Air Cooled – Oil Cooled
Air Cooled (1 KVA to 75 KVA)
We are one of the leading manufacturers and supplier of Servo Stabilisers (micro processor based) that delivers constant voltage irrespective of input (EB) voltage. This comes with surge & spike suppressor, line conditioning technique. Our Servo stabilisers can be classified into Air Cooled Stabilisers and Oil Cooled Stabilisers. While an air cooled stabiliser is generally used for areas with power capacities less than 100 KVA. Oil cooled stabiliser can be used in industries where dust and flammable particles like cotton dust, foundry dust, etc., are very high, oil cooled stabilisers should be used even for lower capacities to prevent fire accidents and to attain trouble free
Oil Cooled (9 KVA to 500 KVA)
Applications of Servo Stabilisers:
The unending list includes: CNC machines, engineering industries, modern textile machineries, medical equipments, hotels & restaurants, multiplexes, malls & apartments, educational institutions, lighting loads, lifts & elevators, air conditioning equipments, factories, hospitals, IT companies & BPO’s, gymnasiums, photocopying centres (Xerox centres), DTP centres, Corporate buildings & offices, retail showrooms, restaurants, theatre projectors, etc.,
