About Variable-Pressure Vacuum Drying Equipment

Variable-pressure vacuum drying equipment

Description of variable-pressure vacuum drying equipment
This kind of furnace adopts variable-pressure drying principle suggested by Dr. Moll from Germany, specialized for drying transformer and power capacitor bodies. Comparing to conventional vacuum heating drying method, drying duration of this variable-pressure type has been saved about 30-45%.

Application of variable-pressure vacuum drying equipment:

Drying transformer bodies in grade 10~110kV, capacity less than 100,000kVA
Drying transformer windings in 110~500kV grade
Drying current transformer and potential transformer bodies in 110~500kV grade
Drying power capacitors
Drying other electrical materials

Main features of variable-pressure vacuum drying equipment:

Compact structure, small occupation
High productivity: when drying one 110kV, 40000KVA transformer body, it will take only about 50 hours, close to that by kerosene vapor-phase drying equipment
Heating system is controlled by power control module, assuring even and stable temperature; Real power consumption during temperature-keeping is only about 35% of total power; There is no fluctuation of heating load and thus reduces actual heating power very much.
PLC control, high automation, more stable and reliable
Special baffle valves for vacuum drying, better vacuuming performance

Efficient Drying Performance

Thanks to its advanced variable-pressure control system, the VPVD-800 delivers uniform and rapid drying results, supporting applications requiring moisture-sensitive handling. The chamber, with a 432-liter capacity and three adjustable shelves, allows flexibility in sample arrangement for diverse laboratory and industrial needs.

Enhanced Safety and Monitoring

Safety is paramount with this equipment. The unit comes with an over-temperature protection system and safety door interlock. Its toughened glass viewing window enables real-time monitoring, while the digital LED display ensures easy parameter checks and adjustments during operation.

FAQs of Variable-Pressure Vacuum Drying Equipment:

Q: How does the variable-pressure system improve the drying process?

A: The variable-pressure vacuum system allows precise control of pressure conditions within the drying chamber, enhancing the removal of moisture from heat-sensitive and delicate materials. This results in faster drying times and optimal retention of product quality.

Q: What types of vacuum pumps are compatible with the VPVD-800 model?

A: This equipment is compatible with both oil rotary and diaphragm vacuum pumps, providing flexibility to match various application requirements and user preferences in the pharmaceutical, chemical, and laboratory sectors.

Q: When should the optional humidity control feature be used?

A: The optional humidity control is beneficial when specific moisture levels must be maintained or gradually changed during the drying cycle, which is critical for certain pharmaceutical formulations and high-precision laboratory experiments.

Q: Where can this vacuum drying equipment be most effectively utilized?

A: The VPVD-800 is ideally suited for pharmaceutical manufacturing, chemical processing, and laboratory research facilities, especially where controlled environment drying of sensitive or high-value materials is required.

Q: What process controls are available to ensure precise drying operation?

A: The instrument features a digital PID controller for accurate temperature regulation, a programmable timer ranging from 0 to 9999 minutes, and a digital LED display for easy monitoring and adjustment of critical parameters.

Q: How does the safety door interlock benefit users?

A: The safety door interlock mechanism ensures the equipment operates only when the door is securely closed, preventing accidental exposure to high temperatures or vacuum conditions and reducing risk during operation.

Q: What are the main benefits of using a stainless steel chamber with polished finish?

A: A stainless steel 304 chamber with a polished surface provides excellent corrosion resistance, easy cleaning, and maintains hygienic conditions, making it perfect for pharmaceutical and laboratory applications requiring strict contamination control.
