Beer Cooler and Glycol Chiller Repair for a San Marcos Brewery

June 12, 2026 — San Marcos, TX

Foamy pours and warm taps are more than a customer-service headache for a brewery — they point straight at the refrigeration and glycol system keeping every line cold. Setpoint Services was recently called to a San Marcos brewery where staff were fighting excessive foaming and beverage temperatures that had crept above target at the dispensing stations.

The Symptoms: Foam, Warm Beer, and Lost Product

When draft beer dispenses warm, CO2 breaks out of solution and you get foam — wasted product, slow pours, and frustrated guests. The operator reported both problems together, which usually means the cold side isn’t holding the temperatures the system was set for. Our technicians treated it as a full refrigeration diagnostic rather than a quick adjustment.

What We Checked

• Walk-in cooler performance and temperature stability
• Glycol chiller operation and bath temperatures
• Refrigeration system pressures across the cold side
• Thermostat calibration and sensor positioning
• Beverage temperatures at the dispensing stations

Testing pointed to inaccurate thermostat sensing. The control was reading the space incorrectly and allowing product temperatures to drift above the desired serving range — enough to trigger the foaming and the warm pours the staff were seeing.

The Fix

We corrected the thermostat positioning so it sensed the space accurately, then adjusted the glycol chiller settings to bring the beverage circuit back down to proper temperature. With the walk-in cooler and glycol system working together the way they were designed to, beverage temperatures dropped significantly and clean, consistent dispensing was restored.
