15-30HP XTLD large 4-cylinder compressor series is a high-quality industrial heavy-duty compressor cluster fully certified by 100% pressure leakage test, authorized by British Xiteliduo refrigeration technology, focusing on high-standard industrial refrigeration scenarios requiring high sealing performance and zero leakage. Different from ordinary compressors that only conduct simple sampling inspection, all XTLD large-power compressors undergo full-product 100% high-pressure air tightness test, full-cycle pressure holding leakage detection and sealing performance calibration before delivery, thoroughly eliminating hidden dangers of refrigerant leakage and pressure instability, ensuring 100% sealing qualification rate of finished products. The series covers 15HP, 20HP, 25HP and 30HP full large-power gradient, matching displacement from 73.6m³/h to 84.5m³/h, fully meeting the refrigeration demands of medium and super-large industrial cold storage. The whole series adopts standardized industrial-grade structure design, with stable compression performance, low vibration and low noise, adapting to 24-hour long-term high-load continuous operation. With multi-refrigerant compatibility and wide temperature range working condition adaptation, it can freely switch between medium-temperature fresh preservation and low-temperature freezing. Relying on strict full inspection quality control system and British technical standards, this series of compressors has outstanding advantages in sealing stability and operational reliability, effectively solving the common leakage problems of traditional industrial compressors. It is widely used in high-standard industrial refrigeration projects, food safety cold chain, pharmaceutical storage and export-grade cold storage engineering, and is a high-qualified certified refrigeration equipment trusted by global engineering purchasers.
