Caterpillar Launches Cat 3512C Diesel Generator Set with Improved Power Density for Standby Applications

Cat3512CCaterpillar Inc. has released a new standby power node for the Cat 3512C diesel generator set that offers industry-leading power density.  Rated at 1,750 kW for 60 Hz standby applications, the Cat 3512C generator set offers reliable backup power from an optimally sized engine and a reduced overall footprint that delivers numerous benefits, including lower overall site preparation, transportation, installation and maintenance costs, as well as reduced fuel consumption and lower emissions.

The Cat 3512C diesel generator set is the latest in a series of new ratings for proven standby power solutions from Caterpillar.  These generator sets have been re-engineered with the higher power densities requested by customers to meet increasingly challenging restrictions on capital, site size, and cost. Over the next six months, Caterpillar will offer seven new ratings based on existing, proven platforms that deliver the benefits of high power density to our customers around the globe.  The full line will feature power nodes ranging from 1,250 kW to 2,800 kW that can significantly reduce customer’s installed costs over current product offerings.

“Maximizing the return on investment for standby power requires customers to specify a solution that is precisely sized to balance power availability and reliability with lower costs,” said Lenaik Andrieux, general manager for Caterpillar’s Large Electric Power Division.  “These standby generator sets with improved power densities will allow customers to fine-tune the selection of the power they need through a compact package that can significantly reduce their costs for both the short and long term.”

The Cat 3512C generator set has a highly competitive footprint of 151.56 square feet, saving up to 13 percent of installed space when compared with competing generator sets at the same rating. It is designed to meet the NFPA power restoration requirement for Level 1 systems and accept 100 percent block load in one step.  The Cat 3512C generator set also meets ISO 8528-5 G3 requirements for steady state and load acceptance.  It can be configured to meet the US EPA Emergency Regulations.

The Cat 3512C generator set can be equipped with a low- or high-voltage frame alternator that enables quick load acceptance through exceptional motor starting capabilities.  This feature allows users to minimize oversizing the generator set due to motor starting requirements.

The Cat 3512C generator set utilizes the field-proven Cat ADEM A3 engine control module (ECM), which integrates all engine functions including ignition, governing, air-fuel ratio control, and engine protection.
