PM IE4 motor - efficiency and reliability

Permanent Magnet (PM) motors are a key technological element in theDHF F18AIRseries screw compressors manufactured byB&D. PM engines are distinguished by exceptional efficiency and performance, which translates into excellent performance of these devices.

The basic features and benefits associated with the use of PM motors in these compressors are:

✅ High energy efficiency (IE4 class): The use of PM motors in the IE4 efficiency class means meeting one of the most restrictive international standards regarding energy consumption. In practice, this translates into lower electricity bills, reduced carbon footprint and more sustainable operation of compressed air installations.

✅ Precise regulation: PM engines enable precise adjustment of rotational speed and torque, which is extremely important in compressors to adjust performance to changing operating conditions. Thanks to this, B&D series compressors operate only when and as intensely as the production process requires.

✅ Noise and vibration reduction: PM motors are known for their low noise and vibration levels, which translates into user comfort and minimizes the impact on the work environment.

✅ Long-term durability: The absence of brushes in PM motors means they require less maintenance and are less prone to failure, which extends the life of the entire compressor system.

✅ High reliability: PM motors in the IE4 class are resistant to damage and operate stable even after long-term operation in demanding industrial conditions. This guarantees continuity of production and reduces the risk of downtime.

TheIE4class is not only a formal parameter - it means measurable energy savings, greater reliability and a step towards modern, energy-saving production.

Screw compressor with refrigerant dryer

In this model, the tank with an integrated refrigerant dryer plays a key role. The tank not only allows the storage of compressed air, but also helps stabilize the pressure in the installation, which translates into more uniform and reliable operation of machines connected to the network. Additionally, it reduces the frequency of compressor starts, which significantly extends its life and improves the energy efficiency of the entire system. Thanks to this, the user receives a ready-to-use all-in-one' solutionthat combines a compressor, dryer and tank.

A refrigeration dryer is an advanced devicedesigned for effective compressed air treatment. Thanks to its compact design and the use of the ecological R134a refrigerant, the dehumidifier ensures high quality of exhaust air, meeting the ISO 8573-1 standard in class 1.4.1.

Key features of a refrigerated dryer:

✅Integrated filtration system – the dehumidifier is equipped with a fine filter with a gradation of 1 µm and a final filter of 0.01 µm, which guarantees effective removal of contaminants and oil from the air.

✅Control panel – a modern control panel allows you to monitor the operation of the device, informing about any irregularities, such as low or high temperature and high pressure alarms.

✅Automatic condensate ejector – ensures maintenance-free condensate removal, which increases the efficiency and reliability of the system.

Control panel

The B&D controller is an advanced screw compressor management system that responds in real time to key parameters and protects the device against unplanned downtime. It cooperates directly with the inverter and a set of sensors (including temperature, pressure and flow), which ensures optimal operating conditions and full installation safety.

The clear display provides detailed information regardinging:

✅current alarms

✅ temperature

✅ number of hours worked,

✅ screw module temperature

✅ current operating parameters (pressure, load, speed).

The controller allows you to change the minimum and maximum pressure values, configure work schedules and load control. Thanks to the built-in communication module, it is also possible to remotely monitor and manage the compressor via Wi-Fi, which gives quick access to service data and operating parameters from anywhere.

B&D Cloud

B&D Cloud is a modern platform for remote monitoring and management of DHF series screw compressors, available only through a dedicated mobile application. It allows you to view operating parameters in real time, analyze the history of device operation and generate energy reports.

Benefits of using B&D Cloud:

✅ Full control in the mobile application - monitoring the compressor from anywhere and at any time.

✅ Preview of key parameters - pressure, temperature, energy consumption and number of hours worked.

✅ Real-time notifications – immediate information about faults, alarms or exceeded limit values.

✅ Service planning – inspection reminders and fault prediction to minimize the risk of downtime.

✅ Cost optimization - energy consumption analysis and reports to increase the efficiency of the installation.
