This guide explains what the cooling calculator computes, how each input changes the result, and how to turn the output into a comparable request for quotation. Worked examples below are produced with the same engine that powers the live tool.
Replace the default values in the cooling calculator with your own flock size, targets and local costs. Defaults are commercial-sector averages, not a recommendation.
2
Compare the three scenarios
Switch between conservative, expected and optimistic to see how sensitive the result is to your assumptions before committing capital.
3
Read the assumptions
Check the assumptions panel so you know what the model excludes — typically taxes, import duties, special civil works and land.
4
Turn the output into a quote request
Send the resulting figures in a single request to receive comparable offers from qualified third-party manufacturers.
Every input explained
Default values are commercial-sector averages. Replace them with your own figures — your data always overrides the defaults.

Planning assumptions
The cooling calculator uses common commercial-sector parameters; your own measured data always overrides the defaults.
The conservative scenario adds a safety margin; the optimistic scenario assumes favourable operating conditions.
Taxes, import duties, special civil works and land cost are excluded unless stated otherwise.
It is a class-4 planning estimate (roughly ±30%). Use it to compare options, size an investment and prepare a quotation request — it does not replace engineering design or a bankable feasibility study.
Yes, that is the intended use. Turn the results into a requirement list and send a single request to receive comparable offers from qualified third-party manufacturers. Any firm quote overrides the estimate.
Yes. Climate, grid voltage and stability, labour cost, import duties and logistics all move both the sizing and the cost. State the country in your request so the adjustment is priced into the offer.
Use the guide to understand the inputs and see worked examples, then run the calculator with your own figures. Both pages are free and require no registration.
Convert it into a requirement list and send one request for quotation. You receive comparable offers from qualified third-party manufacturers, and each firm quote replaces the estimate.
