Frequently asked questions
When should I switch to a central system?
Once the total cooling demand exceeds about 58 kW (50,000 kcal/h), a single central system usually beats separate chillers per machine in both investment and operating cost.
What does a redundant (2+2) design provide?
There are two independent refrigeration circuits with two compressors each. If one circuit is taken down for maintenance or fails, the other continues automatically and production does not stop.
What is calculated for a central system?
The machines' diversity factor, hydronic balance, pipe sizes and buffer tank volume are calculated together. Correct sizing also ensures efficient operation at part load.
