3. Objective of this presentation…
Production of Medical Grade Oxygen through
Pressure Swing Adsorption (PSA) techology
Oxygen produced on Demand
Oxygen for Modern Hospitals
To highlight the benefits of producing your own
medical oxygen

4. Why PSA technology – Medical Oxygen
• Economical and cost effective method of Generating
Medical Oxygen.
• Safe and flexible options of Installation Site.
• Oxygen is generated at required Pressure. No High Pressure
equipment.
• Manpower Independent and least dependent on third
party agency.
• No Approval or Certification required from any Agencies.
• Time tested and proven technology.
• Ease of Maintenance , operation and handling.
• Fully Automatic – Produce as much you need.

6. Purity recommended
by Authorities
US/Indian/European – Pharmacopeia declares
both as “Drug”
93% oxygen from PSA technology
(molecular sieves)
(or)
99% from Cryogenic

7. Liquid Oxygen (LMO)
• Requires Large and accessible area for Installation with clear distance
from the Hospital building.
• NOC required from Chief Controller of Explosives, Nagpur
• Monthly rental (or) fluctuation in prices, year after year.
• Evaporation losses up to 15% due to temperature and Pressure variations.
• DEPENDENCE ON 3RD PARTY SOURCE FOR MEDICAL OXYGEN .
• External factors like Strikes and Permit restriction could effect the supply
of Liquid Oxygen
• Accessibility issues for filling the Oxygen Tank.

8. Large Space wasted…….
for
Liquid Oxygen installation

9. Oxygen Storage Tanks – To be handled carefully – Explosive in nature

10. Oxygen in Cylinders..
• 3rd party dependent, Erratic supplies
• Expensive, prices keep increasing
• Residual gas wastage – pilferage.
• Noise and handling issues with cylinders in the
Hospital.
• Manpower dependent for Manifold management
stock maintenance and billing matters.
• Improper filling of cylinders from small vendors.

11. Cylinder manifold…

12. Oxygen in a cylinder is filled at very high
pressure and also dangerous………sometimes

13. Oxygen Generating system
with back up of cylinders

14. Oxygen Generator (Dual system) with
Cylinder filling facility as option

15. Oxygen Generators……..Are they viable ???
Refilling cost of oxygen……………
• In cylinders ranges from Rs.150 to Rs. 450
depending on the place and consumption (which
is approx. Rs.21/- to Rs. 63/- per cubic meter
• In Liquid form it ranges from Rs. 15/- to Rs. 23/- per
cubic meter
But Oxygen Generator, the cost is less and not more
than Rs. 8-12/- per cubic meter

16. Oxygen Generators………Service
Like any other high value medical equipment,
Oxygen Generators need proper maintenance &
service.
Cistron with their 23 yrs of experience have highly
qualified and trained engineers to take care of all
services.
Keyser Air Compressors used in Cistron Oxygen
Generating Systems have well trained Engineers in
all over the country.

17. Cost comparison….Cylinder &
Liquid Oxygen
COST ANALYSIS…………for e.g.
Hospital consumes 2 cylinders per hour (or) 14.2
cub.meters per hour Liquid Oxygen
Refilling Cost:
1) Per cylinder…..Rs. 175/-
2) Liquid Oxygen…..per cub. Meter…….Rs. 16/-
If cylinder, then, it is 24x2x175 = Rs. 8400/- per day
If Liquid oxygen, it is 14.2x24x16 = Rs. 5452/- per day

18. Cistron Oxygen Generator – Same
consumption……Operating cost
Cistron Oxygen Generator……..OG 500
(capacity 14.2 cub. Meter per hour production)
• Keyser Compressor and Dryer…Power Rating….16 KW
• Power consumption in 24 hrs…..16x24 = 384 units
• Power bill……(@ Rs. 8/- per unit)…….384 x 8 = Rs. 3072.00
(the above is for a day)
• Maintenance cost per day……..Rs. 450.00
(from 2nd year onwards)
OPERATING COST of Oxygen Generator in a day will be 3072+450 = Rs.3522.00
OPERATING COST in a month………Rs. 108,000.00
WHAT IS THE SAVING THEN ???????????????????????

19. Savings
If cylinder, then, it is 24x2x175 = Rs. 8400/- per day
If Liquid oxygen, it is 14.2x24x16 = Rs. 5452/- per day
Oxygen Generator…..Cost per day……Rs. 3522/- per day
Cylinder Vs Oxygen Generator………savings
8400 – 3522 = Rs. 4878.00 per day and Rs. 17.80 lacs in one year
Liquid oxygen Vs Oxygen Generator………..savings
5452 – 3522 = Rs. 1930.00 per day and Rs. 7.00 lacs in one year

20. How is the saving if the
consumption is very high !!!!!!
COST ANALYSIS…………for e.g.
Hospital consumes 4 cylinders per hour (or) 28.4
cub.meters per hour Liquid Oxygen
Refilling Cost:
1) Per cylinder…..Rs. 150/-
2) Liquid Oxygen…..per cub. Meter…….Rs. 15/-
If cylinder, then, it is 24x4x150 = Rs. 14400/- per day
If Liquid oxygen, it is 28.4x24x15 = Rs. 10224/- per day

21. Cistron Oxygen Generator – Same
consumption……Operating cost
Cistron Oxygen Generator……..OG 1000
(capacity 28.3 cub. Meter per hour production)
• Keyser Compressor and Dryer…Power Rating….31 KW
• Power consumption in 24 hrs…..31x24 = 744 units
• Power bill……(@ Rs. 8/- per unit)…….744 x 8 = Rs. 5952.00
(the above is for a day)
• Maintenance cost per day……..Rs. 950.00
(from 2nd year onwards)
OPERATING COST of Oxygen Generator in a day will be 5952+950 = Rs.6902.00
OPERATING COST in a month………Rs. 210,000.00
WHAT IS THE SAVING THEN ???????????????????????

22. Savings
If cylinder, then, it is 24x4x150 = Rs. 14400/- per day
If Liquid oxygen, it is 28.4x24x15 = Rs. 10244/- per day
Oxygen Generator…..Cost per day……Rs. 6902/- per day
Cylinder Vs Oxygen Generator………savings
14400 – 6902 = Rs. 7498.00 per day and Rs. 27.00 lacs in one year
Liquid oxygen Vs Oxygen Generator………..savings
10244 – 6902 = Rs. 3342.00 per day and Rs. 12.00 lacs in one year

23. How is the saving if the
consumption is less………
COST ANALYSIS…………for e.g.
Hospital consumes 0.5 cylinders per hour (or) 3.5 cub.meters per hour
Refilling Cost:
1) Per cylinder…..Rs. 250/-
2) Per cylinder……Rs. 300/-
At Rs. 250/- per cylinder cost per day it is (12 x 250) = Rs. 3000 per day
At Rs. 300/- per cylinder cost per day it is (12 x 300) = Rs. 3600 per day

24. Cistron Oxygen Generator – Same
consumption……Operating cost
Cistron Oxygen Generator……..OG 175
(capacity 5.0 cub. Meter per hour production)
• Keyser Compressor and Dryer…Power Rating….8 KW
• Power consumption in 24 hrs…..8x24 = 192 units
• Power bill……(@ Rs. 8/- per unit)…….192 x 8 = Rs. 1536.00
(the above is for a day)
• Maintenance cost per day……..Rs. 325.00
(from 2nd year onwards)
OPERATING COST of Oxygen Generator in a day will be 1536+325 = Rs.1861.00
OPERATING COST in a month………Rs. 56605.00
WHAT IS THE SAVING THEN ???????????????????????

25. Savings
If cylinder refilling cost is Rs. 250/- then it is, Rs. 3000/- per day
If cylinder refilling cost is Rs. 300/- then it is, Rs. 3600/- per day
Oxygen Generator…..Cost per day……Rs. 1861/- per day
Both cases, the savings are as follows:
Filling cost of cylinder (Rs.250)…
Savings…(3000-1861) = Rs.1139.00 per day & Rs. 4.15 lacs a year
Filling cost of cylinder (Rs.300)….
Savings…(3600-1861) = Rs. 1739.00 per day & Rs. 6.35 lacs a year

26. CONCLUSION…..
Cistron Oxygen Generators are:
• Safe, reliable and easy to operate
• Occupy less space, can be installed in terrace
also
• No need of any permission or certification
• OXYGEN produced ON DEMAND
• Savings for any hospital
