High and Low Temperature Remote Radiator for MTU Gas Generator Distributor

High and Low Temperature Remote Radiator for MTU Gas Generator Distributor

High and low temperature dual circuit integration:

High-temperature circuit: cooling gas engine block, exhaust system and turbocharger and other high-temperature components (temperature usually ≥ 100 ℃), the medium is mostly glycol aqueous solution or special coolant.

Low-temperature circuit: cooling of generator windings, control modules, lubrication oil systems, etc. (temperature of about 40-80 ℃), the medium can be air, mineral oil or low-viscosity coolant.

Remote installation design:

The radiator is separated from the main body of the gas generator and connected remotely through the piping system, which avoids the influence of high temperature and vibration on the radiator at the site of the generator, and at the same time facilitates the centralized heat dissipation management.

Application Scenarios and Fields

1. Industrial backup power and distributed energy

Data centers and critical facilities:

Cooling the engine block and generator stator of large gas generators (e.g., above 2000kVA), the remote radiator can be installed outdoors or in a separate machine room to avoid excessive indoor heat load (e.g., standby power systems in financial data centers).

Petrochemical & Manufacturing:

Used for heat dissipation of gas turbine-driven compressors and pumping units. Remote design prevents heat dissipation risks in explosive gas environments (e.g. oil refineries, natural gas processing stations).

2. Cogeneration and district energy systems

Integrated energy stations for buildings:

Integrated in a gas generator - waste heat boiler combined system, the high temperature loop cools the engine and the low temperature loop recovers some of the heat for preheating fuel or domestic hot water, improving system energy efficiency (e.g., CCHP in commercial complexes).

Microgrids in remote areas:

Remote radiators can be installed near water sources, using water cooling to improve cooling efficiency, applicable to field power stations without centralized cooling facilities (e.g., oilfields, mining captive power plants).

3. Transportation and Mobile Power

Ship and marine engineering:

Cooling ship gas generators (e.g. LNG-powered ships), remote radiators are installed on the deck or outside of the nacelle to avoid seawater corrosion and nacelle space limitations (e.g. emergency power supply for ocean-going freighters).

Mobile power generators:

High and low temperature integrated design reduces the volume of heat dissipation system, and the remote radiator can be arranged at the rear or roof to reduce the center of gravity of the whole vehicle (e.g. emergency power supply vehicle, field power supply vehicle).

4. Special environment and safety scenarios

Explosion-proof area:

The remote radiator keeps a safe distance from the main body of the gas generator, meets ATEX or UL explosion-proof standards, and is suitable for coal mines, chemical workshops and other flammable and explosive environments.

High Altitude and Extreme Climate:

Ensure normal operation in environments below - 40℃ (e.g. backup power supply for communication base stations in highland areas) through the anti-freezing design of remote radiators (e.g. electric tracer, glycol solution).

Case: A data center uses two 1.5MW gas generators, equipped with high and low temperature integrated remote radiators, with the high-temperature circuit cooling the engine (800kW) and the low-temperature circuit cooling the generator control module (150kW), and the remote radiators are mounted next to the outdoor cooling towers, which improves the energy efficiency of the system by 12% compared with the traditional integrated type.
