Powerful drives for power generation !
CG Drives & Automation has been working with the energy sector for many years. Our robust and powerful AC drives offer efficient and reliable operation of your pumps, fans and cranes. You will save energy, maintenance and downtime costs.The range covers motor powers of up to 3,000 kW at 690 V mains supply.
Keep up pressure and save energy.
Introducing speed control will maximize output from your pump and fan systems. It will reduce energy consumption and mechanical wear as well as noise and vibration levels. Operation is continuously adapted to demand, maintaining the required pressure depending on volume flow or the quantity of gas to be handled. A sleep function saves further energy by stopping the motor when it does not need to be run to keep up the pressure.
Controlled starts and stops reduce wear.
Low start currents reduce hydraulic and mechanical stress on pipes and gaskets. Linear stops eliminate the risk of water hammer in your pumps, without the need for costly motor-controlled valves to reduce pressure spikes. Starting a fan that is rotating the wrong way is handled safely with a spin start function securing the correct direction and function before full speed operation.
High dynamics for demanding applications.
Our AC drives also offer high accuracy in dynamic applications, for example cranes used in biofuel-fired power plants. Efficient and precise control minimizes cycle times and mechanical wear. Direct torque control handles abrupt load changes and overcomes initial peak loads. Electronic grab control coordinates the drives and allows for motions to be manoeuvred independently. The operator can close or open the grab while it is being hoisted and lowered, reducing cycle times and wear to the ropes.
Protection against damage and downtime.
A built-in load monitor prevents damage and downtime, for example if a pump is running dry, a pipe is blocked or a valve is not fully opened. Any deviation from your set load levels is detected immediately across the entire speed range, without the need for external sensors.
