STSP Series Fixed Speed Rotary Screw Compressors \u2013 Industrial Power with Maximum Reliability<\/h3>\n

The STSP Series by South-Tek is designed for companies that require consistent compressed air production with pressure stability and high energy efficiency. Its direct-drive system eliminates mechanical losses, optimizes power transmission, and extends equipment service life.<\/p>\n

It incorporates high-performance components such as a Termomeccanica airend, IE3\/IE4 motors with Class F insulation and IP55 protection rating, a two-stage air\/oil separator, and an intelligent cooling system with a thermostatic valve.<\/p>\n

Each unit undergoes rigorous testing under demanding conditions to ensure thermal stability, low vibration levels, and reliable 24\/7 performance.<\/p>\n<\/div>\n

The STSP Series integrates a single-stage, oil-lubricated airend with an air\/oil aftercooler. The separation system reduces oil carryover to levels of 2\u20133 PPM, ensuring air quality and system protection.<\/p>\n

The microprocessor-based control panel allows monitoring of pressure, temperature, operating hours, and preventive maintenance schedules. It can also be integrated into remote monitoring and centralized management systems.<\/p>\n

Models rated at 75 kW and above incorporate a radial fan for superior cooling, noise reduction, and improved thermal efficiency. The system includes:<\/p>\n
