Emergency Screw Compressor Replacement in Polyester Unit

1. Project Overview

• Industry: Petrochemical

• Application: Polyester Production Unit

• Original Equipment: VM45

• Replacement Model: CS50H

• Condition: 3.0 bar / Continuous Operation

• Date: 2021

2. Project Background

The client operates a polyester production unit requiring stable compressed air supply under continuous operation.

The system originally used a VM45 screw compressor, which failed due to improper operation. With no standby unit available, the failure directly affected production continuity, requiring immediate replacement.

3. Challenges

• Sudden equipment failure due to operational error

• No backup compressor available

• Production interruption risk

• Urgent need for replacement within a short time

• High cost and long lead time for original brand equipment

4. Our Solution
