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 that vaporize liquified gas 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 regasifying 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 operate in a wide range of applications throughout the industry.

Application of Cryogenic Vaporizer
Satellite LNG systems are utilized where piped natural gas is unavailable, receiving its supply from 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) explicitly designed 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 primary purposes: to generate a vapor or to transfer heat.
Vaporizers designed to generate vapor only from a liquid flow can be used for many applications. Propane vaporizers vaporize liquid propylene (lp) to provide propane gas to equipment. It is essential for systems requiring high vapor pressure or cold environments where the natural vaporization of stored propane is insufficient. The identical vaporizers are also suitable for other fuels like 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 generate steam or hot gases from liquid feeds.
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
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 designed for generating vapor rather than those for heat transfer.
The 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 that use electric heat or have other equipment requiring electric power. Power is typically defined in kilowatts (kW).
Operating pressure describes the maximum pressure conditions under pressurized operation at a specified temperature (typically the maximum). Pressure is generally defined as pounds per square inch (psi).
