Dräger Medical Compressed Air Supply System

Modern medicine requires a stable and reliable source of compressed air that meets high quality and safety standards. Dräger has been developing and manufacturing central compressed air systems for over 50 years, used in hospitals and private medical practices. Their compressor units guarantee uninterrupted medical air supply in compliance with the European Pharmacopoeia and ISO 7396-1, ensuring reliable operation of anesthetic, intensive care, and surgical equipment.

Types of Compressors Used for Compressed Air Supply:

• •Piston Compressors (DWSC Series)
• •Screw Compressors (DWLC Series)

Both types offer high performance, compact design, sound insulation, and integrated monitoring systems. They provide optimal energy efficiency, reliability, and cost-effectiveness and can be installed in multi-compressor systems to enhance redundancy and ensure continuous compressed air supply.

DWSC Series Piston Compressors

Piston compressors are a proven solution for medical facilities requiring high air pressure and reliability. They feature a two-stage compression system that enables an operating pressure of up to 15 bar.

Key Features of Piston Compressors:

• •Compact design with ultra-sound-absorbing casing for noise minimization.
• •Integrated electronic control unit with sensor-based monitoring.
• •Two-stage compression system with air cooling.
• •Vibration-isolated mounting to minimize mechanical stress and vibration.
• •Automatic start and load control for optimal energy usage.
• •Overload protection and compressor block temperature monitoring.
• •Network contactor or star-delta starter (from 5.5 kW).
• •Integrated filtration block to ensure high air quality.

These compressors are ideal for systems with three or four compressors, ensuring high reliability of air supply.

DWLC and DWLS Series Screw Compressors

Screw compressors are a modern solution for medical facilities requiring high performance, continuous operation, and energy efficiency. They feature a single-stage compression system with oil injection, allowing pressures of up to 13 bar.

Key Features of Screw Compressors:

• •Continuous operation due to optimized screw block design.
• •Compact, soundproof housing ensuring low noise levels.
• •Built-in automatic control system for optimal performance.
• •Steel air and oil pipelines with high-quality hydraulic connections.
• •Thermostatic oil control system maintaining optimal temperature.
• •Flexible mounting system for quick installation and alignment.
• •Automatic monitoring of operating parameters, including pressure, temperature, and airflow.

These compressors are frequently used in centralized compressed air systems in hospitals requiring high reliability and efficiency.

Advantages of Dräger Multi-Compressor Systems

Dräger's central compressed air systems utilize three or four compressors with load distribution between them. Compared to systems where each compressor must cover 100% of the hospital’s demand, using four compressors allows load sharing between two units, reducing equipment wear and energy consumption.

Key Benefits:

• •Continuous air supply – maintenance can be performed without system shutdown.
• •Cost-effectiveness – reduced load extends compressor service life.
• •Flexibility – systems can be adapted to specific hospital requirements.
• •Intelligent control – automatic compressor operation adjustment for optimal performance.

Air Preparation System: Filtration and Drying

To ensure high-quality medical air, Dräger systems utilize:

• •Multi-stage filtration system removing dust, bacteria, and aerosols.
• •Adsorption dryers lowering dew point to -46°C, preventing condensate formation.
• •CO monitoring system (Medical Air Guard CO) for contamination control.

Receivers and Pressure Reduction Stations

The receiver size is selected based on compressor capacity and required flow stability.

Pressure reduction stations maintain stable system pressure, which is critical for respiratory devices and surgical instruments.

Dräger piston and screw compressors are high-tech, reliable, and energy-efficient solutions for medical institutions, ensuring a stable compressed air supply in compliance with the strictest international standards. With innovative control systems, high-quality filtration, and optimal energy characteristics, these compressors guarantee uninterrupted medical equipment operation and patient safety.
