What is CE certification ?

CE certification symbolizes mark of quality meaning a certified company can sell its products and services in the USA and European market. The certificate holding companies bear all quality norms necessary for the international market. The CE marking is considered as the manufacturer's declaration that the products and services meet the requirements of the applicable EC directives.


Step – 1: Compression of Atmospheric Air By Air Compressor

Our Latest Air Compressor of Atlas Copco is employed to compress air at 5-7 Bar. The screw/centifrigal type advanced technology is employed in the compressor replacing old bulky piston compressor. The Atlas Copco compressor reaches to our customers after passing through the detailed testing and check to ensure optimal performance for all installations. The component is air cooled and oil free meaning it neither requires water nor oil.

Step – 2: Pre Cooling System

The second stage of the process uses a low pressure refrigerant for pre-cooling system to process the air to temperature around 12 0C before it reaches into the purifier.

Step – 3: Purification of Air by Purifier

In this step, the air allows to pass through a number of stages to remove the impurities available for instance dust, hydrocarbons and Carbon Dioxide. Our latest molecular sieve from Zeochem of Switzerland is very effectual to remove CO2.

Step – 4: Separation of Liquid Air into Oxygen and Nitrogen in Air Separation Column

After getting the air free from oil, moisture and carbon dioxide, it enters into low pressure plate fin type Heat exchanger where the air gets cooled below sub zero temperatures by air expansion process in the cryogenic expander. The cryogenic expander cools the air to temperature almost below -165 to-170 deg C. Air gets liquefied when it enters the air separation column & gets separated into oxygen & nitrogen by the process of rectification. The liquid oxygen and liquid nitrogen comes up a purity of 99.7% and 99.99% respectively.

Step – 5: Product storage

The liquid oxygen/nitrogen can be filled in cryogenic liquid tanks. It is advised to equip power insulation cryogenic storage tank. Available in different capacities, the election of storage tank is subject to the requirement of the customer.


Air Compressor

Our air compressors are from Atlas Copco, a US based company. The oil-free compressors promise energy savings. The component uses oil-free air technology ensuring leaks and energy waste are minimized. It is also of air cooled design meaning it does not require water to cool down. Its oil-free air technology and air cooled design help you safeguard the environment and better comply with international regulations.

Pre-Cooler System

Our company acquires the pre-cooler system from world fame brands in order to ensure smooth functioning of our machines. The main function of the system is to cool down the compressed air to 5 to 8 Degree Celsius and discharge the condensed water. The component is technologically very advanced.
