Industrial Ambient Vaporizer Supplier
DSW provides cryogenic applications with direct steam heated vaporizers and superheaters that feature unique designs to eliminate freeze-up problems at temperatures as low as -190 degC (-320 degF).
Ambient Air Vaporizers are relatively uncomplicated heat exchangers which vaporize liquified gas by using heat absorbed from the ambient air.
Ambient air vaporizers take advantage of atmospheric “heat” to harness energy for the vaporization of liquid cryogen. Ambient vaporizers represent one of the most cost-effective means of vaporizing or re-gasifying cryogenics.
Due to this simple principle of operation, these vaporizers do not require external power.
Liquid gas passes through several interconnected tubes in various series and parallel paths.
Ambient air vaporizers are in operations in operation in a wide range of applications throughout the industry.

Application of Cryogenic Vaporizer
Satellite LNG systems are utilized in locations where piped natural gas is unavailable, receiving its supply from either stationary tanks or ISO containers and regasifying, regulating, and odorizing it to meet downstream fueling needs. Each system features customized vaporizer technologies, piping systems, controls, and cryogenic pumps (if required) designed specifically to each application and location of operation – examples being asphalt plants, burner/boilers, small power generators, and pipeline repair applications where these virtual pipeline systems have been implemented successfully.
Types of Vaporizers
The most fundamental distinction between different types of vaporizers is function. Vaporizers are used for one of two basic purposes: to generate a vapor or to transfer heat.
Vaporizers that are designed to generate vapor only from a liquid flow can be used for many different applications. Propane vaporizers are used to vaporize liquid propylene (lp) to provide propane gas to equipment. It is important for systems that require high vapor pressure or cold environments, where the natural vaporization of stored propane is not sufficient. The same vaporizers are also suitable for other fuels, such as gasoline or kerosene. This is most commonly used in fuel injection applications. In cryogenic applications, they can be used to superheat or vaporize low-temperature fluids such as liquid nitrogen or liquefied gas (between -280 degF and -420degF). They can also be used to generate steam or hot gases from liquid feeds.
Heat Source
Vaporizers can be distinguished based on the heating source for the vaporized fluid.
Ambient vaporizers channel heat from the surrounding air to vaporize cryogenic and other low temperature liquids.
DSW™ ambient vaporizers have become the industry standard and Supergap vaporizers use natural convection of air to vaporize liquefied gases
Performance Specifications
Capacity is the rate at which liquid can be vaporized by the device, specified in gallons per hour (gph), kilograms per hour (kg/h), or similar units of quantity (mass or volume) per time. This specification is typically used to rate vaporizers design for generating vapor, rather than those for heat transfer.
Maximum temperature is the maximum operating temperature of the vaporizer, or the highest temperature the system (or heat transfer fluid) is designed to reach.
Power requirements are specified for vaporizers which use electric heat or have other equipment requiring electric power. Power is typically specified in kilowatts (kW).
Operating pressure describes the maximum pressure conditions under pressurized operation at a specified temperature (typically the maximum temperature). Pressure is typically specified in pounds per square inch (psi).
