Pub & Bar Refrigeration Brisbane

A Brisbane keg cellar has to run at 2–4°C while sitting inside a building where the ambient regularly hits 34°C in summer. That's a 30°C temperature difference across the cool room wall, on top of every keg swap opening the door for a minute at a time. Add a Python beer trunk running 20m from cellar to bar, and you have four separate places the pour can warm up before it hits the glass.

The systems we spec are sized for Brisbane class 4/5 ambient — condensing units with 20–30% more capacity than the European sheet suggests, insulated Python of the right diameter for the run, and glycol chillers with proper heat rejection paths out of the building.

The single biggest design decision for a Brisbane pub is direct-draw versus glycol dispense:

• Direct-draw — keg-to-tap run under 3m, insulated. Cheapest to install. Only viable when the bar sits directly above or beside the cellar.
• Glycol — chilled propylene glycol circulated alongside the beer lines inside an insulated Python. Handles runs to 60m, keeps beer at 2°C from cellar to font. Essential for any bar that's more than 3m from the cellar or has multiple bars off a single cellar.

We size the glycol chiller for peak Brisbane summer load, plus 20% headroom, and locate the heat-rejection condenser outside the building — never in the cellar itself. Bad glycol design is the number-one reason Brisbane pubs pour foam on a busy night.
