Choosing the right compressor is critical to improving energy efficiency and ensuring uninterrupted production processes in industrial facilities. Each facility has unique requirements, so several factors must be considered when selecting a compressor. In this article, we will discuss the key criteria for choosing the right compressor for your facility.

1. Accurately Identifying Needs

The first step in selecting a compressor is to analyze the facility's compressed air requirements. Different industrial applications have varying air pressure, flow rate, and air quality needs. For example, the needs of an automotive factory may differ significantly from those of a food processing plant. Factors such as the pressure and duration of air usage are crucial in making the right choice. Therefore, it is essential to fully understand the intended application.

2. Deciding on the Compressor Type

Compressors are generally divided into two main categories: positive displacement and dynamic compressors. The type to choose depends on the specific needs of the facility.

Screw Compressors (Positive Displacement): Screw compressors are among the most widely used in the industry. They compress air using rotors, offering high efficiency and quiet operation, making them ideal for facilities with a continuous need for compressed air.
Piston Compressors (Positive Displacement): Piston compressors use a piston-cylinder mechanism to compress air to high pressures. They are often preferred for smaller capacities. While the initial investment may be lower, maintenance requirements are higher.
Scroll Compressors (Positive Displacement): Scroll compressors use a fixed and a moving spiral rotor to compress air. This design provides quiet operation with minimal vibration. With fewer moving parts, they require less maintenance and offer long-term reliable performance.
Turbo Compressors (Dynamic): Turbo compressors, a type of dynamic compressor, use a high-speed impeller to compress air. The kinetic energy generated by the rotating impeller is converted into potential energy as the air passes through a diffuser, increasing system pressure. They are suitable for large facilities and high-flow applications, delivering excellent performance but with higher initial costs.

3. Energy Efficiency

Compressors account for a significant portion of a facility's total energy costs. In today's environment of rising energy costs and increasing emphasis on efficiency, choosing energy-efficient compressors provides substantial long-term savings. Additionally, compressors with waste heat recovery capabilities can reduce the facility's energy requirements, offering economic advantages.

It is important to note that compressors alone can account for approximately 15% of the energy consumption in industrial facilities.

4. Quiet Operation

The noise level of compressors is important for worker health and a comfortable work environment. High-noise compressors may require additional investments if they fail to meet occupational safety standards. Models with quiet operation features improve the comfort of the working environment within the facility.

5. Ease of Maintenance

Regular maintenance of compressors is essential for longevity and efficiency. Models with low maintenance requirements and extensive service networks reduce operating costs. Additionally, shorter maintenance periods help minimize production downtime.

6. Spare Parts and Warranty

Another important factor to consider when choosing a compressor is the availability of spare parts and warranty coverage. Easy access to spare parts ensures uninterrupted use, and comprehensive warranties provide security against potential malfunctions.

Key Features

Smartpower IPM Motor Technology:

The Inversys Plus^pm series incorporates Permanent Magnet (IPM) motor technology, developed through Dalgakıran’s engineering expertise. These motors, classified as IE5 ultra-premium energy efficiency, deliver maximum energy efficiency even at low speeds. The F insulation class ensures high-temperature resistance, offering reliable performance even under harsh working conditions.

Compared to asynchronous motors, IPM motors are more compact and quieter, enhancing operational efficiency and providing a comfortable working environment.
Integrated with the screw, the motor reduces maintenance needs and losses, delivering higher efficiency and a longer lifespan.

Smartrotor Custom Rotor Design:

Specially designed rotor profiles for each model maximize performance.
Full integration with the motor eliminates the need for power transmission components, eliminating mechanical losses and optimizing efficiency.
Low rotor speeds ensure durability and quiet operation.

Compact Design and Small Footprint:

With its compact design and small footprint, the Inversys Pluspm series can be easily installed and operated even in confined spaces. This is a significant advantage, especially for production facilities with space constraints. (Compared to similar products on the market, the Inversys Plus^pm series occupies 45% less floor space.)

SmartDrive IPM Motor Driver (VSD):

The Variable Speed Drive (VSD) feature optimizes energy use.

By producing air only as needed and preventing sudden starts and stops, it enables up to 55% energy savings.
Advanced algorithms and enhanced PID control improve torque efficiency and extend motor life.

Smartronic Pro Controller:

Built-in Modbus communication supports data transfer to Scada and DCS systems, enabling remote system control.
With customized software developed by Dalgakıran, the Master/Slave equal aging function ensures synchronized maintenance intervals for all machines.
The high-capacity processor supports multiple language options and configuration flexibility.
Its 7” touch-sensitive display provides a user-friendly interface.

Heat Recovery Option:

The heat recovery option repurposes waste heat to heat water within the facility, reducing energy costs and contributing to environmental sustainability.

Tank-Mounted and Integrated Dryer Models:

The built-in water separator removes moisture formed during compression from the system.
The integrated dryer enhances air quality by removing moisture from the system, achieving a +3°C dew point and minimizing issues in the compressed air line.
With tank-mounted and dryer options, users can easily access dry air with plug-and-play convenience.

Low Noise Levels:

The Inversys Pluspm series operates quietly, thanks to advanced sound insulation, low rotor speeds, and variable-speed cooling fans.

Operation in Temperatures up to 45°C:

The revamped design ensures excellent performance even in challenging environments. The series operates seamlessly in ambient temperatures up to 45°C, maintaining productivity and reliability even in hot conditions.

VSD Fan for Energy Savings and Efficiency:

The Variable Speed Drive (VSD) fan minimizes energy waste by adjusting its speed based on compressor workload, running only when necessary. This reduces energy consumption and enhances overall efficiency.
