Due to the very large number of samples per day, the Institute of Mining Comprehensive Utilization of the Chinese Academy of Geological Sciences has high requirements for the stability of water chillers assisting XRD and XRF analysis equipment. However, the RUISHENBAO CW series water chillers perfectly meet the requirements of their high precision control and long-term stable operation, so that the Institute decided to purchase two water chillers for their XRD and XRF equipment after comparison.

CW series’ high-precision circulating water chiller, developed by Ruishenbao Analytical (Shanghai) Co., Ltd., is an auxiliary cooling device for analysis equipment. It has the supreme temperature control accuracy up to ±0.1℃. What is more, the water chiller adopts high-end accessories for its water circulation system, refrigeration system, electrical control system, and high temperature alarm system. High-performance compressors are especially outstanding, which can guarantee the long-term stable operation of the host analysis equipment. Among all RUISHENBAO water chillers, the divided-structure water chiller has prominent features, for it is composed of two parts, the indoor and outdoor part. The room temperature is not affected during work, and at the same time the indoor noise is significantly reduces. Besides, the outdoor part is exclusively equipped with dust filters, which is conducive to cleaning dust and debris. Therefore, it can maintain long-term operation without any fault. 

Features:

• Ultra silent design, low impact on the work environment;
• Imported high-efficiency compressor to improve refrigeration efficiency;
• Excellent temperature control accuracy in this industry, up to ± 0.1 °C;
• High-precision controller to directly reflect the operation and failure of the equipment;
• Complete categories: Divided or integrated or air-cooling or water-cooling chillers for selection;
• Unique dust filter design to protect compressors without need to control the cleaning;
• The device has been tested in the factory simulated conditions of actual use,and only qualified ones can be sold.
• Ethylene glycol solution can be used as coolant. The outlet temperature of freezing water can be as low as 5 °C;
• The compressor automatically returns oil, and the installation surface of the outdoor machine of the divided chiller can be higher than that of the indoor machine;
• Imported high-efficiency vortex flexible compressor with low failure rate to ensure the equipment is stable and uninterrupted operation for a long time.

Introduction:

The Institute of Mining Comprehensive Utilization of the Chinese Academy of Geological Sciences(referred to as IMCU), founded in 1964, was formerly known as the Technical Processing Office of the Geological Mining Department of the Ministry of Geology. It is mainly engaged in the comprehensive evaluation and development of mineral resources. Three major centers have been built up with the most advanced instruments and equipment in China, including the Mining and Metallurgical Engineering Research Center, the Analysis and Testing Center, and the Resource and Environmental Geology Research Center. At present, by passing the ISO9001 quality management system certification, it has Class A qualifications for solid mineral exploration and geological experiment testing(rock mine identification, rock mine testing, metallurgical trial test). With its focuses on cooperating with the National Geological Survey Bureau to carry out mineral resources usability evaluation, it also assumes responsibilities of developing new technologies, new methods, and new techniques for minerals comprehensive utilization, as well as finding resources and improving the comprehensive resources utilization and guarantee. What is more,  it has provided the industry with long-term scientific research such as mineral processing, metallurgy, geological exploration, rock mine identification, and rock mine analysis and testing, turning poor mines into rich ones, the single one into multiples.
