Product Description

We are manufacturing Industrial type Automatic Voltage Regulators (Stabilizers/Rectifiers) using the differential wound Vertical Roller Type Regulators. Manufacturing LINEAR TYPE +/- Heavy Duty Regulators with rollers rolling on both the sides of the coil. The size of conductor used is more than THREE TIMES than used in conventional design regulators. Being + type, the same winding is used for boosting the voltage on one side and bucking the voltage on the other side of the regulator. So, the rating of the regulator required is half of the conventional design regulator.

Special Features

Up to 80% reduction in failure rate of electrical equipment
Energy saving up to 10% (up to 30% on lighting load)
Reduction in MDI
Improvement in Power factor
Uniform quality of end products
Improves Productivity of the plant
Depreciation @ 40% as per Income Tax Act (In India) being an energy saving device.

Application

Mines & Collieries, Cement Plants, Flour Mills, Hotels & Restaurants, Food Processing units, Pharmaceutical Units, Cold Storages, Textile Mills, Plastic Moulding, Any kind of manufacturing.
