Product news

The robust and maintenance-friendly screw compressors of the RS-PRO series in the 30.0 kW to 55.0 kW power range with direct drive are now also available with integrated frequency converter. Furthermore, these screw compressors are now available with the new RENNERtronic Touch or RENNERtronic Plus Touch control systems.

In addition to belt-driven compressors in the 30.0 kW to 55.0 kW performance range, RENNER's product portfolio in the screw compressor sector offers a direct drive as an alternative, which guarantees reliable and powerful operation of the compressor. The power transmission of the direct-driven compressors is better than that of the belt-driven variant.

The RS-PRO D series with direct drive now has a version with integrated frequency converter. The RSF-PRO D variant, now new with RENNERtronic Touch as standard or optionally available with RENNERtronic Plus Touch control, offers intelligent frequency control, whereby the maximum possible air delivery quantity is automatically adapted to the set pressure range. If the pressure drops due to a peak in consumption, the REflex function releases the required reserves and ensures a constant working pressure. The REflex function can be variably adjusted from 6 to 15 bar without making any changes. Furthermore, the integrated function offers the user security of supply combined with energy efficiency.

In addition to an intuitive, smartphone-like 4.3 or 7" touchscreen, the new controls offer further advantages. For example, the software of the RENNERtronic Plus Touch control system is equipped with a comprehensive base load change over control (BLCO). Up to eight additional compressors can be controlled with this. RENNER compressors meet the requirements of the Industry 4.0 standard.

Further advantages of the RSF-PRO series: Integrated, highly efficient and speed-controlled radial fan with high residual pressure and low noise. Due to the partial load operation of the centrifugal fan, the RSF-PRO series offers a high energy saving potential.

Due to removable doors and struts the RS-PRO compressors allow easy access to maintenance components. The small footprint simplifies installation and supports flexible installation. The optionally available magnetic, easily replaceable front filter grid offers durst reduction. For heat recovery, RENNER offers a heat exchanger system for service or heating water.
