Caterpillar Inc. has introduced six new 50-Hz standby ratings that provide power density while helping to reduce overall site preparation, transportation, installation and maintenance costs.

Caterpillar now offers the Cat 3516E diesel generator set with the following 50-Hz standby power ratings and emissions thresholds:

  • three ranging from 3,000 kVA to 3,500 kVA that provide certification to U.S. EPA Tier 2 emissions standards;
  • two from 3,000 kVA to 3,250 kVA that offer nitrogen oxide (NOx) emissions under 2,000 mg/Nm3; and
  • one low-NOx 3,500 kVA rating for regulated environments and applications.

The Cat 3516E diesel generator set with the 3,500 kVA rating provides an 8,800-kg (19,400-lb) weight reduction over a comparable product offering the same power output, while occupying up to 15 per cent less floor space. The launch of these new power ratings allows Caterpillar to offer diesel generator sets with power densities ranging from 850 kVA to 3,500 kVA.

Cat 3516E generator sets are designed to meet the NFPA power restoration requirement for Level 1 systems and accept 100 per cent block load in one step. They meet ISO 8528-5 G3 requirements for steady state and load acceptance.

The new power ratings are available with a low-, medium- or high-voltage frame alternator that enables quick load acceptance through exceptional motor starting capabilities. This feature eliminates the need to oversize the generator set due to motor starting requirements.

The Cat 3516E generator set uses the Cat ADEM™ A5 engine control module (ECM). This module seamlessly integrates all engine functions including ignition, governing and air-fuel ratio control for optimal performance while protecting the engine.
