Compressed Air Dryers for Engineering Locomotive-- HCRP-900 Series

Modular structure, novel appearance, high reliability, wide applicability, outstanding performance with mobiles The use of anti-corrosive metal materials and rigid structure design make it strong enough to withstand various external vibrations, impact loads and other extreme conditions.With modular structure design, it can be assembled in “multi-chamber” ways according to the requirements. It can satisfy all the different capacity requirements of compressors on light rail, passenger & freight trains and heavy engineering locomotives.With standardized management, design and production, the products completely meet all the rail transit related national and international standards. It has passed a comprehensive test and has a long-term maintenance period.The pipeline structure is compact and there is no need to equip by-pass lines. The pipes and joints adopted are all with high quality which meets the standard of railway industry. Under the condition of power failure, the air can still be delivered downstream without manual control of other by-pass valves thanks to the special airway design. It also improves the security of locomotive wind system, and satisfies the high running security requirements of the wind system and locomotive.The system is equipped with water separator (liquid water separation efficiency: 99%) and high efficiency filters (accuracy: 0.01 micron, oil content: 0.01 ppm) to remove impurities such as liquid water, oil mist and solid particles.Full functional electronic control system:a. Electronic control system is full automation controlled with good safety and reliability.b. The electronic control system’s power supply is DC 24V which is stable and reliable.c. The modular curing packaging meets the requirements of strong vibration, and the overall protection level is IP68.d. The system has passed the electromagnetic compatibility test of the national railways product quality supervision and inspection center.e. The system has anti-freeze heating, control and output functions.For more information, please login http://www.heca.net.cn/.
