Glycol Chilling Equipment
Heat Transfer – Glycol Reticulation System
The Glycol heat exchange plate reticulation systems is the most commonly installation beer chilling system style in Australia. This consists of a refrigerated glycol tank which maintains the temperature between -1 & –3 degrees. Glycol hilling systems include remote propylene glycol chiller that is situated in the cellar cool room, the best location for efficiency of operations. The Propylene glycol & distilled water mixture is known as heat transfer fluid at a 30% glycol / water mixture for optimal pump efficiency.
NOTE: Self contained glycol chilling systems should be installed outside the cool room to eliminate any heat rejection from the cool room.
The heat transfer fluid circulated through glycol manifolds to the beer python and ultimately through beer fonts to give either a sweating or frozen appearance. For better efficiency for pumps install Bracton’s stainless steel insulated 25mm internal glycol manifolds for greater flow rates.
Glycol / Beer Lines Under 30 metres
- Beer size 6.35mm ID
- Triple Nylon tubing
Glycol / Beer Lines Over 30 metres
- Beer size 8mm ID
- Triple Nylon tubing
- 25mm Insulation All states excluding Queensland and northern New South Wales
- 32mm Insulation Queensland and All states where python is installed in high humidity areas.
The Glycol and beer is than connected to a cast alloy ingot stainless beer lines and glycol circuits such as Bractons Sub Zero chiller plate this allows any heat to be transferred into the plate. All chiller plates glycol flow should have a minimum flow rate of eight litres a minute. The Plate is to be installed in a well-ventilated area to restrict any surface sweating. Glycol is then directed to the fonts to be flooded. All beer and glycol tubing is to be insulated so that no heat is generated into the beer. There should be no evidence of condensation underneath the bar.
Please note: avoid installing U-bends and elbows due to restriction of liquid flow.
