperature.
Thermoelectric systems like the B95 are ideal for users prioritizing compact design and minimal noise but less suited to rapid chilling needs.
Compatibility with Other Beer Systems
The BeerTender B95 is designed exclusively for 5L DraughtKegs and does not accommodate traditional ball-lock or Sankey kegs. Kegs must feature an internal CO2 system, as the B95 does not supply external gas.
Attempting to use unapproved kegs or adapters may compromise cooling performance and void the warranty.
Frequently Asked Questions
Can I use ice to speed up cooling in the BeerTender B95?
No, the B95 is not designed to accommodate ice. Adding ice or water to the chamber can damage internal components.
How long does it take to chill a pre-refrigerated keg?
If the keg is already at 40°F (4°C), the B95 will maintain serving temperature within 1–2 hours.
Does ambient temperature affect cooling performance?
Yes, higher ambient temperatures can extend chilling time or prevent the unit from reaching optimal temperatures.
What is the lowest achievable temperature without ice?
The unit typically maintains beer between 37–39°F (3–4°C) under ideal conditions.
Is it safe to operate the B95 continuously?
Yes, the BeerTender is designed for continuous operation to maintain consistent temperatures.
Can I use third-party kegs with the B95?
Only kegs compatible with the BeerTender system are supported. Other kegs may not fit or cool correctly.
Conclusion
The Krups BeerTender B95 can successfully chill beer without ice, though users must allow sufficient time for the thermoelectric cooling process. Pre-chilling kegs, maintaining proper ventilation, and operating in cool environments significantly improve performance. While not the fastest chilling system available, the B95 offers a quiet, energy-efficient solution for enjoying perfectly cooled draught beer at home.
