PTX Diesel "Two Way" Catalysts
Diesel Oxidation Catalyst
Pyroban Envirosafe’s PTX Diesel Catalyst is one of the key after treatment exhaust emission solutions, lowering harmful emissions from diesel engines.
The PTX Diesel Catalyst promotes an oxidation reaction reducing the tailpipe output of two of the gases found in diesel exhaust emissions, CO and HC.
This type of system is often referred to as an ‘oxidation’ or ‘two way catalyst’. The PTX Diesel Catalyst is designed to treat the CO and HC emissions from a typical diesel engine that can lead to various health implications including headaches, choking, lethargy and eye irritation.
How it Works

Pyroban Envirosafe’s PTX Diesel catalyst, designed and manufactured at our UK facility, gives the traditional benefits of a “two way” or oxidation catalyst, ideally suiting diesel engines, treating the CO and HC content of the exhaust fumes.
PTX diesel catalysts work by converting these gases to Carbon Dioxide (CO2) and Water (H2O).
The catalytic conversion requires a heat source, so choosing the location of the catalyst within the exhaust system is very important. The need for a heat source makes the PTX catalyst ideally suited to diesel powered equipment operating medium to high duty cycles so they can generate the heat needed for oxidation.
At low rev. conditions, the closer the catalyst is to the manifold the more effective it will be. However, with the modern ergonomic designs of todays forklift trucks, mini excavator and access platforms, we find that space is at a premium and that the preferred option for most applications is a pattern silencer based on the original equipment part.
