Transformer oil plays a critical role in:

• Electrical insulation

• Heat dissipation

• Arc suppression

Over time, oil becomes contaminated with moisture, gases, acids, sludge, and solid particles, which significantly reduces its insulating properties and accelerates transformer aging. The oil filtration plant removes these contaminants, ensuring safe, efficient, and long-term transformer performance.

• Moisture Reduction: ≤ 5 PPM

• Gas Content: ≤ 0.1%

• Particle Filtration: Up to 1 micron

• Dielectric Strength: ≥ 70 kV (BDV)

• Vacuum Level: ≤ 1 mbar

• Continuous Operation Capability

• PLC Automation with Touch HMI (Optional)

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

We manufacture Three Phase High Vacuum Transformer Oil Filter Machine & dehydration plants ranging from 300 LPH to 3000 LPH. Each model having 2 types mainly, single stage degassing & 2 stage degassing. Working vacuum of single stage degassing plants is less than 1 Torr. While working vacuum 2-stage plants is less than 0.2 Torr. Our machines are work on Low temperature high vacuum principle. So, running cost of our machine is very minimal.  We also manufacture tailor made plants for our customers such as transformer oil regeneration plants. Recently we have introduced the new series (HV) in addition to single stage (1V) & two stage (2V) of transformer oil filtration & dehydration plants.

The Transformer Oil Filter Machine Capacity Range : 300 LPH to 3000 LPH,General Model Name : SGEI300 Series

The Transformer Oil Filter Plant is engineered with a Low-Temperature & High-Vacuum System to efficiently purify and restore the quality of transformer oil. The primary objectives of this system are:

• Removal of sediments/sludge,
• Reduction of moisture content and dissolved gases,
• Neutralization of acidity,
  ensuring the oil's dielectric and insulating properties meet the required operational standards.

Design Highlights

1. Operator-Friendly Construction

   • All operational controls, vision ports, and valves are ergonomically placed on one side for easy accessibility.

2. Key Components

   • Heater Chamber: Maintains oil temperature between 65°C and 90°C.
   • Micron Filter: Removes larger particles and sludge (down to 1 micron).
   • Micron Filter: Captures finer particles (up to 0.5 microns).
   • Degassing Chamber: Eliminates dissolved gases and moisture under high vacuum.
   • Vacuum Pumps: Rotary high-vacuum pumps ensure efficient degassing and moisture removal.
   • Suction & Outlet Pumps: Facilitate the flow of oil into and out of the system.

3. Leak-Proof Assembly

   • All joints are sealed with nitrile O-rings in precision-machined flanges.
   • The system undergoes a rigorous pneumatic pressure test at 3 kg/cm² to ensure no leakage and to verify desired vacuum leak rates.

Operational Workflow

1. Oil Suction

   • Transformer oil is drawn into the system from the source via the suction pump.

2. Heating

   • The oil passes through the heater chamber, where it is gently heated (65°C–90°C).
   • Heating under vacuum prevents oil degradation and ensures the removal of moisture.

3. Filtration

   • Micron Filter removes sludge and particles larger than 1 micron.
   • Micron Filter captures finer contaminants up to 0.5 microns.

4. Degassing

   • Heated and filtered oil enters the degassing chamber, where it is showered for maximum surface exposure.
   • Vacuum conditions vaporize and remove dissolved water and gases.
   • Vaporized impurities are extracted by the rotary vacuum pump.

5. Recirculation and Output

   • Purified oil is recirculated or returned to the source via the outlet pump.

Testing & Quality Assurance

• The system is pressure-tested at 3 kg/cm² for pneumatic leaks.
• High vacuum leak rates are verified to ensure system integrity.
• Filtration performance is tested for achieving specified particle
