R & D
Halley has a group of outstanding technical research and development personnel, carrying on R & D activities in the heat energy efficiency, mechanism, industrial design, etc. and explores and advances the comprehensive promotion of new products positively in various aspects performance through cooperation with Chinese First-class University, and research institutes. Halley insists the research and development idea of” Base on China, create the world technology”, derives and creates the acme scientific and technical payoffs through the unremitting endeavor.
For many years, Halley's technological innovation continuously impels the Chinese plate heat exchange technology development. Halley plate heat exchanger developed independently and other products are tested by the national authority's plate heat exchanger surveillance and testing center, each qualitative index is superior to the domestic similar product, praised as Ningbo high and new technology achievement transformation project, Ningbo high-tech product. This product has been widely applied in heating and refrigeration fields, which changes the tradition of using foreign products in central air conditioning, wall furnace, heat pump, and so on.
Material selection
The material of the complete machine is composed of 316L (ultra low-carbon stainless steel) and the pure copper (99.9%), and the suppliers if these material by must pass the ISO90000 system appraisal.
Technique
Halley brazing heat exchanger products all adapt world leading vacuum brazing and control technology, each procedure strictly follows ISO9000 to set up quality management system, and obtained the certification of German TUV company, which form the remarkable performance of Halley heat exchanger in every aspect.
Performance testing
The brazing heat exchanger is classified as the pressure vessel, which means that it has very high request to the intensity and quality. Weld point seal situation, namely, the seal property and intensity of the heat exchanger, although cannot be obtained through the theoretical calculation, must be confirmed through the test. In order to guarantee the correct test on heat exchange, one must have wide energetics knowledge, such as analysis and measure technique, as well as practical experience in the latest technique equipment.
Halley products have passed the strict nitrogen hydrostatic testing, he helium leak detection, the destructive test and other items before ex-work. After they are tested to be qualified, we can provide the test certificate of quality to customers who place the order to buy the heat exchanger.
