DEED - Dekati Engine Exhaust Diluter

DEED is an all new PMP-conform engine exhaust conditioning system. In contrast to multi-stage dilution systems in general, DEED is a simple, easy-to-use system that conditions the sample precisely and in a repeatable manner every time. DEED fulfills all requirements and recommendations of the upcoming exhaust fine-particle measurement legislation (PMP).

Dekati approach to sample conditioning according to PMP

Dekati has offered solutions for dilution and conditioning of automotive exhaust for over 10 years with experience on both research and routine measurements. The Dekati approach to PMP-conditioning is based on this experience and on proven, robust techniques which have been thoroughly tested over the years.

The main design criteria of the DEED have been utmost simplicity, ease of use and reliability. It is extremely easy to operate: switch on, warm up and go! No special user training is required to operate the system.

One of the other ideas kept in mind during the design of the DEED has been to minimise particle retention inside the system. This directly leads to less service needs and minimum instrument downtime. The DEED has also been designed not to have any parts that wear and tear to avoid problems that could otherwise appear in long-term continuous use. The entire instrument is contained in a single-rack mountable cabinet, and can be controlled with AK-protocol.
