Duer

What is Doer and what is its use? In the following, after providing important information about this product, we intend to discuss its most important uses. To get more information about dewars, stay with us until the end of this article. Also, if you want to buy this product or get advice for getting more information about this product, you can contact our colleagues at landline number 021-79261000 or mobile number 09105929219 Please get in touch.

Doer are actually containers that can be used as insulation. These products are used to store gas condensate. which usually have less pressure and volume. Currently, their use has become very prosperous and we see different types of products in the market. We can benefit from the applications of these products to store cryogenic liquids. Doers consist of two types of flasks that are placed inside each other. Also, the space between these two flasks is empty. In fact, the space between them has created special conditions that we can use to store different liquids. The main and most important use and purpose of them is to prevent the transfer of liquids. It is necessary for decker that the inner flask is insulated and when liquids are placed inside it, its heat is not transferred to the outside.

Doer purchase

If you intend to buy Doer or need more guidance and advice to buy this product at the best price from the largest and most advanced manufacturer of Doer in Iran, namely Pishran Zamhrir Asman Company, our colleagues call us at our landline number 021-79261000 or mobile number 09105929219 are ready to provide service and advice to you to prepare this product.

Duer applications

What are the uses of Doer? This product is mostly used in research laboratories. To store liquid gases, we need to put them in gas flasks. For example, after buying liquid nitrogen to store it, we can benefit from the advantages of this product. Doers are usually produced in different sizes and volumes from 2 to 50 liters. The material of their body is usually aluminum and they are insulated in two layers. Also, another reason for using this product is to prevent the heat from escaping and the cold from entering, which the consumer of this type of product can confidently use it Also, these products have a very low working pressure and this issue has increased their efficiency.

One of the most important uses of heat exchangers in these tanks is that they are designed in such a way that they convert liquid into gas. It goes without saying that gas flasks can be used in different pressures. The pressure provided by this type of products is between 2 and 26 bar. Also, some manufacturing companies design this type of products in two or three layers. so that they can improve their efficiency and prevent heat transfer. Also, some manufacturers paint the outer surface of this product with silver to increase their efficiency. This causes the heat to be reflected.

Important points regarding Duer

– Their working pressure is from 0 to 29 bar according to the customer’s order.
– Reducing the risks of unloading and loading the cylinder

History of Duer

Doer has the ability to store cryogenic liquids for more than 24 hours. This product was created by James Doerr after extensive cryogenic research. In order to invent this product, he had a special activity on liquefied gases for more than ten years. In the past, it was very difficult to keep gases at certain temperatures that turned into liquids. Therefore, James was looking for a solution to increase the storage time of this type of gas, and this led to Doerr’s invention.

In 1872, James along with Peter produced this gas vacuum flask to keep his desired materials at the desired temperature. The most important feature of this type of flask was having a narrow neck. Later, new models produced by the company had a narrower neck and a silver finish. This greatly increased their efficiency to prevent heat loss.

Doer production

With the advancement of technology day by day, we see different types of these products that are produced by different companies. Glass is used to make this product. Internal and external lamps are also used above the neck opening. The vacuum insulation between these two flasks can prevent heat transfer. This heat transfer happens neither inside the container nor outside. In fact, in this system, there is no energy exchange between the system and the world, nor does heat transfer occur inside the system. For this reason, the system is completely isolated.
