Screw Compressor Replacement in PP Pneumatic Conveying System

1. Project Overview

• Industry: Petrochemical

• Application: Polypropylene (PP) Pneumatic Conveying System

• Original Equipment: VM100

• Replacement Model: CS130H

• Operating Condition: 2.25 bar / Continuous Conveying

• Date: 2025

2. Project Background

The client operates a polypropylene production unit with a pneumatic conveying system requiring stable and continuous air supply.

The original system used a VM100 screw compressor, which needed replacement to ensure long-term stability and maintain system performance under continuous operation.

3. Challenges

• Requirement for strict parameter matching in conveying system

• Need to ensure stable airflow and pressure control

• Risk of system instability if replacement is not accurate

• Dependence on original equipment for spare parts and maintenance

• Requirement for seamless integration without system modification

4. Our Solution

Procetek provided a CS130H oil-free screw compressor, designed for conveying system applications:

• Fully matched flow, pressure, and power parameters

• Direct replacement without pipeline or system modification

• Stable airflow delivery for conveying process

• Reliable performance under continuous operation

5. Scope of Supply

• Oil-free screw compressor

• Procetek Model: CS130H
