We’ve heard a lot of similar questions, asked by our customers over all those years… While it would prove difficult to list all of them here, we’ve thrown in the most popular ones.
What is a Vaporizer?
A vaporizer is a device that transforms liquid phase LPG to vapor phase LPG.
How does a vaporizer work?
  • A vaporizer can be heated electrically via the heating elements in the vaporizer water chamber. The heated water in the water chamber in turn provides the heat to the LPG liquid.
  • The heating is controlled within a temperature range.
  • The controlled temperature range of 50°C to 70°C provides optimal vaporization of liquid LPG without the breakdown of heavy ends.
  • Some vaporizers can be heated up via a regulated flow of hot water which is fed through the vaporizer to provide the heat needed.
Why are vaporizers needed?
  • When vapor LPG from natural vaporization is not enough to meet high LPG consumption demands, a vaporizer can assist to provide the sufficient vaporization rate required. So vaporizers are needed when consumption is greater than natural vaporization.
Advantages of using vaporizers
  • Maximise the usage of liquid LPG in the storage tank.
  • Higher flexibility and fewer refills.
  • Achieve efficient and constant vaporization rate regardless of the liquid LPG level and temperature in the tank.
  • Constant mix of propane and butane.
Where is the vaporizer installed?
  • Zone 1 vaporizers are installed in the LPG tank farm area.
  • Zone 2 vaporizers require a safety distance from the tank farm area in accordance with local rules and regulations.
How is the vaporizer installed?
The vaporizer is connected at the outlet of the liquid LPG line of the tank. The vapor outlet of the vaporizer is piped to a set of regulators to further reduce the pressure of the vapor phase LPG to suit the working pressure of the burners.

  • Open-air installations – advisable to provide weather protection.
  • An inlet strainer and an oil separator at the outlet are recommended.
  • Fresh water is to be added fully into the vaporizer water chamber.
  • Place the vaporizer on solid foundation such as a concrete slab.
  • Pipe connections must be firmly supported on both sides of the vaporizer.
  • Electrical connections must suit the category and specifications.
Where are vaporizers used?
  • Factories and production facilities that require LPG vapor as fuel for all sorts of burners.
  • Residential areas – for cooking and heating in the home
  • Hotels and restaurants
  • Greenhouses
