ELGi RECIPROCATING COMPRESSOR – ADVANCED OIL-LUBRICATED TECHNOLOGY FOR INDUSTRIAL COMPRESSED AIR

POWERING INDUSTRIES WITH RELIABLE COMPRESSED AIR

The ELGi reciprocating or piston compressor is engineered for robustness and reliability. The two-stage reciprocating air compressors are designed to meet the rigorous demands of various industries, providing a consistent compressed air supply. The LD Series reciprocating air compressors combine high-quality components with a low operational speed to deliver efficiency and low noise levels of 70-75 dB(A).

WHAT IS A RECIPROCATING AIR COMPRESSOR?

A reciprocating air compressor (or piston compressor) is a positive displacement machine that uses pistons driven by a crankshaft to compress air. In the ELGi LD Series, the air is compressed in two-stages for greater efficiency. The ELGi piston compressor “Direct Drive Advantage” means the motor directly drives the compressor element, resulting in fewer parts, greater efficiency, and reduced power loss.

UNDERSTANDING THE WORKING PRINCIPLE OF THE ELGi LD SERIES

Two-Stage Compression for Peak Efficiency

The ELGi LD Series employs a two-stage reciprocating- type air compressor principle, a design choice that significantly boosts efficiency and performance. In a single-stage unit, all the compression work is done in one step, leading to high internal temperatures. By contrast, the two-stage process splits the compression work, leading to cooler operation and greater volumetric efficiency.

1. Primary Compression: Atmospheric air is drawn into the larger-diameter cylinder and compressed to an intermediate pressure.

2. Intercooling: The air is then efficiently cooled by the large Aluminum intercooler. This cooling process is vital as it increases the air’s density, making the subsequent compression step more energy efficient. The LD Series benefits from larger aluminium inter & after coolers which provide 44% more heat transfer area.

3. Secondary Compression: The pre-cooled, denser air moves into the smaller-diameter cylinder, where it is compressed to the final working pressure of 12 bar (g).
