What are they and how do they work?
A jockey box system can sometimes be called a coil box or cold plate box. The name Jockey stems from the portability of the unit as it is easy to move from one location to another (jockey around).
A Jockey Box system contains all the equipment necessary to dispense beer; cooler box, beer line – stainless steel coils or cold plates, shank, faucet, CO² regulator, CO² tank and beer line connectors, and some come equipped with a drain tray and cup holder. CO ² gas is used to pressurized the keg for dispensing.
The key to the Jockey Box dispensing cold beer is the coil or cold plate unit that acts like a flash chiller meaning that the stainless steel beer line coil or aluminum cold plate (stainless steel line is encapsulated) is refrigerated using an ice water bath in the case of the coil system or ice only with the cold plate.
The Jockey Box system works on the principles that the keg is sitting at room temperature, 70º F and when the beer passes through the coil or cold plate located in the cooler box the beer temperature will drop to the ideal dispensing temperature of 38º F. It is the perfect system for large parties or special events such as a family reunion or company picnic. As it does not require electric it can be set up anywhere. CO ² gas is used to pressurized the keg for dispensing.
Keeping the keg cool is important to the function of the Jockey Box system and that is why it is recommended that keg jackets be used to ensure cold beer. Kegs when used with a Jockey Box system should never be stored in direct sunlight and in the heat of the summer it is wise to place the keg in an ice water bath in a tub. This way, the beer in the keg stays cold and the performance of the Jockey Box remains optimum.
Coil systems – The coil should be fully submerged in the ice water bath and as the ice melts the water should be drained and more ice added. Be sure to keep the drain closed on the cooler box and only open when draining water to add ice.
Cold plate systems – only ice should be used with cold plates, no water, and as the ice melts it should continually drain, remember to leave the cooler box drain open and run a drain line to a bucket to collect the water
Jockey Boxes are not for everyone, because they are not designed for long-term use. they are, however, perfect for 1 to 2 day parties and special occasions. They are completely portable and fun to use.
Just like all draft beer systems, Jockey Box systems require regular cleaning. All beer contact points – faucet body and faucet parts, coils or cold plates, beer line connectors and drain tray should be cleaned after each use.
