External Inverter Applications
In compressed air systems, energy costs account for more than 70% of the total operating cost. The external inverter applications we offer as Ercom Compressor optimize the operating regime of your compressor and provide significant energy savings.
Standard compressors consume energy by operating in load and unload cycles. During unloaded operation, compressed air is not produced, while the motor continues to consume 30-40% of its full power. Our external inverter systems adjust the motor speed according to air demand and minimize unloaded operating times.
How Does It Work?
The external inverter system regulates the speed of the compressor motor according to instant air demand. This reduces unnecessary energy consumption and ensures that the system operates more efficiently and smoothly.
Energy Efficiency
By controlling the load-unload cycle, energy losses caused by unloaded operation are reduced. This provides a fast and measurable decrease in energy bills for businesses.
Sample Savings Calculation
In a scenario where a 55 kW compressor operates 4,000 hours per year and remains unloaded for 30% of the time, approximately 66,000 kWh of energy may be wasted. With Ercom’s external inverter solution, an average saving of 20 kW per hour and approximately 80,000 kWh per year can be achieved.
Advantages
- Provides an immediate reduction in energy bills.
- Protects mechanical components thanks to soft start operation.
- Offers stable operation with precise pressure control.
- The investment cost usually pays back within 12-18 months.
- Provides low maintenance costs and longer machine life.
