Atlas Copco Compressor Cooler GA250

1. Product Overview

The Atlas Copco GA250 series compressor stands as a benchmark in industrial compressed air system setups, with its cooler module being the core module ensuring efficient operation. This cooler features thermodynamic optimization design, utilizing forced convection heat transfer principles to effectively dissipate compression heat. It's suitable for working conditions ranging from 7.5bar to 13bar pressure with flow rates up to 43.7m³/min.

The product adopts modular integrated design, seamlessly compatible with dual-host parallel system setups, and finds extensive use case in industries with stringent compressed air quality requirements such as petrochemicals, automotive manufacturing, and food processing.

From a technological evolution perspective, the GA250 cooler inherits Atlas Copco's technical heritage dating back to 1957 when the U-series oil-free screw compressor was first introduced. Its core cooling tube bundle uses 316L stainless steel material, supply 300% better corrosion resistance than traditional carbon steel. Combined with the dual-process counterflow heat exchange structure, the heat exchange overall efficiency has enhanced by 45% compared to first-generation products. This design significantly extends equipment service life while dramatically reducing downtime risks caused by cooling failures.

2.2 Innovative Technological Breakthroughs

Intelligent Temperature Control system setup

The Elektronikon® MK5 controller dynamically adjusts cooling fan speed by monitoring cooling water temperature, flow rate, and compressor exhaust temperature in real-time. Under full load conditions, this system setup enhances cooling overall efficiency by 22% and saves 18% more energy compared to traditional fixed-speed fan solutions.

Anti-fouling Self-cleaning Technology

The cooling tube inner wall features a nano hydrophobic coating combined with an automatic backwash program, effectively inhibiting calcium carbonate deposits. Experimental data shows that with circulating water hardness at 300ppm, the heat exchange overall efficiency attenuation rate is only 3.2% after 2000 hours of continuous operation, far below the industry average of 15%.

Dual-medium Redundant Design

The module incorporates both air-cooled and water-cooled circuits. When the primary cooling system setup fails, the backup circuit can automatically switch within 15 seconds. This design increases the equipment's MTBF (Mean Time Between Failures) to 12,000 hours, 40% higher than single-medium system setups.

2.3 Energy overall efficiency Optimization Indicators

According to ISO 1217:2009 standard testing, the GA250 cooler achieves specific power consumption of 5.8kW/(m³/min) at 10bar pressure and 40°C surrounding temperature, 12% lower than comparable products. Its comprehensive energy overall efficiency index (IE) reaches 0.92, meeting EU ERP Directive Tier 2 energy efficiency standards.
