All in topic →Cooling Tower vs Dry Cooler: Which to Choose for Equipment Cooling
At +30 °C a cooling tower gives 26–28 °C water, a dry cooler 36–41 °C. Comparing the two on temperature, water, electricity, climate and…
How Much Water Does a Cooling Tower Use, and How to Cut Make-Up
A 1,000 m³/h cooling tower evaporates up to 12.6 m³/h and takes 16.8 m³/h of make-up. Calculating evaporation, drift and blowdown, and…
How to Choose an Industrial Cooling Tower: Open, Closed or Hybrid
An open cooling tower on a 1,000 m³/h loop takes up to 16.8 m³/h of make-up; a closed one keeps the loop clean. Choosing by temperature…
What Is a Cooling Tower? How It Works, Explained Simply
A cooling tower cools water by evaporation, losing about 1% of the flow as vapor per 7 °C of cooling. How it is built, how it works…
Chillers
All in topic →Chiller Total Cost of Ownership: Purchase vs 15 Years of Running
A chiller is 5–15 % of what you spend on cooling in 15 years; a 1,000 kW unit burns up to RUB 26 million of power a year. How to calculate…
