Microbrewery building-Glycol cooling system temperature control
For microbrewery building, a well-designed glycol cooling system is important for both wort cooling and fermentation. A complete glycol system include glycol water tank, chiller, pump and transferring piping etc. We normally equipped two smaller chillers than one big chiller during designing the microbrewery, which mainly considering that once one of the chiller gets something wrong and need time to be fixed, the other chiller can still maintain the approximately the existing fermentation thus protect the beer.
Many customers who are talking about the design of their microbrewery are not very sure about the working process of the 2 chillers, here we explain this controlling process below:
Let’s assume a glycol system including 1x2500L GWT, 2x5hp chillers, 1xGWT pump, 1 cellar control panel. So let’s begin:
The 1x2500L GWT has double glycol outlets and double glcyol return ports.
Chiller 1 connect with glycol outlet 1 and glycol return port 1.
Chiller 2 connect with glycol outlet 2 and glycol return port 2.
Chiller 1 has a controller on the control panel (with two kinds of work conditions, auto model switch/manual model switch)
Chiller 2 has a controller on the control panel(with two kinds of work conditions, auto model switch/manual model switch)
PS: Auto model switch: It means that the chiller will be controlled automatically (on/off)
Manual model switch: It means that the chiller will be controlled manually (on/off)
Automatic control
We set for example 15Ffor the GWT on the control panel.
And we switch both the chiller1 and chiller 2 work model to ‘auto’.
When the actual temperature in the GWT is above 15F (measured by the temperature probe).
The controller will commands firstly the glycol pump to recirculate the liquid to the chiller1 and 2, after the liquid reaching the chiller 1 and 2,
the chiller 1 and 2 will work automatically to cool the liquid, the liquid keeps recirculating and finally reach 15F, then all machine stops automatically.
Manual control
We can also just let for example Chiller 1 on switch ‘autom’, and let the chiller 2 on switch ’manual’.
Then in this whole process, the chiller 2 will not be controlled by the control panel.
Only the chiller 1 participate the completing chilling process described above.
Please feel free to contact us if there is more questions from you about building up the microbrewery.
