Installation
Application Evaluation
The UltraDoser 2K can be used for both inerting and pressurization applications. The application must be
evaluated to determine the ideal location of the dosing head on the filling line.
Inerting – Inerting is the process of removing oxygen (O
2
) from a bottle (or container) by dosing
a relatively large amount of LN
2
in the bottle (or container) to inert. The liquid dose quickly
converts into gas displacing air and oxygen from the bottle (or container). The ideal location for
the UltraDoser unit must allow for enough time between dosing and capping so that the liquid
dose is converted into a gas.
Pressurization – Pressurization occurs by dosing a relatively small amount of LN
2
into a bottle
(or container). The liquid dose quickly converts into gas and the bottle (or container) is then
capped or sealed to capture the expanding gas. The UltraDoser unit should be installed as close to
the capper as possible.
Support Stand Location
The UltraDoser unit is supplied with a mounting bracket assembly. The assembly
consists of the bracket attaching to the UltraDoser body and two clamps designed to fit on
1½”stainless steel rod. Chart can supply a prefabricated stand to accommodate the
mounting bracket assembly. This stand can be utilized in almost all installations. If the
Chart stand cannot be used in your installation, fabricating one with 1½”diameter rod or
round bar will make installation of the UltraDoser 2K simpler. The following instructions
will assume installation of Chart’s prefabricated support stand (Figure 4).
1. The UltraDoser unit can be installed on either side of a production line. Select the side that best
suits the workplace. The mounting bracket assembly is installed straight back opposite to the arm
from the factory. However, the UltraDoser body can be mounted in the mounting bracket such
that the support stand is located on either side perpendicular to the arm (Figure 1-3).
2. Measure the appropriate distance depending on the UltraDoser configuration. This is the location
for the installation of the support stand.
3. Mark the location of the stand and install the four (4) 5/8” bolts included with the support stand in
the proper locations.
