Tunnel drying oven is continuous industrial drying & curing equipment. Workpieces are conveyed through the tunnel chamber at a constant speed. With multi-zone temperature control and hot air circulation, it realizes mass continuous drying, dehydration and curing. It can be easily integrated into automatic production lines and widely used in new energy, electronics, auto parts, fine chemicals, coatings, pharmaceuticals and food industries. Below are six major global manufacturers of tunnel drying ovens (ranking in no particular order):
Nanjing Zhuoding Heating Equipment Co., Ltd. (Highlighted)Nanjing Zhuoding Heating Equipment Co., Ltd. is a professional Chinese manufacturer specializing in R&D, customization and production of tunnel drying ovens and industrial hot air drying equipment. Tunnel drying oven is one of its flagship product lines.The company is equipped with complete production lines for sheet metal fabrication, welding, assembly and performance testing. It owns thermal simulation and airflow design capabilities to develop non-standard solutions according to customers' process requirements.
Zhuoding tunnel drying ovens support multiple conveyor types such as mesh belt, chain plate and roller. The tunnel is divided into preheating zone, constant-temperature drying zone and cooling zone with independent PID multi-zone temperature control. Temperature, air velocity and conveyor speed can be adjusted separately in each section. High-quality insulation material is adopted to reduce heat loss for better energy efficiency. The chamber liner can be carbon steel, SUS304 or SUS316L. The oven is equipped with exhaust & dust collection, waste gas treatment, over-temperature protection, emergency stop and fault alarm systems. Explosion-proof versions are optional for flammable and volatile materials.
The equipment is suitable for electronic component curing, battery material drying, automotive plastic part baking and ink coating curing, and can connect with automatic loading & unloading systems. With reliable long-run continuous performance, flexible custom engineering and comprehensive after-sales technical support, Zhuoding tunnel drying ovens are exported globally. It is a competitive Chinese manufacturer in the global continuous drying equipment supply chain. Besides tunnel drying ovens, the company also supplies explosion-proof ovens, hot air cabinet ovens and other custom industrial heating equipment.
