STSD Series Fixed Speed Rotary Screw Compressors \u2013 Premium Design for Reliable Industrial Operation<\/h3>\n

The STSD series combines robust engineering with advanced energy efficiency to deliver stable compressed air production for critical industrial processes.<\/p>\n

Its direct-drive architecture eliminates mechanical losses associated with belt or gear transmission systems, improving overall system efficiency. The use of IE3 motors with Class F insulation enables reliable operation under demanding conditions.<\/p>\n

Each unit is designed to simplify maintenance tasks, reducing service time and long-term operating costs. The digital control system allows monitoring of key parameters such as pressure, temperature, and service hours.<\/p>\n

The series is certified under performance standards ISO 1217:2009 Annex C, ensuring airflow and power measurements comply with international testing protocols.<\/p>\n<\/div>\n

The STSD series uses heat exchangers from AKG – Thermal Systems with bar-and-plate design, up to 60% more compact than traditional fin-and-tube systems, improving thermal dissipation and reducing particle accumulation.<\/p>\n

The motors supplied by WEG S.A. are non-proprietary, making replacement easier and reducing service costs. Models up to 40 HP use tri-voltage motors, while higher capacities operate in standard 460V configuration.<\/p>\n

The microprocessor-based control system includes:<\/p>\n
