Equipment Skids & Base Frames – Engineering Execution & Field Services
Equipment Skids and Base Frames are engineered structural platforms designed to support HVAC and process equipment safely, maintain alignment, absorb operational loads, and ensure long-term structural stability.

They are commonly used for:
- Chillers
- Primary & secondary pumps
- Cooling towers
- AHUs (Air Handling Units)
- Heat exchangers
- Compressors
- Utility equipment packages
- Packaged skid-mounted systems
Improper base frame design can result in:
- Vibration transmission
- Equipment misalignment
- Structural fatigue
- Anchor bolt failure
- Uneven load distribution
- Premature equipment wear
Compress India provides complete engineering execution services including structural design, load calculation, fabrication, anti-corrosion treatment, installation, grouting, alignment, retrofitting, repair, and AMC services.
Why Proper Skid & Base Engineering Is Critical
Equipment foundations must account for critical load factors to ensure operational safety and longevity.
Critical design considerations:
Static load (equipment weight)
Dynamic load (operational vibration)
Rotational imbalance forces
Seismic considerations (where applicable)
Thermal expansion factors
Anchor bolt pull-out resistance
Benefits of well-engineered base frames:
Stable equipment performance
Reduced vibration transmission
Accurate shaft alignment
Long-term structural durability
Maintenance accessibility
Extended equipment lifespan
