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.
