The Precision Forced Convection Drying Oven DHG9040HA, developed by our technical team over many years, integrates the advantages of German drying ovens, achieving exceptional uniformity. The oven features a sleek design with a plastic-sprayed exterior, and the control system is located at the bottom. It uses a fully automatic programmable instrument that allows control over heating rate, temperature, and multi-segment curves. The PID+SSR system ensures synchronized control, enabling consistency and reproducibility in tests and experiments. The DHG9040HA includes dual-stage over-temperature protection for reliable and safe operation, with optional signal lights indicating heating status. The stainless steel heater at the bottom releases heat through three air ducts, circulating hot air effectively for even temperature distribution. With a uniformity of up to ±1℃, this oven rivals Japanese and German models, making it ideal for industries requiring strict temperature uniformity such as electronics, rubber, plastics, and decorative materials.

Shell Material: High-quality low-carbon steel, high yield and tensile strength, robust load-bearing capacity.

External Process: Phosphating and high-temperature plastic spraying on both interior and exterior surfaces, enhancing corrosion and moisture resistance, aesthetically pleasing.

Observation Window: Equipped on the front door, made of double-layer tempered glass to reduce heat transfer and ensure safety.

Internal Material: Entirely stainless steel inner chamber, corrosion and moisture-resistant, anti-oxidation.

Shelves: Built-in support rails with two sets of stainless steel mesh shelves, adjustable height.

Insulation Material: High-density fiber cotton filled in the front, rear, left, right, top, and bottom layers for heat insulation.

Heating Element: High-temperature stainless steel heater.

Fan: Long-axis fan motor with multi-wing aluminum alloy blades.

Internal Circulation Principle: Forced air circulation by fan motor, ensuring even air distribution inside the chamber through three-point heat dissipation vents.

Temperature Sensor: High-precision platinum sensor PT100, installed at the upper rear of the chamber.

Temperature Controller: Fully automatic microcomputer temperature controller, capable of executing multiple heating modes such as uniform heating and constant temperature. It can also run multiple processes in combination, storing up to 50 process programs. The controller includes self-tuning algorithms for optimizing PID parameters based on long-term usage temperatures, maximizing heating efficiency. Built-in safety features such as over-temperature protection, alarms, over-current protection, and over-temperature protection ensure utmost safety.
