At every single one of these

retailers you will find a

Dispensing System with one

vital piece of Equipment…

The CO2 Gas Cylinder

Since 1902, the CO2 gas cylinder has remained virtually the same…

“…Harrisburg Steel Corporation (Harrisburg Pipe)

installed two new furnaces and used the plate process to produce America’s first seamless gas cylinders in 1902…”

* Published June 14. 2005, “A Brief History of Gas Cylinders”, Compressed Gas Manufacturers Association

In 1904, the gas cylinder really took off…

…”Two years later, a prominently placed carbon dioxide cylinder would further advance the cylinder business, when the Anheuser-Busch Brewery displayed a carbon dioxide cylinder from Harrisburg Steel Corporation to pump draft beer at the 1904 World’s Fair in St. Louis. Beer on tap became so popular that many saloons were renamed taprooms—giving carbon dioxide cylinders a starring role in watering holes across the nation.” *

Carbon Dioxide gas

is a by product of

many petrochemical

industries

Where it is captured,

cleaned and liquefied

Liquefied CO2 is

transported to

Industrial Gas

Suppliers

Bottles are

professionally filled

at site centric plants

Transporting CO2

cylinders need to

comply with USDOT

Regulations

Draught Beer has Cooling needs and issues

that Soft Drink dispensing does not

have…

In the Draught Beer

industry, a constant

challenge centers on

temperature issues and the

time, energy and effort

needed to serve a Draught

Beer at 38*F (optimal)

“Our mission is to

create innovative

solutions to enhance

the Draught Beer

Experience for the beer

lover – brewer,

distributor and retailer

by ensuring optimal

preservation and

dispensing of the

finest form of Beer –

Draught Beer.”

The higher the beer temperature - the higher the CO2 pressure needed to dispense.

The higher the CO2 pressure - the higher the foaming.

The higher the foaming - the higher amount of wasted beer.

Carbonation Scale

World Cup 2006

It was estimated that nearly 40% of all Draught Beer could not be dispensed at Stadium Concession Stands and Outdoor Venues due to the hot weather in Germany at the month long FIFA World Cup tournament

What should have been this…

May have led to this…(kidding)

How Dry Ice can change the way Carbonated Beverages are Cooled,

Carbonated and Dispensed…

Dry Ice is Solid Carbon

Dioxide

It Sublimates (changes)

into CO2 Gas

Extremely Cold (-109*F)

How is Dry Ice

made?

Dry Ice is almost 5x

colder than Wet Ice

Where Can I Get Dry

Ice?

› Over 4,500* Retail

Locations including

Grocery Stores, Big

Box Retailers and

Specialty Stores

* According to Airgas, the largest Dry Ice

seller in the US

How Much does Dry

Ice Cost?

› Around $1.00 –

$1.50 per pound

(retail)

More Energy Efficient

Dry Ice can lessen the heavy load needed to Cool carbonated

beverages dispensed from kegs

More Cost Efficient

Dry Ice can lower the amount of Draught Beer foaming (waste)

Dry Ice can lessen the time and energy needed to Cool

More Availability

Dry Ice can open up new areas of service for Draught Beer

More Enviro - Friendly

Dry Ice could lessen the heavy Carbon Footprint for Beer

More Energy Efficient

Dry Ice can lessen the heavy load needed to Cool carbonated beverages dispensed from

kegs *

* By lowering the amount of electric energy required for artificial refrigeration directly

to Cool or to create Wet Ice for contact cooling.

More Cost Efficient

Dry Ice can lower the amount of draught

beer foaming (waste) *

* By improving Cooling efficiencies, Dry Ice

can lessen the amount of CO2 pressure

needed as well as lowering energy bills

More Availability

Dry Ice can open up new areas of service

for Draught Beer *

* Draught Beer service is currently limited

by a number of factors aligned with

Cooling and CO2 pressure issues

More Enviro – Friendly

Dry Ice systems could lessen the heavy

Carbon Footprint for Beer

* By lowering the time and electric energy

currently required for optimal cooling

Option 1: Cooling the

Keg

1. Artificial Refrigeration:

Kegerators or Walk-In

Refrigerators

2. Ice Bath

Option 2: Cooling the

Beer lines

1. Jockey Box System

2. Flash Chiller

Artificial Refrigeration

1. Keg Refrigerators or Kegerators can be found in retail locations as well as individual homes (Man Caves)

2. Walk In Refrigerators

Wet Ice

1. Kegs are placed in

wet ice baths

2. Ice bags are placed

on top of Keg

Jockey Box System

1. Insulated container filled with wet ice & water

2. Keg and CO2 tank standing at room temperature

3. Beer is run through lines that are submerged in ice bath

Flash Chillers – Ice Bank

1. Keg and CO2 tank at ambient temperature

2. Beer is pushed through beer lines located in an ice bath

3. Flash Chiller/Ice Bank Unit is similar to an ice making machine as it creates an ice bath inside the machine

In 2006, while creating a new Kegerator, we first researched using Dry Ice to quickly Cool the Keg

It is estimated that it takes 12-24 hours to cool a keg from 48*F to 38*F in a Kegerator – Walk In Refer

We also tried to create a Kegerator where the CO2 cylinder wouldn’t sit outside

Cooling Ring Solutions – Dry Ice using Pressure Vessels that are placed on top of Kegs for Contact Cooling

Cooling Canisters Solutions – Dry Ice using Pressure Vessels that are placed inside Jockey Box and some Flash Chiller Systems

Cooling Bags & Boxes Solutions – Dry Ice using Pressure Vessels that are placed inside some Jockey Box and some Flash Chiller Systems

We created the first of many different Pressure Vessels using Dry Ice

Toroidal Shaped High Pressure Vessel that when placed on top of a Keg, creates intense contact cooling

Captures sublimating CO2 gas

The Cooling Ring

We have created several Pressure Vessels that can be used in Jockey Box and Flash Chiller Systems

These are placed inside the Ice Baths to preserve the Cooling and greatly lessen the amount of wet ice needed

Eliminates the standard CO2 cylinder

The Cooling Canister

The Cooling Bags & Boxes

These Pressure Vessels are used specifically for use in Ice Bank Units and Jockey Box systems

They fit in “tight” spaces

The Cooling Box allows for easy insertion of up to 11 lb block of Dry Ice

Dry Ice Solutions

“Keg-U-Later has created solutions to

capture the Cooling and Sublimation

powers of Dry Ice for an alternative way

to Cool, Carbonate and Dispense

carbonated beverages…”
