PLC Chiller Control

Introduction to

Our PLC & HMI Chiller and Refrigeration Control Solutions

With extensive experience in refrigeration engineering, we specialize in designing and developing advanced Programmable Logic Controller (PLC) & Touch Screen Control Systems, refrigeration parts supply, and expert consultancy. We have successfully executed projects, including new installations and retrofits, for industrial factories, commercial buildings, hotels, and food processing plants. Our solutions are engineered to maximize efficiency, optimize performance, and enhance sustainability.

Why Choose PLC & HMI Control?

Precision Temperature Management
Our PLC programs continuously interpret data from temperature, pressure, and flow sensors—then automatically adjust compressor staging, evaporator fans, and expansion valves to maintain your setpoints within ±0.1 °C, ensuring optimal product quality and extended shelf life.
Energy Optimization
Leveraging adaptive PID loops, variable-frequency drives (VFDs), and intelligent scheduling (including night-setback modes), our control strategies can cut runtime and power consumption by up to 20 %, lowering your operating costs.
Intuitive Operator Interface
Customizable HMI screens give operators a clear, at-a-glance view of the entire system. Dashboards, trend graphs, and alarm logs are accessible on-site via touchscreen or remotely through a secure web portal—empowering faster decisions.
Scalable & Future-Ready
From compact single-panel controllers to distributed networks across multiple sites, our modular architecture scales with your business. Easily integrate new equipment, connect third-party sensors, or expand into full IoT-based monitoring.
Robust Safety & Diagnostics
Built-in fail-safes, high-precision diagnostics, and proactive alerting safeguard your equipment. Automated shutdown sequences, refrigerant leak detection, and guided troubleshooting minimize unexpected downtime.
