Production first started at Por, Baroda unit in 1998. Today, Vadilal manufactures practically all types of mixtures, to the extent allowed by the individual components’ chemical reactions or physical character. Gas mixture are used within main areas: Calibration gases and auxiliary gases for analytical purposes. Gas mixtures for use in industrial processes. Calibration gases and auxiliary gases for analytical purpose As the majority of methods of analysis are not absolute, but only produce a relative response, it is necessary to calibrate with a standard which has known composition and concentration, in order to accurately determine the content of the sample analysed. Calibration gases are therefore required to be accurate, stable and homogeneous. The concentration of each component must be specified together with a guarantee of accuracy of the certified value over a certain period of time. These gas mixtures are produced from pure raw material, with a known content of impurities. A wide variety of pure gases and liquids are available to cover a comprehensive product range. Requirements for auxiliary gases, such as carrier gases and detector gases for gas chromatography, are often not as strict as those for calibration gases.

We are offering liquid mixtures. If the components of calibration gases required contains heavy components in such high concentrations that a gas mixtures would not provide a practically applicable gas volume, it may be preferable to produce the mixture in the liquid phase. This situation is most relevant for process control, where pressure and temperature in the process ensure that the compound is in the gaseous phase, while a calibration gas must be stored in completely different conditions. There are , in general, three types of liquid mixtures: liquid phase in a gas cylinder where the mixture’s own vapour pressure is high enough to force liquid out of the cylinder. liquid phase in a gas cylinder where excess pressure of helium (or other inert gases) is added to force liquid out of the cylinder. liquid phase in a glass vial, where tests are taken with a needle through a septum. For mixture in gas cylinders, the cylinder valve with normally be equipped with a dip tube to enable outlet of the liquid. For mixtures which contain light components (such as hydrocarbons

We are offering high pressure steel industrial cylinders. All our cylinders are produced as per is-7285, certified by the bureau of indian standards (isi) and approved by the chief controller of explosives, government of india. We provide cylinders with water capacities that range between one liter and 160 literswc.

We supply cylinder valves with a working pressure of up to 250 bars, and valve threads of bs 341, din 477 and is 3224.

We offer Valve Protection Guards. Vadilal supplies valve protection guards of high-impact ABS plastic in attractive colours, mainly for portable cylinders, with water capacities of up to 20 litres. They are also available in an all-steel fabricated construction of robust design, for industrial cylinders.

We provide valve protection caps in an all-steel robust fabricated construction, or in malleable cast iron.

We are offering Industrial Equipments. Products include cylinder cascades and quads for the storage and transportation of large volumes of high-pressure gases for dispensing, like compressed natural gas, hydrogen etc, and trailer-mounted cylinder bundles for end users of high-pressure gases.

We are offering purge bottle. These cylinders have threaded necks at both the ends. They find application for purging as well as high pressure condensate water traps in compressed air lines & on-board marine vessels.

We are offering vacuum pumping services. The quickest, most cost effective way to find leaks on your system. Our technical services cater to the needs of a wide range of industries, involving large scale operations like petrochemicals, oil & gas, pharmaceuticals, electronics, automobiles, cement, construction, power plant, shipping and engineering. Benefits of having your equipment re-evacuated & vacuum tested. retain cryogenic liquid and products effectively. reduce costs on product loss. leak checking can accurately pin point small leaks. save time and money on energy use. save valuable production time and money. reduce down time. non destructive, non-invasive testing. reduce wear and tear of vacuum pumps. reduce your carbon footprint. find minute vacuum leaks. check integrity of vessels. protects the environment from dangerous emissions.
