Remote Radiator Solutions For Rolls-Royce Power Systems (MTU Engines)
Remote radiators are a critical cooling solution for Rolls-Royce Power Systems (MTU) engines used in power generation, marine, and industrial applications. When engine rooms have space limitations, high ambient temperatures, or strict noise and ventilation requirements, remote-mounted radiators provide a flexible and reliable alternative to engine-mounted cooling systems.
Designed to meet the demanding thermal performance of MTU engines, remote radiators ensure stable engine operation, long service life, and compliance with project-specific environmental and mechanical conditions.
Typical Design Parameters
A remote radiator for MTU engines is engineered strictly according to project-specific operating conditions. Typical design inputs include:
Ambient temperature (design): up to 32 °C or higher
Maximum ambient temperature: up to 35 °C
Heat rejection (100% load): >5,000 kW system thermal load
Radiator design heat load: sized with safety margin
Coolant inlet / outlet temperature: e.g. 32 °C → 37 °C
Working pressure: ~5.5 barg
Test pressure: ≥12 barg
Design margin: minimum 10% cooling capacity margin
These parameters ensure reliable cooling under full load, continuous operation, and harsh environmental conditions.
