800 kW DMT Corporation DMT-825C Diesel Generator

Engine: Cummins KTA38 | Rating: 800 kW / 1000 kVA | Type: Stationary Standby

Professional Overview

The DMT-825C is a heavy-duty industrial power generation set engineered by DMT Corporation, utilizing the legendary Cummins KTA38 engine platform. This combination is widely regarded as one of the most reliable "workhorse" configurations in the world, commonly used for hospital backup, data centers, and heavy industrial prime power. The KTA38 is a V-12, twin-turbocharged engine known for its massive displacement and ability to handle high-step load blocks with minimal frequency deviation.

Technical Specifications

• Standby Rating: 800 kW / 1000 kVA (at 0.8 power factor).
• Engine: Cummins KTA38-G2 (V-12, 4-stroke, Twin Turbocharged).
• Alternator: Typically equipped with a Marathon or Stamford brushless permanent magnet generator (PMG) for superior motor starting.
• Voltage: Multi-tap/Reconfigurable (Commonly 277/480V or 120/208V, 3-Phase).
• Frequency: 60 Hz (Standard US) or 50 Hz (International).
• Cooling: Unit-mounted radiator (Standard) or heat exchanger cooled.
• Governing: Electronic isochronous (ensures ±0.25% frequency stability).

Key Performance Features

• Cummins KTA38 Reliability: The KTA38 engine is famous for its "built-to-last" design, featuring individual four-valve cylinder heads for better heat dissipation and a robust fuel system that handles varying fuel qualities effectively.
• High Step-Load Capability: Designed to meet NFPA 110 requirements, this unit can accept a 100% block load in a single step, which is critical for emergency life-safety systems.
• Ease of Service: Unlike newer Tier 4 Final engines that require complex after-treatment (DEF/DPF), the KTA38 (depending on the year) is often favored in the used market for its mechanical simplicity and the universal availability of parts.
• Heavy Duty Frame: DMT Corporation builds these units on a structural steel skid with integrated vibration isolation, significantly reducing noise and structural wear.
