Built-in inverter

Speed control via inverter (VSD – Variable Speed Drive) enables precise control of motor speed and significantly reduces inrush current. As a result, the compressor starts smoothly, without sudden power surges, increasing the lifespan of components and overall system stability.

Key benefits of using an inverter in B&D screw compressors:

✅ Significant energy savings: Variable speed drive adjusts the compressor’s output to real-time air demand. This reduces energy loss during low demand and offers savings of up to 35% compared to fixed-speed compressors.

✅ Synergy with PM motor: When paired with the high-efficiency PM IE4 motor (with permanent magnets), energy savings can reach up to 42%. One of the most economical and eco-friendly solutions in the compressed air industry.

✅ Stable operating pressure: The inverter eliminates pressure fluctuations, keeping it within a narrow tolerance. This ensures stable operation of air-powered devices and reduces risk of downtime from pressure drops.

✅ Lower service costs: Smooth starts and stops reduce mechanical wear on the drive and compression system. Fewer on/off cycles also mean longer lifespan of bearings, couplings, and the motor.

✅ Lower noise and vibration: The inverter and PM motor combination significantly reduces noise and vibration. The compressor runs quieter, which is particularly valuable in production halls with many operating machines.

✅ Lower power grid load: Reduced inrush current minimizes negative impact on the electrical network – crucial for plants with complex electrical infrastructure.

The inverter in B&D compressors is not just an accessory — it’s the foundation of economical and stable operation, and when combined with the PM IE4 motor, delivers top-tier energy efficiency.

Control panel

The B&D controller is an advanced screw compressor management system that reacts in real time to key parameters and protects the unit from unplanned downtime. It works directly with the inverter and sensor set (temperature, pressure, flow), ensuring optimal operation and full system safety.

The clear display provides detailed information on:

✅ current alarms,

✅ temperature,

total operating hours,

screw module temperature,

current working parameters (pressure, load, speed).

The controller allows you to set minimum and maximum pressure values, configure working schedules, and manage load. With the built-in communication module, remote compressor monitoring and control via Wi-Fi is also possible, giving instant access to service data and performance metrics from anywhere.

B&D Cloud

B&D Cloud is a modern platform for remote monitoring and management of DHF series screw compressors, available exclusively via a dedicated mobile app. It enables real-time monitoring of operating parameters, usage history analysis, and energy report generation.

Benefits of using B&D Cloud:

✅ Full control via mobile app – monitor your compressor anytime, anywhere.

✅ Access to key parameters – pressure, temperature, energy use, and runtime.

✅ Real-time alerts – instant notification of faults, alarms, or exceeded thresholds.

✅ Service planning – service reminders and fault prediction to minimize downtime.

✅ Cost optimization – energy usage analysis and reports to boost efficiency.
