Innovative and Reliable:
Introducing A4GEN® Alternators by ALLFORGEN CO. LTD

Together with major generator manufacturers, ALLFORGEN CO. LTD. developed its own specification and began producing modern, reliable, and competitive A4GEN® generators. The agreement signed with an experienced and renowned production center in China guarantees quality and reliability, as well as meeting all requirements for safety standards and CE marking. The A4GEN® generator line includes the most popular power ranges and is easy to fit to installation requirements according to European standards.

Tailored to Each Installation:
A4GEN® Offers a Full Range of Power and Additional Options

The A4GEN® generator line offers cost-effective options in the power range from 16 kW (20 kVA) to 1200 kW (1500 kVA). For more demanding applications, the A4GEN® series can be enhanced with additional equipment such as PMG, AVR for parallel operation, anti-condensation heaters, or a set of PT100 temperature sensors. The central warehouse in Poland ensures wide availability of the most popular models and short delivery times. All generators undergo rigorous tests and are subject to continuous production quality control. A4GEN® generators are covered by a 2-year manufacturer’s warranty.

We rely exclusively on materials whose quality speaks for itself.

Latest news

A4GEN alternators certified for grid compliance under NC RfG standard

 A4GEN alternators become well accepted option by genset builders. Recently, generating set with A4GEN generators were tested and certified to the “grid code” according to the NC RfG standard. The collaboration with grid is quite important feature for some applications. Not only parallel operation in isolated power plants but synchronization with local grid is vital part in advanced projects. Although the alternator itself does not need to be certified but should deliver the right performance and meet the requirements for the entire generating set test. Tests done for the ready gensets with A4GEN alternators were carried by the independent laboratory and ended with certificate of conformity.

New XAW feature for A4GEN alternators delivers 300% short-circuit current without PMG

Together with the production center in China we are introducing the new feature to the A4GEN alternators. XAW – it is Extra Auxiliary Winding to be available now as the new option for the whole range of the A4GEN alternators. This solution allows to archives shortcut of 300% nominal current on minimum 10s period without need of PMG installing. Up to now it was possible only with PMG option.

This solution has many advantages over the classic PMG. Please see below brief CONS/PROS table:
