Understanding Electromagnetic Compatibility

EMC (Electromagnetic Compatibility) testing exists to ensure that your electronic or electrical devices do not emit a large amount of electromagnetic interference (known as radiated and conducted emissions) and that your device continues to function as intended in the presence of several electromagnetic phenomena. Regulatory bodies around the world have placed limits on the levels of emissions that electronic and electrical products can generate. Also, electromagnetic immunity testing is mandated for some areas and some product types. EMC m...


Dilution & Local Exhaust Ventilation for Shipyards

One of the major hazards associated with working in maintenance shipyards is the impact of poor air quality. Those working in confined spaces may be subject to stagnant air as a result of insufficient airflow or toxic and hazardous contaminants as a result of source pollutants. Ventilation is required to ensure the correct level of oxygen needed to dilute and remove contaminants such as CO2 and hydrogen sulphide, in addition to comfort cooling or heating. In general, there are two common methods of shipyard ventilation; Dilution Ventilation ...


Industrial Fans for Ballast Water Treatment Systems

Finally coming into force on 8th September 2017, the International Convention for the control and management of ships’ ballast water and sediments, places an emphasis on involved parties such as ship owners and manufacturers to give full provisions to minimise, prevent and ultimately eliminate the transfer of harmful aquatic organisms and pathogens through the control of the ships ballast water. The spread of invasive aquatic specifies into the sea can cause havoc for local ecosystems, affects biodiversity and leads to economic loss. The conv...
