LNG is one of the most important energy sources in the world, LNG Dewars play an important role in the storage and transportation of natural gas. Our LNG cylinders use steel plates that meet international standards to ensure high product quality. The vacuum multi-layer winding technology reduces the loss during use. And the gasification system that comes with the bottle makes it more convenient for customers to use. The multi-grade testing process and the results of multiple tests ensure high product quality. We support customization of different specifications between 80L and 1000L to meet customers' needs.

Product Description

Hebei Runfeng LNG dewar bottles are mainly used to fill and store liquid natural gas for supply heat energy for rezidential and industrial places. Runfeng has been engaged in the production of dewar bottles for decades, with strong production strength and traceable enterprise history. We have a professional and experienced R&D and production team, committed to provide higher cost performance, better quality, more convenient use, and better pre-sale and after-sales service. At present, the cryogenic tanks and dewar bottles produced by our company have been insulated with high vacuum multi-layer winding insulation paper. It is lighter than the traditional process and has been widely recognised worldwide.

Main Features:

1. High vacuum insulation technology is applied to achieve higher cost performance.

2. Ultrasonic flaw detection, high quality inspection.

3. Complete with level gauge and pressure gauge and other necessary fittings

4. Famous brand pressure relief valve

Note: The maximum filling capacity is calculated based on the boiling point of the liquid under normal atmospheric pressure. The actual filling capacity is affected by the liquid temperature and pressure inside the container, which is about 95% of the maximum theoretical filling capacity, and about 90% for natural gas.

25 layers of Vacuum insulated quilt

We use 25 layers of mutiple

thermal insulated quilt to ensure the vacuum effectiveness.

Protective ring.

Each of our cylinder has two protective rings to protect the brass vaporizer coils

and pressure built coils from any deformation
