Detail Specification of Marley Cooling Tower Drift Eliminator model TU-12X
Hello ritaritz, I contacted Marley and they e-mailed a 2 page spec
sheet which is in a .pdf file (requires Adobe Reader). I also called
Marley (800)462-7539 and talked with Teresa. The "TY-12X" is the
crossflow product and the "TD-12C" is the counterflow version. Both
are furnished in 5.75 inch thickness X 9.6/12.2/24 inch widths X 144
inch length. Here is the text from the spec sheets:
Marley developed the first cellular drift eliminator over 20 years ago
when eliminator designs were primarily blade type configurations and
not very effective. Next, Marlet patented the XCEL generation of
eliminators in the early 80's. No other eliminator could come close to
XCEL eliminator's low drift rate and low pressure drop. Now, virtually
every eliminator is a nesting cellular PVC type design. Introducing
XCELplus, a more advanced design that meets or exceeds today's
demanding specifications for drift emissions, without sacrificing fan
horsepower. Now you can have drift rates half of the original XCEL
with equivalent pressure drop. The eliminator discharge angle is
important enough to warrant two seperate eliminator designs-one for
crossflow and one for counterflow towers. Tests show that the air
direction leaving the eliminator is extremely important-imperfect
designs create additional work for the fan. This means either
increased fan horsepower-or reduced cooling tower performance. The
crossflow version features drainage slots within the eliminator pack
to insure trapped drift is returned to the wet side of the cooling
tower. Low drift rate is the primary goal of eliminator design.
XCELplus boasts typical drift rates of .001% of the total GPM. Drift
rates of .0005% and lower are available depending on tower
configuration. Drift rates with the original XCEL elininator were so
low that a better measurement method than the Sensitive Paper
Technique was required. The Hot Bead Isokinetic Drift Measurement
(HBIK) method pionered by Marley over 20 years ago, is now the
endorsed CTI standard test procedure, ACT-140 for drift measurement
today. Considering low drift rates and low pressure drop, XCELplus is
the most effective cooling tower drift eliminator available in the
market place today.
SUGGESTED SPECIFICATION:
Drift eliminators shall be of cellular type, Marley XCELplus or
approved equal. The eliminators shall be thermoformed from 17 mil
(.017 inch) PVC (polyviny chloride) into a configuration providing at
least 3 changes in air direction and solvent welded into multiple
sheet packs. Eliminators used in crossflow towers must provide a
discharge angle (as defined by the last section of the eliminator
itself) of at least 42 degrees from the horizontal when installed. The
mass drift quantity, determined by the CTI Drift Test Code ACT-140
shall not exceed ____ % of the total GPM and shall be guranteed for
all operating conditions. The eliminator packs shall be able to span
66" unsupported for counter flow configurations and 72" for crossflow,
with minimal deflection at design conditions. Eliminators shall be FM
approved. Eliminator packs shall measure up to 24" wide, 5.75 in
depth, and up to 12'-0" long.
Sorry I can't show you the pictures here. You can contact Marley and
get the .pdf file like I did. I could e-mail the file to you, but it
is not wise to post your e-mail address here. Here is contact info for

Hope this is what you are looking for, Redhoss
The information I requested is for TU-12X and not TY-12X or TD-12X. Please clarify.
I am not a very good typist and was very embarrassed to read that
first paragraph just now. Also, I am usually a better proof reader.
The "TY-12X" should read "TU-12X" and the "TD-12C" should read
"TU-12C". Wow, I hope I didn't make any other errors like this. I had
to type this whole answer since I couldn't copy text off the Adobe
window. Sorry for the miscue.
TU-12X for cross flow and TU-12C for counter flow. The figure 12
could mean 12' long. There is another model TU-6x and TU-6C for 6'
long.
Please clarify: Is XCELplus the brand name of TU-12X/TU-12C for 12'
long and TU-6X/TU-6C for 6' long? Since you already talk to Teresa of
Marley, please call her again for this information so there is no
duality. Please request specific spec sheet for TU-12X for physical
property and dimension. View NIT Details::
