Commercial Refrigeration Oklahoma City repairs bar and beverage refrigeration across Oklahoma City for bars, taprooms, breweries, restaurants, and event venues: back-bar and bottle coolers, keg boxes and walk-in keg rooms, and draft-beer glycol systems. Bar refrigeration is judged by the pour as much as the thermometer, so a warm back-bar or a foaming tap gets diagnosed for the whole path, equipment, temperature, and, on draft systems, the glycol bath and trunk line.
What we do on the first visit
The technician checks the cooler or keg box across condenser, evaporator, fans, defrost, and door, and on a draft system checks the glycol chiller bath temperature, pump and circulation, trunk-line insulation, and the temperature at the faucet. Back-bar fans, controls, gaskets, and keg-box defrost issues are usually same-visit; glycol pumps, chiller repairs, and trunk-line problems are quoted in writing.
Foam is usually temperature and pressure, not the keg
Persistent foam at the tap almost always comes back to beer that warmed somewhere between the keg and the faucet, or a CO2 pressure that does not match the beer's carbonation and the line run. On a glycol system that means the bath is running warm, the pump is weak, or the trunk line has lost insulation or contact with the glycol bundle. Commercial Refrigeration Oklahoma City checks the bath temperature, the circulation, and the faucet temperature, and gets the cold all the way to the pour.
Keg boxes and first-pour temperature
A keg box or walk-in keg room needs to hold 36–38 °F steadily, including right at the coupler where the first pour comes from. A frosted coil, a weak evaporator fan, a defrost fault, or a leaking door lets the top of the box or the area near the door drift warm, and the first few pours of a shift foam. The fix is the same disciplined cooler diagnosis, with attention to airflow around the kegs and the door seal.
Insurance and payment
Beverage-cooler failures rarely rise to a spoilage claim, but for a brewery or high-volume bar Commercial Refrigeration Oklahoma City provides itemized invoices and a service record. Draft-system tuning is documented so staff know the target bath and pour temperatures.
What's included
- Back-bar and bottle cooler diagnosis: condenser, evaporator, fans, defrost, door
- Keg box and keg-room diagnosis with attention to first-pour temperature
- Glycol chiller service: bath temperature, refrigeration circuit, controls
- Glycol pump and circulation testing and replacement
- Trunk-line and faucet temperature check on draft systems
- Gasket, sweep, hinge, and anti-sweat heater replacement
- Refrigerant leak check and charge correction by weight
- Target bath and pour temperatures documented for staff
Symptoms we get called for
- Back-bar cooler warm and beer or mixers not cold enough to serve
- Keg box not holding 36–38 °F, first pours foamy
- Draft lines pouring foam all night, then flat
- Glycol chiller icing, cycling, or the bath running warm
- Bottle cooler sweating, iced coil, or failed lighting
- Compressor noise from the back-bar line during service
