Neoprene beer keg cover for cooling

Insulated neoprene jacket for beer keg to chill and preserve

The neoprene keg cooling jacket 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 dispense line. Ideal for tap dispensing, it ensures a refreshing, delicious experience every time. A smart investment for enthusiasts and professionals alike.

Neoprene jacket 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 as a perishable food. Craft beer is a living product affected by a number of factors, such as:

- Light (more specifically UV radiation)

- The Temperature

- Oxygen

The chilled neoprene keg cover is a practical, portable solution for cooling and preserving your favorite beers. Made from high-quality insulating neoprene, this cover keeps beer at its optimal temperature, ensuring freshness and flavor at all times. Its flexible, adjustable design fits various keg sizes and allows for easy installation and removal. Ideal for outdoor events, parties, or gatherings, the chilled neoprene cover gives you 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‑butene‑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 5 mm 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, we will need to keep it 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 define the ideal temperature as 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 down. Above this temperature, fatty acids combine with oxygen (a small amount always enters when tapping the keg), producing substances that give the characteristic flavor of paper, cardboard, or damp wood, which will ruin your beer.

On the other hand, for beers to which we add CO2, temperature will be critical, with its worst enemy being fluctuations. By keeping the temperature stable with the sleeve, we achieve proper counterpressure, preventing the beer from becoming over- or under-carbonated, resulting in beer with ideal carbonation.

The Neoprene sleeve helps keep the temperature stable and within the proper range to serve quality beer.

5 mm thick high-density neoprene sleeve.

With heavy‑duty professional zipper of high strength and quality.

It has 9 turns of cooling coil around the keg (6 metres of tubing).

Connections to the cooled line with 8 mm stainless steel barb.

No power consumption for the cooler when using an outlet from the agitator motor pump.

Relative air humidity up to 80% (above this level there is a risk of condensation).

There is no condensation on the cover or water around the keg with a relative air humidity below 80%.

By keeping the product temperature 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 is between 10ºC and 15ºC to maintain its quality (12ºC is optimal). From 17ºC upwards, an unpasteurized beer begins its secondary fermentation, and below 9ºC there is a risk of over-carbonation in less than 24 hours.

Product patented both as a utility model and as an industrial design.

LAB TEST:

With an ambient temperature of 30º, a keg with a product temperature of 32º is placed inside the jacket, which is connected to an outlet of the agitator motor pump. Water at zero degrees is circulated through the jacket, returning to the tank 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 14ºC and the return water to the bath is 0.2ºC.

After 36 hours of operation, based on the results obtained under the specified ambient temperature and relative humidity conditions, we find that the internal temperature of the keg has stabilized at around 12ºC. The return water is at 0.1ºC.
