Camfil Bags Contract To Work With Pfizer

Camfil Farr has been working closely with the capital projects team at Pfizer global research and development to help them realise significant savings on existing HVAC plant serving laboratory and R&D facilities on their site.

In 2006, Camfil undertook several trial installations in Pfizer building 500 and they were extremely successful. Energy savings and savings in operational costs, due to improved filter efficiency and reliability and fewer maintenance interventions, were achieved and therefore Pfizer wished to roll this out to another 9 important buildings in 2009, as part of their site energy reduction initiatives.

The project scope was to replace the filter banks on a number of existing air handling units (AHUs). The work undertaken consisted of filter framework modification and renewal, installation of new gauges, deep-cleaning the AHUs and fitting high-efficiency and low-energy F7 grade air filters.

David Mellon, said: “This prioritised energy-reduction project at the Pfizer site demonstrates that understanding the base criteria for running expensive HVAC plant is key to maintaining lean and agile facilities in the face of economic uncertainty and volatility in energy prices. The fact that an air filter does not have a 3-pin plug on it does not mean that it does not affect energy consumption.

“The more effective surface area presented to the air flow reduces resistance and therefore energy consumption. In this case it will be 17%. Other benefits we at Pfizer can now see with this work, but that were not necessarily apparent until now, include reduced change frequency of the filters and thus less waste disposal, reduced energy consumption, reduced C02 emissions and of course saving Pfizer money.”
