    Imagine a world where your building breathes in oxygen. Where comfort meets air quality, and where energy is saved. It is the world where AHUs and PLC control systems are the starting point of everything in the domain of Energy management systems. 

    These AHU controllers (Air Handling Units) are the primary components of any new HVAC system. They serve as the lungs. But to make those lungs breathe better, smarter, and cleaner, you need a brain—enter the Programmable Logic Controllers (PLC).

    We at Messung Industrial Automation are not just manufacturing PLC automation systems. We engineer intelligence. Smart PLC control is our ambition, and we aim to revolutionize the way AHU controllers operate, using a range of technologies, including Modbus, MQTT, compact PLCs, or IOT-enabled PLC. 

    Let’s dive into the cool, clean world of HVAC automation powered by Messung PLCs.

    A PLC-based AHU control system is the ultimate HVAC master conductor. The flow, cooling, heating, and energy consumption of air are all controlled by real-time logic and precision through automation controllers. 

    Decision-making is the primary responsibility of a IoT enabled PLC (programmable logic controller), not just following instructions. Your AHU is designed to respond to data, adjust to changing surroundings, and function like a finely tuned machine with the help of intelligent controllers. 

    Whether it’s a mini PLC for a compact setup or a modular PLC for a multi-zone building, this IEC 61131-3 standard controller is the heartbeat of your air management system.

    Core Functions of PLC Automation in AHU Controllers Applications

    1. Sensor Integration

    Temperature, humidity, CO2, and differential pressure are all sensors that your AHU controllers are equipped with. When it comes to Energy management systems, PLC control systems are necessary for reading, interpreting, and operating raw data. 

    Our intelligent PLCs work together with sensors to capture every detail of your indoor environment. 

    2. Data Analysis & Decision Making

    After submitting the data, the PLC Automation magic begins. Our IEC 61131 based PLCs utilize advanced logic and maintain monitoring of variables such as: 

    • Room occupancy
    • Outdoor air quality
    • Return air temperature

    The intelligence in this scenario is not confined to automation alone it expands to the action of the PLC Control Systems. 

    3. Control Actions via Actuators

    Now let’s talk about the muscle of the operation. By utilizing PLC and Modbus TCP/IP, your automation controllers can dynamically control VFDs (Variable Frequency Drives) to regulate fan speeds while minimizing energy usage. 

    4. Actuated Dampers

    Want zoned cooling in your building? Each damper is given precise guidance on when and where it should be opened or closed by our compact PLC, down to the second. 

    5. Valves

    Our PLC automation system manages both hot and chilled water circuits, ensuring thermal comfort with accuracy. 

    6. Humidifiers & Dehumidifiers

    The effect of humidity extends beyond comfort to include health and processes. Regardless of the weather, our intelligent controllers ensure optimal levels.
