We recently provided Heathrow Terminal 5 with Low Temperature Hot Water (LTHW) Side Stream filters for its air conditioning system.

Amazon Filters provide Side Stream Filters for Air Conditioning System at Heathrow Terminal 5

View the case study here

Due to the success of the Amazon Side Stream filters installed previously at the Heathrow Energy Centre, the same system was selected for a major project initiated to ensure the high performance and accurate control of the heating system operating in Terminal 5.

The main plant rooms are located below ground and because of the construction work on site were prone to ingress of contamination. Therefore Amazon Filters recommended the use of 50μm DuoLine bag pre-filters for initial high solids removal followed by 20μm SupaPleat II cartridge filters for final polishing as a solution to this problem.

The system volume was significant – in excess of 500,000 litres of water, therefore requiring the installation of 8 filter housings in each of the two main plant rooms. The final design involved the use of four 84 Series prefilter housings followed by four 63 Series polishing filter housings, all operating at 8-10bar. To ensure minimal fluid loss from the circuit additional booster pumps were installed.

BAA Supervisor, working alongside Amazon Filters, said:

“Due to successful operation at the Energy Centre, Amazon’s Side Stream filters were selected for the Terminal 5 air conditioning system. The filters were manufactured and delivered on time and met all criteria. More importantly, from an operational perspective, they have continued to support BAA on a practical level”
