I. The HRF216-07N hot air debinding furnace is a high-end thermal processing equipment featuring compact structure, comprehensive functions, and intelligent control. It is particularly suitable for production processes with stringent requirements for temperature uniformity, temperature control accuracy, and process safety.

Model: HRF216-07N

Application: Mainly used for heat treatment processes such as drying, curing, and degreasing of semiconductors, electronic components, and related materials.

II. Operating temperature range: The standard operating temperature ranges from room temperature (RT) to 650°C, with a maximum test temperature of 700°C (typically used for extreme testing and not recommended for long-term use).

•Effective furnace dimensions: The internal workspace for placing workpieces measures 600 mm (width) × 600 mm (height) × 600 mm (depth), suitable for medium-sized batch processing.

•Number of temperature zones: The equipment features a single-zone structure, meaning the entire furnace interior functions as a unified heating and temperature control area, ideal for processes requiring high temperature uniformity.

•Temperature control points: 1 control point for precise regulation of the actual temperature inside the working chamber.

•Programmable temperature segments: Supports 4×16 segment program control, allowing up to 64 steps of different temperature and time combinations to achieve complex heating, holding, and cooling process curves.

•Heating method: Utilizes stainless steel heating tubes as heating elements, ensuring uniform heating and long service life, suitable for continuous high-temperature operation.

•Air circulation system: Equipped with a centrifugal fan wheel to enhance temperature uniformity through forced hot air circulation, minimizing temperature variations across different furnace zones.

•Furnace structure: The furnace body features a double-layer stainless steel shell with full-fiber insulation filling, offering excellent thermal retention and durability while reducing heat loss for significant energy savings.

•Temperature uniformity: Within the 300°C to 600°C range, under a 1-hour steady-state test with an empty furnace, temperature variations are controlled within ±5°C, meeting most process requirements for temperature uniformity.

•Temperature control instrument: Uses an imported Japanese intelligent temperature controller known for high reliability and stability. The device supports PID auto-tuning for precise temperature control.

•Temperature measurement and control accuracy: Employs K-type thermocouples for temperature detection, achieving high control accuracy with single-point stability of ±1°C, suitable for high-precision processes.

•Safety features: Includes multiple protective functions such as high-temperature alarm and thermocouple failure alerts to ensure safe operation and prevent losses due to temperature runaway.

•Heating power: Maximum heating power of 24 kW enables rapid heating for efficient production needs, while standby power consumption can drop below 12 kW during idle insulation, aiding energy conservation.

•Exhaust system: Features an adjustable exhaust port for manual regulation to vent furnace gases or adjust internal pressure based on process requirements.

•Power supply requirements: Operates on a 380V (±5%), three-phase, five-wire system with a 50 Hz frequency and 50 A current. Wiring should follow standard color codes: live wires (yellow, green, red), neutral (blue), and ground (yellow-green).

•Surface temperature rise: During operation, external temperature rise is limited to within 35°C, ensuring a safer and more comfortable exterior to reduce burn risks.

•Equipment weight: Total weight is approximately 1000 kg, classified as heavy industrial machinery requiring consideration for lifting and load-bearing during installation.

•Overall dimensions: External dimensions measure approximately 1250 mm (width) × 1900 mm (height) × 1500 mm (depth), necessitating adequate surrounding space for operation and maintenance during installation. 
 

III. Intelligent Control Features

•The equipment utilizes an intelligent programmable temperature controller, supporting 4×16 segment program control. Users can preset multiple heating rates, dwell times, and other parameters to flexibly adapt to different process requirements.

•The temperature controller receives real-time temperature signals from a Type K thermocouple and regulates the power output via a power adjustment module, enabling precise control of heating power.

•The intelligent instrument features PID auto-tuning, automatically optimizing control parameters based on furnace conditions to ensure temperature accuracy and system stability.

•High temperature control precision, achieving stability within ±1°C under steady-state conditions, making it ideal for temperature-sensitive processes.

•Multiple alarm and protection functions are provided, including high-temperature limit alarms and thermocouple fault alarms, ensuring timely operator notification during anomalies to prevent equipment or product damage.

IV. On-Site Installation and Preparation Requirements

To ensure the HRF216-07N hot air debinding furnace operates safely, stably, and efficiently, customers must prepare the following environmental and supporting facilities before installation:

1. Environmental Conditions

   •Operating ambient temperature should be maintained between 0 and 40°C.

•Relative humidity should not exceed 80% RH.

•The environment must be free of corrosive gases (e.g., acid mist, alkaline vapors) and strong air currents to avoid disrupting furnace temperature stability.

1. Gas Supply Requirements (Depending on Process Needs)

   •Use clean, oil-free compressed air or high-purity nitrogen (especially for oxidation-sensitive processes).

•Gas purity must be ≥99.999% (5N nitrogen) to avoid contaminating products.

•Inlet gas pressure range: 0.2-0.4 MPa.

•Gas consumption: approximately 3-7 m³/h; ensure a stable and continuous supply.

Gas configuration may be simplified if no special atmosphere is required.

1. Water Supply Requirements (If Equipped with Cooling System)

   •Water must be clean and non-corrosive.

•Water temperature should not exceed 23°C to maintain cooling efficiency.

•Water pressure range: 0.2-0.4 MPa.

•Flow rate: 2-6 L/min; verify if water connection is needed based on cooling module configuration.

Note: Not all HRF216-07N units include a water cooling system.

1. Ventilation System

   •An external exhaust system (≥10 m³/h capacity) must be connected to remove furnace gases and maintain a safe workspace.

2. Floor Requirements

   •Installation surface must be level, vibration-free, and structurally robust (load capacity >300 kg/m² to support the ~1000 kg equipment and dynamic loads).

3. Power Supply

   •Three-phase, 5-wire AC power: 380V (±5%), 50 Hz.

•Recommended capacity: ≥32 kVA to ensure stable operation.

•Wiring standards:

• Phase lines: Yellow, Green, Red

• Neutral: Blue

• Ground: Yellow-Green

Professional electrical installation is strongly advised for safety compliance.

1. Space Requirements

   •Minimum installation area: 2000 mm (W) × 3000 mm (D) × 3000 mm (H).

   •Recommended footprint: >6 m², with adequate clearance for access, maintenance, and wiring.
