By changing the air volume adjustment from traditional damper opening and closing to inverter control, power consumption is reduced.

By changing the air volume control from traditional damper opening and closing to inverter control, we can reduce power consumption. The duct damper can be fully opened, allowing for easy switching of the fan motor speed with a manual switch on the control panel. It can quickly respond to changes in store congestion and seasonal conditions with the set speeds on the step speed switch. 【Features】 ○ Control Method: Simplified operation with manual step speed control ○ Target Equipment: In-store air conditioning units 　　　　　　Air conditioning unit fan <Air Handling Unit> (30.0 kW) For more details, please contact us or download the catalog.
