  • Which Heat Exchanger Is Best? The Three Main Types ...

    2021-8-31 · The shell and tube heat exchanger in the photo above has about twelve times the efficiency than a hypothetical single-tube heat exchanger of the same size. However, there is a disadvantage to smaller tubes – if the fluid in your application is very viscous or has particulates, it can foul up the tube and undermine the heat transfer process.

  • Twisted Tube™ Heat Exchanger Technology - Koch Heat

    TWISTED TUBE® Heat Exchanger Technology features a revolutionary bundle construction that increases heat transfer and reduces pressure drops while increasing heat transfer surface area and eliminating damaging vibration. Additionally, dead spots are eliminated where fouling can accumulate and reduce effective heat transfer surface area.
