Material Handling Fans for Combustible Dust & Textile Fibres

Dust explosions can occur in any activity in which solid materials are treated and finely divided. Small sized particles are produced during manufacturing processes. Large particles fall while smaller particles remain suspended for unlimited periods. Powder is measured in microns. A micron is a unit of length equal to 10-4 (0,0001cm). Material handling fans are required where solid and bulky materials need to be handled or conveyed, for example in food processing or biomass applications. In food processing applications, the likes of flour, suga...


Fans for School Fume Cupboards

  School and University laboratories with a lot of activity generally contain several fume cupboards which helps in providing a fume free workspace. Laboratory environments in educational establishments that handle hazardous materials require specialised ventilation equipment. [caption id="attachment_4409" align="alignright" width="300"] fume-cupboard-alarms[/caption] During school science experiments and demonstrations, it is commonplace to use fume cupboards. Fume cupboards capture and remove any harmful substances generated and...

Corrosion Resistant Extraction Fans for Salt Spray Chambers

    Salt spray has a very potent effect on corrosion and not knowing how products react long term to a corrosive environment or chemical, can have devastating effects for the end user and the original manufacturer. Salt spray testing is a laboratory simulation of a corrosive saline environment that tests the performance of items on their surfaces after corrosive protection treatments including coating, galvanising, painting and anodising. Test chambers are designed so that this can be done in a controlled environment to ensure t...


Predictive, Preventive and Reactive Maintenance in Thermal Management

  Electrical equipment failures due to ineffective heat dissipation account for millions in damage and lost business every year. Ironically, more than two thirds of electrical system failures can be prevented by a routine maintenance program. Maintenance approaches can vary by application but are commonly referred to as predictive, preventive, or reactive. Each of these approaches has advantages and limitations, some becoming more frequently adopted with the availability of new technologies. Electrical cabinets control systems, autom...


Understanding ATEX Definitions for Ex Fans – Ex ec, Ex Na, Ex eb, Ex tb & Ex tc

An explosive atmosphere can be created with the presence of gases, vapours, mists or dusts, which have the potential to ignite under certain operating conditions. Potentially explosive atmospheres are found in many areas of industry, from mines, battery rooms releasing the IIC Gas hydrogen, chemical, oil and gas, pharmaceuticals industries, processing plants handling cereal, animal feed, paper, wood, coal, sugar, flour or other petro-chemical fumes and more. All these have the potential to produce gas, dust or fumes which can be ignited by even...


IIC Fans for Hydrogen Exhaust & Effective Battery Room Ventilation

  Everyone knows the function of a battery; to store electricity in the form of chemical energy and to convert to electrical energy when required. Vented lead-acid batteries or flooded batteries as they are also commonly known, consist of plates that are flooded with an acid electrolyte. When charging, the electrolyte emits hydrogen through the vents in the battery. Under normal operations, the release of hydrogen is relatively small, but this is elevated during heavy recharge periods. It’s an important consideration for battery room ...


Wastewater Treatment Ventilation: Polypropylene vs. Stainless Steel and GRP

Corrosive Gases in Water Treatment Environmental wastewater treatment plants face a number of challenges in terms of ensuring safe and effective ventilation due to the release of corrosive and toxic gases that occur across the various treatment processes. During the treatment process, the ventilation system must control hazardous substances, chemicals and gases such as methane, ammonia, phosphorous, pesticides and carbon dioxide. Consequently, wastewater treatment plants are, by their nature, one of the harshest engineering environments. To...
