Industrial vaporizers are heat exchangers that convert liquefied gases to a warm gaseous product. The heat source can be ambient air, steam, or water. There are many types of industrial vaporizers. Examples include a cryogenic vaporizer, convection vaporizer, conduction vaporizer, and an ambient vaporizer. A cryogenic vaporizer is used for cryogenic fluids which have a temperature range of -280 to -420 °F. A convection vaporizer works on the principle of convection, which is the transfer of heat by currents within a fluid. A conduction vaporizer works on the principle of conduction. An ambient vaporizer takes heat from the surrounding air and transfers it to liquid product flowing through its coils. Other industrial vaporizers are commonly available.

There are several ways in which industrial vaporizers function. Vaporization takes place when liquids vaporize and replace the vapor that is being withdrawn from the top of the tank. A vaporizer is needed if the heat from the air surrounding the tank is not sufficient or cannot flow through the walls of the tank fast enough to maintain the vaporizing rate. If sufficient heat is not available, the pressure in the tank will drop causing a system shut-down. The purpose of vaporizers is to change the cryogenic liquid to a gas. This process always requires energy. Energy is transferred in the form of heat. The criteria used to determine how much and how fast heat is transferred are surface area, temperature difference, and heat transfer coefficient. The total energy required is a function of how much gas is required, how fast it is needed, and the energy available. Energy to vaporize liquid oxygen, nitrogen, argon, or hydrogen by an ambient vaporizer is obtained from the surroundings. The air outside the vaporizer wall is much warmer than the cryogenic fluid (-280 to -420 °F). Heat is transferred or pushed across the wall or fin of the vaporizer into the cryogenic liquid. An industrial vaporizer acts as a heat exchanger for efficient heat transfers from one fluid to another, whether the fluids are separated by a solid wall or the fluids are in direct contact. Industrial vaporizers are designed and manufactured to meet most industry specifications.

Industrial vaporizers are used in many applications. Some examples include their use in refrigeration, air conditioning, space heating, power production, and chemical processing. Industrial vaporizers should adhere to various standards specified by the American Society of Mechanical Engineers (ASME).
