Cryogenic refrigeration is refrigeration which uses freezing mixtures such as dry ice, soilid co2, liquid co2, or liquid nitrogen. In the liquid co2 or liquid nitrogen method, a compartment is fitted with a temperature sensing element that can be preset. This is in turn connected to a control panel which activates liquid co2 or liquid nitrogen cylinder fitted with regulators to release the refrigerant. This is delivered through a spray header into the compartment until the desired temperature is achieved.

What is the definition of cryogenic service?
In physics, cryogenics is the study of the production of very low temperature (below −150 °C, −238 °F or 123 K) and the behavior of materials at those temperatures.
What materials used for cryogenic application?
The only alloy steel recommended for cryogenic service is 9% nickel steel. It is satisfactory for service down to -195°C and is used for transport and storage of cryogenics because of its low cost and ease of fabrication. Other alloy steels are suitable for service in the low-temperature range. The steels A201 and T-1 can suffice to -45°C, nickel steels with 2.25% Ni can suffice to -59°C, and nickel steels with 3.5% Ni to -101°C.
What does cold as kraut mean?
Cold as Kraut is a similie and is comparing one thing to another. This particular similie means that you are as cold as a german. This is said because Kraut is what the English used to call Germans in world war two and it basically means that you are as cold hearted as a Nazi or a Kraut. As it was explained to me years ago by an elderly gentleman, "cold as Kraut" meant cold as saurkraut. Before the days of refrigeration, saurkraut was stored in large stone vats underground. And they got very very cold.
What is a hoopie?
Has Multiple MeaningsHoopie is a slang term used in the Upper Ohio River Valley in the Ohio, Pennsylvania, and West Virginia area. Originally used in the East Liverpool, Ohio area to refer to people from the hill areas of West Virginia who would bring saplings in to town to sell to coppers to make barrels, it is a derogatory term, much like hillbilly and hilljack, that is still in use today.Hoopie is also used to refer to vehicles. One use is for a straight truck used in the trucking industry to make deliveries, often to residences or where streets are narrow. The trucks sometimes have refrigeration units or lifts attached.A vehicle made from a car or truck chassis and having homemade seats is referred to as a hoopie in the rural parts of Northwestern Pennsylvania. Not street legal, they are used to travel on trails in the woods.African-Americans in Michigan sometimes refer to junky-looking cars as hoopies.
Where did the phrase like shooting fish in a barrel originate What does it mean?
It originated from when two men were having a shooting contest. They each said what each other had to shoot. Number 1 said to shoot a bird in a tree and Number 2 said to shoot a fish in a barrel- thinking that it would be very hard. Apparently- shooting fish in a barrel was incredibly easy! This was because the vibration of the water ,once it was shot ,was enough to kill the fish in it! EG: Doing a somersault is like shooting fish in a barrel. It means that something is very easy! While the above answer may be possible, it seems a bit unlikely to me. Prior to the days of refrigeration, fish were packed and stored in large barrels. The barrels were packed to the rim full of fish. As such, any shot the entered the barrel would be guaranteed to hit at least one of them. This being the case, nothing would be easier than shooting fish in a barrel.
What is cryogenic heat treatment?
cryogenic metal treatment
Is neon important?
yes because you need it for electron tubes, plasma studies, fluorescent starter tubes, gas lazors, and then comes cryogenic refrigeration. so yes its important (im the one who asked the questin in the first place).
What are the some example of cryogenic gases?
Any gas that liquifies below -150 degrees C is a cryogenic gas. The most popular cryogenic gas is liquid nitrogen.
What has the author D Faulmann written?

What medical use does the element neon have?
According to chemicool.com, the element neon is used for :It is often used in brightly lit advertising signs. Neon is also used in high-voltage warning indicators, in Geiger counters and in television tubes.Liquid neon is used as a cryogenic refrigerant.
What is cryogenic freezer?
A cryogenic freezer is used to bring components inside the freezer down to cryogenic temperatures. Many cryogenic freezers are available for all sorts of applications. Cold boxes with added ln2 capabilities can refrigerate parts and then complete cryogenic processing cycles. Additionally, cryo freezers are available to freeze sex cells, stems cells, and more. Sometimes people are frozen after death, which is called cryonics. I have added a site below that has cryogenic freezers and processors available.
What rhymes with photogenic?

Was some cryogenic frozen?
cryo-what!?
Is cryogenic freezing related to nitrogen?
Cryogenic freezing is certainly related to nitrogen. In order to complete a deep cryogenic treatment a cryogen must be used. The least expensive cryogen for deep freezing is liquid nitrogen. Another cryogen is helium which allows special made cryogenic processors to reach temperatures approaching absolute zero.
