Case 2: Energy Savings Using Heat of Compression dryer

Based on the analysis of actual operating data, inverter compressors were selected to optimize energy savings according to varying operating conditions. Additionally, a load control system was implemented to automatically shut down unnecessary machines during low factory loads, minimizing idle standby time. To maintain air quality while enhancing energy savings, heat of compression dryers were also introduced. By integrating these systems with the existing internal network, centralized management of operating conditions was achieved.

Background
The goal was to improve the energy efficiency of the compressor equipment. Additionally, there was a need to centralize the monitoring of the compressor's operating conditions using the internal communication network.

Solution
The introduction of inverter compressors and heat of compression dryers, along with the installation of a group control panel, enabled centralized monitoring of operating data.
(Installed equipment: 3 units of ALE160WV, 3 units of ED160W, and a group control panel)

Results
✔ Reduced electricity consumption by approximately 300,000 kWh annually.
✔ Achieved centralized monitoring by linking the air compressor Modbus to the factory's internal communication network system.
