Ambient Vaporizer

Let's Uncover Ambient Vaporizer

Ambient Vaporizer is made of extruded aluminum-finned profile tubes that interconnect with each other to vaporize the extremely cold liquids of around or below - 150℃ into its gaseous state for the users such as LO2, LN2 ,LAR & LNG. The gas is nearly warmed up to a temperature similar to the ambient air by absorbing heat from the surrounding environment.

How does the Ambient Vaporizer Function ?

The ambient vaporizer functions by utilizing the heat energy present in the surrounding ambient air to vaporize a liquid or liquefied gas. It consists of a heat exchange system with finned tubes or plates that increase the surface area for heat transfer. The liquid or liquefied gas is circulated through the vaporization chamber, where it comes into contact with the heat exchange system.

The ambient air flowing over the heat exchange surfaces transfers its heat energy to the vaporization chamber, causing the liquid or liquefied gas to heat up and vaporize. The resulting vapor or gas is then collected and directed to the desired application or storage system. Ambient vaporizers offer a cost-effective and energy-efficient solution for vaporizing liquids or liquefied gases without the need for additional external heat sources.

Industrial Gas Ambient Vaporizer Refers to

• The Liquid Oxygen Ambient Vaporizer is used to convert liquified oxygen, whose boiling temperature is -182.96 °C, back to its gaseous state. As for oxygen, it is widely known that it has a wide range of applications in our daily lives and industries, such as in medical settings, steel mills, and even space exploration. Through the process of vaporization, no external energy is required, making it environmentally friendly.

• The Liquid Argon Ambient Vaporizer is for warming up the inert liquid argon gas extracted from the air in a cryogenic air separation unit (ASU), which is at a very low temperature of -189.2℃, until it reaches a gaseous state similar to the ambient air temperature. Argon has a wide range of application in various fields, and argon arc welding is the most accknowledged one. It is a commonly used metal welding method where argon gas is used as an inert shielding gas, and a high temperature is generated on the workpiece through an electric arc to melt the metal and form a weld joint. This welding technique is often employed for high-quality and high-precision welding requirements, particularly for non-ferrous metals such as stainless steel, aluminum, and copper.

• Liquid Nitrogen Ambient Vaporizer takes in heat through the aluminum fins from the air to turn liquid nitrogen (LN2) of -196℃ to the state of gas without consuming any man-made power. Nitrogen is noble gas but widely used in our daily life and industrial productions like manufacturing, healthcare, food preservation, electronics, and aerospace. It helps prevent oxidation, maintain product quality, and ensure safety. Nitrogen plays a vital role in various sectors, contributing to advancements and improving daily life.

Design & Manufacturing

Zoiun Fluid & Gas's ambient vaporizers are designed with various finned tubing arrangements in different shape, size, pressure requets to meet customers' work conditions on-site, such as cryogenic tank pressurization, regasification stations, gas filling, dry nitrogen purging, and more.

• Material: Alumium / Stainless Steel
• Connection: NPT / FNPT / Flange
• Oxygen Application: Degreasing / Oil-cleaning

• Quality Relatives: The utilization of premium materials, implementation of diverse designs of finned tubing, and arrangement of convection spaces ensure the efficiency of equipment vaporization, preventing issues such as reduced vaporization rates and pressure drops. Furthermore, it prevents more severe situations like ambient vaporizer structural stress fractures or even collapse caused by inaccurate ambient vaporizer design calculations of flow velocity, gas volume, and excessive local frosting leading to excessive structural stress. Additionally, our vaporizer production strictly adheres to national pressure vessel design and manufacturing standards, as well as the relevant requirements of the international standard ASME.

• Pressure Range: Tube materials define the pressure of a vaporizer, alminum tubing holds the range of 0-35 bar (around 600psi), but high pressure ambient air vaporizers with different specified stainless tubed are used for 35-600bar (600-10000psi) application

Selection of Ambient Vaporizers

To select a vaporizer that exchanges heat from ambient air, there are several factors that you must primarily take into account.

• The Fluid: It is essential to have a thorough understanding of the physical and chemical properties of the liquid being vaporized by your vaporizer. For instance, you need to determine if the temperature of the liquid is lower than the vaporizer's design temperature, as this could potentially cause material quenching and result in equipment fracture. Furthermore, it is important to assess whether the liquid exhibits corrosive properties that could corrode the vaporizer's pipes, making it unsuitable for use. Moreover, it is crucial to identify if certain liquids cannot be vaporized beyond a specific pressure, such as carbon dioxide.

• Vaporization Capacity: Vaporization capacity is a crucial factor that must be carefully considered when selecting a vaporizer. It not only relates to the ambient vaporizer design but also impacts ambient vaporizer sizing customization to fit the production requirements and the available area on-stie. Moreover, incorrect vaporization capacity can lead to two scenarios. Firstly, when the vaporization capacity of the vaporizer exceeds the actual vaporization requirement of production, it can result in whistling noises and even resonate with the vibrations from the operation of cryogenic reciprocating pumps, thereby affecting the equipment's lifespan and causing noise pollution. Secondly, if the vaporization capacity is lower than the actual vaporization requirement, it can lead to premature frosting of the equipment, reducing vaporization efficiency and shortening its normal operating time. Additionally, the vaporized gas may not achieve the desired temperature, posing a safety threat to downstream equipment due to excessively low gas temperatures.

• Compliance and Standards: Zoiun Fluid & Gas is a ambient vaporizer manufacturer who build its equipments complying with relevant industry standards and regulations, such as ASME (American Society of Mechanical Engineers) codes and national pressure vessel codes.
