While all Perkins engines deliver high performance, those with electronic control systems  bring improved fuel performance, better machine optimisation and enhanced power delivery,  compared to their mechanically controlled counterparts. While the engine you select will  depend on what you require it to do, choosing electronic now – or upgrading later –  will provide an opportunity to boost power and performance across most applications. EU Stage IIIA/U.S. EPA Tier 3 equivalent and above engines within the Perkins range  offer you the choice of electronic or mechanical engine control. Deciding which system you need on your engine depends on what you want to use the engine  for. Electronic control allows you to control the injection of fuel more accurately to optimise  the power delivery and fuel consumption compared to mechanically controlled engines.  However, in some cases, a mechanically controlled system could be s...

ATEX  is the collective name of a number of European Union directives derived from the abbreviation French – Atmosphères Explosibles – “explosive atmospheres”. Explosive atmospheres include mixtures of gases, vapors, fog or dust with atmospheric air, capable of burning as a result of ignition. Since the operation of equipment used in explosive atmospheres poses an increased danger to humans, property and the environment, such equipment is subject to mandatory compliance with safety requirements in the form of explosion-proof certification for compliance with ATEX directives with further  marking with a single European Union CE  mark and the mark explosion protection EX. Legal basis ATEX currently has three EU directives: the  ATEX  directive 94/9 / EC  and the new approach directive  2014/34 / EU  applicable to explosion-proof equipment and the 1999/92  / EU  directive applicable to manufacturing processes. For the ...
