Tank Heating Eductors (aka Sparger Nozzles)

• Computer optimized flow paths enable the Jacoby-Tarbox eductor TLA to maintain a high "pick-up ratio" (the ratio of fluid entrained to the motive fluid) while maximizing the hydraulic efficiency (the ratio of hydraulic power at the outlet of the TLA to the hydraulic power at the inlet) to generate an optimum flow field from the greatest flow amplification.
• No moving parts in the sparger nozzle, minimizing maintenance expenses.
• Optimum flow field enables more activity within the tank than competitive units without changing pumps.
• Compact design and ease of mounting keeps the TLA from interfering with other tank equipment.  
• "In-tank" mounting eliminates need for costly, complex mounting structures above tanks.   
• The TLA can be used in a wide variety of open vessels or closed tanks. 
• Eliminates stratification and promotes a homogenous tank with relation to pH, temperature, solids or gas dispersion, and distribution of chemicals.
• Produces a unique agitation not available with other types of mixers, as the TLA can generate a directed flow field within the fluid being mixed including viscous fluids, slurries, and suspensions.
• Easily mixes liquids of differing specific gravities and is excellent for scrubbing applications where a lower specific gravity fluid is driven into the higher one.
• Flow amplification due to high "pick-up ratio" and hydraulic efficiency permits the use of smaller pumps, which translates to reduced costs of mixing or agitation.
• Reduces investment cost because existing transfer pumps can be utilized for more than one purpose.

• Excellent Corrosion Resistance
• Excellent Abrasion Resistance
• 300° F Continuous Service
• Good Non-Stick Characteristics
• Excellent Dielectric Insulation
• Radiation Resistant

This coating is applied via electrostatic powder spray or fluidized powder bed. In addition to possessing the high chemical and temperature resistance which all fluoropolymers are noted for, Edathon's strengths, radiation resistance, wear resistance, and creep resistance are significantly greater than those of other fluoropolymers such as PTFE, FEP, or PFA.

The standard Jerguson/Jacoby-Tarbox models for heating in vessels are the TLA and ULJ. The model TLA is well suited to providing strong tank agitation while heating. Compared with other heaters, the cost per application is small. The model ULJ is designed to provide vigorous circulation of the liquid with low pressure steam inputs.

Sparger Nozzles should be located with the outlet pointed toward the most remote portion of the tank to provide the best agitation possible.

Information needed to size includes the following:

• The liquid in the vessel is Water (Sg =1.0)
• The temperature rise desired is ΔT = 50°F
• The final tank temperature is 120°F
• The vessel holds 550 gallons
• The time to heat it is 20 minutes
• Steam is available at 40 psig
• Use two model TLAs

Standard materials TLA's are cast or fabricated in: bronze, 316 stainless and carbon steel. Cast units range from IPS 3/4 to 2. Larger sizes and other materials are fabricated. Consult the factory for details.

Standard body connection for 3/8 and 3/4 units is male NPT and for 1-1/2" through 3", female NPT. Over 4" is flanged. Optional connections include female/male NPT, butt weld, socket weld, VictualicTm, sil-braze, and flanged.
