DESCRIPTION

Airflow measurements is a critical component of energy efficient HVAC system performance. Airflow measurement is a key factor in assuring that HVAC systems are providing optimum occupant comfort, at the lowest possible energy cost.
 
Kyllor has developed technology, which provides:
  • Certified Installed System Accuracy
  • Substantially lower Installed System Cost
Kyllor is dedicated to meeting the needs of building owners, BAS providers and mechanical contractors, as they endeavour to provide “Greener” HVAC systems.

APPLICATION

Kyllor airflow measurement system applies to:
  • Supply and return fans
  • Compartment fans
  • Building exhaust and ventilation fans.
Kyllor technology offers accurate airflow measurement for:
  • Indoor air quality
  • Demand-based ventilation control
  • Other processor control applications.
HVAC system Commissioning time…Cost…is significantly reduced.
 
Accurate real time airflow measurement of fan systems provides a solid base for verification of air balancing process.
 
Building operations are improved considerably with immediate access to airflow data;
 
Application engineering of the Kyllor system is quick and easy.

FEATURES
Certified Installed System Accuracy
 
Kyllor innovative airflow measurement technology provides Certified Installed System Accuracy of ±3% of design flow. This is unique in the HVAC industry. An optional ± 2% accuracy is available.
 
Kyllor technology offers an airflow measurement solution, which is not dependent on locating Laminar flow. Sensor location is easily established.
 
Reliability
 
Kyllor airflow measurement system's unique design assures long-term operating stability, even in the toughest environments. Airborne particulate is not an issue.
 
Reliability of competitive systems is substantially reduced by particulate contamination of the sensitive thermistor sensors.
 
Providing the highest standard components, the Kyllor system assures years of reliable operation.
 
Adaptability
 
Kyllor technology can accommodate the most complex duct systems. Laminar flow sections are not required. Kyllor easily accommodates multiple supply duct branches emanating from fan discharge.
 
Kyllor technology provides BAS network connectivity with major network protocols.
 
Simplified Operation
 
Digital display of airflow is operator selectable either in cubic feet per minute (cfm) or cubic meter per minute (cmm). The digital display presents airflow data in an understandable manner.
 
Kyllor airflow measurement system can be installed easily and integrated with various building automation systems. The shorter installation time puts Kyllor ahead of competitive systems.
 
 
Cost Effectiveness
 
The installed cost of Kyllor airflow measurement system is lower than competitive systems. When both supply and return airflows are measured by the Kyllor Dual Airflow station the installed system cost is substantially lower than competitive systems.
 
Commissioning time and costs are significantly reduced for all parties: Design Engineers, BAS contractors, and commissioning agents.
 
Kyllor system is maintenance free, which reduces operating expenses.
 
Where competitive systems use more sensors for greater accuracy, Kyllor requires only one set of sensors.
 
 
Warranty
 
A 24 months warranty applies from the date of shipment. Replacement parts are shipped within 48 hours.
SAMPLE PROJECT SPECIFICATION
  1. Airflow Measurement Technology shall be provided as manufactured by Kyllor. Alternate airflow measurement technology may be provided only if the Installed System Accuracy of ± 3% of design flow is site certified by supplier.
  2.  
  3. Airflow Measurement Station shall be located as indicated on the drawings.
  4.  
  5. The Installed System Accuracy must be certified by the manufacturer as to ± 3% of 100% design flow.
     
  6. 1. Airflow Measurement Station shall operate on externally provided 24VAC, 40VA power supply.

  7. 2. Electronic components shall be housed in NEMA 4 enclosure for protection against water damage.
    3. Digital display of airflow shall be operator selectable as either cubic feet per minute (cfm) or cubic meter per minute (cmm).
     
  8. When alternative airflow measurement station is used, then maintenance service and installed calibration verification shall be provided by supplier for the first 2 years of operation.
  9.  
  10. Airflow Measurement Station interface to the BAS shall be as agreed to with BAS provider. The standard BAS hardware interface shall provide an analog signal for flow as 0-10 VDC and 4-20mA. Optional network protocols shall provide data points for airflow, fan head pressure and fan status. Selection may be any of the following:
  11. - BACnet®
    - TCP/IP
    - LonWorks® Free Topology
    - Modbus
     
  12. The system operates continuously in temperature range of –25°C to 85°C (-13°F to 185°F), and humidity range of 0 to 99%.
  13.  
  14. Storage temperature range of 0°C to 50°C (+32°F to 122°F) shall apply.
