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 portsPowerful & 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
