A single adsorption dryer module consists of two chambers filled with desiccant adsorption material. The addition or removal of modules from each dryer unit will allow the dryers capacity to be flexibly adapted to the customers requirements. The module is built up into a dryer with a maximum 10 modules per unit. The modules are formed from twin cavity high tensile Aluminium extrusion commonly called columns. The dryers themselves can be installed in parallel and by adding more or less dryer units to suit whatever air demand exists on the customer site. This can be done with the minimum of installation cost. Air treatment capacity expansion is easily accommodated at a later date by adding additional units as and when system demand dictates. A reduction in air demand is also easily catered for by simply switching off dryer units thereby matching the precise system demand requirements. The modular dryer design gives total installation flexibility matching the specific needs of the user at all times. This design concept has been recognised via the presentation of a Queens Award for Technology and a Design Council Award.
