Energy Savings
Hi Friends!
To our brewery, where we have three J&E Hall monoscrew chillers, we have added a new chiller recently. The previous ones were all water cooled, with cooling towers. The new chiller installed has an evaporative condenser and is fitted with VFD. The system works to provide chilled glycolated water at -6 deg.C. Propylene glycol is used.
We have an automatic control whereby the last chiller does the modulation while the other three work on full capacity only. This is all as per recommendations of J&E Hall.
Since the installation has been made we are consuming much less electricity now and we are quite happy with the new installation.
But still I would like to know whether there are further steps to be taken for more energy savings. I am actually looking into moving from -6 deg to -4 deg.C.
Are there any other areas where savings can be made?
I have a 5-yr old chiller, water cooled with a cooling tower which can be converted to take an evaporative condenser. Do you think it's worthwhile?
I'll be pleased to have your views.
