Dong Hwa Hi-Tech specializes in the design and manufacture of high-performance industrial heating systems engineered to meet the demanding requirements of modern production environments. With advanced automation facilities and decades of accumulated know-how, the company delivers a comprehensive lineup of heating solutions—each designed for efficiency, durability, and precise temperature control.
At the core of Dong Hwa Hi-Tech’s manufacturing expertise is its ability to provide application-specific heating solutions, ranging from continuous-process heaters to precision-controlled systems for specialized industrial use.
Hot Air Heaters are designed for drying and pre-treatment processes where direct heater installation is difficult. Commonly used in plating lines, wire processing, and paper drying, these systems provide stable hot air circulation ideal for continuous production environments.
For applications requiring advanced thermal control, Induction Heaters utilize electromagnetic heating technology to efficiently heat rollers and components that conventional heaters cannot handle. These systems are custom-engineered according to material, temperature, and capacity requirements, making them essential for textile stretching and film processing lines.
The High-Precision Vacuum Block Heater is developed for processes that demand uniform heat distribution and rapid temperature response. By minimizing temperature deviation, this heater ensures consistent quality in textile stretching and other precision thermal applications.
Heating Cabinets provide a controlled thermal environment using forced hot air circulation. Designed for energy efficiency and high productivity, they are widely used for heat treatment of rubber, plastics, dyes, and electrical or electronic components, supporting multi-stage loading and heavy materials.
Dong Hwa Hi-Tech’s Immersion Heaters deliver exceptional thermal efficiency by directly heating liquids or gases. Engineered with safety mechanisms and application-specific load density, these heaters are widely used for thermal oils, nitrogen, steam systems, and as heat sources for boilers and chip dryers.
For high-contact, shape-specific heating, Molding Heaters are cast in materials such as aluminum or brass to match the exact geometry of molds and equipment. Their excellent thermal contact and long service life make them ideal for extruders, hoods, and external piping in textile and industrial machinery.
Sheath Heaters offer unmatched versatility. By embedding heating wires within insulated metal tubes, these heaters can be bent into various shapes while maintaining high durability and thermal efficiency. They are commonly applied in metal heating, ovens, dryers, laboratory equipment, and casting systems.
To protect critical electrical components, Space Heaters are designed to prevent moisture buildup in motors, control panels, and breaker systems. By maintaining insulation integrity during downtime, these heaters significantly extend equipment lifespan and reliability.
For large-scale or experimental operations, Pilot-Type Large Heaters are custom-built to support pilot plants and heavy industrial processes. These systems demonstrate Dong Hwa Hi-Tech’s capability to scale heating solutions while maintaining stability and safety.
Finally, Dry Oven Heaters provide complete drying and curing solutions through controlled heating cycles. Available in sealed or tunnel configurations and compatible with multiple heat sources, these systems support coating, painting, and moisture removal processes across industries.
Together, Dong Hwa Hi-Tech’s product portfolio represents a complete heating ecosystem—engineered, manufactured, and tested in-house. By combining technical precision, customization capability, and proven reliability, the company continues to serve as a trusted heating solutions partner for industries worldwide.
