LPG (Liquefied Petroleum Gas) is stored in liquid phase, but consumed in the gas phase. It is necessary to gasify (vaporize) the gas in order to be in the gaseous form, ready for consumption.

LPG tanks are a natural gasifier, which when the gas is supplied from the top of the tank is taken in a gaseous form, ready for consumption.

The LPG tank is a natural gasifier-vaporizer

There are cases, however, which is necessary to use an LPG vaporizer.

What is the LPG Vaporizer?

LPG Vaporizer are heat exchangers for the liquid phase of the liquid gas, ie they are vaporizers and are used when the gas supply necessary for the consumption can not be obtained without a Vaporizer.

Such cases are when:

  • The gas storage area is not large enough to meet the needs of the consumer under all circumstances.
  • There are space or regulatory restrictions that prevent the installation of additional tanks or bottles.
  • There is a loss of pressure during the cold months (when the tank does not work properly as a natural gas blender due to low temperatures)


Advantages of Using a LPG Vaporizer

  • The use of the LPG Vaporizer has the following advantages:
  • It neutralizes the "tank frosts" that cause production losses or delays.
  • Constant gas supply.
  • Venturiers save space. More tanks = Extra space
  • Vaporizers add overheating to propane gas.
  • Vaporizer operate at low temperatures.
  • Tanks need not be kept between 50-75% when it is cold.
  • Reduces propane feed rate and increases delivery quantity.
  • Doubles or more the ability/capacity of the system without the addition of tanks.
  • It helps to eliminate accumulations of heavy residue in the tanks.
  • 100% fuel utilization offers application versatility.

Types of LPG Vaporizers

Depending on the application, requirements and installation conditions, different types of LPG vapor are available, such as:

  • Direct Fired Vaporizers
  • Electric Vaporizers
  • Hot Water or Steam Powered Vaporizers

In addition, there are other solutions for the successful gasification of LPG in the tank, such as:

  • LPG Tank Heaters
  • LPG tanks with integrated exchanger

LPG Vaporizer (Tank Heater) Algas SDI SECOND SUN

exaeriotis second sun se dexameni

Second Sun™ is a flameless catalytic tank heater designed to safely and efficiently augment natural vaporization in propane, LPG and anhydrous ammonia storage tanks.

When our environment is unable to supply the needed energy, Second Sun is an ideal solution!

It is ideal for installation in hotels, restaurants, heating plants, poultry farms, crafts and industry.

exaeriotis Second Sun

Catalytic heating is a flameless process that involves chemical reactions aided by a catalyst. The reaction starts on an electrically heated catalyst surface causing complex molecules to rearrange as simpler molecular structures. The primary by product of this catalytic process is heat.

Second Sun emits this heat against the surface of the tank as infrared waves similar to a radiant heater.

This warm, low intensity heat mimics the energy from the sun. Since catalytic heating is flameless, Second Sun meets hazardous location requirements..

LPG Storage Tank with Internal Heater Plinoxotar Italy

δεξαμενη υγραεριου

Horizontal tank for underground installation model "NATURA" with epoxy coating and cathodic protection CE marked according to Directive 97/23/CE (P.E.D) ) by notified body ISPESL ISPEL (CE 0100).

The internal heater is composed of a shell and pipe heat exhanger, positioned in the bottom of the tank, that allows, in a simple and absolute safe way, the "controlled" vaporization of LPG with running costs extremely low when considering the throughput that can be obtained (up to 300Kg/h).

Heat exhanger and control instruments (pressotake,termometer, electric panel EExi) are included in the declaration of conformity to 97/23/CE Directive (P.E.D) and 94/9 CE (Atex) and therefore the tank installation is straightforward without any additional paperword or "Declaration of incorporation" necessary when two or more CE marked items (for example an external vaporizer and a LPG storage tank) are connected together.
