Answers to 5 commonly asked questions 1. If you’re using a 110V power supply, a 3KW electric heater draws over 27 Amps – you should use a 32A plug and connector on at least a 4mm2 cable 2. Be aware of the effects and damages of voltage drop – for a 110V, 4mm2 cable drawing up to 32A, 20 metres is the maximum length you should be using – if you increase the cable size to 6mm2 you can safely extend to 32 metres – anything beyond these lengths is risking power loss and damage 3.

If you don’t know what type of mobile heater to use for your site, factory or warehouse, here are some helpful tips to help you decide on the best option for you. Heating air increases its capacity to hold water and therefore reduces its relative humidity. Air can be heated in two ways: 1. Directly (the air comes into contact with the heat source) or 2. Indirectly (the air bypasses the heat source through a heat-exchanger). Direct heating gives a heating efficiency of almost

With 93% of our world’s children breathing toxic air every day, and with hundreds of thousands of children dying each year due to respiratory infections, what is this telling us about the sustainability of a quality global workforce? A recent survey by CCS (Considerate Constructors Scheme) reveals that out of 84% of UK construction workers recognising that air pollution is a current issue on sites, 64% feel that the industry is not doing enough to address it. However, it’s mo

Hats off to all those who are making batteries work for us! Epiroc, for one, have launched their second generation of battery-powered mining machinery in recent months, so how long before the cutting edge of global mining is totally remote-controlled and battery-powered? With all the fantastic developments in battery technology, it’s interesting that the diesel engine isn’t going away quickly. Engineers are continuing their development of the combustion engine, which is set t

It feels almost intuitive that the moving air would help keep you cool. After all, that's what a breeze does and, in a pinch, waving a folder in front of your face on a hot day will provide a little relief. But since temperature is a feature of the molecular properties of a substance, the air itself isn't made any cooler by movement—it just makes us feel cooler when it blows by. On a hot day—or on a not so hot day if it's "wind chill" you're talking about—moving air helps you

The international standard ISO 16890 categorises particulate matter as PM10, PM2.5 and PM1 which respectively defines the air concentrations in liquid or solid particles whose diameter is below 10, 2.5 and 1 micron. These are the particles that pose the greatest problems to health because they are inhalable, potentially getting deep into the lungs and absorbed into the bloodstream. Impact on the lungs - Course particles (larger than PM10) are retained in the upper airway - PM

Read what London is saying about diesel emissions here https://nrmm.london/content/retrofit-technology and have a think about how it could affect you. Retrofit abatement technology (RAT) is available to reduce diesel exhaust emissions to a compliant standard. Anyone running an NRMM fleet (Non-Road Mobile Machinery) will know about the requirements of London’s LEZ (Low Emission Zone) and the need to comply with respect to exhaust emissions. Realistically, what this means is th
