Hospital cryogenic tanks

اکسیژن بیمارستانی


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 using oxygen transport machines, oxygen liquid is charged inside the tank.

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 our 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.

اکسیژن ساز

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

• No need to charge
• No need to replace
• Low working pressure and low risks
• No need to carry
• Performance assurance up to 10 years

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

مخزن اکسیژن

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

• No need for repairs
• No need for periodic service
• Long service life
• No noise pollution
• No need for electricity
• Purity above 99%
• Low pressure and safe
• Continuous operation
• No need for roof storage
• No need to set up

• Requires monthly charging
• More initial capital than oxygen capsules

کپسول اکسیژن

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

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

• Need to change daily or weekly
• High charge cost
• High pressure and side hazards
• Many overhead people
• Uncertainty about being full or empty
• Replacing valves
• Perform periodic tests

سوالات متداول

اکسیژن مایع را از کجا تهیه کنیم؟

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.

قیمت هر کیلو اکسیژن مایع چقدر است؟

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 this amount is included in the on-site evacuation fee and does not include shipping costs separately.

فضای مورد نیاز مخزن چقدر است؟

The required area of 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.

محل نصب مخازن باید چه شرایطی داشته باشند؟

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)

آیا استفاده از اکسیژن مایع مشابه سیلندر اکسیژن، بیمارستان را به دیگر مراکز وابسته می کند؟

The choice of liquid oxygen tanks is based on recharging 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. Is.

هزینه حمل اکسیژن مایع چقدر است؟

Oxygen transportation costs are included in the price of oxygen, and the centers do not need to pay for shipping separately. Purity and weight should be clearly specified for the buyer.

تعمیرات و نگهداری مخازن کرایوژنیک به چه نحوی می باشد؟

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.

در چه مواردی مخزن اکسیژن مایع پیشنهاد نمی شود؟

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.

آیا مخزن نیاز به محیط مسقف دارد؟
آیا دمای هوا (گرم -سرد)در کارکرد تاثیر دارد؟

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.

آیا مخزن اکسیژن مایع نیاز به گواهی imed دارد؟

Since the beginning of 1398, the General Directorate of Medical Equipment has made the sale of tanks conditional on having an imed certificate.

ایمنی مخزن اکسیژن به چه صورت می باشد؟
آیا مخزن اکسیژن خطر انفجار دارد؟

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.

بجز هزینه مخزن چه هزینه های برای نصب این تجهیز باید انجام شود؟

1. The cost of buying a tank
2. Foundation cost (average 10 million)
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.
