We would like to introduce the terminal unit 'VAV/CAV' handled by Cliff. The differential pressure type air velocity sensor is one of the standard flow meters, featuring a simple structure and high reliability. For general air conditioning, the conventional functions have been upgraded. The airflow control range has been expanded, standard implementations of previous options have been included, and a structure that eliminates electrical components within the unit has been realized for increased longevity. The usability for monitoring status and changing parameters via a dedicated setting device has been improved. 【Features】 ■ Compatible with various communication standards such as DDC, LonWorks, and Modbus ■ Customizable to meet various requests ■ Capable of accommodating various materials, irregular sizes, and large sizes Example) Large units - Airflow in the duct can be averaged and controlled with a single measurement controller using an averaging pitot tube. *For more details, please refer to the PDF document or feel free to contact us.

The "KND Series" is a manual airtight damper suitable for fumigation. By closing the damper blades, it effectively blocks gas with very high airtightness. There is zero leakage from the damper casing and the shaft penetration. The valve section, bearings, and operating mechanism are treated to be dustproof and rustproof, allowing for safe use even in dusty and humid environments. 【Features】 ■ Zero leakage in the airflow direction when closed (within 3 kPa pressure) ■ Zero leakage from the damper casing and shaft penetration ■ Can be installed in any wind direction: horizontal, upward, downward, or diagonal ■ The closing mechanism can be easily and securely operated with a one-touch lever handle ■ Connection flanges are available in round and square shapes ■ Highly suitable for fumigation *For more details, please refer to the PDF document or feel free to contact us.

"Eco Wind" is a natural ventilation device that utilizes the energy of natural wind. It detects the outside wind flow using a wind speed sensor and controls the amount of wind intake by opening and closing the blades. It safely and directly brings in fresh outside air. During the intermediate seasons of spring and autumn, as well as summer nights, it only takes in outside air when the temperature is within the set range, using external temperature sensors. Additionally, in strong winds or rain, it disables natural ventilation through wind speed sensors and central monitoring, blocking outside air with a forced full closure command. 【Features】 ■ CO2 reduction ■ Energy saving ■ Natural ventilation *For more details, please refer to the catalog or feel free to contact us.
