  • Design flexibility and customisation

Ideal for Critical Spaces, Hospitals
and Laboratories

The Variable-Air-Volume (VAV) Airflow Control Boxes are the most critical element for achieving stringent Laboratory performance integrity. Our Laboratory Controls Solution are as follows:

The VAV Controller:
RC-FLEXair Advanced VAV Controller

  • Built-in differential pressure sensor for above airflow measurement shall be of high accuracy & high performance type, for full range of ±500Pa (±2” WC) with 0.122Pa (0.005” WC) resolution

  • Configurable P, PI, or PID controls for closed loop control

  • With Standalone Realtime Airflow Measurement, Feedback, Control & Monitoring, Scheduling, Trend Logging 

  • BTL Listed BACnet® Building Controller (B-BC). The highest BACnet DDC Controller profile, with best interoperability.

  • BACnet TCP/IP based VAV Controller for fast response communication and control between VAV Controllers and Master Controller or Building Management System (BMS)

  • Integration with SMART-Net™  Indoor-Air-Quality (IAQ) Sensor – Temperature / Relative Humidity / CO2 / VOC / Occupancy / PM2.5

  • Ultimate flexibility – multiple universal inputs / outputs (DI, AI, DO, AO) options, configurable for Heater Control, IAQ Fresh Air Control, Fume Hood Control,  Alarm Monitoring and etc.

The VAV Airflow Control Box:

  • Probe-less Venturi airflow measurement method, Accuracy of ±5%, throughout the entire range from maximum to minimum airflow (as low as 1Pa at very low flow)
  • High Airflow Turndown, minimum 10 to 1
  • Maintenance Free
  • Pressure Independent Control
  • Low Pressure Drop
  • ETFE Coating for Corrosive Environment Application

Additional Features of VAV Controller:

  • Lighting-fast triple-core, 32-bit processor and dual 10/100
    Ethernet ports

  • Powerful & nearly unlimited data processing power & handling on the most demanding programmed sequences, performance tracking and data analysis.

  • Backward compatible, future ready

  • Convenient access through USB application port

  • Reference to ASHRAE Guideline 36-2018, High Performance Sequences of Operation for HVAC (VAV) Systems

  • Accessible through myControl Mobile Apps for remote access for control & monitoring

  • Smart Lab / Smart IBMS integration ready


Lab Controls Solutions

  • Safe and energy efficient
