Thornycroft – NEW Thornycroft TRGS-25 24kVA Single Phase Marine Generator Set

Thornycroft TRGS-25 24kVA Marine Generator – Professional Overview

The Thornycroft TRGS-25 is a new single-phase marine generator set designed for vessels requiring a dedicated onboard electrical power source.

The package uses a four-cylinder, 2.45L diesel engine with heat exchanger cooling and a wet exhaust system. It is matched with a MeccAlte alternator and Deep Sea control panel.

The standard configuration operates at 1500 RPM and 50Hz, while a 60Hz configuration operating at 1800 RPM is available when required.

Generator Output and Electrical Performance

The TRGS-25 is rated at 24kVA continuous and 26kVA intermittent.

This distinction is important when assessing the generator against a vessel’s electrical demand. Continuous output represents the specified ongoing operating capacity, while the intermittent rating provides additional capacity for appropriate temporary operating requirements.

The generator is configured for single-phase electrical output.

Diesel Engine and Cooling System

The generator uses a four-cylinder diesel engine with 2.45L cylinder capacity.

The engine is heat exchanger cooled, providing the specified marine cooling configuration for the generator set.

It also uses a wet exhaust system, which forms part of the complete marine installation arrangement.

MeccAlte Alternator

The TRGS-25 is equipped with a MeccAlte alternator.

The alternator forms the electrical generation component of the package and is matched to the generator’s stated 24kVA continuous output.

For vessel integration, the generator’s electrical specifications should be checked against the onboard distribution system and connected equipment.

Deep Sea Control System

A Deep Sea control panel is included with the generator set.

The package also includes a 10M extension harness, allowing the control panel to be remotely mounted where the vessel’s installation requires the operator controls to be positioned away from the generator.

This configuration provides flexibility when planning the generator room and remote control location.

Engine Protection and Emergency Shutdown

The TRGS-25 incorporates an emergency stop on the engine together with a self-protecting automatic shutdown system.

These features form part of the generator’s control and protection arrangement, helping the system respond automatically to specified engine protection conditions.

The exact protection parameters and installation requirements should be confirmed against the supplied control system documentation.

50Hz and 60Hz Configurations

The standard generator configuration is specified at 1500 RPM and 50Hz.

A 60Hz configuration at 1800 RPM is also available when required.

This option is particularly relevant when specifying a generator for a vessel with electrical equipment designed around a different frequency. The required frequency should therefore be confirmed before the generator is ordered.

Marine Installation and Applications

The Thornycroft TRGS-25 24kVA Marine Generator Set is suited to marine applications requiring substantial single-phase electrical generation.

Its combination of diesel propulsion for the generator, MeccAlte alternator, heat exchanger cooling, wet exhaust, remote control capability, and automatic engine protection creates a complete generator-set configuration for suitable vessels.

Installation should account for generator location, exhaust routing, cooling connections, electrical integration, remote control positioning, and service access.

Why the Thornycroft TRGS-25 Stands Out

The TRGS-25 24kVA Marine Generator Set brings together several important marine-generator features in one package.

Its 24kVA continuous rating, four-cylinder diesel engine, MeccAlte alternator, Deep Sea control panel, 10M remote harness, wet exhaust, and automatic shutdown system provide a clearly specified configuration for professional marine power requirements.

The availability of a 60Hz/1800 RPM configuration also gives buyers additional flexibility when specifying the generator for their vessel’s electrical system.

Who This Generator Set Is Best For

The TRGS-25 is suited to boat owners, commercial vessel operators, marine engineers, boatbuilders, and repower specialists requiring a single-phase diesel generator with a 24kVA continuous rating.

It is particularly relevant to vessels whose electrical requirements call for a generator in the 24kVA class and whose installation can accommodate its four-cylinder diesel configuration.

Before ordering, buyers should confirm the required electrical frequency, output, cooling arrangement, exhaust configuration, control-panel location, and available installation space.
