Cummins Explosion Protection Engine Kits (ATEX)

Pyroban has developed a range of explosion protection safety kits for Cummins diesel engines intended for Zone 2 hazardous areas. 

The original M11 engine was developed in partnership with Cummins.  Since then we have offered Pyroban solutions designed for reliable and efficient performance in harsh, offshore environments to eliminate the ignition risk on these engines.  The KTA 19 and 6CTA 8.3 require our proprietary coating solution to keep the cylinder heads and turbo transitions in compliance of T3. These parts can be sent to our UK factory for the coatings to be applied. Or alternatively you may wish to have us package the engine for you.

All flame non-transmission testing (FNTT) has been completed at our UK facility in strict accordance with industry standards such as ATEX 2014/34/EU.

Optimise your integration project

Pyroban kits are provided with component level certification to enable the kit integrator to complete the certification and test process accordance with regional legislation and demands. Kits can be enhanced with control systems, electrical apparatus and items from our component range of accessories to suit the demands of the project. World-wide installation assistance and thermal imaging is also available and full training can be provided.

  • Equipment Group: II
  • Category: 3G
  • Gas Group: IIA
  • Temperature Class: T3

Conformance to the Temperature Class is dependent on ambient operating temperatures so the installed kit must be tested in a safe operating zone before use in a hazardous area. For ambient operating temperatures above 45°C consult your customer services representative. ATEX-designed and tested exhaust system, compliant to EN 1834-1 Consult specific engine documentation for full details of what is included.
