Hospital cryogenic tanks

Oxygen for Hospitals

_

Oxygen is vital in all hospitals and this has led to the concentration of relevant people and managers in the hospital. The hospital liquid oxygen tank is a stationary equipment that works without the need for electricity and operators.

How these tanks work is that they are installed on the foundation in the hospital and they are refilled using the oxygen transportation vehicles.

By opening the valve, the current flows at the set pressure in the pipeline to the central panel and is transmitted to the consumer sections.

The only activity required at this time is a weekly check of the liquid gauge gauge, which indicates the percentage of fullness of the tank. If the gauge is between 20% and 30%, the next charge must be ordered.

The purity of oxygen will be constant in these conditions and according to the pressure regulator, there will be no pressure drop even at the highest consumption.
To learn more, here are three ways to use oxygen in a hospital.

Oxygenator

It is a versatile device that uses oxygen to separate oxygen from the air.

Advantages:
• No need to be charged
• No need to be replaced
• Low working pressure and low risks
• No need to be transferred
• Performance assurance up to 10 years

Disadvantages:
• Low purity percentage in cases of high use
• Pressure drop
• Expensive and long-term repairs
• Needs electricity
• Requires an operator
• Requires a storage room
• High initial cost compared to oxygen tanks and capsules
• Requires continuous service
• Noise pollution
• Replacement of zeolite in long term
• Indoor space required

Oxygen Tanks

Liquid oxygen tanks are state-of-the-art tanks that operate without the need for electricity and operators.

Advantages:
• No need for repairs
• No need for periodic services
• Long life-cycle
• No noise pollution
• No need for electricity
• Purity above 99%
• Low pressure and safe
• Continuous operation
• No need for roof storage
• No need to be set up

Disadvantages:
• Requires monthly charging
• More initial cost than oxygen capsules

Oxygen Capsules

It is one of the oldest methods that still responds well to the needs of hospitals.

Advantages:
• No need for electricity
• No need for repairs
• High purity
• No pressure drop
• Continuous operation
• Low initial cost

Disadvantages:
• Need to change daily or weekly
• High charge cost
• High pressure and potential risks
• No indicator to check whether the capsule is full or not
•Needs to be situated indoors
• spare part costs
• in need of periodical diagnosis

Frequent Asked Questions

_
Where can I supply Liquid Oxygen?

There are more than 120 liquid oxygen production plants in Iran that can supply the oxygen needed by the hospital.
In some small towns, these liquid oxygen generating plants may not be available, but this is not a cause for concern. Liquid oxygen transport machines are active throughout Iran and carry oxygen to the farthest corners of Iran.

How much is Liquid Oxygen per kilo?

Each kilo of liquid oxygen in Iran is priced at an average of $ 0.18 in metropolitan areas and $ 0.27 in remote centers.
It should be noted that on-site evacuation fees are included in the prices above and no extra fee for transportation is charged.

How much space does the Tank require?

The required space for the tank is about 4 * 4 meters, of which 2.5 meters in diameter is required for the tank and the rest is for access around the tank.
This space is for a tank with a capacity of 20 tons of oxygen.

What conditions should the place of installation have?

The location of the tank should be at a point that is accessible to the truck and stopping the truck for 1 hour at that location should not obstruct the route.
Preferably, the location of the tank should not be the location of oil and combustible material (a distance of 2 meters is sufficient)

Does usage of liquid oxygen make me dependent to other corporations?

The choice of liquid oxygen tanks is based on recharging it once a month or two. This is while the capsules have to be recharged weekly, so 10 recharges per year with more than 1000 oxygen transporters across the country is a very simple task.

What are the transit costs of Liquid Oxygen

Oxygen transportation costs are included in the price of oxygen, and the costumer does not need to pay for shipping separately. When delivery is due, a certificate of oxygen’s Purity and weight and also a scale sheet is given to the costumer so that the weight and purity is totally clear to the buyer.

How are cryogenic tanks repaired and maintained?

Oxygen tanks do not need to be maintained due to the fact that they are part of the fixed equipment and only their valves and regulators should be inspected annually. This is done without the need to stop operation and at a small cost. Experts say that because the tank is double-walled, they inspect the tank or the gap between the two walls, which is completely wrong.

In what cases is a liquid oxygen tank not recommended?

The oxygen tank is not recommended in the following cases:
1- Daily consumption of less than 3 capsules per day
2- Centers where it is not possible to install the tank due to space limitations.

Does the tank need a roofed environment?
Does air temperature (hot-cold) affect performance?

The temperature of liquid oxygen is (-183) degrees Celsius and naturally differs from the ambient temperature by about 200 degrees Celsius, so changing a few degrees of air does not affect the operation of the tank. For this reason, the tank does not need a roofed space.

Does the liquid oxygen tank need an imed certificate?

Since the beginning of 1398, the General Directorate of Medical Equipment has made the sale of tanks conditional on having an imed certificate and Pishrun Zamharir Aseman is the first company to aquire this certificate for producing liquid oxygen tanks.

How safe is the Oxygen cryogenic tank? Does it have a danger of explosion?

The word oxygen is associated with the risk of explosion in the public mind because of conventional cylinders, which can be dangerous due to high working pressure. In the tank but due to low working pressure, double wall, special safety equipment and testing There is no such thing as a risk.

Other than the cost of the Tank itself, what other costs are needed for the cryogenic tank to be installed?

1. The cost of buying a tank
2. Foundation cost
3. Execution of the pipeline
4- Heat exchanger (vaporizer) – This equipment is suitable for centers that consume more than 400 kg of oxygen per day.
