Purpose Of Low Temperature Testing













How exactly does cold affect machines? To start off, matter contracts when exposed to cold temperature. This contraction can cause tolerances between mechanical components to change. It can lead to tightening or loosening of tolerances. Overly tight tolerances can increase wear due to friction. It can also increase power consumption since the power generator has to work harder to overcome the restrictive friction. In combustion engines, loose tolerances reduce mechanical power output, In oil-lubricated machines, cold hinders the circulation of oil. This happens because oil thickens when cold. It doesn't circulate well, making it difficult for a machine to get properly lubricated. This can speed up wear. Cold affects performance and longevity of the machines.


Cold testing, also known as low temperature testing, is done to determine how a machine or engine behaves under low temperatures. It is needed to make sure that machines are able to operate properly and safely even in cold conditions. Cold testing chambers are used.


Cold chambers are not that different to cold storage used for food products. However, instead of ordinary refrigerants, a special type of heat transfer fluid is used. A low temperature testing fluid is designed to be more efficient at transferring heat. The testing fluid is formulated for the demanding requirements of cold testing. A cold testing chamber can produce much lower temperatures compared to an ordinary cold storage.


Large manufacturing facilities have their own cold testing chambers. Smaller operations rely on third party companies to perform cold tests.

Food Refrigeration And Keeping Up With Food Safety Standards



Food refrigeration is very important. It extends the shelf life of food. This ensures sufficient supply of food and preserves the quality. It also reduces throwaways

. Very few things can be compared to refrigeration technology when it comes to its contribution to the explosive advancement of the society.


Food refrigeration is covered by food safety standards. Food safety standards are created and implemented to protect the well-being of consumers. It prevents health and other complications resulting from consumption of unsafe food. It specifies how food should be handled and processed, and what chemicals are allowed to be used near food.


There is a potential danger to food refrigeration. Although intended to preserve quality and safety of food, the opposite can happen when something goes wrong. Contamination from a leaking refrigeration system is a serious concern. Ordinary coolant or heat transfer fluid is toxic. A truckload of food can inconspicuously become very dangerous.


This is why the use of heat transfer fluid designed for food refrigeration is an important stipulation in food safety standards. Food refrigeration heat transfer fluid must pass toxicity requirements. Many heat transfer fluid for food application are colored to make it easier to identify a leak or contamination

Chemical stability is also an important property. Chemical stability is the property of any chemical to resist chemical reactions. Safe chemicals can turn deadly when mixed and reacted other chemicals. This is why food refrigeration heat transfer fluid must be chemically stable.

Fire Suppression Antifreeze Prevents Winter Fires



House fires are more prevalent during the winter months. Some fires end up in a tragic loss of lives and total destruction of properties. This trend is hardly surprising. If you look at the activities and how people behave during winter, it is easy to understand why more fires happen during the coldest months of the year.


Winter shortens daylight, brings cold temperatures, and arrives together with the holiday season. House lights have to be turned on longer. Heating appliances are being used to keep warm and comfortable. Christmas lights and other electrical decorations are everywhere. These increase the load on electrical circuits of houses, thereby increasing the risk of electrical malfunction which is the most common cause of winter house fires.


Growing number of houses have fire suppression installed. Aside from putting out and preventing the spread of fire, it can also benefit homeowners in the form of lower insurance premium.


A fire suppression system can fail, especially in the winter. The freezing winter temperatures turn water within the system into ice. In the case of the fire, no water would come out of the sprinklers. The system designed to protect becomes incapable of doing its job


In countries with freezing winters, fire suppression antifreeze is very important. The antifreeze is an additive that lowers the freezing point of the water so that it doesn't turn into ice in extreme cold. Antifreeze additives lose their efficacy over time. A fire suppression system must be topped up with the antifreeze periodically.


A fire suppression antifreeze ensures that the fire suppression system is there and ready to perform its duties when the need arises. It helps keep lives and properties safe during winter.

Energy Efficient Heat Transfer Fluid









A heat transfer fluid is a fluid that facilitates transfer of heat. It is used for cooling and heating. An example is the engine cooling system in a vehicle. Heat is drawn away from the engine by the heat transfer fluid that flows around it and absorbs heat. As it absorbs heat, the heat transfer fluid becomes hot. The hot transfer fluid is then sent towards the radiator where it is cooled then cycled back to the engine where it will again absorb heat.


Energy efficient describes any process optimized to reduce the amount of energy required to complete the process. So what makes heat transfer fluid efficient? In an engine, energy is used to power the pump to circulate the heat transfer fluid. An energy efficient heat transfer fluid is, therefore, one that allows the fuel pump to work less hard. Heat capacity and viscosity of the heat transfer fluid are the primary players in its energy efficiency.


Heat capacity or amount of heat that the heat transfer fluid is able to absorb. Higher heat capacity means the heat transfer fluid is able to remove more heat from the engine per cycle. The greater the amount of heat is absorbed from the engine per cycle, the fewer cycles are needed to lower the temperature of the engine to ideal levels. This lessens the amount of work for the pump, thereby allowing it to consume less energy. Viscosity is the resistance of fluid to flowing. A heat transfer fluid with the ideal viscosity allows the pump to circulate the fluid easier. Less work also means the pump has longer life before servicing


The primary beneficiary of energy efficient technology is the environment. However, as in the above example, it can help increase the life of certain components. This makes energy efficient heat transfer fluid very beneficial.
