How LPG Vaporizers Work. The Best Types for Industry

An industrial LPG vaporizer functions by applying heat to the pressurized liquid LPG coming from a storage tank. As the liquid enters the vaporizer, it is exposed to a controlled heat source, either electrical or flame-based, which raises its temperature to the boiling point. This causes the liquid LPG to change phase into vapor. The resulting gas is then regulated in terms of pressure and temperature before being distributed to the industrial system where it is needed.

The process is typically automated and monitored with safety controls to prevent overpressure or overheating. Vaporizers are especially important in environments where high consumption rates or cold climates would otherwise cause pressure drops, uneven fuel delivery, or system failure due to poor natural vaporization.

Not all vaporizer technologies are equally suited for industrial operations. The two most reliable and widely used types in this segment are:

Electric Vaporizers

An electric vaporizer uses electric resistance elements to heat the liquid LPG. It offers precise control, clean operation, and minimal maintenance, making it ideal for indoor industrial settings where electrical power is readily available. The advantages of electric vaporizers include the following:

• Zero emissions at the point of use.

• High accuracy in temperature and flow control.

• Safer in hazardous environments (no flame).

• Quiet operation and easy automation.

Usually, this type of vaporizer is employed in chemical plants, manufacturing facilities, food processing, and indoor fuel systems.

InDirect-fired Vaporizers

The KBV gas vaporizers operate by indirectly heating the liquid phase of Liquefied Petroleum Gas (LPG) using a water bath. This process is facilitated by a gas burner with a sealed combustion chamber. As the liquid propane is heated, it undergoes phase transition, converting from a liquid into a gaseous state.  

The main benefits of it are as follows:

• No need for electrical connection.

• High vaporization capacity.

• Suitable for large-scale or remote installations.

Typically, they are used in construction sites, mining operations, large agricultural applications, and emergency backup systems.

Selecting the relevant vaporizer depends on several operational variables. The most important consideration is vaporization capacity, which must match your system’s peak LPG consumption rate. The availability of energy at your site also plays an essential role. If electricity is reliable and the matter of emission control is important, an electric vaporizer is likely the best fit. However, in situations where access to power is limited or mobility is required, a indirect-fired vaporizer may be more practical.

Installation conditions must also be taken into account. Electric units perform best in indoor environments with stable temperatures, while indirect-fired models are more appropriate for outdoor or temporary setups. Compliance with safety standards should not be overlooked, particularly in industries involving flammable or explosive substances. Finally, operational costs and maintenance availability should be considered, as both types differ in service frequency and energy efficiency depending on local resources.

Nowadays, LPG is used practically in all fields of endeavor, and the tendency for it is growing year after year. The next diagram shows a vivid example of LPG employment divided by sectors concerning its application.
