PpTek currently has approximately 100 installations world wide in countries such as Canada, New Zealand, Chile, Argentina, Thailand, Czech Republic, France, Italy, Spain USA in addition to the UK.

Twenty Five per cent of the installations are to replace Activated Carbon units that have become too expensive for customers to renew.

Additionally several installations have been made to protect, not only CHP engines but also, Active Catalytic Converters in areas with very strict exhaust emissions. These are extremely sensitive to being "blinded" by the silicon dioxide built up on their expensive precious metal catalysts.

BGAK2400 Siloxane Filter at Stoke Bardolph

Severn Trent Water, one of the leaders in CHP installations in the UK, recently upgraded their CHP installation at Stoke Bardolph to enable greater efficient use of the BioGas. Two new 1.15mW Jerbacher CHP's were installed to augment the aging Deutz engines. This site has had a history of bad siloxane contamination and chose to fit an automatic PpTek siloxane filter (BGAK2400) to solve their problems. With a gas flow of 2000 m3/hr the filter also protects the boilers as well as the CHP's.
