The Two-stage Advantage
ELGI two-stage tandem screw compressors are build to achieve high efficiency. Compression is divided equally between two stage to achieve optimum results. The first stage takes in air, compressors it to intermediate pressure and fees it to the second stage inlet. The second stage compresses the air further to the final discharge pressure. During this process most of the heat generated by compression in the first stage is removed by the lubricating oil and the remaining heat is lowered by splash of cool oil prior to the entry into the second stage.
Energy Costs account for 85% of the total cost of compressed air production. The ELGI Tandem air compressors save energy costs by 7-13% thereby ensuring fast payback periods.
Optional Logic Control
State-of-the-art microprocessor based control is available with industrial standard PLC coupled with a MIMIC panel to display all essential functions, build-in safety and inter-locks.
