Demand Control Ventilation (DCV)



Demand Control Ventilation (DCV)

Demand Control Ventilation is programmed automation of ventilation equipment to modulate the volume of fresh air taken in to match cooking demands.  Temperature sensors in the hoods' capture area respond quickly to adjust airflow. This unit is a method of ensuring a building is ventilated cost effectively while maximizing indoor air comfort.

Air Cleaning Technology offers cost efficient Demand Control Ventilation Systems.

System Features

  • Will modulate fan speed based off cooking temperature through temperatures sensors located in the roof of the canopy
  • Easily installed into any manufactures hood
  • Utilizes Variable Frequency Drives (VFD) to modulate fan speeds
  • Incorporates automatic and manual ON/OFF capabilities
  • Utilizes 6 different custom programmable algorithms.
  • 100% Fan Override button
  • Connects to the fire alarm system for safety
  • Demand Control Ventilation (DCV) technology to save energy, reduce overall operating and upfront capital costs, just a 20% reduction in airflow volume can yield 45–50% in annual fan energy savings
  • Your return on investment will increase proportionally based on the size of the ventilation system, number of operating hours and airflow rates.
  • Many local, state and federal utilities offer energy efficiency incentives and rebates—increasing your ROI substantially. Even without rebates and incentives, the payback period is typically 12–48 months.
  • Multiple sensors inside the hood, allows the system to measure sensible heat coming off the cooking line with greater accuracy
  • Turns on only when cooking operations are detected and shuts off once cooking equipment has cooled off
