Product catalog summary

Overview: This document details the industrial compressors by BAUER KOMPRESSOREN GmbH, covering specifications, configurations, and options for air-cooled and water-cooled models designed for industrial use.

Air-Cooled Industrial Compressors: The K 22 – K 28 range compresses air, nitrogen, helium, and argon, available in open and Super Silent versions for noise-sensitive environments. They handle intake pressures from atmospheric to 100 mbarg and output pressures from 30 to 500 bar.

Water-Cooled Industrial Compressors: The BK 23 – BK 52 range is for high-reliability applications like continuous oil and gas compression, featuring single-acting plunger pistons and twin ferrule fittings. They manage intake pressures up to 16 barg and output pressures from 25 to 420 bar.

Key Features and Options: Configurations include air-cooled horizontal and water-cooled setups. Options include Super Silent design, cutting ring fittings, and various compressor oils. Voltage and frequency options are available, with energy efficiency classified as IE3.

Automation and Control: Control systems like B-CONTROL MICRO and B-CONTROL II offer basic to premium automation features, including interconnected operation for lead and lag configurations.

Technical Annex: Additional technical details cover operating conditions, flow rate measurements, correction factors, and pressure unit conversions, along with environmental factors like temperature development and acoustic noise levels.

Conclusion: BAUER KOMPRESSOREN's compressors are versatile and robust, designed to meet diverse industrial needs with customizable options for enhanced performance and efficiency.

Offshore Specifications: Components are painted with offshore quality paint per BAUER's BS Coat 5001 standard to withstand aggressive environments, categorized by corrosivity according to DIN EN ISO 12944-2.

Compressor Oils: Fully synthetic oils are recommended for optimal performance, with high-quality oils specified in the operating instructions to maintain warranty validity.

Voltage and Frequency: Standard voltage is 400 V ± 10%, with other voltages available. The standard frequency is 50 Hz ± 2%, with 60 Hz as an option.

Energy Efficiency: The standard energy efficiency class is IE3, aligning with EU regulations to reduce energy consumption and CO2 emissions.

Explosion Protection: Compressors in explosive environments must comply with ATEX directives, with explosion-proof components available for safe areas.

Safety Valves: Equipped with TÜV-certified safety valves, pre-adjusted and sealed at the factory for simplified on-site commissioning.

Compressor Control: B-CONTROL MICRO and B-CONTROL II units offer features like automatic monitoring, language selection, maintenance management, and remote control capabilities.

Startup Configuration: Options include star-delta starting, soft start, and speed control via frequency converter, with recommendations based on motor output.

Interconnected Operation: Compressors can operate in interconnected systems for pressure-dependent base and peak load operation or stand-by duty.

Electronic Monitoring: Includes shut-down pressure, oil pressure, intermediate pressures and temperatures, intake filter, intake pressure, oil level, final stage temperature, and cooling air temperature monitoring.

Automatic Condensate Drain Device: Equipped with automatic drainage during operation and depressurization at shutdown.

Pre-Lubrication Pump: Required for compressors idle for 2 weeks or more to ensure oil lubrication before start-up.

Analogue Pressure Gauge: Mandatory in some countries, with a 63 mm diameter and glycerine-filled for dampening.

Inclined Position: Standard max. inclined position is 10 degrees, with options for up to 30 degrees for specific applications.

Temperature Specifications: Intake temperatures range from -10 to +45 °C for air-cooled and -10 to +55 °C for water-cooled compressors. Ambient temperatures are designed for +5 to +45 °C.

External Installation: Recommended to use containers or concrete housing for protection against environmental influences.

Intake Buffer Vessel: Acts as a pulsation damper during gas compression, reducing oil consumption and noise.

Condensate Collecting Tank: Collects condensate and prevents gas losses, with optical filling level indication and automatic shutdown at max level.

Coalescence Filter: Removes particles and separates aerosols, with options for connection to automatic condensate drain.

Testing of Pressure Vessels: Complies with EC Directive DGRL97/23/EG, with calculations according to Technical Rules AD2000.

Pressure Equipment Directive (PED) Compliance: Approved to manufacture pressure equipment up to category 4 according to PED DGRL97/23/EG.

Spare Parts and Documentation: Spare parts list is part of the standard operating instructions, available in multiple languages. The EC Declaration of Conformity confirms compliance with essential health and safety requirements.

Final Check and Acceptance: Each compressor undergoes a final check including functional and leakage testing, electrical checks, and performance data inspection.

Protective Storage and Packing: Compressors are packed for standard shipping, with additional protective measures for sea freight. Maximum storage period in unopened packing is 24 months.

Operating Conditions: Volume flow rate and power consumption depend on conditions such as intake temperature and coolant medium temperature.

Compressor and Booster Systems: Compressors and boosters have multiple stages for compressing air or gas, with boosters using existing primary pressure to save energy.

Flow Rate and Power Consumption: Free Air Delivery (F.A.D.) is measured at the compressor outlet, with correction factors for deviations in medium, altitude, intake temperature, and cooling medium temperature.

Operating Modes: Compressors can operate continuously or in cycle operation, with speed control to match compressed air use.

Temperature Development and Gas Data: Temperature development is monitored to ensure stable operating conditions, with data for various gases provided.

Pressure Unit Conversion and Moisture Content: Conversion charts for pressure units and moisture content data based on temperature are included.

Dewpoint and Pressure Dewpoint: Dewpoint is the temperature at which air or gas becomes saturated with moisture. Pressure dewpoint is specific to compressed air or gas and depends on compression pressure.

Humidity of Air: Provides a table of maximum possible humidity levels at various temperatures and atmospheric pressure.

Acoustic Noise: Sound pressure level decreases by 6 dB with each doubling of distance from the source, measured according to ISO 3744.

Protection Classes: Electrical equipment protection is classified under DIN EN 60529, with specific IP ratings for dust and water ingress protection.

Dimensioning of Pressure Vessels: Properly dimensioned storage vessels reduce pressure fluctuations and minimize compressor cycles, with a formula provided for calculating storage volume.
