SVS, Oil Cooled, 20 KVA
Oil-cooled SVS for heavy industrial loads, 20–500 KVA. Quiet, efficient, handles 200% momentary overload. Mounted on wheels for easy install.
Product Description
This 20 KVA stabilizer uses oil cooling, which dissipates heat more effectively under sustained load than air cooling does. It handles overloads up to 200% momentarily and keeps no-load losses under 0.8%, figures that matter when equipment runs around the clock.
It’s aimed at factories, large manufacturing plants and heavy machinery installations, where three-phase supply is often unbalanced and load can swing sharply through the day. The unit sits on wheels for easier positioning, includes earthing terminals, and is tested to IS:9815-94 for both routine and type testing.
For high-value industrial equipment, motors, CNC machines, large processing lines, this is the stabilizer built to keep running through demanding cycles without the losses and downtime that come from unstable voltage. It costs more upfront than the air-cooled alternative at the same capacity, but for continuous industrial use that’s usually the right trade.
Automatic Correction
Corrects voltage automatically and continuously, keeping supply stable at all times.
Motor Protection
Ensures induction motors operate at high efficiency by supplying constant voltage.
Equipment Protection
Protects costly equipment from High/Low voltage menace, cutting down maintenance costs.
Reduced Production Losses
Minimizes production losses and improves overall plant efficiency.
Increased Productivity
Stable voltage supply leads to increased productivity across operations.
Tax Benefit
Eligible for 100% depreciation as per Income Tax Act.
Lower MDI
Reduces Maximum Demand Indicator (MDI) and saves power.
Electricity Savings
Reduces electricity bills by up to approximately 15%, depending on input variation and working hours.
Diesel Savings
Saves on diesel cost, as generators need not run at High/Low input voltage.
Fast ROI
Average payback period of approximately 18 months owing to high energy-saving capability.
Recommended Applications
- Information Technology & Call Centers
- Computer and Micro-Processor Controlled Equipment
- Scientific, Medical, Agricultural & Educational Research Instruments
- Offset Printing Presses, Color Scanners, Phototypesetters & Photographic Equipment
- Medical Equipment — X-Ray Machines, ECG Machines/Monitors, MRI, CT Scans

Not Recommended For
- Small single-appliance loads like a single fan or light, where a plug-in voltage protector is more economical
- Applications requiring instantaneous (zero-time) correction, since servo stabilizers correct voltage gradually via a motorized mechanism
- Extremely space or weight-constrained installations, as servo units are bulkier than static/AVR types
- Environments with frequent, rapid voltage fluctuations occurring within milliseconds, where a static (electronic) stabilizer responds faster
- Portable or frequently relocated setups, since servo stabilizers are typically fixed installations
