Product Performance Calculating Software

1. Used in the refrigeration industry shell and tube heat exchanger uses the refrigeration industry WIELAND software to calculate the heat transfer performance of the heat exchanger. The WIELAND software includes R22, R134a, R404A, R407C, R410A, R502, R507, R717, R245fa and other media. :

2. The heat exchangers used in chemical, petroleum and other industries use the American heat transfer software HTRI to calculate the heat transfer performance of the heat exchangers. All heat exchangers are tested for heat transfer performance through a performance test platform to ensure the margin of heat exchanger use and meet customer needs.

3. The strength calculation of heat exchangers and pressure vessels of various tanks uses the pressure vessel industry SW6-2011v4.0 software to calculate its strength, and passes the inspection of Guangzhou Quality and Technical Supervision Bureau and leaves the factory.
