PNEUMATICS 22 HYDRAULICS & PNEUMATICS July/August 2025 www.hpmag.co.uk Rotary lobe blower delivers energy efficiency and smart control TYR PLUS rotary lobe blower with integrated variable speed drive (VSD) is the new, energy-efficient solution from the established TYR product range. This compact blower with a footprint of < 3 m2 offers flexible monitoring and controlling capabilities. The TYR PLUS is currently available for volume flows in the range of 900 to 4.000 m3/h. The four models in the PLUS series have a maximal relative differential pressure of between -500 and +800 hPa (mbar) and are available in either an overpressure or vacuum version. Many applications have operational peaks and troughs, where demand for overpressure or vacuum fluctuates dramatically. There can be as much as a 50% difference in power consumption between standard operation and periods of high demand. A VSD allows the blower to rapidly adjust its rotational speed accordingly. Compared to a traditional blower, which always runs at a constant speed, the TYR PLUS has high energy savings potential and can reduce operating costs. The TYR PLUS also comes with a range of integrated software features. Remote condition monitoring allows both for flexibility and an early warning about potential equipment problems. By continuously observing and recording parameters, software can build up a picture of normal running conditions. It then uses this data, such as power consumption, temperature, and inlet and outlet pressure, to alert the operator when a value exceeds its typical range. The monitoring and control features are accessible through a user-friendly color touch display located at a convenient height of 1.5 m.

Though a full digital control system redesign might be prohibitive, integrating digital positioners and process controllers can offer many of the same benefits without requiring a complete overhaul. To achieve this transition, Bürkert’s SideCONTROL series offers a seamless retrofit solution for existing pneumatic control valves. Upgrading pneumatic control valves to digital communication and control can optimise precision and repeatability, as well as opening access to real-time process data. While redesigning to a full digital control system could be advantageous, the initial time and cost requirements might be prohibitive. As an alternative, integrating digital positioners and process controllers for pneumatic control valves can fulfil many of the advantages without committing to a complete digital transition. This approach is ideal to modernise existing systems as well as improve new designs involving pneumatic control valves. To offer a seamless transition, Bürkert has introduced the SideCONTROL series of electropneumatic positioners and controllers. The range achieves universal mounting to virtually any existing pneumatic control valve actuator, including part-turn and linear actuators that comply with NAMUR standards. An interface for non-standard actuators is also available, including a special adapter kit for Type 3277 Samson actuators, enabling a digital upgrade for valve strokes from 7.5 mm to 30 mm. The simplest approach to digital retrofit is via IO-Link connectivity, a standardised protocol for connecting sensors and actuators with automation systems. Unlike analogue communications, IO-Link enables bidirectional data exchange. The advantages of two-way, high-speed
