What is Heaterless Vaporizer?

Posted last June 22, 2018, 7:52 am in Services report article

To vaporize liquid LPG for various applications, LPG vaporizer manufacturers have come up with the heaterless vaporizers. It is definitely a better alternative to the conventional electrical vaporizers in many ways. To understand why the heaterless LPG vaporizer is better, let’s find out how it functions and what its underlying benefits are.

How does the heaterless vaporizer work?

The heaterless vaporizer or HLV utilizes the principle of thermodynamics wherein its design reduces the temperature and pressure of liquid LPG. Unlike the conventional electrical vaporizer, a heaterless vaporizer, as the name suggests, eliminates the need for electrical heaters to produce heat for vaporizing the LPG.

In a conventional electrical vaporizer, the liquid LPG is passed through a hot water bath where electrical heaters are used to heat the water and maintain the temperature.Here, the liquid LPG gets vaporized by absorbing the heat from the surrounding water bath. Heaterless vaporizer, on the other hand, uses a heat exchanger to vaporize liquid LPG.

In HLVs, the required temperature and pressure are maintained by continuous and closed-loop flow of water from a storage tank. The Heaterless LPG vaporizer system is designed in such a way that it does not require an external supply of electrical power for supply of heat. The only electric supply required is for running the water pump.

The thermodynamic characteristics of volatile liquids are taken into account in the design of the heaterless vaporizers. What actually happens? The fluid is flash evaporated by throttling the flow. The fluid is passed through a pressure reducing valve and then, the drop in pressure leads to chilling.And the ambient water supplies the required heat for vaporizing the fluid.

Benefits of Heaterless Vaporizer

Some of the key advantages of using heaterless vaporizers are as follows:

  • Performance

Heaterless LPG vaporizers are capable of satisfactory functioning at ambient temperatures of up to 4° C.Instrumentation such as interlocks, liquid level pressure switch, water flow switch with fire safe ball valves etc. ensure safer operations.

  • User-friendly Operations

Industry-recognized LPG vaporizer manufacturers offer a simplified control panel with the system.User-friendly panels to operate the instrumentation makes the heaterless vaporizer comfortable for use by operators. Less maintenance means fewer problems to tackle for operators as well.

  • Huge savings

The absence of electrical heater leads to less energy consumption for the LPG liquid vaporization process. Also, an optimized workflow with fewer maintenance expenses leads to more savings in the long term. Although the initial investment is high for a heaterless vaporizer, the low cost of operations can help recover the cost in 2 to 6 months as per running time.

  • Eco-friendly

Low energy usage reduces the carbon footprint. It ensures that you are using a more energy-efficient and environment-friendly process for vaporizing LPG.

To conclude, with heaterless LPG vaporizers, the consumption of electrical power can be minimized considerably and the carbon footprint is also less. In addition, you can save on the cost of operations considerably. Heaterless vaporizers are safer and require less maintenance compared to the electrical vaporizers. In the long term, heaterless vaporizers are more cost-effective as well.
