The WATT Fluid Applicator™ is a non-contact
oiling and coating process developed and patented
(U.S. Patent No. 5,314,119) by Kenneth R. Watt (former
president of Latanick Equipment, Inc.) The process
allows the application of liquids onto a passing
surface of material with a very high level of accuracy
regardless of the line speed or surface width.
How does it work?
The WATT Fluid Applicator™ design is based
on a tank that maintains an even fluid level and
a rotating brush with a fixed speed transferring
the layer of fluid from the pick-up roller onto the
passing surface. The contact between the pick-up
roller and the brush causes the fluid between the
two components to be "flicked" onto the
passing surface. There is no contact between the
rolls and the passing surface. The "flicked" fluid
forms a droplet pattern on the passing surface and
transforms into a very uniform coating by the coiling
All units are designed to contain over spray. The
brush is completely enclosed by a special shield
which protects the brush surface from the passing
How well does it work?
The WATT Fluid Applicator™ is not sensitive
to "particle" size and can apply fluids
with solid content so long as the particles are suspended
in the fluid. A programmable controller regulates
the pick-up roll;; gear motor, accurately controlling
the amount of fluid that is applied. This causes
uniform and repeated strip coverage.
What is supplied?
Included with the WATT Fluid
Applicator™ is a support frame (specific to customer's requirements), fluid tank/tanks with heating elements that closely control the temperature of the fluid, control panel that included programmable controller and temperature controllers. Start-up can commence after the piping and electrical connections are made.
The construction of the machine is designed to meet the tough environment of the ferrous and non-ferrous industries;. A 64-inch system, fully assembled, can weigh in excess of 8,000 pounds. The design and construction takes into consideration the safety aspects of the mill environment. Safety switches on the doors are provided to ensure that maintenance work is not performed on nth unit while the process is in operation. The design of the machine is such that minimal maintenance is required.
What types of fluids can be applied?
To this date, there is no answer. We continue to test
new fluids at customer requests. Currently we have
applied fluids from animal fat based oils on Pickle
Lines to water like oils and chemicals used in aluminum
and paper mills.
