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 sufficient for constant  speed or elect

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 first time, the ATEX directive 94/9 / EC for equipment used

HIERSUN POWER GENSET LOAD TEST PROCEDURES GENSET A common base frame skid mounted genset comes with radiator cooled diesel engine coupled to industrial brushless alternator. 1.     OBJETIVES 1.1.        To ensure that the diesel engine is operating satisfactorily without undue vibration and overheating. 1.2.        To ensure that the diesel engine is able to sustain prolong running on full load without any sign of straining and abnormalities. 1.3.        To ensure that the safety shutdown devices are operative. 1.4.        To check on any other operating characteristic (not standard) if required by the client. 1.5.        To verify the fuel consumption against specification data of diesel engine. 2.     MEASURING AND RECORDING INSTRUMENT All electrical recording such as voltmeters, ammeters, frequency meters, hour run meters, factor meters including volts, amperes and frequency are installed in the control panel in the control room. 3.     DUMMY LOA

10 Units Cummins 4B Series Diesel Generator Set Ready Shipped  Cummins Diesel Generator Set Powered By Cummins 4B series engine with Stamford Alternator. The Cummins B Series is a family of diesel engines produced by American manufacturer Cummins. In production since 1984, the B series engine family is intended for multiple applications on and off-highway, light-duty, and medium-duty. In the automotive segment, it is best known for its use in Dodge/Ram pickup trucks.                  Since its introduction, three generations of the B series engine have been produced, offered in both inline-four and inline-six configurations in multiple displacements. The B-series features engine bores machined directly into the block (rather than the wet liners used on earlier Cummins engines). It was also set apart by the use of a shallow one-piece head, requiring closer tolerances than in other Cummins products. The engine wa

Marine generator VS residential or industrial generator A marine generator differs from the ordinary residential or industrial generator in that it is designed and constructed to withstand the moisture and corrosion problems associated with the marine environment. This reflects on the engine critical components with anti-corrosion device and design, better grade components, and wet exhausted manifold. In case any corrosion cause to the engine block, pipeline radiator or heat exchanger or cooler, these surface fitted zinc coated.  As for alternator, it comes with higher grade insulation system of the marine alternator (H class) against the ordinary one, better water-proof, anti-corrosion and protection system. Stator and Rotor winding device better to guard the alternator from damage. Therefore, comparing same power diesel generator set, marine generator constructed to be under sea-water condition, and have more durable performance, require technician understanding generator,

Cummins Diesel Generator Serving Data Center Contact us for more information about the solution Data centers house the computers, servers, switches, routers, data storage devices and related equipment used to operate the digital economy. They can be relatively small facilities owned by a single company and dedicated to processing its data alone Computers and other electronic equipment will crash at the slightest disruption or fluctuation in their supply of electricity. The power system was not designed for these sensitive electronic loads and is inherently unable to meet the technical requirements of the information economy. For data centers, which play a central role in the information economy, crashing computers cause potentially catastrophic financial losses. The same voltage sag that causes the lights to dim briefly can cause a data center to go off-line, losing large sums of money, for many hours. Hiersun power provide of standby power systems, especially data cente

The phrase “ATEX certification” is often used in engine starting, but what exactly does it mean? If you operate an offshore platform or underground mine – or if you supply products to companies that do – ATEX certification means safety. The directive 2014/34/EU, which is a revision of the current 94/9/EC directive, was published in the official journal of the European Union dated March 29 th 2014. Since that date, complementary information on its application has been issued: here is an update on the information available at this date The name ‘ATEX’ is short for “Atmospheres Explosives”. It is a strict set of regulations that applies to products intended for use in any hazardous working environment. Products are categorized according to the level of hazard that exists in the zone they will be used. Main changes § The EC declaration of conformity becomes an EU declaration of conformity. § The EC type-examination certificate becomes an EU type-examination certificate. § Imp

There is always a risk of a fammable hydrocarbon release in the oil and gas industry. When the release comes into contact with air and an ignition source, an explosion can happen.  Oil & gas and chemical industries generated many accidents (fire ,explosion). In a situation in which there may be an explosive (flammable) atmosphere , the following steps should be taken: a) eliminate the likelihood of an explosive gas atmosphere occurring around the source of ignition, or b) eliminate the source of ignition. Where this is not possible, protective measures, process equipment, systems and procedures should be selected and prepared so the likelihood of the coincidence of a) and b) is so small as to be acceptable.  Zone 2 diesel engine and zone 2 diesel generators are designed to reduce the risk of an engine being the source of ignition. Potential ignition sources on unprotected diesel engines include electrical, mechanical or static sparks, overspeed or ame transmission
