Excellentia-its Technology Partner with DRDO (Defence Research and Development Organisation ​)

Cabins and containers are easily transportable by truck and are available in “maritime" version.

​

 Excellentia DRDO Technology which is an offshoot of the On Board Oxygen Generation System (OBOGS) project for medical grade oxygen generation on board Tejas, fighter aircraft. It utilises Pressure Swing Adsorption (PSA) technique and molecular sieve technology to generate oxygen directly from atmospheric air.

​

This oxygen plant will be useful to provide oxygen supply during corona pandemic in hospital in urban and rural areas. The installation of medical oxygen gas plant helps in avoiding hospital dependency of scarce oxygen cylinders especially at high altitude and inaccessible remote areas. Benefits include reduced logistics of transporting cylinders to these areas, low cost, continuous and reliable oxygen supply available round the clock.

​

• High Reliability, full independency and automation

• Reduced Logistics, low cost, minimum maintenance

• Absolutely Oil free and safe

• 24/7-365 days operation, Onsite production of oxygen instantaneously from ambient air

• Electric Oxygen compressor to charge the cylinders upto 200 bar(g)

• High Performance molecular sieve (Li-LSX: Lithium based Low Silca X-Type zeolite)

• Stored oxygen supply for transient power failures

• Compliance with European/Indian Pharmacopeia and ISO 1008

• Low Energy consumption

• Frame Built, Skid Mounted design

• High Quality Touch screen control unit and remote control access
  
  Brief Specification of MOP

• Product Oxygen Concentration : 93±3 %

• Outlet Pressure : 4-6 bar ‘g’

• Capacity : 18 NM3/hr (300 LPM)

• Oil Content : ≤ 0.1 ppm

• Dew Point : < -50 ˚C

• Oxygen Compressor to charge oxygen cylinders of 47 litre water capacity at the rate of 20 cylinders per 8 hours.

​

Patient Handling Capacity - The Oxygen plant is designed for a capacity of 18 NM3/hr. The system caters for 60 patients at a flow rate of 5 LPM and can charge 60 cylinders per day as per the calculation given below. The capacity can be varied as per hospital requirement, if required.

• No. of persons =300/5=60
   

Cylinder Charging Capacity

• The oxygen capacity depends on the pressure of filling, which is about 150-200bar.

• Capacity of standard jumbo cylinder = 47 litres

• Cylinder pressure = 150 bar

• Volumetric capacity of cylinder = 150×47=7,050 litres (at NTP)

• Oxygen capacity of plant for 24 hours = 18000×24 = 4, 32, 000 (at NTP)

• No. of cylinders that can be charged in 24 hours= 432000/7050≅60
