Baffle-Free
Tube
Support
Brown Fintube's innovative Twisted
Tube Design avoids the need for baffles. The unique helix
shaped tubes are arranged in a triangular pattern. Each tube
is firmly and frequently supported by adjacent tubes, as shown in
the illustration on the left, yet fluid swirls freely along its
length. This support system eliminates tube vibration, which
is a common problem in some heat exchanger
services.
The twist
arrangement for baffle-free support with gaps aligned between the
tubes also provides for easier cleaning on the
shellside.
The Twisted Tubes
themselves are round at each end, allowing for convenient
tube-to-tubesheet joints to be used.

Each tube is "locked" in place by the
six surrounding tubes. |

More
Efficient
Heat
Transfer |
Twisted Tube heat exchangers
provide a higher heat transfer coefficient than
any other tubular heat
exchanger.
Here's
why: |
- Complex swirl flow on the
shell side induces the maximum turbulence to
improve heat transfer.
- Powerful tubeside
turbulence is achieved even at high viscosities
and/or low velocities.
- Uniform flow distribution
gives more effective length and surface area
than other shell & tube
exchangers.
