Enclosure Ventilation – An Axair Guide to Power Electronics Cooling

Fan filter kits have been in use for around 20 years and are now considered ‘part of the scenery’ and a commodity product. Their function has not changed, they are still as useful as ever; however,  if the wrong product is selected, the whole control cabinet may overheat and compromise not only the value of the equipment it contains but also the panel’s primary function, powering a whole process plant, shopping centre or datacentre, for example. The impact of this could be catastrophic so it pays to seek advice and assistance when select...


Cabinet Cooling Project Proves Axair Knowledge is Power

Bespoke solutions don’t always have to involve bespoke products. Sometimes, the best solution can be found by using standard products but applying them in an unconventional manner.  Axair regularly fulfil customer requirements in this way; a recent example being a project we supported for a well-known control systems company with some very specific enclosure cooling requirements. The enclosure in question was generating 11 kW of heat; they were attempting to dissipate the British Standard, BS60439, which specifies that the temperature out...


HGI Fan Proves Fume Favorite for High Volume Extraction

We recently supplied a number of HGI-125-T-1 axial fans to an air handling contractor that had designed a ventilation system for a PVC sheet manufacturer. The PVC manufacturing process produces a number of gases, including hydrogen chloride, and the wall mounted axial fans would allow for the control and extraction of any potentially toxic fumes from their facilities. Encased in galvanised anti corrosive metal, the belt driven HGI-125-T-1 is designed to move large volumes of air at low speed, operating at 437 rpm to produce a maximum airf...


Control Offshore Fan Systems with Remote Regulation

Remote computer connection has become common place in industrial environments, changing the way that processes and procedures are undertaken and generally enhancing the capabilities of the industrial sector. Power Generation has been a great user of these remote computer connections. On-site operatives are fast becoming a thing of the past for many power generation centres as they look to monitor operations and equipment from a central location. This can prove particularly useful when the locality of a power centre is hard to reach. Industrial...

First Class Upgrade for Ecofit Rail Fan

Most rail fans are specifically made to comply with customer specifications and the expected harshness of rolling stock railway environments. Others are simply upgraded versions of standard fans such as the Ecofit GRF single inlet forward centrifugal fan. The GRF was primarily designed for operating with HEPA filters for pharmaceutical applications and toxic environment filtration systems. It consists of a high power external rotor motor fitted in a standard single inlet scroll assembly. In order to provide extra stability for the over-si...


Axair Adaptors Help Panel Builders Get Ahead

With the UK recession causing an intense increase in market competition, many control panel builders tried to get ahead by reducing stock levels and adapting standard products to meet customer requirements. Despite reducing costs, streamlining the range of designs available has somewhat obvious limitations. Even with modification, customers can be restricted when it comes to specific requirements such as temperature control or prerequisites on space. Thanks to our partnership with Italian experts, Fandis, Axair Fans can offer panel builde...


Italian Fans Help Keep Pope On Air

Almost 400,000 people have been known to flock to the Vatican City in Rome during the election of a new Pope. With that many people all vying for a look at one man, in 2007 the Vatican took the somewhat inevitable step of installing a number of large plasma screens in the city’s St. Peter’s Square region. The screens have become a permanent fixture in the square, broadcasting the Pope’s weekly address and his Sunday prayers. With some of these events lasting almost 4 hours, it’s important that these screens don’t overheat in the Ita...
