Electrical Heat Tracing vs Steam Tracing

May 04, 2020

Overview of Heat – Tracing Systems The practice of heating piping to keep the liquid in the piping at a constant/set temperature requires a heat tracing system. For the purposes of this article, we can broadly classify heat- tracing systems into two categories: Electric Fluid In the past, steam tracing has historically been a more common form of heat tracing but due to advancements in technology, electrical heat tracing has become a viable way of heat...

What are Distributed Control Systems?

Mar 25, 2020

Distributed Control Systems (DCS) In this article, we will be sharing more about distributed control systems and their various benefits and functions. As an example, within the oil & gas/manufacturing industry, different systems may be introduced to automate any processes and reduce any human intervention with these systems.  The benefits of these systems are to save cost in the long run and keep any injuries as low or avoid them if possible. Distributed... Read More

Ex e VS Ex d Enclosures – What’s the difference?

Oct 25, 2019

What are explosion proof enclosures? Explosion proof enclosures are boxes that can be made of various materials, such as aluminium, stainless steel or sheet metal. The key purpose of these enclosures is to protect the surrounding environment outside the enclosure by having the ability to contain any sparks or explosions within the enclosure itself. The enclosure itself must also be heat resistant to high heat so that any fire does not escape the enclosure itse... Read More

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

Aug 27, 2019

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
