Air Design has supplied the latest in a series of AHUs to the University of Edinburgh. The bespoke unit for the university’s School of GeoSciences laboratory unit – built to specific dimensions because of the size constraints of doorways, ramps and stairways on the site – is one of several units supplied to the institution by the West Midlands based manufacturer.
The unit was delivered to site in sections, before assembly and installation. The units are constructed from modular framework, comprising an aluminium frame and purpose built corners, for strength, with double skinned panels providing a rigid construction for the internal components. They can be tailored to suit internal and external mounting applications, with a variety of options that includes plate to plate recuperators, cooling coils, mixing box sections, humidifiers, dampers, filters, control panels, silencers and more. Amongst the many controls available within the range are starters, frequency inverters, damper actuators, temperature, pressure and humidity sensors, step controllers, frost protection, fan air flow and fan filter status switches.
Incorporating EC motors, the units operate with specially matched EC controllers. This coordinated system enables precise speed control of the fans with the highest degree of energy efficiency and is totally free of electromagnetic motor noises.
