Industrial Compressor Heat Recovery Control

Published on: October 30th, 2025 · Author: Mees Meyboom

Introduction

Thermal Energy Recovery From Industrial Compressors needs a strong controller. The Moduline L4 delivers stable, safe and efficient control in demanding industrial sites.

Why the Moduline L4 suits compressor heat recovery

Flexible IO for pumps, valves and sensors

Thermal Energy Recovery From Industrial Compressors needs many signals. Common elements include temperature sensors on oil circuits, pressure sensors on heat exchangers, flow sensors on water loops and digital alarms from the compressor.
The Moduline L4 supports up to eight Moduline IO modules. These modules allow you to mix inputs and outputs based on system needs.
For example:

  • Temperature and pressure sensors can connect to analog inputs.
  • Flow meters can connect through frequency inputs.
  • Pumps and valves can be switched or modulated using output modules.
  • Safety loops can be read via digital inputs.

All modules use automotive-grade SUPERSEAL connectors for a secure and sealed fit, which helps in dusty mechanical rooms. This modular approach makes it easy to change or expand the control system later.

Real-time logic with Simulink and Node-RED

Strong communication for industrial sites

Industrial sites often use several communication systems. The Moduline L4 supports this with:

  • 4 CAN 2.0B interfaces
  • 1 LIN interface
  • Ethernet (10/100 Mbps)
  • USB for local connections

Optional wireless features such as Wi-Fi, Bluetooth, cellular and GNSS expand the setup when remote access is needed. GOcontroll’s remote services include secure cloud communication, software updates, controller state monitoring and predictive maintenance support. These options help plant operators keep track of heat-recovery performance and prevent downtime.

Example workflow for compressor heat-recovery control

Below is a simple workflow for using the Moduline L4 in a Thermal Energy Recovery From Industrial Compressors setup:

Sensor reading

Temperature, flow and pressure sensors send signals to the input modules. The controller reads them at a steady rate.

Control logic

A Simulink model calculates heat input, flow demand and target temperature. It then adjusts pumps or valves to match system needs.

Safety handling

The controller checks pressure limits, flow status and compressor alarms. If something goes wrong, it shuts down parts of the process.

Monitoring

Node-RED shows the system state on a local dashboard. Operators can see compressor heat, water temperature and pump activity.

Remote support

When wireless options are installed, the controller sends logs to the cloud. This helps teams track long-term energy savings.
