• Quiet and Stable : Operating at 1400 RPM, the compressor operates at lower speeds than traditional models, reducing noise and vibrations.

Usage Procedure

1. Installation : Place the compressor on a flat and stable surface. Make sure there is adequate ventilation around the machine for cooling.
2. Electrical Connection : Connect the compressor to the three-phase electrical network, following the manufacturer's specifications. Verify that connections are secure and comply with safety standards.
3. Switching on : Start the compressor via the control panel. The inverter will automatically adjust the motor speed according to the compressed air needs.
4. Adjustment and Monitoring : Use the control panel to monitor and adjust pressure and flow settings. The inverter will optimize the motor speed to reduce energy consumption.

Matching accessories

• Filters and Separators : Essential for keeping compressed air clean and free of contaminating particles.
• Storage Tanks : Used to increase the storage capacity of compressed air and stabilize the flow.
• Air Dryers : To remove moisture from compressed air, improving quality and preventing corrosion.

Mathematical Formulas for Optimal Use

• Compression Capacity:

  $$Q$$

  Where QQ $Q$ is the compression capacity, VV $V$ is the air volume, P1P1 $P$ $1$ is the inlet pressure, P2P2 $P$ $2$ is the outlet pressure, RR $R$ is the gas constant and TT $T$ is the temperature.

• Energy Consumption:

  $$E$$

  Where EE $E$ is the energy consumed, PP $P$ is the engine power, tt $t$ is the operating time and efficiency is the compressor performance.

Workable Materials

The 37 kW rotary screw compressor is designed to handle compressed air. It is not intended to work with solid or liquid materials, but is ideal for applications requiring a constant and adjustable flow of compressed air.

Maintenance

• Oil Check : Check and replace oil regularly to ensure adequate lubrication and prevent component damage.
• Cleaning Filters : Filters must be cleaned or replaced periodically to maintain the quality of the compressed air.
• Cooling System Inspection : Check the fan and cooling system to avoid overheating and ensure optimal operation.
• Periodic Check : Check the electrical connections and control panel to ensure that the compressor is working properly.

Evaluation of Good Used

• Visual Condition : Examine the compressor for any signs of wear, damage or corrosion. A used compressor in good cosmetic condition is likely to have been well maintained.
• Operating Hours : Check the hours of use to evaluate the level of wear. Fewer hours is indicative of limited use and therefore less wear.
• Maintenance Documentation : Request maintenance documentation to confirm that the compressor has undergone regular checks and repairs when necessary.

Sectors of Use

• General Industry : Ideal for industrial environments requiring a continuous and reliable flow of compressed air.
• Workshops and Laboratories : Perfect for small and medium work environments that need a silent and efficient compressor.
• Automation and Metalworking : Used in applications requiring precise regulation of air pressure.

Advantages of Buying Used

• Reduced Cost : Buying a used compressor allows you to get a high-quality unit at a lower price than new.
• Immediate Availability : A used compressor is often available for purchase and installation without long waiting times.
• Reliability and Performance : A well-maintained used compressor can offer performance comparable to that of a new compressor, with the advantage of a lower initial price.

Conclusion

The 37 kW (50 HP) Used Rotary Screw Compressor with Inverter represents an excellent choice for those looking for reliable and versatile equipment at a low cost. Thanks to its direct drive, low rpm and advanced technology, it offers high energy efficiency and durability, making it ideal for a wide range of industrial and artisanal applications.
