What are the advantages of cooling by hydrogen generators?

The two main advantages of cooling by hydrogen generators are its density is 1/14th of the air and its thermal conductivity is 6.7 times that of the air. These two properties of the hydrogen gas have the following advantages:
·         The noise generated by the alternator is reduced considerably due to the lighter cooling medium and lower friction.
·         Windage losses which are proportional to the density of the cooling medium are drastically reduced.
·         The reliability of the insulation increases and its life span is prolonged.
·         The cooling surface required for Hydrogen cooling is considerably smaller than that needed for the air coolers due to high heat transfer rates
·         There is no possibility of the fire hazard in the machine if the failure occurs in the winding insulation as hydrogen gas does not support combustion. Therefore, there are no needs to incorporate any fire control
·         The usage of hydrogen gas as a cooling medium compared to air permits the machine of the same dimension to have 20% greater output capacity.
·         The corona effects on the conductors in the windings are less harmful in hydrogen atmosphere compared to air.
Due to numerous advantages offered by the hydrogen cooling, it is universally accepted better cooling medium for high capacity generating units

Nitrogen Application in Cryotherapy

Image
Introduction Cryotherapy is a dermatological treatment used by dermatologists and skin care experts to treat surface skin lesions by freezing them with liquid nitrogen. Although other cryogens like carbon dioxide snow, Dimethyl ether and propane or DMEP were also used earlier, their use has now grown obsolete and liquid nitrogen is most commonly used. What Type Of Skin Lesions Are Treated With Cryotherapy? Lesions that are usually treated by cryotherapy include actinic keratosis, viral warts and sebborhoeic keratosis or senile warts. Specialist dermatologists sometimes also freeze small skin cancers such as superficial basal cell and in situ squamous cell carcinomas (intraepidermal carcinoma, Bowen disease), but this treatment is not always successful, so careful follow-up care is necessary.Freezing is one of the most suitable way of getting rid of many different kinds of surface skin lesions, asit is relatively inexpensive, safe, and reliable. However, it is also

Applications of Nitrogen Generators

Nitrogen is a quite sought after gas as it has a wide variety of industrial uses. Most of these industries, need either nitrogen or liquid nitrogen generators on-site. Nitrogen generators these days are fitted with nitrogen separation membrane technology, which is economical, simpler and more dependable than the units without it. These are industries which need nitrogen, and thus nitrogen generators. 1.       The Food and Beverage Industry: Food and beverages begin to age and perish as soon as they are produced. This is due the activity of bacteria and similar micro-organisms or oxidation. A nitrogen flooded atmosphere solves both problems by stopping these organisms from growing and preventing oxidation. 2.       The Tyre Industry: Aircraft tyres are filled with nitrogen instead of air as it is drier than air. Most premier automobile companies fill the tyres of their cars and bikes with nitrogen, as it remains at a stable pressure if and when heated or cooled. Also, being

Things to know about Oxygen Gas Plants

The Oxygen Gas Plants are carefully designed for the production of pure Oxygen Gas concurrent with the oxygen gas. Such plants use a very special kind of Expansion Engine and a bypass valve that enables the rapid and adequate cooling. The main features of an oxygen plant should include the latest technology, smooth performance, minimum power consumption and nil chances of any defects. These features allow these plants to become exceedingly stable and economically viable for the user. Presently, the oxygen gas manufacturers in India are very well developed as they offer the finest quality of these products.  If someone is looking for a full proof temperature indication as well then their feature of using an electronic system scanner seems fruitful. The system also utilizes pressure differential gauges that also boast a stainless steel control panel that indicate the accurate liquid level in the production of liquid oxygen gas. The main scope of supply of oxygen plants also i
