Infilex™VN Venturi Valve for Variable Air Volume

Infilex VN Venturi Valve for Variable Air Volume

Infilex VN is a venturi valve combined with an airflow controller, designed to control airflow rate/room pressure in research facilities, fabrication facilities, and hospitals.
Infilex VN directly communicates with our building management system (BMS) savic-net™FX via LonTalk® protocol. This enables you to supervise airflow volume and status of fume hood exhaust, general exhaust, and supply air from savic-net FX center unit (client PC).

Pressure-independent mechanism:
The valve performs self-balancing operation to maintain a fixed flow of air by adjusting to changes in duct static pressure.

Quick response:
High-speed electric actuator mounted onto the valve quickly responds to the changes in airflow command.

Zone Presence Sensor

Venturi Valve for Constant Air Volume

Zone Presence Sensor Model ZPS2XX detects the presence of personnel in front of the fume hood.

When an operator is present:
Zone Presence Sensor sends signal of standard mode (standard flow, 0.5 m/s face velocity for example) to the venturi airflow control valve Infilex VN.

When an operator is absent:
Zone Presence Sensor sends signal of standby mode (lower flow, 0.3 m/s face velocity for example) to the venturi airflow control valve Infilex VN in order to save energy.

    savic-net FX Research Environment Management Server

    savic-net FX Research Environment Management Server

    savic-net FX Research Environment Management Server is a management support server to understand the operational condition of the laboratory and promote energy-saving measures and safety control. It provides the lab with an effective operation through mutual participation of researchers who use the lab, and Environmental Safety Manager and Building Manager who are engaged in operational management of the lab.
    It provides information for energy conservation, safety control, and the appropriate facility planning, using data a venturi valve with airflow controller (Infilex VN) holds.



    Features

    • Energy saving
      It monitors the status of use and the exhaust airflow of a local exhaust ventilation device such as fume hood, supporting its energy efficient operation by quantifying energy loss for each lab or each fume hood.
      It optimizes operation and helps reduce the energy consumption of the facility with an effective use of the venturi valve with airflow controller (Infilex VN).
    • Safety control
      Monitoring of the maximum exhaust airflow enables you to obtain the extra capacity (safety margin) of the exhaust ventilation system. Also, the optimized operation can make the safety margin bigger, i.e. the difference between the actual airflow and the ideal airflow. An effective use of the venturi valve with airflow controller (Infilex VN) quantifies the safety margin and enhances the safety capability of the facility. It supports safety control by researchers through mutual monitoring combined with historical management of the equipment error alarm.
    • Facility planning
      Those who are engaged in operational management of the lab, such as researchers, Environmental Safety Managers, or Building Managers can share all the information via intranet. You can mutually understand how safe or energy efficient your lab is by accessing the research environment management server from your PC via intranet.
    • Information sharing
      Information sharing among those who are engaged in operational management of the lab, such as researchers, Environmental Safety Managers, or Building Managers allows you to analyze the status of use and the exhaust airflow of the fume hood and to prepare a facility plan based on the actual data. The server provides you with airflow data required to understand the impact of addition or relocation of a fume hood to the related exhaust ventilation equipment, achieving facility planning in line with the actual operational conditions of your facility.
