6.0 ยฐC Range
5.0 ยฐC Approach 54.5% Thermal Effectiveness
โšก 60-Second Express Engineering Callback Average Response: 42 seconds
Governing Formula:
Range = Hot Water In - Cold Water Out; Approach = Cold Water Out - Ambient Wet Bulb; Effectiveness = Range / (Range + Approach) ร— 100
Pune Field Notes & Environmental Standards:

Standard plant cooling tower design approach is 4ยฐC to 6ยฐC above ambient wet-bulb temperature.

Technical Engineering Guide & Field Diagnostic Practices

Cooling towers reject heat absorbed from process chillers into the atmosphere through evaporative cooling. Range indicates the heat load dumped by the condenser; Approach indicates how closely the tower cools water toward the ambient wet-bulb temperature boundary.
