AHU (VFD) Control Panels: Precision Airflow, Optimal Efficiency, Superior Comfort

Elevate your Air Handling Unit (AHU) performance with our advanced AHU (VFD) Control Panels. Designed for ultimate control, energy efficiency, and operational reliability, these panels integrate cutting-edge Variable Frequency Drive (VFD) technology with intelligent control systems to optimize your building's indoor environment while significantly reducing energy consumption.

Overview

Our AHU (VFD) Control Panels are comprehensive, pre-engineered, and pre-wired solutions that provide precise speed control for AHU fans. By adjusting fan speed based on real-time demand (e.g., temperature, pressure, CO2 levels), the VFD ensures that your AHU operates only as hard as necessary, translating directly into substantial energy savings, extended equipment life, and enhanced occupant comfort.

Key Features

• Integrated High-Efficiency VFD:
  • Premium brand VFDs (e.g., Siemens, ABB, Danfoss, Schneider Electric) for reliable and precise fan speed control.
  • Advanced motor control algorithms for optimal efficiency and performance.
  • Built-in EMI/RFI filters and DC link chokes (optional) for power quality compliance.
• Intelligent PLC/Microcontroller:
  • Programmable Logic Controller (PLC) or advanced microcontroller for robust, customizable control logic.
  • Pre-programmed with standard AHU sequences (e.g., start-up, shut-down, frost protection, fire alarm integration).
  • Capable of handling complex control strategies based on various sensor inputs.
• Intuitive Human-Machine Interface (HMI):
  • User-friendly touch screen HMI for local control, monitoring, and alarm management.
  • Displays real-time operational data (fan speed, current, power, temperatures, pressures).
  • Allows easy adjustment of setpoints, scheduling, and operational modes.
• Comprehensive Motor & System Protection:
  • Overload, short circuit, over-voltage, under-voltage, and phase loss protection for VFD and motor.
  • Thermal protection for motor windings (via PT100/Thermistor inputs).
  • Fuse or circuit breaker protection for all circuits.
• Seamless BMS Integration:
  • Multiple communication protocols supported (e.g., Modbus RTU/TCP, BACnet MS/TP, BACnet IP, LONworks).
  • Facilitates remote monitoring, control, and data exchange with Building Management Systems (BMS).
• Robust & Safe Enclosure:
  • High-quality, durable sheet metal enclosure (mild steel, stainless steel optional) with appropriate NEMA/IP rating (e.g., IP54, IP65).
  • Proper ventilation and cooling for internal components.
  • Lockable door with emergency stop button and external indication lamps.
• Sensor Inputs & Actuator Outputs:
  • Dedicated inputs for temperature, humidity, pressure (static, differential), CO2 sensors, fire alarms, filter status, damper positions.
  • Outputs for fan start/stop, damper actuators, heating/cooling valves, frost heaters, etc.
• Diagnostic & Alarming Capabilities:
  • Detailed fault codes and alarm logs for quick troubleshooting.
  • Configurable alarm outputs (local indication, BMS integration, SMS/email alerts optional).

Key Benefits

• Significant Energy Savings: Reduce fan energy consumption by up to 50% or more by matching fan speed precisely to airflow demand.
• Precise Airflow & Pressure Control: Maintain optimal room conditions, static pressure, and air quality with intelligent, adaptive control.
• Enhanced Indoor Air Quality (IAQ): Integrate CO2 and humidity sensors for demand-controlled ventilation, ensuring fresh and healthy air.
• Extended Equipment Lifespan: Soft start/stop capabilities of the VFD reduce mechanical stress on fans, motors, belts, and bearings, leading to longer operational life and lower maintenance costs.
• Reduced Noise & Vibration: Smoother motor operation at lower speeds translates to quieter AHU operation.
• Lower Maintenance: Fewer wear-and-tear components due to optimized operation.
• Centralized Control & Monitoring: Integrate seamlessly with your BMS for comprehensive facility management.
• Customization: Tailored solutions to meet specific AHU configurations, control philosophies, and building requirements.
• Compliance & Safety: Designed and manufactured to relevant international standards (e.g., IEC, UL, CE) with robust safety features.
