Compressed air produced by a Compressor is hot, dirty & humid and cannot be used in this state by pneumatic devices or other uses like producing nitrogen / oxygen, powder coating, pneumatic conveying, sand / shot blasting, micronizing, etc.

Our Compressed Air System is a ready-to-use package producing oil & moisture-free compressed air to the purity level required by the end-use. Standard Systems at 7 bar working pressure will give air quality of ISO-8573-1, Class 3:3:2. (Particulates < 5, Moisture PDP of - 20 C & Oil < 0.1mg/M) If the end-use moisture content is not stringent (Moisture PDP of +3 C, is acceptable), a Refrigeration Air Dryer will be provided instead of Heatless Air Dryer.

Lower levels of contaminants can be provided if required. Systems of higher pressure can also be provided.

Compressed air coming from the Receiver containing solid, liquid & vapour contaminants enters the Dryer through the Pre-filter (where solid & liquid contaminants are removed). It then passes through Oil Removal Filter and enters into Adsorption Tower A1 through a 3-way valve (CV-1) where it gets dried and then passes out of the Dryer through the After-filter. A part of this dry air passes through Tower A2 through the Purge Control Valve, where it picks up the moisture from the adsorbent thereby regenerating it and making it ready for the adsorption cycle. The purge air exhausts out of the Dryer through Purge Exhaust Valve (CV-2) of Tower A2.

After a fixed time, the functions of Towers A1 & A2 have to be reversed but doing this when the towers are at unequal pressures (Tower A1 is at line pressure & Tower A2 is at atmospheric pressure) will result in : adsorbent being subject to pressure shock and also starvation of air at outlet till Tower A2 attains line pressure in Tower A2. To avoid this, CV-2 is closed before the change-over and pressure in Tower A2 slowly rises to line pressure. The change-over is then effected by operating CV-1 and opening Purge Exhaust Valve CV-3 of Tower A1. The Adsorption Towers are now fully reversed, with Tower A2 under adsorption and Tower A1 under regeneration. At the end of this cycle, the tower functions will again be reversed. This cyclic operation is done through a Sequence Timer and the Dryer runs automatically.

Draining of Compressed air equipment such as Air Receivers, Moisture Separators, Filters, etc. is commonly done by low cost, timer - operated Auto Drain Valves. While these are effective in their functioning, they will open at the set time whether there is any condensate to be drained or not. This will result in loss of compressed air (and hence loss of energy), when there is no condensate to be drained.

The 'LEVEL SENSING Auto Drain Valve operation is level - based without any timer. The ADV has a Reservoir (in which condensate accumulates) connected to a drain valve which opens when condensate level reaches the top and closes when condensate level reaches the bottom. These operations are carried out by sensors placed at different levels of the reservoir. By this method only condensate is drained when the ADV opens and there is no loss of compressed air, resulting in saving of energy.

The reservoir & valve sizes are matched with the size and type , equipment to be drained, so that the ADV does not operate too frequently. Isolation valve & strainer are provided along with the ADV, for easy cleaning & servicing.

We offer gas generation system. Compressed air, nitrogen & oxygen are important utility gases in all types of industries. The compressed air system is installed in virtually all facilities, while the other gases are purchased.

Hot compressed air coming from Air Compressor cannot be used directly in most applications. It is therefore cooled to a temp of around 40o C, which is done in the Aftercooler

This is a shell & tube type Heat Exchanger where compressed air in the shell is cooled by plant cooling water circulating in the. tubes. The liquids which condensed due to cooling are separated by the in- built Moisture Separator. Draining can be done manually or by Auto Drain Valve.

The Ozone Generation System has an Air Compressor which provides the compressed air to the PSA Oxygen Generator Module where O2 is produced and then stored in the Oxygen Vessel. This O2 gas is subjected to a high voltage, AC electric corona (similar to lightning) in the Ozonator Module, where the molecular oxygen breaks down to atomic oxygen. Some of the atoms of oxygen thus liberated re-form into ozone, while others recombine to form oxygen. The resultant product gas containing ozone is in the circulating water in the Ozone Injection System. The Ozonated water is then used for required application. In some other applications ozone is injected directly in the water or air, as required.
