Cooling Tower TWI Series

TWI Series Industrial Cooling Towers are specially designed for heavy duty industrial and process applications. It provides more wetted surface for uniform water distribution and high heat transfer rate. The structure of TWI Series Cooling Tower is a very durable tropical hardwood or FRP Pultruded tower body and heavy duty fan machinery to ensure NO equipment downtime and production delays. Fan machinery and heat exchange media are optimised to deliver maximum horsepower for lower operation cost.
