Vari-Flow Air Management System

The Accurex Vari-Flow Air Management System utilizes strategically placed heat sensors to effectively monitor the cooking operation and quickly adjust airflow to meet the demand. Reducing energy during slower periods of the day reduces electrical energy consumption and decreases heating and cooling loads all significantly reducing operating costs.

Product Features & Advantages:

  • Increased Savings - Reduces airflow by 50% or more during idle cooking periods generating more electrical, heating and cooling savings
  • Five Times Quicker Response - Capture Tank Mounted Temperature Sensor responds up to 5 times faster than duct mounted temperature sensors
  • Exceptional Value - The Vari-Flow system is an all-around cost-saver considering upfront costs, maintenance and ongoing payback.
  • Space Pressure Control - The Vari-Flow system controls the supply air unit by sensing static pressure in the space, independent of the exhaust fan speed, to ensure proper room pressurization at all times. Proportional tracking is also available.
  • Noise Reduction – Decreasing fan speeds reduces kitchen ventilation system sound levels to improve customer and employee comfort.
  • Reduced Maintenance - less wear and tear on fan motors, belts and pulleys
  • International Mechanical Code (IMC) Compliant - Meets Code requirements to automatically start fans when cooking operations occur.
  • Intuitive Keypad Interface - To control fans, lights, manual override conditions and identify system events.
  • 100% Override - Pressing a button will increase fan speed to 100% for a preset period of time when desired.
  • Efficient - Achieves energy savings required by multiple energy and green building standards, including ASHRAE 90.1, ASHRAE 189.1 and California Title 24.

The charts below are an example of how the cooking load in a restaurant may vary throughout the day and how the variable volume system generates monetary savings.

Chart 1 Chart 2
Figure 1 — The cooking load throughout the day varies significantly. However, the kitchen only requires maximum ventilation for a small percentage of the day. The shaded area represents the savings potential for a variable volume system. The dashed red line is showing fan operation at 100% regardless of cooking load. Figure 2 - A variable volume system will track the cooking load (dashed red line) and vary the exhaust and supply ventilation. The area above the red line represents energy savings
