Perkins 4006-23TAG ElectropaK Diesel Engine

Overview

The Perkins 4006-23TAG is a six-cylinder, 23 litre diesel engine from the Perkins 4000 Series, built for prime and standby power generation. Perkins states that the 4006 range of ElectropaK engines and Electro Units delivers 750 to 900 kVA and can be supplied with or without radiator and air cleaner. Across its ratings the Perkins 4006-23TAG provides 531 to 886 kWm gross mechanical output and a typical electrical output of 595 to 1000 kVA (476 to 800 kWe) at 1500 or 1800 rpm.

Seven Star LLC supplies the Perkins 4006-23TAG to generator set builders, utilities, hospitals and industrial users across the Sultanate of Oman and the GCC. From our Muscat office we help with rating selection, cooling arrangements and the documents required for project approval and repower work.

Working Principle

The Perkins 4006-23TAG is a four-stroke, direct injection diesel. Each cylinder has its own four-valve cylinder head, which Perkins says gives optimised gas flows, and unit fuel injectors provide ultra-fine atomisation for controlled, rapid combustion. Intake air is compressed by turbochargers and cooled by an air-to-air charge cooler before entering the cylinders, which are designed around a compression ratio of 13.6:1.

Perkins reports that the engine is capable of meeting half TA Luft (1986) emission levels. The engine runs at constant speed to drive a generator at 50 or 60 Hz, and the published ratings include prime, standby and baseload duty, giving operators options from emergency backup to continuous power generation.

Engineering Design of the Perkins 4006-23TAG

The engine is an in-line six with a 160 mm bore and 190 mm stroke, giving a displacement of 23 litres. Cooling is by liquid, and rotation is anti-clockwise viewed from the flywheel end. Perkins highlights the exceptional power-to-weight ratio and compact design of the 4006 engines, which make them simpler to transport and install, and notes the commonality of components with other 4000 Series engines, which helps owners reduce spare parts holdings.

The published ElectropaK dimensions are about 2927 mm long, 1690 mm wide and 2125 mm high, with a dry weight of 2524 kg; final dimensions depend on the options chosen. Typical alternator efficiency is stated as 90 to 95 percent. Because the engine can be ordered with or without radiator and air cleaner, packagers can fit a remote cooling system where a plant room layout or high ambient temperature demands it.

Key Features

Below are the points that make the Perkins 4006-23TAG a common choice for large generator sets.

• Gross mechanical output of 531 to 886 kWm and typical electrical output of 595 to 1000 kVA.
• 50 Hz typical outputs of 746 to 802 kVA prime, 820 to 898 kVA standby and 595 to 637 kVA baseload.
• Individual four-valve cylinder heads for optimised gas flow.
• Unit fuel injectors for ultra-fine atomisation and controlled combustion.
• Turbocharged with air-to-air charge cooling and capable of half TA Luft (1986) emissions.
• Oil change service intervals of 500 hours as standard.
• Component commonality with other Perkins 4000 Series engines to simplify spare parts planning.
• Available as an ElectropaK with radiator and air cleaner or as an Electro Unit without them.

Industrial Applications

Perkins notes proven reliability for the 4006 in prime and standby installations across manufacturing facilities, hospitals and data centres. In Oman, gensets built on the Perkins 4006-23TAG protect hospitals, malls, hotels and government buildings in Muscat, and supply prime power for quarries, cement plants, remote camps and industrial estates in Sohar, Nizwa and Salalah.

Utilities and oil and gas contractors use the baseload ratings for small power stations and production support where the grid is distant. Owners of older 4006 sets can also plan repowering or overhaul with Perkins genuine parts. For smaller duties the Perkins 2506C-E15TAG2 diesel engine offers a lighter option, and generator controls such as the DSE7320 auto mains failure controller are commonly fitted to these sets. Seven Star LLC supplies the Perkins 4006-23TAG across Oman and the GCC.

Technical Specifications

The figures for the Perkins 4006-23TAG below come from the Perkins product page; final dimensions depend on selected options.

Warranty and Rating Definitions

Perkins describes a class-leading warranty for the 4006: for prime power, 12 months with unlimited hours, or two years up to 6,000 hours for engines operating fewer hours; for standby, three years or 1,500 hours, whichever comes first. Prime power allows unlimited hours at an average 80 percent load factor with a 10 percent overload, while standby is limited to 500 hours a year with no overload. Matching the Perkins 4006-23TAG rating to the real duty is essential to stay within these terms.

Product Support for the Perkins 4006-23TAG

Perkins backs the 4006 with a global support network of trained engine specialists, web-based tools for technical information and parts identification, and access to genuine Perkins parts throughout the life of the engine. Optional Perkins Platinum Protection extends cover beyond the standard warranty. For owners in Oman, Seven Star LLC helps coordinate genuine filters, gaskets and overhaul components for the Perkins 4006-23TAG, so that maintenance at 500-hour intervals can be planned in advance and engine availability stays high on standby and prime power sites alike.
