Machine Utilization & Process Flow

The CompAir L45RS rotary screw compressor stands as the primary mechanical engine and core driver of the entire system. Ambient air is pulled through intake pre-filtration panels (visible in BONPERTUISA1_14 (3).jpg and BONPERTUISA1_14 (6).jpg) and compressed by the $45 \text{ kW}$ oil-injected screw element. The integrated frequency inverter continuously modulates the motor speed up to $4,250 \text{ R.P.M.}$ to precisely align air volume output ($8.02 \text{ m}^3\text{/min}$ max) with factory demand, avoiding wasteful start-stop cycles.

Hot, saturated air leaving the compressor block transitions into the CompAir F95HS refrigeration dryer. Utilizing an eco-friendly R407C refrigeration loop, the dryer chills the compressed air down to its pressure dew point, forcing water vapor to condense and separate from the stream. This preserves downstream pipe networks and pneumatic tools from internal rust and moisture carryover.

The dried, purified air is finally directed into the 986-Liter vertical Cordivari tank. Acting as a critical structural buffer, the receiver minimizes system pressure spikes, prevents excessive short-cycling of the compressor screw during brief peaks, and maintains a stable repository of compressed energy ready for plant automation.

System Highlights

• High-Efficiency Variable Matching: By matching actual usage via real-time motor regulation, the L45RS compressor operates as a modern demand-responsive utility machine rather than a fixed-speed overhead drain.
• Intelligent Monitoring Backbone: The premium DELCOS XL graphic display simplifies preventative maintenance schedules by reporting running metrics, trip warnings, and automated emergency stops right from a central diagnostic point.
• Industrial Safety Footprint: Built fully compliant with CE directives, including high-pressure threshold margins ($15.83 \text{ bar}$ vessel test rating) and thermal protections within the air-drying circuit.
