The Importance of Diesel Generators in Health Care Industries !!!

Health care industry has become an integral part of our lives and it is difficult to imagine our survival without presence healthcare facilities. Thanks to the advanced technology utilized by hospitals and other health institutions, we are able to cure several diseases that we could have otherwise never cured without it!
Many of these incredible pieces of technology, like the surgical equipment and monitors, operate on electricity. Any power outage during a critical surgery or treatment can be life threatening for the patients. Wouldn’t it be incredibly dangerous for hospitals if there was a power outage? Thanks to the Diesel Generators, the answer is “no”!

The Generators Used in the Health Care Industry :-

With power blackouts being unpredictable and devastating for hospitals, it is necessary for hospitals to have a back-up generator running electricity for at least 24 hours. In hospitals, there are two types of Diesel Generators that are often utilized.
 The first type operates on a lot of natural gas and typically requires regular fuel refills but is easy to maintain. Therefore, many utility companies recognize this generator as a main generator rather than as a back-up.

The second type of dg set, which is usually used as a back-up, operates on diesel fuel. When this DG set utilizes one tank full of diesel, it can last for 8 hours. Otherwise, depending on the size of the hospital and the amount of fuel available on site, this DG set can act as a back-up for a minimum of 24 hours!

An electrical shortage at Hospitals vs At Home:-

What if there wasn’t a Diesel generator acting as a back-up at hospitals? If hospitals couldn’t maintain power, people who are gravely ill and injured would be the most at risk. Monitors, oxygen pumps and other valuable equipment can stop working and communication within the hospital, including emergency services could stop working as well. In the worst case scenario, a lack of a back-up generator could result in deaths!

However, this is not often the case at places like homes. It would be an inconvenience if the electricity goes off but it wouldn’t result in life threatening situation.

Overall, it is very important for the health-care industry to have a back-up diesel generator. A diesel generator is so important to places like hospitals that without it, it could seriously affect people. We, at Mahindra Powerol, realize the importance of Diesel Generators in places like hospitals, ensuring that we provide our customers with dg sets of the highest standard and offer after sales services of highest standards.

Air-Cooled Engines vs. Liquid-Cooled Engines

An internal combustion engine generates heat in order to produce power. However, only a small percentage of the heat can be utilized for the conversion of power into mechanical force. The rest is discarded either through the exhaust, cylinder walls, cylinder heads, crankcase walls or engine oil.
To remove the waste heat in the most efficient and reliable manner possible, engines are either air-cooled or liquid-cooled.

Air-Cooled Engines:-

Air-cooled engines have an increased surface area for quicker heat exchange and usually have fins on them. Air-cooled engines have a high heat tolerance, which means the parts of the engines are rated to perform over a higher temperature range. This is very important in extreme conditions such as during extremely hot summers. The parts of the engine are made in a way to accommodate the expansion of the metal in the hottest of climates.

Liquid-Cooled Engines:

Liquid-cooled engines have their heads without fins and are surrounded by a water cooling system. Although the term ‘Water-cooled’ is more popular term for these engines, of late, the water in the radiator is replaced by Ethylene Glycol based coolant which has got better thermal conductivity than water. The coolant is used to keep the temperature of the engine at an optimum level. The coolant flows through the channels and absorbs the engine heat and transfers it out of the engine through radiator fan. The flow pattern, rate, temperature and pressure can all be adjusted in order to provide maximum cooling effectiveness without increasing the surface area of the cylinder head or walls.

Which is Better?

Generally, both of them have an equal number of advantages and disadvantages.
Below are the features of both types of engines:

a.Air cooled engines have lesser moving parts and hence less maintenance is required.

b.Setting up a cooling package of a Liquid cooled engine is complex affair as many hoses, pipes and accurate sizing of radiator is required.

c.With the same size of engine, a liquid cooled engine produces more power compared to an air cooled engine.

d.Due to higher thermal conductivity of Ethylene Glycol based coolant, liquid cooled engines are more efficient in removing heat and thus can operate at full load at longer time duration's.
