Variable-frequency series

1. By controlling the rotational speed through the frequency converter, a more efficient control of the variation range of exhaust pressure is achieved, with the pressure variation being approximately 0.01 MPa. This reduces the exhaust pressure and saves power consumption.

When the load rate is 60%, it saves approximately 14% compared to the two-stage control type.

2. With the unique APC (Active Power Control), better energy conservation is achieved. The unique APC function utilizes a fixed end pressure to achieve better energy savings.

When the load rate is 60%, compared with the two-stage control method, it can save approximately 25%.
