4012 TESI Spark Ignited Gas Engine

< Back

Overview

The 4012TESI is a 46 litre, 12 cylinder, spark ignited gas engine. It’s supplied both as an Electro Unit for power generation and as a Cogen Unit for combined heat and power (CHP) applications. One of the engines in the Perkins 4000 Series, the 4012TESI delivers 600-632 kWm (576-600 kVA). Variants of the 4012TESI are designed to meet TA Luft or 1/2 TA Luft emission standards. Low compression variants of the engine are specifically designed to run on low-methane gases, such as those derived from landfill sites. In keeping with all Perkins gas engines, end users and Original Equipment Manufacturers (OEMs) can enjoy full support from our global network of 4000 Series Gas Centres of Excellence.

Economic power

In common with all Perkins gas engines, the 4012TESI features competitive engine and parts pricing, 500 hour service intervals and low fuel consumption ensuring significant owner savings.

Commonality of components with other engines in the 4000 Series means you can reduce stocking and inventory levels.

Efficient power

Designed for maximum thermal efficiency, the 4012TESI is compact with a high power to weight ratio.

Reliable power

The 4012TESI is built on Perkins proven durability. It comes with a high level of serviceability and ease of maintenance – all backed up by our global network of Perkins 4000 Series Gas Centres of Excellence (COEs). Located in key territories across the world, the COEs have invested in ensuring they have the expertise you need, enabling them to fully support end users and OEMs. They give you product and service support and can work with you to customise engines to suit your needs.

Tailored to your needs

The 4012TESI engine can be tailored to meet your specific installation needs and supplied as a gas Electro Unit for power generation or as a Cogen Unit for combined heat and power schemes.

Within the 4012 range are variants with high and low compression. The engine can be run on a variety of gases, with low compression variants designed to run on low-methane gases, such as bio-gases derived from landfill sites.
