Pollen ‘explosion' threat to HVAC equipment this summer

Indoor air quality specialist ECEX is warning businesses that the detrimental effects of pollen on HVAC units – including air-handling units (AHUs), chillers and cooling towers – are threatening general system efficiency and essential cooling for equipment such as data centres. The problem is at its peak this time of year as tree and grass pollen culminate in a literal “explosion” over the summer months.





In a bid to tackle the issue head on, the firm is encouraging organisations to look at installing ECEX Air Intake Screens: a simple technology that has been proven in independent field trials to not only prevent filters from clogging, but also reduce energy consumption, CO2 emissions and maintenance, with very rapid payback.





During a recent install at Westminster City Hall in London, the screens were fitted to two AHUs, with the following results:



 

  • 49% reduction in power consumed by just one unit;
  • carbon savings of 296.33kg – the two units together achieved savings of 438kg, the equivalent of taking a car off the road for a year;
  • payback was accomplished in 13 months in energy savings alone;
  • a reduction in maintenance requirements, as the filters need replacing less often and this leads to reduced costs, potentially pushing the return on investment of ECEX Air Intake Screen installation to less than four months.

Amey’s site mechanical and electrical manager, who helped co-ordinate the installation in London, explained: “Following the installation of the Air Intake Screens [at Westminster City Hall], we will achieve CO2 emission savings from just these two AHUs of over 5,000Kg per annum, equivalent to taking one car off the road for a whole year.”





ECEX managing director John Grenville said: “Pollen, leaves, insects and general airborne debris can have a dramatic, negative effect, pushing up energy usage and a building’s carbon footprint. ECEX Air Intake Screens offer facilities managers the opportunity to cut costs, reduce maintenance and increase the life of internal filters by up to 60%.”
