| Overall Dimension (Approx.) | 1150mm (L) × 1150mm (W) × 2300mm (H) |
| Temperature Range | Adjustable from room temperature to +800℃ |
| Base Frame | 1 piece of 310 stainless steel base frame |
| Temperature Fluctuation | ≤±1℃ |
| Temperature Uniformity | ≤±3℃ (no-load) |
| Heating Rate | ≤10℃/min (no-load) |
| Shell Temperature | Temperature rise does not exceed ambient temperature +30℃, except around the door |
| Circulating Air Mode | Forced air circulation in multiple directions: up, down, left, and right |
| Power Supply | Three-phase five-wire system, 380V, 50HZ |
| Total Power | 12KW |
| Shell Material | Made of 2.0mm thick Q235 cold-rolled steel plate by bending and welding |
| Surface Treatment | 1. Surface grinding, polishing, and phosphating (to enhance corrosion resistance of metal and paint adhesion); 2. High-temperature spray coating (large ripple type) for rust and corrosion resistance; 3. Color: 7035 |
| Inner Chamber Material | Made of SUS310S stainless steel plate, ensuring a clean, dust-free, rust-resistant, and easy-to-clean inner chamber; the 四周 of the inner chamber is reinforced with stainless steel square tubes |
| Sealing Material | Sealing strips are made of high-temperature resistant ceramic rope, which is heat-resistant and non-deformable; the door and inner chamber adopt a double-layer sealing structure to enhance sealing effect |
| Feet | 4 pcs of 100mm feet welded at the bottom of the cabinet for easy forklift movement |
| Air Circulation Motor | 1 unit of 0.75KW air circulation motor |
| Wind Wheel | 10.5-inch stainless steel centrifugal wind wheel |
| Heater | Quartz glass with resistance wire (material: Ocr27AL17M02), distributed on both sides of the electric furnace |
| Air Heating Mode | Air enters the heating tube air groove through the air inlet, circulates inside the electric furnace after heating, and exhaust gas is discharged through the exhaust outlet |
| Temperature Controller | Adopts Xiamen Yudian 30-segment program intelligent digital display instrument, which can set program heating and cooling, with built-in alarm function and PID automatic tuning calculation output for precise control |
| Over-Temperature Protection Controller | Intelligent digital display temperature controller; automatically cuts off the heating power when the temperature exceeds the set value |
| Number of Temperature Zones | 1 zone, K-type thermocouple |
| Automatic Constant Temperature | 1. The temperature controller automatically calculates the input power through PID according to the user-set temperature; 2. The closer to the set temperature, the smaller the output power, achieving constant temperature control and energy saving |
| Over-Temperature Alarm | Automatically cuts off the heating power when the actual detected temperature exceeds the set value of the over-temperature protection controller, providing double protection |
