Chilled neoprene jacket for beer keg to cool and preserve
The neoprene cooling jacket for kegs is your ally for keeping beer and beverages at the perfect temperature. It uses the same cold‑water recirculation from the ice‑bank cooler to keep the keg at the same temperature as the dispensing line. Ideal for tap dispensing, it ensures a refreshing, delicious experience every time. A smart investment for enthusiasts and professionals.
Neoprene sleeve for cooling beer kegs and keeping product temperature stable at all times.
Keg cover models for 20 and 30 liter KeyKeg and conventional 20 and 30 liter stainless steel kegs.
Because craft beers are not pasteurized, they must be treated like a perishable food. Craft beer is a living product affected by a number of factors, such as:
- Light (specifically UV radiation)
- The Temperature
- Oxygen
The chilled neoprene beer keg sleeve is a practical, portable solution for cooling and preserving your favorite beers. Made from high-quality insulating neoprene, this sleeve maintains the beer’s optimal temperature, ensuring freshness and flavor at all times. Its flexible, adjustable design fits various keg sizes and allows easy installation and removal. Ideal for outdoor events, parties, or gatherings, the chilled neoprene sleeve offers the convenience of having cold beer always at hand, without the need for additional refrigeration equipment.
LIGHT
In English, a beer spoiled by light is said to be “skunked” and, chemically speaking for those interested, the compound 3-methyl-2-buten-1-thiol is formed by an isomerization reaction. This compound is one of those found in the liquid sprayed by skunks and is responsible for the distinctive unpleasant smell and taste.
Craft beers should be stored in dark places away from bright fluorescent lights and especially from sunlight. Thanks to the 5mm neoprene sleeve, practically 100% of UV radiation is absorbed, so the beer will not be affected by this undesirable effect.
TEMPERATURE
As a general rule, for every 10ºC increase in temperature, the beer’s shelf life is cut in half. Depending on the type of beer, it must be kept at different temperatures. For example, in hoppy beers (IPAs, APAs, etc.), the effect of heat is much more noticeable and they can deteriorate quickly at temperatures above 20ºC.
As a general rule, we can consider the ideal temperature to be between 10ºC and 15ºC depending on the type of beer, with 12ºC being optimal, since at this temperature most of the reactions that degrade beer are deactivated or greatly slowed. Above this temperature, fatty acids combine with oxygen (a small amount always enters when tapping the keg), producing substances that give the characteristic paper, cardboard or damp wood flavour that will ruin your beer.
On the other hand, for beers to which we add CO2, temperature will be critical, with fluctuations being its worst enemy. By keeping the temperature stable with the sleeve, we achieve proper counterpressure, preventing the beer from becoming over- or under-carbonated, and as a result obtaining beer with ideal carbonation.
The Neoprene sleeve will help us keep the temperature stable and within the right range to serve quality beer.
5mm thick high-density neoprene sleeve.
With professional, high‑strength, high‑quality zipper.
It has 9 turns of cooling tube around the keg (6 meters of tubing).
Connections to the chilled line with 8mm stainless‑steel barbed fitting.
No power consumption for the cooler when using an outlet from the agitator motor pump.
Relative air humidity up to 80% (above this there is a risk of condensation).
There is no condensation on the cover or water around the keg at a relative air humidity below 80%.
By keeping the temperature of the product inside the keg stable, we can regulate the CO2 pressure, thus avoiding both over-carbonation and de-carbonation of the product.
The ideal temperature for beer should be between 10º and 15º to maintain its quality (12º is ideal), and from 17º onwards an unpasteurised beer begins its second fermentation, while below 9º there is a risk of over-carbonation in less than 24 hours.
Product patented both as a utility model and as an industrial design.
Utility model patent number: P201700662
Industrial design registration number: 0526522
LAB TEST:
With an ambient temperature of 30º, the keg, with a product temperature of 32º, is placed inside the jacket, which is connected to an outlet from the agitator motor pump. Water at zero degrees is circulated through the jacket, returning to the bath at a temperature of 0.5º.
After 16 hours of operation under the same external conditions, we find that the temperature inside the keg is 17ºC and the return water to the bath is 0.3ºC.
After 24 hours the temperature inside the keg is 14º and the return water to the bath is 0.2º.
After 36 hours of operation, based on the results obtained under the specified ambient temperature and relative humidity conditions, we find that we have stabilized the internal barrel temperature at around 12ºC. The return water is at 0.1ºC.
