Every project — from a single compressor swap to a full plant overhaul — follows the same disciplined engineering sequence.
01
Site Assessment
On-site audit of existing compressors, piping, controls, and plant performance data.
02
Engineering & Design
Retrofit design, load calculations, and spare-part / overhaul scope tailored to the plant.
03
Procurement
Sourcing of genuine and high-grade compressor parts, packages, and controls hardware.
04
Installation & Overhaul
Mechanical and electrical execution with planned downtime and laser-aligned drives.
05
Commissioning & AMC
Startup, performance testing, handover, and ongoing maintenance support.
