This online cooling tower calculator helps system designers calculate all necessary parameters at a shot.

With this online calculator, the following information can be calculated.

- Heat Rejection of cooling tower in kw or tonnage.
- Range ( Temperature difference between Inlet water – Outlet water), also referred as EWT- LWT.
- Approach (Temperature difference between Outlet water – Wet Bulb Temperature), also referred as LWT- WBT.
- Evaporation Loss in %.
- Evaporation Loss in m3/hr
- Effectiveness of cooling tower in %

Heat rejection in tonnage.

For general practice cooling tower’s heat rejection is always higher than that of chillers. usually 10-15%, depending on site safety margin.

Cooling tower calculations are the same for all types of cooling towers, Be it a natural draft cooling tower or mechanical draft.
