This airflow device maintains Constant or Variable volume airflow by accurately reading the external conditions to deliver the actual airflow required to condition critical areas. Very commonly used in laboratories, research facilities with high air changes and balanced pressurization. The device requires I/O signal as well algorithmic data transfer protocols from the building management systems as well loops to provide the required feedback. This device can work in both Constant and variable volume modes.
Generally used in laboratories, research centers, biosafety cabinets etc where maintenance of pressure, temperature, and airflow is optimum to keep the room/unit well-calibrated. These devices are sensitive and can react in a fraction of a second to the external signal that is being applied to react to an operation.
The Venturi Air Valves have become an important part of any lab design and with greater sophistication, these are expected to operate and communicate with a Building control management system. Available in many sizes (6, 8, 10, 12 inches) as well as additional fittings like re-heat transition, the silencer can also be provided. Currently, we are offering only low to mid-range pressure systems. (0.3-3″wg)
EB Venturi Air Valve is also largely considered for CAV applications for ventilation systems. Constant airflow can be maintained in critical parts of the CAV system by applying EB Venturi Air Valve with pressure-dependent capability. Actuators, Controllers can be ideally programmed to maintain the required set point operating condition. However, in general cases, EB Venturi Air Valve can be factory calibrated for set point airflow and adjusting the locked position of the valve come. By keeping that position EB AIR Venturi Air Valve (VAV) can maintain a constant flow at minor pressure fluctuations.
By incorporating Belimo NMQ24A-VST Actuator and VRU Universal Modular Controller in the Valve operations, direct communication can be established through BMS either MODBUS or BACNET. Through this real-time control, room pressurization can be maintained by controlling the Valve to maintain the desired airflow at any given pressure. In the EB Air case, the objective is to offer a robust controllable device that can operate, connect, and maintain the flow characteristic as required under given conditions. Read more.
These are series of damper assigned in a bank arrangement both horizontally/vertically to cover a required opening area. The main advantage of damper bank is control as well shut off flow of a larger area. Damper bank can also be synchronized to modulate flow [...]
Everything you need to know about the Tall Boy Induction Unit (TBY) A tall boy induction unit is installed in taller locations where the width is less. Enclosures with more height generally use tall boy systems to fit in the location. They [...]
