Overview

The 3512 diesel generator sets have been developed to meet your mission critical, continuous, standby and prime applications. Producing reliable power from 1000 to 1400 kVA at 50 Hz, each generator set is designed to meet ISO 8528-5 transient response requirements and accept 100 percent rated load in one step. And each is designed for low fuel consumption reducing operating costs. Our integrated control system, including Cat® UPS, ATS and switchgear, secure your power supply and keep you connected to your fleet through on-site and remote monitoring options. The EMCP4 control panel provides a flexible control platform, with an easy-to-use display — it's your single source for management and diagnostics tools. The EMCP 4.4 controller provides multi-generator set paralleling capability, giving you the ability to add generator sets to match your growing power requirements. It's not just quality that matters but customization, choose from a broad range of accessories and bolt-on system expansion attachments. Discover our flexible packaging options to work with your spatial restrictions and environmental conditions. Our 3512 generator sets are developed for such prerequisites, so that you can meet your specific power needs.

Cat Diesel Engine

The four cycle Cat diesel engine combines consistent performance with excellent fuel economy and transient response that meets or exceeds ISO 8528-5. The engines have been designed and built for a wide range of applications and can be optimized for low fuel consumption or low emissions. The engines feature a reliable, rugged, and durable design that has been field proven in thousands of applications worldwide from emergency standby installations to continuously operating power plants.

Generators

The generators used on Cat packages have been designed and tested to work with the Cat engine. The generators are built with robust Class H insulation and provide industry leading motor starting capability. Random wound generators provide good generator performance in a majority of applications and form wound is available for harsh mechanical and electrical environments.

Cat EMCP Control Panel

The EMCP controller features the reliability and durability you have come to expect from your Cat equipment. EMCP4 is a scalable control platform designed to ensure reliable generator set operation, providing extensive information about power output and engine operation. EMCP4 systems can be further customized to meet your needs through programming and expansion modules.

Cooling System

The cooling system has been designed to operate in standard ambient temperatures up to 50°C (122°F), with optional high ambient radiators available. The factory installed cooling system has been designed and tested to ensure proper generator set cooling, and includes the radiator, fan, belts, and all guarding installed as standard. Contact your Cat Dealer for specific ambient and altitude capabilities.

World Wide Product Support

Cat Dealers provide extensive post sale support including maintenance and repair agreements. Cat dealers have over 1,800 dealer branch stores operating in 200 countries.
