Chiller & Cooling Tower Calculator
Estimate the chiller capacity, matching cooling tower, water flow rates and power for your building's cooling load — the central-plant numbers HVAC engineers need first. Adjust the inputs, then get an engineered design.
Your cooling load
Uses standard ratios — chilled water 2.4 GPM/TR, condenser water 3 GPM/TR, cooling tower ~1.25× chiller TR. Plant selection also considers part-load (IPLV), redundancy and pumping.

Thanks! Our HVAC team will send your tailored chiller plant design within one business day.
Indicative estimates only — not a binding design. Actual plant sizing depends on the detailed heat load, diversity, IPLV efficiency and redundancy strategy.
