Perkins 4006-23TAG2A Genset Engine – 750–825 kVA

The Perkins 4006-23TAG2A is a 22.921-litre, six-cylinder diesel engine for generator sets rated up to 750 kVA prime and 825 kVA standby. It belongs to the Perkins 4000 Series, a heavy-duty power-generation platform covering 6-, 8-, 12- and 16-cylinder engine configurations.

A defining feature of this model is that the published generator ratings remain 750 kVA prime and 825 kVA standby at both 1500 rpm and 1800 rpm. The engine power values, frequency configuration and Build List still differ by rated speed, so the 50 Hz and 60 Hz versions must be identified separately before an engine replacement or genset project is approved.

Same Generator Rating, Different Speed Configuration

The 4006-23TAG2A can be supplied for 1500 rpm / 50 Hz and 1800 rpm / 60 Hz generator systems. Both versions are listed at the same generator-output ratings, but their gross and net engine powers are not identical.

Why Matching kVA Does Not Make the Versions Interchangeable

The 1500 rpm and 1800 rpm versions require different generator frequencies, engine settings and supporting genset configurations. An existing 50 Hz installation should not be converted to 60 Hz, or vice versa, only because both versions publish the same 750/825 kVA output.

Before approving a replacement, confirm the rated speed, original Build List, complete Engine Serial Number, alternator, control system, radiator arrangement and generator-set manufacturer.

Continuous, Prime and Standby Duty at 1500 rpm

The supplied product information identifies three operating levels for the 1500 rpm / 50 Hz configuration. Each rating describes a different duty and should be matched to the expected annual operating pattern.

A project intended for regular operation should not be sized only from the 825 kVA standby figure. The required duty, expected load profile and operating hours should be defined before the engine and alternator are selected.

Cooling Configuration Is Part of the Engine Specification

The 4006-23TAG2A is listed with temperate and tropical cooling configurations. The supplied information states that the cooling system can be configured for ambient temperatures up to 50°C, but the applicable cooling package must be confirmed against the exact Build List.

A tropical radiator should not be assumed from the engine model name alone. The quotation and nameplate information should identify which cooling configuration is included.

4000 Series Mechanical Platform

With a displacement of 22.921 litres and a dry weight of 2524 kg, the 4006-23TAG2A is a large industrial engine package. Foundation loading, lifting equipment, enclosure dimensions and maintenance access should be reviewed early in the genset design.

Cylinder-Head and Fuel-System Design

Each cylinder uses an individual four-valve cylinder head. The separate heads support gas flow and allow cylinder-level service work without treating the complete cylinder bank as one head assembly.

Unit fuel injectors are used for fuel atomisation and controlled combustion. Injector selection, calibration and replacement should be confirmed from the Build List and complete ESN rather than from the 4006-23TAG2A model name alone.

Shared 4000 Series Components

The 4000 Series uses shared component principles across several engine sizes, which can reduce the number of spare-part families required by fleet operators. This does not mean that parts are universally interchangeable between 4006, 4008, 4012 and 4016 engines. Every component must still be matched to the individual engine record.

Build Lists DGBF8527 and DGBF1002

The principal version in the supplied page uses Build Lists DGBF8527 and DGBF1002. DGB8527 and DGB1002 are the updated shortened designations used for engines from later production batches.

The supplied information treats the original and updated designations as the same stated engine specification with identical parts compatibility. The complete ESN is still required because it identifies the production record of the individual engine.

Information to Record from the Nameplate

• Complete engine model: 4006-23TAG2A
• Build List beginning with DGB or DGBF
• Complete Engine Serial Number
• Rated speed: 1500 rpm or 1800 rpm
• Original generator-set manufacturer and model
• Cooling configuration when known

The engine nameplate is normally mounted on the rocker-cover or timing-case area. A clear photograph of the complete plate is recommended because manually copied serial numbers are easily entered incorrectly.

Different 4006-23TAG2A Build Versions

The model name covers several E/U and E/P versions with different speed, regional and emissions designations. The Build List should therefore be treated as part of the product name during quotation and parts identification.

Ratings from one Build List should not be transferred to another version without supporting Perkins documentation. Regional, speed and emissions-specific builds may have different equipment or calibration even when the base model name is the same.

TA Luft Emissions Identification

The supplied content lists gaseous emissions to the 1/2 TA Luft (1986) standard among the model’s design features and separately identifies DGBF8460 as a 1500 rpm TA LUFT version.

Emissions compliance should therefore be quoted against the exact Build List and its supporting documentation. The 4006-23TAG2A model name alone should not be used as proof that every regional version carries the same emissions approval.

Comparing the TAG2A and TAG3A

The Perkins 4006-23TAG3A shares the six-cylinder, 22.921-litre 4006 platform but occupies a different published output position. The applicable rating, Build List, cooling package and application limits should be compared using the official data for each engine.

A TAG3A should not be proposed as a direct TAG2A replacement solely because the dimensions or base architecture appear similar. Alternator matching, coupling, radiator, exhaust, fuel settings and control integration must be reviewed.

Fuel Consumption at 1500 rpm

The supplied fuel-consumption values are stated in litres per hour for the 1500 rpm configuration. They correspond to different duties and load points and should not be compared without considering the delivered output at each point.

Actual consumption depends on fuel properties, site conditions, alternator efficiency, engine condition and the load profile of the complete generator set. These values should be used as rating references rather than guaranteed site-consumption figures.

Maintenance Baseline

The stated standard oil-change interval is 500 operating hours under standard conditions. A shorter interval may be required for severe loads, high dust levels, poor fuel quality, prolonged low-load operation or abnormal oil-analysis results.

Original Perkins Replacement Parts

The following references are listed as original Perkins components. The supplied page states full parts availability for the DGB/DGBF8527 Build List family. Other versions should be checked separately. Additional Perkins engine parts can be reviewed by component category.

Several components have more than one listed reference. Do not select an alternative by appearance or dimensions alone. Build List and ESN verification is required before the final part number and quantity are released.

Parallel Generator Operation

Generator sets using the 4006-23TAG2A can operate in parallel when the complete units have compatible controllers, alternators, voltage regulators, synchronization equipment, protection settings and load-sharing functions.

Parallel capability is a property of the complete generator system, not of the engine model alone. The operating sequence and maximum permitted load steps should be reviewed before commissioning.

Procurement and Export Release

Availability should be confirmed when the inquiry is submitted. The stated lead time is typically 3–4 weeks, while quotations are provided within 24 hours after the engine configuration, quantity and delivery terms have been defined.
