Cold beer, a workable bar and less foam

Cool the keg itself or chill beer on its way to the faucet. Your peak service rate and the heat matter.

Updated October 11, 2026

At a glance

Two ways to cool

Kegerators, keezers and cold rooms refrigerate the keg. Jockey boxes and flash chillers cool beer in a heat exchanger before the faucet. Incoming temperature and continuous flow determine whether a chiller can keep up.

Two cooling locations; storage matters in both.

A keezer is an adapted chest freezer with temperature control. Plan for condensation and keg access; do not drill into walls without knowing the refrigerant route. A kegerator package may exclude the coupler, regulator or filled CO₂ cylinder.

Hot weather and maintenance

Micro Matic recommends protecting the keg from sun and keeping it cool; summer operation may require an ice bath. Coil jockey boxes use ice and water; cold plates generally use ice with meltwater draining away. Follow the model instructions.

For a typical direct-draw system, Micro Matic recommends 38 °F, about 3.3 °C, and line cleaning every two weeks. Pressure depends on carbonation, temperature, altitude and line resistance. Raising pressure alone does not fix foam.

Test consecutive pours at your hottest operating conditions. Measure glass temperature and foam, and assign cleaning responsibility. For a permanent bar, include daily checks and cleaning in every option.

Frequently asked questions

Does a jockey-box coil contain refrigerant?

Beer flows inside the coil; an ice-water bath cools it. An electric chiller has a separate refrigeration circuit.

Can the keg stay warm?

Do not assume so. Follow brewery storage guidance and the chiller capacity limits; in hot weather the keg may need cooling too.
