8-20HP XTLD medium 4-cylinder semi-hermetic compressor series is specially optimized and upgraded for humid and high-temperature tropical markets such as Southeast Asia, South America and coastal Africa, relying on British Xiteliduo advanced refrigeration technology and targeted market customization design. Aiming at the common failure problems of ordinary compressors such as easy rust, component aging, circuit damp failure and reduced cooling capacity in high-temperature, high-humidity and rainy tropical environments, this series of products adopt overall anti-corrosion spraying treatment, internal core component anti-rust and moisture-proof optimization, and enhanced sealing protection design, effectively improving the equipment's environmental adaptability in humid tropical climates. The 4-cylinder round machine structure has stable compression performance and strong environmental resistance, covering 8HP to 20HP full power gradient, fully meeting the refrigeration demands of small, medium and large commercial and industrial cold storage in tropical markets. All products pass strict humid environment simulation test and high-pressure sealing test, with stable refrigeration performance, low vibration and low noise in long-term humid operation. The whole series supports multiple mainstream refrigerants, with high energy efficiency and low failure rate, effectively reducing the maintenance cost of overseas users in humid environments. Targeted at the characteristics of frequent rain, high humidity and high temperature in tropical markets, this customized anti-corrosion compressor series solves the pain points of poor durability and unstable performance of ordinary equipment in local markets. It is widely applicable to tropical supermarket cold rooms, food processing cold storage, agricultural product cold chain and industrial supporting refrigeration projects, and is the most suitable stable refrigeration equipment for global humid tropical cold chain markets.
