Superior heat dissipation using transformer oil for continuous heavy load operation.
From 10kVA to 500kVA, customizable for industrial plants, hospitals, and infrastructure.
High precision servo motor for ±1% voltage regulation, protecting sensitive machinery.
Robust construction, overload protection, and 24x7 duty cycle for demanding environments.
An Oil Cooled Voltage Stabilizer is a heavy-duty automatic voltage regulation system designed for industrial and large commercial applications. It utilizes high-grade transformer oil for efficient heat dissipation, enabling continuous operation even under extreme load conditions. These stabilizers are ideal for environments with severe voltage fluctuations, offering robust protection for expensive machinery, motors, compressors, and entire production lines.
Unlike conventional air-cooled stabilizers, oil cooled units provide superior thermal management, longer operational life, and higher tolerance to overload. The servo motor controlled mechanism ensures precise voltage correction with an accuracy of ±1%, maintaining output voltage within safe limits. This prevents equipment damage, reduces downtime, and improves overall energy efficiency.
INDUS Oil Cooled Stabilizers are manufactured using high-grade copper windings, CRGO core, and premium insulating oil. They come with advanced protections including overload, short circuit, high/low voltage cutoff, and phase failure. Our solutions are trusted across industries such as steel plants, pharma, textile, healthcare, data centers, and infrastructure projects.
