Using an oxygen generator is cost-effective or not

March 30, 2022

Oxygen generators are utilized in a range of business and industrial manufacturing applications today. These devices are critical in producing the required volumes of oxygen gas to power various operations.

PSA oxygen generators are commonly used for the subsequent purposes:

• Plants for sewage and wastewater treatment

• Manufacturing of glass

• Industry of Food and Beverage

• Papermaking

• Metallurgy

• Processes of chemical oxidation

• Fish aquaculture for profit

• Gasification methods in mining

The ability of adsorbent zeolite material to separate a stream of compressed gas into its component gases is employed in an oxygen generator employing PSA technology. Pressure swing adsorption could be a two-stage cycle that comprises simultaneous adsorption and desorption activities in two generating towers to make top quality oxygen.


An adsorptive tower full of molecular zeolite pellets selectively holds nitrogen while allowing oxygen to enter into a collecting tank as product gas harassed during the adsorption step of oxygen generation.

This selective adsorption process will continue until the adsorptive tower approaches saturation, at which point the zeolite sieve can not absorb any further nitrogen gas.


This is essentially a reversal of the adsorption of the PSA oxygen production process. The function of a tower within the adsorptive phase is altered because it reaches saturation. By rapidly depressurizing the cylinder and releasing absorbed nitrogen gas into the environment, the zeolite material is regenerated.

Hospitals all round the world are discovering that having a medical oxygen generator on site could be a highly reliable and cost-effective solution. The answer for his or her oxygen needs for his or her patients is an onsite oxygen plant. It saves your hospital money by eliminating the prices of obtaining, receiving, and monitoring oxygen supplies. Daily refilling costs money, as do injuries from manual handling and therefore the cost of cylinder stocking. liquefied petroleum gas supply may be quite expensive if the oxygen supplier is during a faraway area. If the operator doesn't take attention, hospitals can run out of medical oxygen cylinders.

A central regulation device detects oxygen and nitrogen gas saturation levels in both the adsorption and desorption towers, automating the complete PSA process. The action is accomplished by opening or closing the relevant process valves, likewise as increasing or decreasing the pressure within the zeolite filled cylinders.

Due to an oversized increase of Covid Cases requiring oxygen therapy, hospitals throughout India have experienced significant oxygen shortages in recent months. Hospitals are showing an increased interest in investing in an Oxygen Generator Plant to produce a standardized supply of life-saving oxygen at an inexpensive cost.

The technology behind oxygen generators isn't new. it's been available for over twenty years on the market.

What is the source of those newfound passions in Aquaculture?

There are two primary reasons for this:

1. We've never seen such extreme price volatility in oxygen cylinders, or worse... a shortage / crisis / lack of supply of cylinders to the purpose where dozens of patients died in ICUs gasping for air. Nobody wants something like this to happen again.

2. Small and midsize hospitals might not have the financial capacity to speculate so substantially in generators up front. they'd rather maintain it as a variable cost that they might depart this world to patients.

However, the govt. is now encouraging hospitals to put in captive oxygen generator units by bolstering its Emergency Credit Line Guarantee Scheme (with one hundred pc guarantee)

The expense of a Medical Oxygen Generator up front

Oxygen Generators are available in capacities starting from 10Nm3 to 200Nm3. This equates to about 30-700 (Type D cylinders (46.7litres) on a daily basis. betting on the capacity required, the investment in these Oxygen Generators could range from Rs 40 to Rs 350 lakhs (plus taxes).

Medical Oxygen Generator Operating Costs

The cost of running an oxygen generator is primarily made from two components:

• Charges for electricity

• Cost of Annual Maintenance

For information on electricity consumption, consult the manufacturer's technical specifications. A Comprehensive Maintenance Contract (CMC) could cost around 10% of the equipment's cost.

Medical Oxygen Generator - Yearly Savings & Payback Period

Oxygen Generators provide a high Return on Investment (ROI). Within a year, the whole investment may be recouped if the capacity is fully utilised. Even at 50% capacity utilisation or less, the value of investment is recouped in around two years.

The whole budget items may well be 1/3rd of what it'd be if cylinders were used, leading to a 60-65% reduction in operating costs. This is often a big discount.

About Medkav's technology

The greatest demand in every industry sector is for the most up-to-date, efficient, and improved technologies. This is today's requirement in order to secure our future. Creating a technological advancement is a great achievement. Making a breakthrough in this area will help it break into the industry for real-world use. Fitting oneself into the sea of expectations is not easy, but it is not impossible.

 Our mission is to help you get the most out of your industrial output while staying on budget. Cutting-edge oxygen generators are among our products and services, and they are suited for a wide range of business and industrial applications. By replacing oxygen cylinders with long-lasting, high-quality oxygen generators, we help hospitals save money.

All systems are built to run unattended and adjust the oxygen requirement automatically. The compact size of the plant is due to the design and instrumentation, as well as the assembly on skids and prefabrication from the factory. To achieve the desired Oxygen purity, the start-up time is only 5 minutes. As a result, these units can be turned on and off as the demand for oxygen varies. Continuous and steady operation with consistent oxygen purity is very dependable. Plant availability is always greater than 99percent. The expected life of the molecular sieves is roughly ten years, or the whole life of the oxygen plant. As a result, there are no replacement costs. You can give oxygen with the exact purity you want by changing the flow.

By replacing dangerously low oxygen cylinder supply with oxygen generator equipment, we helped India combat the devastating second wave of CoVID-19 in India.
