Product Features

1. Integrated, Compact Design with a 1-Cubic-Meter Chamber

The unit features a compact, integrated design combining the control system with the furnace body. The chamber measures 1000 mm (W) × 1000 mm (D) × 1000 mm (H), providing a 1-cubic-meter volume—ideal for drying or heat-treating large batches of workpieces or oversized samples.

2. Top-Mounted Hot-Air Circulation System (Temperature Uniformity ≤±5°C)

Equipped with a top-mounted hot-air circulation system, the unit utilizes a 0.75 kW motor driving a 10.5-inch 310S stainless steel centrifugal fan. A variable-frequency drive (VFD) allows for stepless speed control. An optional PLC integration feature is available, enabling the fan speed to be synchronized with the temperature profile. Temperature uniformity is maintained at ≤±5°C (depending on chamber dimensions), ensuring consistent heat distribution throughout the large-volume chamber.

3. Heating via High-Temperature Alloy Resistance Wires (Side and Bottom Placement)

High-temperature alloy resistance wires are positioned along the sides and bottom of the chamber, creating a three-sided heating field. The system offers a temperature control precision of ±1°C (via integrated circuitry, with no overshoot) and a constant-temperature stability of ±1°C. The maximum heating rate is ≤20°C/min.

4. 180° Side-Opening Door and Bottom-Mounted Rail-Guided Trolley

The furnace door features a 180° side-opening hinge design with an elastic locking system that compensates for thermal expansion, ensuring a reliable seal even at high temperatures. A rail-guided trolley platform is provided at the base to facilitate the loading and unloading of large or heavy workpieces. The sample rack is constructed from 316 stainless steel, suitable for long-term use at temperatures up to 700°C.

Frequently Asked Questions (FAQ)

1. What are the operating temperature range and chamber dimensions of this industrial heat treatment furnace?

The equipment has an operating temperature range from room temperature to 800°C. The chamber dimensions are W1000 × D1000 × H1000 mm. A K-type thermocouple is used for temperature sensing.

2. How does the equipment ensure temperature uniformity within the chamber?

The unit features high-temperature alloy resistance heating elements evenly distributed along the sides and bottom. A hot-air circulation system, equipped with a 310S stainless steel centrifugal fan, is installed at the top of the chamber to promote the circulation of hot air. This achieves a temperature uniformity of ≤±5°C; actual performance may vary depending on the load and specific operating conditions.

3. Is the hot-air circulation speed adjustable?

Yes. The circulation fan is powered by a 0.75 kW motor, with speed controlled steplessly via a variable-frequency drive (VFD). An optional PLC integration feature is also available, allowing the fan speed to be synchronized with the programmed temperature profile.

4. Can the equipment be programmed for automatic heating and holding cycles?

Yes. The system supports 50-segment program control, allowing for the configuration of heating, holding, cycling, pausing, and resuming processes. Program parameters can also be edited while the unit is in operation. The maximum heating rate is ≤20°C/min.

5. What is the warranty period for this equipment?

The entire unit comes with a 1-year warranty. Heating elements are not covered under the standard warranty; however, should a heating element fail due to natural wear or defect within 3 months, it will be replaced free of charge in accordance with the agreed terms.
