Vacuum Drying Oven Performance Features
– Serves as an atmosphere protection box and nitrogen drying oven
– Equipped with a vacuum pump and vacuum tube for vacuum testing
– Rapidly dries colloids, powders, or other difficult-to-dry granular samples
– Dries various complex mechanical components or other porous samples without leaving residual substances after cleaning
– Made of stainless steel, the rectangular working chamber maximizes the effective volume.
PW-CV vacuum drying oven is designed specifically for drying heat-sensitive, easily decomposable, and easily oxidizable materials. It is capable of being filled with inert gases, allowing for rapid drying of even complex items. The rectangular working chamber maximizes the effective volume. The heating elements are U-shaped and surround the outer wall of the chamber, with insulation cotton filling for thermal insulation. The microcomputer temperature controller can automatically adjust control parameters based on the ambient temperature and the load size, ensuring reliable temperature control accuracy. The tempered, bulletproof double-layer glass door allows for a clear view of the objects inside the chamber. The tightness of the box door can be adjusted, and the overall molded silicone door seal ensures a tight seal. The working chamber is made of stainless steel, and storage, heating, and drying are all carried out in an oxygen-free or inert gas-filled environment, preventing oxidation. Equipped with a vacuum pump and vacuum tube, it can be used for vacuum extraction experiments.
Chamber Structure and Materials
– Outer Chamber Material: The outer chamber is made of high-quality cold-rolled steel, treated with a phosphate skin membrane and salt, then high-temperature sprayed. It features double-layer tempered, bulletproof glass doors with blue doors and a computer grey body.
– Working Chamber Material: The working chamber is made of stainless steel with reinforcement, including two layers of stainless steel shelves and racks.
– Insulation Material: High-density glass fiber cotton is used for insulation, filled in the front, back, left, right, top, and bottom layers of the chamber.
– Sealing Material: The door and the working chamber are sealed with high-temperature resistant, high-elasticity silicone rubber seals to ensure the sealing of the working chamber.
– Temperature Probe Port: The PT100 sensor enters the outer side of the inner chamber from the upper rear of the chamber.
– Terminal Block: The terminal block for the heating elements is located at the lower left rear of the chamber.
– Controller: Located on the left side of the chamber, it includes a pressure gauge and a vent valve, with an integrated control system and compensating cables connecting to the sensor.
– Heating Elements: Stainless steel electric heaters.
– Overall Weight: Approximately 62KG.
– Standard Packaging: Cardboard box.
Temperature Control System and Features
– To ensure vacuum integrity, the sensor is located on the outside of the inner chamber.
– PT100 high-responsive thermal sensors combined with environmental scanning microprocessor chips form a high-precision, high-intelligence temperature control characteristic.
– Built-in temperature calibrators can adjust minor temperature errors. The system can automatically alarm when the displayed temperature deviates from the set temperature, and it has automatic power-off protection in case of heater malfunction.
– It features power failure recovery, allowing the device to automatically resume the original set program for rapid temperature stabilization when external power is restored. It has parameter memory function to avoid cumbersome settings, with capabilities for automatic shutdown, timed operation, power-on recovery, parameter memory, parameter password protection, and temperature display calibration.
– The timer function allows for any setting of working time from 1 minute to 9999 minutes in 30 segments, and the set display window is closed when the timer ends. (The device starts when the temperature is reached, and automatically shuts off when the time is up.)
– Both set parameters and actual parameters are clearly displayed. Set temperature, measured temperature, and timer time are all visible, with a modular design for high-temperature tracking. When the measured temperature deviates from the allowed range, the instrument will sound (light) alarm and automatically cut off the heating.
Heating System
– The heater is located on the outer wall of the inner chamber and is controlled by the sensor response control system.
– The heating output of the heater is controlled by a microcomputer within the intelligent instrument.
Safety Protection System
– Fusible protection device.
– Over-temperature protector for the working chamber, with an upper limit over-temperature alarm and heating stop function.
– Leakage protection and electric shock protection to ensure safety during use.
Main Components
– Intelligent control instrument.
– Thyristor.
– Sensor.
– Stainless steel heater.
– Vacuum pump.
