Everything you need to know about Extra-Low Voltage (ELV) Systems

Oct 25, 2019

What are Extra-Low Voltage Systems (ELV)? Extra-Low Voltage means the voltage of electricity supply is in a range that is low enough that it does not carry any high risk of any high voltage electrical shock(s). The range of voltage that can be classified as Extra-Low Voltage is alternating current not exceeding 50 V AC and direct current not exceeding 120 V DC (ripple free). This is based on the standards as per EN 61558 or BS 7671. Therefore, Extra-Low Voltage S... Read More

What Are The Different Hazardous Area Classifications? If there are any electrical equipment that are installed in an area where the equipment would come into contact with flammable liquids/gases/vapors, ignitable fibers/flyings and combustible dusts, there would be a risk for fire and explosion. Such areas mentioned above that have possible risk due to explosive atmospheres are normally classified as hazardous areas or locations. There are 2 hazardous area classi... Read More

What is Trace Heating?

Jan 28, 2019

What is Trace Heating? Electrical trace heating refers to the process of maintaining or raising the temperature of pipes and vessels through specially engineered cables. During the winter season, temperatures are extremely cold and can fall below freezing levels. When this occurs, businesses can turn to trace heating as a solution to protect their important pipes and vessels from freezing at sub-zero temperatures. When temperatures drop to freezing levels, pi... Read More

How to Prevent Frost Heaving in Cryogenic Tanks

Sep 21, 2018

How to Prevent Frost Heaving in Cryogenic Tanks Cryogenic tanks are essential in receiving and storing Liquefied Natural Gas (LNG) up to -162°C which can be described as cryogenic conditions due to the extreme low temperatures. LNG is produced when natural gas has been cooled and condensed into its liquid state at -162°C. The benefit of LNG being in a liquid state is that this allows for easier transportation as LNG occupies 600 times less space than in its... Read More
