Jenbacher J420E enclosed generator packages
The J420E offer comprises 60 available immediately; 117 on the way, with new, sound-attenuated packages specified at nominal 1.5 MW each, 50 Hz and 400/231 V. Availability requires written reconfirmation and is subject to prior sale. Incoming arrival dates, allocation and delivery terms are confirmed with the offer.
The seller describes a generator breaker and connection point within the package scope. That does not establish that site cabling, a step-up transformer, paralleling switchgear, emissions treatment or installation are included. J&J will request a clear equipment schedule and commercial offer for the selected units.
Specify the complete operating requirement
A matching MW figure is only the first check. The proposed package also needs to suit the fuel, site, duty and electrical system. Ask for output at your operating conditions and identify whether the stated rating is gross or net of auxiliary loads.
| Requirement | Send with your inquiry |
|---|---|
| Power and duty | Required net kW or MW, load profile, operating hours, redundancy and any load-step requirements. |
| Electrical connection | Hz, voltage, phase, neutral arrangement, islanded or utility-parallel operation and the project one-line. |
| Gas supply | Fuel analysis, supply pressure, available flow and any limits on delivery or treatment. |
| Site | Ambient conditions, elevation, project location, enclosure needs and applicable emissions requirements. |
| Delivery | First required delivery, total units and phases, included equipment and acceptance milestones. |
Need 60 Hz? Identify it before selecting units
The listed J420E offer is specified at 50 Hz. A step-up transformer changes voltage, not frequency. A proposed conversion needs its own engineering approval, equipment changes, output basis and warranty terms. J&J can also receive requests for a separately specified 60 Hz package.
Coordinate the generator with transformers and switchgear
For multi-unit installations, define the generator connection boundary and the equipment beyond it. Share the one-line so generator offers, step-up transformer requirements and switchgear requirements can be compared on the same project basis.
Identify responsibility for controls, synchronization, protection, metering, cooling, exhaust, fuel handling, site construction and commissioning. A supply inquiry does not substitute for the project's engineering, permitting or utility acceptance process.
Request a natural-gas generator offer
Email your MW, Hz, voltage, quantity, duty, location and needed-on-site date to Tommy Marco at J&J Transformers. For the published package, include listing ID JJ-J420-MULTI. Current availability, specifications, price, freight and included scope are confirmed in writing.
Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
Does J&J sell natural-gas generators?
Yes. J&J buys, sells and sources natural-gas generator packages, including the published Jenbacher J420E multi-unit offer. Contact J&J for current availability and a written offer.
Is the published Jenbacher J420E offer 50 Hz or 60 Hz?
The written seller specification states 50 Hz and 400/231 V. A 60 Hz requirement needs a separately confirmed configuration or an approved conversion scope.
Can I buy several units for one power project?
J&J confirmed 60 Jenbacher J420E units available immediately and 117 on the way on September 21, 2026. Send your total quantity and delivery phases. Availability requires written reconfirmation and is subject to prior sale. Incoming arrival dates, allocation and delivery terms are confirmed with the offer.
Is emissions equipment included?
Do not assume it is. The J420E seller describes SCR as an optional addition quoted for project requirements. Confirm the included treatment and site suitability in writing.
