Installation Considerations
Thorough application review should be conducted before, during and after installation:
Determining Omnicell Capacity - Sizing the Omnicell (general rule) – Take
the overall live and dead load of the vessel. Multiply by 2, then divide by the
number of support points (legs, typically). For example:
4 Legs
26,000 lbs – dead load
74,000 lbs – live load
26,000
+ 74,000
100,000
x 2
200,000
÷ 4
50,000 lb for
each Omnicell
Loading – The vessel will have 3, or more, tank legs. The Omnicells should be
level and, under extreme cases, shimmed, so that the load is roughly equal on
each Omnicell.
Flooring - A thorough inspection of the flooring’s deflections must be considered
before installing an Omnicell system. Flooring must be rigid enough to handle the
total load without deflection.
Thermal contraction and expansion – Horizontal vessels, in direct sunlight,
can create thermal expansion issues. The floating rocker column design of the
9120 Series Omnicell easily handles most thermal expansion/contraction issues.
Uplift and lateral constraints – In extreme conditions (high winds or seismic
activity) uplift and lateral stresses on the Omnicell system are a concern and
should be considered when choosing the best Omnicell for the application. The
9120 Series Omnicell provides a degree of built-in uplift and lateral checking,
refer to the product QuickFacts for a detailed explanation of the forces. In
extreme conditions, additional checking is recommended.
Isolate vessel – Many external factors affect the accuracy and stability of
an Omnicell system. Load cell signals can be affected by EMF sources such as
electric forklifts, pumps, motors, etc. A well-isolated tank will provide more
reliable results with fewer problems.
