ALCO Bayonet and Stand Alone Tank
Heaters
ALCO Tank Heaters utilize Longitudinally
or Helically Finned Tubes instead of Bare Tubes. Finned Tubes are more
efficient than bare tubes.
The Finned Tubes are placed in the
direction of the tanks convective currents. The heated fluid closest to the
Finned Tube Heater rises to the top of the tank, and the cooler fluid at the
top of the tank falls to the bottom of the tank, along the outer periphery of
the tank. This fluid motion creates a thermosyphon affect. This thermosyphon
affect causes the fluid to be in constant motion, with no stagnant zones; this
keeps sediment in suspension, preventing build-up on the heating coils and the
bottom of the tank. .

Benefits of using ALCO Designed
Tank Heaters |
- More economical than Bare Tube Tank
Heaters.
- Increased Heat Transfer Area.
- Smaller, Lighter Design because of Increased
Surface Area of Finned Tubes.
- Ease of Installation and Maintenance.
- Low Tube Skin Temperature reduces Corrosion,
Scaling, and Contamination of Finned Tubes.

Horizontal
Configuration |
- Used in tanks with low fluid levels, example:
Working Day Tanks
|
|
Vertical Configuration
|
- High tank fluid motion due to thermosyphon
affect.
- High heat transfer rates.
- Heating Coils elevated above tank floor for
easy cleaning.
|
|
Bayonet Heaters |
- Mounts onto side of tank by a mounting
flange.
- Horizontal configuration.
- Can be removed from emptied tank for cleaning
without entering the tank.
