PROJECT/REQUIREMENTS

Ludwig Perlinger GmbH has the following requirements for the compressed air supply for calfskin production: A reliable supply of dry, clean compressed air in accordance with DIN ISO 8573-1, class 1:4:2 is required. The compressed air generation must be energy-efficient and fulfil the BAFA subsidy criteria.

The implementation of a heat recovery system for heating and process water is also planned. The control of the compressed air station ensures optimum efficiency and capacity utilisation. In addition, the existing compressor must be integrated into the new station in order to increase efficiency.

SOLUTION

Two RSF-PRO 2-15.0 D compressors with frequency control were used for the compressed air supply. The existing RENNER compressor was switched on weekly via a timer to prevent downtime damage and act as a backup in the event of a pressure drop.

The pressure in the compressed air generation system was minimised in order to reduce energy costs. The compressors were utilised evenly and maintenance work was carried out without interrupting production.

The implementation of a heat recovery system led to an energy recovery of 70 %. In addition, an electric ball valve was used to keep the compressed air system pressurised during downtimes, which ensured compressed air quality, minimised cycles and increased the service life of the equipment.

IMPROVEMENT

New compressed air-approved pipework adapted to the volume flow was installed to minimise leakage and friction losses. The state subsidy from BAFA was approved, providing valuable support for the project. Thanks to heat recovery and room ventilation, the temperature in the compressor room remained in the optimum range even on hot summer days.
