Company PR
Our company primarily develops and manufactures testing equipment for production plants. In addition to test equipment for the high-temperature/high-pressure and vacuum fields, we also are involved in a broad range of other fields including petrochemicals, new energy sources, food chemistry, the nuclear power industry, methanol synthesis, textile chemistry, steel, paper, and various solvents. All of this equipment requires extremely high levels of quality and accuracy. We possess a large number of products that are the only ones of their kind in the world, and the expertise we have developed through producing them, and the unique natures of these products, form the foundation of our advanced engineering capabilities. We also apply specific areas of this expertise for original in-house development of various kinds of equipment.
