Foundation
The foundation must adequately support the weight of the compressor package, including vessels, oil coolers,
controllers, and all ancillary equipment. (See documentation for weight and dimension specications
A detailed general arrangement drawing is provided with all packages. This drawing details foundation type,
mounting foot locations, grouting, and anchoring methods for the specic package.
Vilter Mfg. recommends consulting a licensed architect to design a suitable foundation for the application.
Foundations must be built of industrial-grade materials and conform to the appropriate building codes.
Mount the unit in a location which allows adequate clearance around the unit for maintenance.
The unit may be top-heavy so caution should be taken when lifting and moving the unit; See the “Rigging and
Lifting” documentation provided with the unit.
The unit must be securely bolted to the foundation and shims should be used to level the unit for proper opera-
tion. Grouting must be used.
The compressor should be rmly mounted to the package; isolation dampers should not be used between the
compressor and the package frame.
Pipes and conduits are strictly “no step” areas and could be damaged if used as foot or handholds.
Adequately support pipes, conduits, etc. to prevent both transmission of vibration and failure due to stress at
the anges. Suction and discharge lines must be supported with appropriate pipe hangers to prevent their
movement if they are disconnected from the compressor package. (See Table 1 below for Unit Weights.)
In high-pressure screw compressor applications, package vibration and noise levels may be higher than those
found in standard refrigeration applications. In these cases, adequate foundation and proper installation are
vital to ensure trouble-free operation. Additional sound attenuation measures may also be needed.
