A Comparison Between Air Cooled Servo Stabilizer and Oil Cooled Servo Stabilizer

At times you have noticed that voltage fluctuates across a certain range. At that time it is very necessary to stabilize the voltage and also regulate it as well. This stabilizing is primarily done by a stabilizer. A stabilizer helps to keep a consistent distribution of voltage for all loads and appliances.

A Servo stabilizer is a device that stabilizes the input power by making use of a servo motor in order to give the most desired voltage supply. Thus it can be conveniently mentioned that a servo stabilizer is an electromechanical device that has the capability with the voltage regulating speed that is relatively slower than a static voltage stabilizer.

The role of a voltage stabilizer is to produce a consistent output of voltage ensuring the proper functioning of several electronic devices. A stabilizer also regulates the current fluctuations in a much better way so that it can provide proper utilization of power. Moreover, with a constant supply of current from a servo voltage stabilizer, it is also very advantageous for different types of electronic devices in industries, hospitals, hotels, lifts, CNC machines and etc.

The two types of servo voltage stabilizers that are used are as follows:

  • Oil-cooled Servo Voltage Stabilizers
  • Air-cooled Servo Voltage Stabilizers

Let us now look into the differences between Air Cooled Servo stabilizers and Oil Cooled Servo stabilizers.

Air-cooled Servo Voltage Stabilizers

An Air-cooled Servo Voltage Stabilizer is very much effective for different types of electronic and electrical applications. The servo stabilization system with air cooling refers that it smartly ensures optimum voltages. 

Air-cooled Servo Voltage Stabilizers are made up of a transformer with a power control circuit which is used for controlling the output of Alternating Current voltage. The negative feedback circuits help in controlling the power or voltage automatically. It also regulates to a certain range that is required or previously set. The productive part of an Air-cooled Servo Voltage Stabilizers is that in complete functioning, the voltage regulator does not need any sort of manual involvement or interruption. The entire functionality is done automatically.

Oil-cooled Servo Voltage Stabilizers

In an Oil-cooled Servo Voltage Stabilizer transformer oil is poured inside the vessel where the transformers are installed. The transformers thus are in direct connection with oil. This oil hence acts as a cooling agent. It reduces the heat from all the heated transformer windings. In an Oil-cooled Servo Voltage Stabilizer oil freely flows through the cooling radiators or fins. This process normalizes the temperature. The bodyweight of the transformer and the weight of the transformer oil both put up with the entire weight of the stabilizer. Where voltage range is in higher variations with higher capacity this type of stabilizer is preferred the most. Also where air ventilation is not in proper order or there is much less space there also Oil-cooled Servo Voltage Stabilizers are preferred to a great extent. Also, there are some special situations where Oil-cooled Servo Voltage stabilizers can be kept in open space without any type of shades being provided just like the transformers.

Difference between Air Cooled Servo Stabilizer and Oil Cooled Servo Stabilizer

 The distinctive difference between an Air-cooled Servo Voltage Stabilizer and Oil-cooled Servo Voltage Stabilizer is that the capacity of the Oil-cooled Servo Voltage Stabilizer is of higher capacity. Also, an Oil-cooled Servo Voltage Stabilizer is the most suitable one for places where the voltage fluctuation frequency is in a higher range. In the case of an Oil-cooled Servo Voltage Stabilizer, it provides a safe guarantee that the voltage fluctuation in current will not affect any of the electrical types of equipment or any electrical appliances.

In Conclusion

Based on the application the Air Cooled Servo Stabilizer and Oil Cooled Servo Stabilizer have different implementations. Both of the Stabilizer types are important in their own area of work. 

For example, air-cooled servo voltage stabilizers are used in CNC machines, Printing Machines, Telecom & Data Centers, Machines with Sensitive Microprocessors, Textile Machines, Medical Equipment, and much more alike. Evidently, Air Cooled Servo Stabilizer is good in scenarios where there are provisions of good airflow like factories or workshops.

Whereas oil-cooled servo stabilizers are used in Automobiles, Engineering & Machine Tools, Lift & Elevators, CNC Machines, and Plastic Machines. Evidently, oil-cooled servo stabilizers are used in scenarios where there is an enclosed area.

It is needless to say Air Cooled Servo Stabilizer and Oil Cooled Servo Stabilizer are very effective in their own way and are to be used as per the need.
