Welcome to Cawdell Ltd

Bob Cawdell founded the company in 2005 after almost 20 years experience in the diesel emission control business.
Our focus is to provide exhaust purification solutions to suite customer needs.

We have a unique solution for light vehicles originally developed for the London Taxi Emission Strategy, and now also being adopted by Manchester taxi fleets.
Cawdell are helping many truck and coach operators meet the requirements of the London Low Emission Zone (LEZ), and as other cities introduce measures for improving air quality, Cawdell can assist by supplying and installing exhaust purification for stationary and mobile diesel engines.
We are able to fit at the customers premises or at our purpose-build new workshops in Derby.

Our products include several types of exhaust filters (DPF’s) and oxidation catalysts (DOC’s) for the control of particulate (soot), hydrocarbon, and carbon-monoxide, as well as simple “Exhaust Gas Recirculation” (EGR) device for the control of nitrogen oxides (Nox). We can customise these products to satisfy a particular customer need.

We supply & fit diesel emission control products for On-Road and Off-Road mobile applications and all stationary applications.
