Differential Pressure Sensor Based Vav Control System - China

Differential Pressure Sensor-based VAV Control System is suitable for a variety of walk-in type fume hoods.

The differential pressure sensor-based VAV control system takes the differential pressure between the inside and outside of the fume hood as a constant value to control the opening degree of damper.

The differential pressure sensor is used to measure the actual differential pressure value between the inside and outside of the hood.

Then, the measured differential pressure value is compared with the preset differential pressure value.

The opening degree of damper blades is adjusted to make the measured differential pressure conform to the preset differential pressure value through PID.

Regardless of the chances in sash height or in static pressure of ductwork, a constant differential pressure value is maintained between the inside and outside of the fume hood.

• Business Description: Established in 2016,E3 Green Technology Co,Ltd. is a high-tech enterprise that aids users in saving energy, boosting efficiency, and offers scientists an environmentally friendly and healthy working environment.
  
  We are dedicated to providing safe and energy-saving comprehensive solutions for HVAC systems in laboratories and clean factories.
  
  Having been engaged in pharmaceutical R&D for many years, members of the founding team understand the harm brought by unsafe laboratory environment to researchers, so they determined to solve the two major problems of safety and energy issues for laboratories.
  
  The project was initiated and put into R&D in 2014 - After three years of study on the four core demands of "safety, energy saving, intelligence, and modularization", the team yielded fruitful outcome in developing the Bernoulli Laminar Air-Curtain Fume Hood and E·FLOW Damper with independent IP rights, overcoming the problem of air stability of the air compensation fume hood, which has bothered the industry for decades, and solved the technical problem of control valves of the ventilation system requiring accuracy, speed, and stability.
