Operating Flowchart & System Overview 

This advanced system ensures superior transformer oil purification by leveraging high-vacuum, low-temperature technology with a fully automatic operational workflow. Designed to meet stringent European standards, it guarantees optimal oil quality while maintaining environmental compliance and operational efficiency.

• Process Initiation: System starts via PLC-controlled HMI interface.
• Suction Pump Activation: CE-certified oil pump extracts oil from the transformer tank into the filtration unit.

• Low-Temperature Heating: Oil passes through a stainless-steel heat exchanger to raise the temperature (max 60°C).
• Safety Control: Over-temperature sensors ensure no degradation of oil cellulose.

• Coarse Filtration: Removes large impurities and sludge (>10 microns) via primary filter cartridges.
• Particle Separation: Stainless-steel mesh ensures durability and easy maintenance.

• Vacuum Chamber Operation: Oil enters the vacuum chamber, where high vacuum (<1 mbar) removes dissolved gases and moisture.
• Water Extraction: Evaporated water is condensed and discharged.
• Degassing: Achieves dissolved gas levels below 0.1% volume.

• Fine Filtration: Filters oil to remove particles down to 1 micron, ensuring compliance with IEC 60296 standards.
• Moisture Removal: Achieves moisture content below 10 ppm.

• Automatic Recirculation: Oil is reintroduced to the transformer to achieve equilibrium by multiple passes.
• Flow Rate Control: VFD-regulated pump adjusts flow rates for precise control.

• Purified Oil Discharge: Fully processed oil is discharged back to the transformer or storage tank.
• Real-Time Monitoring: HMI displays oil parameters, including dielectric strength, moisture levels, and flow rate.
• Auto Shut-off: System halts automatically once the desired oil quality is achieved.

• High-Efficiency Filters: Multi-stage filtration with replaceable cartridges.
• Vacuum Pump: CE-certified rotary vane pump for high vacuum (0.01–0.05 mbar).
• Heating System: Low-watt density heaters to avoid thermal stress on oil.
• Control Panel: Siemens PLC with a 7-inch HMI for automation and data logging.
• Sensors: Temperature, moisture, and pressure sensors for real-time feedback.
• Recirculation System: Ensures oil equilibrium through repeated filtration.

• ISO 9001:2015: Quality management.
• IEC 60422: Maintenance of insulating oils in transformers.
• CE Certification: Meets safety and environmental directives.
• Directive 2010/75/EU: Low emissions and energy efficiency.

• Flow Rate: 500–12,000 liters/hour (customizable).
• Filtration Precision: Down to 1 micron, moisture <10 ppm.
• Temperature Range: Max 60°C.
• Vacuum Level: < 1 mbar.
• Power Supply: 380–415V, 50/60Hz.

This double-stage filtration system ensures unparalleled oil purification efficiency, aligning with European standards for safety, quality.

We, DK Systems, are a leading Manufacturing a Vacuum Drying Oven with Auto Transformer involves mechanical fabrication, electrical design, vacuum system integration, heating system implementation, and automation controls. Below is a step-by-step guide to the manufacturing process:

Step 1: Define the Technical Specifications

Before starting, define the design parameters based on customer requirements:

• Internal Dimensions: (e.g., L-4200 mm, W-2950 mm, H-2700 mm)
• Temperature Range: Up to 150°C
• Heating Method: Air Heating System with Auto Transformer
• Vacuum Level: 0.1 to 10 mbar (Adjustable based on transformer insulation drying requirements)
• Door Mechanism: Mechanical clamping system for vacuum sealing
• Trolley System: Motorized trolley for material handling
• Control System: PLC-based automation for temperature, vacuum, and timing control
• Material: MS, depending on application requirements

Step 2: Fabrication of the Oven Body

1. Structural Frame Manufacturing

• Use MS/SS304/SS316 plates and profiles for the frame
• Weld and fabricate the outer and inner walls with insulation gaps
• Design and manufacture supporting legs and base for stability
• Ensure proper sealing flanges to maintain vacuum integrity

2. Insulation Layer Installation

• Install high-temperature ceramic wool insulation between inner and outer walls
• Use rock wool or glass wool for heat retention
• Cover insulation with stainless steel cladding to prevent heat loss

Step 3: Heating System with Auto Transformer

1. Auto Transformer Design & Selection

• Select a step-up/step-down auto transformer based on heating element voltage requirements
• Use a temperature controller (PID Controller or PLC) to regulate power supply
• Integrate thermal sensors (RTD/PT100) for precise temperature monitoring

2. Air Heating System

• Install stainless steel heating elements (electric resistance heaters) inside the oven
• Use circulation fans to distribute hot air evenly
• Implement over-temperature protection system to avoid overheating

Step 4: Vacuum System Integration

1. Vacuum Pump Selection

• Choose a high-capacity rotary vane vacuum pump (or oil-sealed pump)
• Ensure the pump achieves 0.1 to 10 mbar vacuum level
• Install vacuum sensors and a digital vacuum gauge for monitoring

2. Vacuum Chamber Sealing

• Use silicone rubber gaskets for airtight sealing
• Implement mechanical clamping door system for secure vacuum hold
• Design pressure relief valves to prevent chamber overpressure

Step 5: Trolley System & Door Mechanism

1. Motorized Trolley System

• Use a heavy-duty steel rail system inside the oven
• Install a motorized trolley with rollers for easy transformer loading/unloading
• Integrate limit switches for safe operation

2. Door Clamping System

• Use a pneumatic or mechanical clamping mechanism to ensure a vacuum-tight seal
• Design hinged or sliding doors based on space constraints
