Herald Infratech

About Us

In 2014 we Started to trade Liquid Nitrogen on our own 2 no. of tanker, we have started this journey of new era of Herald Group. Arranged few big industries to sell their byproduct of Liquid Nitrogen to generate revenue out of it. Developed consistent demand and market of Liquid Nitrogen all over in Gujarat. Started services of purging to various industries like IFFCO, GNFC, Reliance Industry Ltd. Currently handling over 33 tankers dedicated to Liquid Nitrogen supply to various customers and become the biggest supplier of Liquid Nitrogen who is not manufacturer of the same. We sell between 1500 MT to 2000 MT of Liquid Nitrogen per Month since last financial year.


What Is

Liquid Nitrogen

Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature. It is a colorless clear liquid with a density of 0.807 g/ml at its boiling point (−195.79 °C (77 K; −320 °F)) and a dielectric constant of 1.43. Nitrogen was first liquefied at the Jagiellonian University on 15 April 1883 by Polish physicists, Zygmunt Wróblewski and Karol Olszewski. It is produced industrially by fractional distillation of liquid air. Liquid nitrogen is often referred to by the abbreviation, LN2 or "LIN" or "LN".

Liquid nitrogen is a cryogenic fluid that can cause rapid freezing on contact with living tissue. When appropriately insulated from ambient heat, liquid nitrogen can be stored and transported, for example in vacuum flasks. The temperature is held constant at 77 K by slow boiling of the liquid, resulting in the evolution of nitrogen gas. Depending on the size and design, the holding time of vacuum flasks ranges from a few hours to a few weeks. The development of pressurized super-insulated vacuum vessels has enabled liquefied nitrogen to be stored and transported over longer time periods with losses reduced to 2% per day or less.


What Is

Liquid Oxygen

Liquid Oxygen is Oxygen in a liquid state at an extremely low temperature. It is a pale blue color liquid with a density of 1.141 g/cm3 lightly denser than liquid water, and is cryogenic with a freezing point of −218.79 °C; −361.82 °F) and a boiling point of −182.96 °C; −297.33 °F at 1 standard atmosphere. Liquid oxygen has an expansion ratio of 1:861 under 1 standard atmosphere (100 kPa) and 20 °C.

Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent.

In commerce, liquid oxygen is classified as an industrial gas and is widely used for industrial and medical purposes. Liquid oxygen is obtained from the oxygen found naturally in air by fractional distillation in a cryogenic air separation plant.
