Thermoelectric Coolers & Understanding The Peltier Effect

What are Thermoelectric Coolers? (TEC) A thermoelectric cooler is a device used for the transfer of heat that achieves the same results as traditional compressor systems without the use of a gas or moving component.... if you exclude the fan. Quite simply, thermoelectric coolers are simply small static heat pumps to transfer heat which operate according to the Peltier Effect. These thermoelectric coolers present a cost effective solution for cooling electronic equipment housed in small enclosures that provide reliable performance with the CFC'...

Gas & Commercial Kitchen Ventilation

The hospitality industry is booming, with research trends reporting that people are eating out more regularly and with more cost effective, health conscious options available there are restaurants opening each day with a hope of servicing a market with huge potential gains. But while everyone is thinking about the food that will be placed in front of them, many, unless working in the environment constantly, fail to recognise that the commercial kitchen is the epicentre of activity and in particular what a potentially dangerous place this can be...


Exhibiting at the S-Lab Show

This week we attended the S-Lab show “Science, Innovation, and Translation: The Design and Operation of Research laboratories, Incubators and Science Park Facilities” which was held at the York Racecourse. This innovative show is a unique initiative that supports innovation and laboratory improvements. To support this, during the 2 day event, as well as having numerous exhibitors showing the delegates what is new and forward thinking in the market there where continuous seminars and lectures throughout the day.  As many as 5 seminars at a ...


Woodchip Drying Using High Capacity Axial Fans

Biomass: The drier the wood chip, the more energy produced Over the last 12 months Axair has handled a large amount of Biomass fan enquiries. For those unsure of the term, Biomass predominately focuses on sustainable sources of energy found in wood chip, pellets and dried logs as opposed to using non renewable forms of energy found in fossil fuels such as coal and oil.  The simplest way of using many forms of Biomass for energy is simply by burning it. Recently, Axair has provided several long cased axial fans to facilitate the drying of t...


Understanding Static, Dynamic & Total Pressure In Air Movement

Pressure Definitions Static Pressure Static pressure is signed as Pst or sometimes on fan curves as Pfa. Static pressure is defined as “the pressure exerted by a still liquid or gas, especially water or air” This is the difference in pressure either across an element in the system, for example a carbon filter or a heating coil, or between the inside of the system and the outside atmosphere. Static pressure can be either positive or negative. Understanding the static pressure is useful when selecting the correct fan for the application. ...
