AVIC Hebei Hebei Anji Hongye Group's subsidiary, Hebei Hongye Yongsheng Automotive Heater Co., Ltd., followed the pace of the market, increased research and development of automotive heating products, spending huge sums invested in comprehensive environmental simulation laboratory projects. The laboratory can provide the following experimental simulation environment for cars, passenger cars, trucks and special vehicles, special vehicles, and construction machinery vehicles: simulation of driving wind, cold start test of automobile, high and low temperature test of automobile, simulation test of automobile frost and fog, and vehicle It is harmful to its gas simulation tests and automobile emission tests. The main part of the project and the refrigeration system have been installed. At the end of May 2013 , the commissioning and acceptance were completed.  After the laboratory is completed, it can solve high and low temperature tests of various vehicles including military special vehicles, various performance tests of automotive heaters and related products, and provide basis for product development, production, and improvement. Meanwhile, the laboratory’s The construction can gather and train high-level talents in research and development of automotive heaters, and conduct technical exchanges with related scientific research institutes and enterprises at home and abroad. WNS series gas and oil fired boiler is package type full automatic horizontal three pass fire tube wet back structure boiler. The boiler can produce hot water, saturated steam or superheated steam.
