Frequently Asked Questions
Certainly. Industrial drying is a highly specialized process. Qungan is equipped with a dedicated material testing laboratory, and we strongly recommend that you send material samples. Our R engineering team will conduct actual tests based on your material characteristics—such as initial moisture, final moisture, thermal sensitivity, and viscosity—and use that data to tailor the most suitable drying system and parameters for your production line.
Energy efficiency is a core advantage of Qungan equipment. Our drying systems utilize innovative hot air circulation and high-density insulation technology, which, compared to traditional dryers, can effectively reduce heat loss and save up to 15% to 30% in energy consumption. Additionally, our systems support various heat source inputs (steam, electricity, natural gas, or biomass) and integrate PLC intelligent temperature control systems to dynamically adjust output, avoiding unnecessary energy waste.
The design and manufacture of all Qungan drying systems strictly follow global industrial standards. Our factory is ISO 9001:2015 certified. Depending on your region and industry requirements, we can customize equipment to comply with CE directives, ASME standards, or explosion-proof certifications (such as ATEX/Ex) for flammable and explosive environments, ensuring safe and compliant operation in chemical, pharmaceutical, or food processing plants.
We provide a 12-month standard warranty from the date of installation and commissioning or shipment. During this period, any component damage caused by manufacturing defects will be replaced free of charge. For global after-sales, we offer “24-hour online remote diagnosis” to quickly resolve software or parameter issues. If necessary, our experienced field engineers can also travel overseas to provide installation guidance, commissioning, and complete operational training to ensure stable production at your plant.
