The purity of the output is upto 99.7%, which is perfect for healthcare and industrial applications. The systems get acclaimed for a number of features such as advance technology, low power consumption, skid mounted technology, ease of installation and minimal maintenance.

DESCRIPTIONS : (Model DCPL 50m3/hr)

Oxygen plant model 50 m3/hr is designed and manufactured to generate compressed oxygen gas in cylinders with purity upto 99.7% and at standard 150 to 160 Bar (kg/cm2). The system produces high purity industrial and medical oxygen. The model dcpl 50 use liquid oxygen pump technology to fill liquid oxygen directly from the liquid in the condenser to fill compressed gaseous oxygen in cylinders at 155 bar( 200 bar optional).


SKID MOUNTED DESIGNS: Due to the design, all our equipments and machineries are mounted on single skid ready for installation.

AIR SEPARATION UNIT (COLUMN): The columns are made from cryogenic grade STAINLESS STEEL materials with argon welding in order to make them leak proof operation and to produce high quality medical and industrial oxygen .

LIQUID OXYGEN PUMP: Oil-free and water free design with special stainless steel head, the pump fills in compressed gaseous oxygen in cylinders.

MOLECULAR SIEVE BATTERY: We use special over-size design with L/D ratio to prevent fluidization and long life with molecular sieves of Zeochem, Switzerland/ceca france .

PURITY: 99.7 % High purity of Oxygen for medical and industrial uses.

PROCESS SKID: All equipments are mounted on processed skid complete with gas/air/ water lines for high purification of air.

TECHNOLOGY: Our technology is internationally approved for its exceptional performance, durability and usefulness.

Process Description:

STEP 1 - Air Compression

Atmospheric air is compressed at a low pressure of 5-7 bar (Gas plants) by our trouble free rotary compressor (Screw / Centrifugal Type advanced technology is employed in lieu of old bulky piston reciprocating compressor).

STEP 2 - Air Pre-Cooling

The second stage of the process uses a low pressure refrigerant (R-407A as per CE regulations) for pre-cooling the processed air to temperature around 12 deg c before it enters the purifier.

STEP 3 – Purification

The air enters a purifier consisting of twin Molecular Sieve driers working alternatively. The Molecular Sieves eradicate the CO2 & moisture from the process air before the air enters Air Separation Unit.

STEP 4 - Separation of Oxygen and Nitrogen at Air Separation Column

Oil free, moisture free and CO2 air enters into low pressure plate fin type Heat exchanger where the air is cooled below sub zero temperatures by air expansion process. Due to the excellent thermal efficiency, we can achieve a temperature difference delta t as low as 2 deg c at the warm end of these exchangers.

STEP 5 – storage for Gas

The final product in the form compressed Oxygen/Nitrogen goes to the high pressure oxygen cylinders at 150 bar or upto higher UPTO 200 BAR as required, or for pipeline supply or captive consumption.
