In this project, we provided the customer with a highly efficient insulation air conditioning insulation duct system, which is closely integrated with the grain chiller to optimize the temperature and humidity control of the grain storage environment. Through in-depth communication with customers, we designed a special thermal insulation duct to meet the needs of grain chillers, using high-quality thermal insulation materials to ensure that the system maintains stable performance in low temperature and high humidity environment. Our factories are responsible for production and ensure that products are delivered to customers quickly and safely. Finally, the successful application of the thermal insulation duct system has significantly improved the preservation effect of grain and reduced energy consumption, and our air conditioning insulation duct has also been highly recognized by customers.
