GD Waldner - Room Air Control Fume Hood
Fume Hoods are not standalone devices and form a critical part of the overall lab ventilation system. Proper integration between the hood controllers, room controllers, and building systems is essential for a safe and energy-efficient lab space. At GD Waldner, we have learned from decades of project experience and developed our own laboratory control that helps to create customer-specific, adaptable laboratory control systems with the highest degree of energy efficiency. The GD Waldner Airflow-Controller AC4 is the latest version of our laboratory control system. Demand-led air flow damper control provides for the energy-optimized operation of laboratories and thus maximum safety and efficiency, thereby helping us to create the labs of the future today.
The AC4 module records the individual exhaust air volumes of all the exhaust units in the laboratory and calculates a total air volume from this. Some of the key features include
- Minimum air changes per hour are regulated based on different operating statuses (e.g., daytime operation, night setback. Individual device exhaust volumes can be controlled based on this.
- Automatic alarm in case of deviations from the target values.
- Maximum energy efficiency through real-time Variable Air Volume (VAV) regulation.
The AC4 is capable of deteting and controlling the following parameters
- Target and actual values of the air flow dampers
- Motorized damper positions
- Error messages, operating statuses, and sash positions
- Temperature and air pressure
When the sash is closed, the extract air volume is automatically reduced and increased as required when the sash is open.
- Reduced energy consumption
- Optimized operating costs
A motion sensor monitors the sash of the fume hood. If no movement is detected in front of the fume hood within a specified period of time, the sash closes automatically.
- The highest safety standards in the laboratory, thanks to closed sashes
- The best energy savings in conjunction with the VAV extract air system (Airflow-Controller)
The room air exchange is regulated to a minimum value at night.
- Reduction in night operation to 100 m³/h
- Maximum energy savings
