Vacuum nitrogen filling drying oven, energy-saving and efficient nitrogen filling oven

High temperature vacuum nitrogen filled oven for rapid drying. Product features:

Vacuum function: By reducing internal pressure, lowering boiling point, and improving drying efficiency.

Nitrogen flushing: By flowing nitrogen into the box, an oxygen free environment is maintained to prevent moisture or oxidation of items.

Precise temperature control: The temperature control system ensures the stability and accuracy of the drying process.

◆ Shell material:

Made of high-quality cold-rolled steel plate reinforced design, with a streamlined appearance and overall sturdy and durable. Surface coated with environmentally friendly metallic paint

Reasonable, corrosion-resistant, scratch resistant, and aesthetically pleasing.

◆ Studio materials:

Made of high-quality stainless steel plates, reinforced with structural design, polished for durability. Curved corners for convenient hygiene

Clean up.

◆ Observation window:

Tempered steel, double-layer glass door observation window, the experimental process is clear at a glance.

◆ Thermal insulation material:

The insulation material between the studio and the outer box is high-quality ultra-fine glass fiber insulation cotton, with good insulation effect and insulation layer thickness:70mm,

High performance insulation structure, with inner cavity, inner shell, ultra-fine glass fiber, aluminum reflective aluminum foil, air interlayer, and inner liner from inside to outside

Less heat loss. The inner and outer compartments, as well as the door structure, greatly reduce the heat transfer from the inner cavity. High performance is used between doors and frames

The rubber sealing structure of the sealing material has good sealing, high temperature resistance and aging resistance.

◆ Temperature Controller:

The intelligent temperature controller adopts electromagnetic compatibility design and user-friendly menu design, with precise and stable temperature control. Direct input and display control

Temperature, heating status, timing.Overtemperature alarm and automatic cut-off of heating power supply. adoptPT100Platinum resistance sensor

◆ Heating method:

Adopting a flat nickel chromium alloy electric heater, evenly distributed on the outer walls of the working chamber to ensure good temperature uniformity inside the box.

◆ Safety device:

Over-temperature alarm,Insufficient phase protection,overcurrent protection,Fast-acting fuse,Grounding protection.

Product Structure Features

◆ The box body is reinforced with high-quality cold-rolled steel plate design, and the surface is coated with electrostatic powder coating, which is hard and firm, and has anti rust ability.

◆ The studio is made of high-quality stainless steel plates, with rounded corners, smooth, fluent, and easy to clean.

◆ The space between the box and the workspace is filled with ultra-fine glass wool insulation material, which has good insulation function, effectively ensuring stable and accurate temperature inside the box and its impact on the usage environment.

◆ The box door is made of double-layer tempered glass structure, which can clearly observe the heated items inside the box and has good insulation effect. Can effectively prevent burns to operators.

◆ A heat-resistant rubber sealing ring is installed between the studio and the glass door to ensure a high degree of vacuum inside the box.

◆ The heater is installed on the outer surface of the studio to maximize the uniformity of temperature inside the box and facilitate indoor cleaning.

◆ The temperature control is manufactured using microcomputer intelligent digital technology and has industrial capabilitiesPIDSelf tuning and four digit doubleLEDWindow indication function, high temperature control accuracy, anti-interference ability, and very convenient operation (see detailed controller instructions for details).

Product Instructions

◆ Open the box door, place the items to be processed on the shelf inside the box, and close the box door. And close the vent valve, open the vacuum valve, connect the vacuum pump to extract air, so that the vacuum degree inside the box is less than133PaThe vacuum gauge indicates a value<-0.1MＰa）Close the vacuum valve and turn off the power supply of the vacuum pump.

◆ Connect the power supply, insert the power plug into the power socket, and place the power switch on the panel in the "on" position. At this time, the instrument panel will display a number

Word display indicates that the device has entered a working state.

◆ Set the desired temperature inside the box by operating the temperature controller.

◆ The instrument starts working, and the temperature inside the box gradually reaches the set value. After the required drying treatment time, the processing work is completed.

◆ Turn off the power, wait for the temperature inside the box to approach the ambient temperature, open the vent valve, and release the vacuum inside the box. Open the box door and take out the item.

Please note: When opening the door to retrieve items, pay attention to the temperature inside the box to avoid burns. Special attention should be paid to handling flammable materials, which must be cooled to a certain temperature

Only when it is below the ignition point can air be introduced, otherwise it may cause combustion.
