1. Product Overview: The Technological Foundation of Efficient Cooling system setups

The Sullair Compressor Cooler TRA400 is a heat exchange unit specifically built for industrial-grade centrifugal air compressors, belonging to the cooling system setup series compatible with Sullair's TRE/TRA line of centrifugal compressors. This product embodies three core values: "high-overall efficiency heat exchange, low energy consumption operation, and long-life design." Through fine-tuned fluid dynamics pathways and material use cases, it help s ensure stable operating temperatures for compressors under continuous high-load conditions, preventing operational performance degradation or downtime risks caused by overheating.

Technical Background & Market Positioning

As a global leader in centrifugal compressor technology since 1965, Sullair has continuously driven technological innovation, with its cooler products now in the third generation of high-overall efficiency heat exchange technology. The TRA400 cooler leverages the manufacturing system setup of IHI-Sullair's Suzhou plant, adopting the same heat exchange design standards as large centrifugal machines in the TA and NK series, while being modularly adapted for medium and small compressor markets (such as TRE40-TRE100 models). Compared to competitors, its core advantages include:

• 25% enhanced heat exchange overall efficiency: Patented straight-through tube structure increases contact area between cooling water and compressed air by 40%, significantly reducing outlet temperature fluctuations
• 30% minimized maintenance costs: Horizontal split-body design enables quick disassembly, cutting maintenance time to 1/3 of traditional coolers
• Enhanced environmental adaptability: Supports operation in wide temperature ranges from -10°C to 50°C, meeting extreme condition requirements in mining, marine, and other use cases

2. Technical Features & Data Specifications

Core Structure & Material Innovation

• Dual-channel heat exchange core: Utilizes titanium alloy impeller cascade structure with cooling water flowing through shell-side straight tubes and compressed air passing through water straight tubes, forming counterflow heat exchange paths. Test data shows this design minimizes exhaust temperature from 120°C to below 45°C in 45°C surrounding conditions, achieving 92% heat exchange overall efficiency.
• Anti-corrosion coating technology: Nano-ceramic coating on cooling tube interiors enhances corrosion resistance 5-fold, extending service life to 80,000 hours (continuous operation).
• Smart temperature control valve group: Integrates proportional control valves and pressure sensors to adjust cooling water flow in real-time based on exhaust temperature, preventing condensate corrosion from over-cooling.
