NRF 30358 Intercooler

Overview of the NRF 30358 Intercooler

The NRF 30358 Intercooler is a high‑performance, air‑cooled charge‑air cooler designed to optimize engine efficiency and power output in turbocharged diesel engines. It is engineered for use in a wide range of commercial vehicles, including the Opel Movano B, Renault Master III, and various Vauxhall models.

Key Design Features

Air‑Cooled Architecture

The intercooler employs a robust air‑cooled design, featuring a compact yet efficient heat exchanger that dissipates exhaust gas temperature before it reaches the turbocharger. This reduces compressor surge and improves overall engine reliability.

Durable Construction

• High‑strength aluminum alloy fins provide excellent thermal conductivity while maintaining a lightweight profile.
• The housing is fabricated from stainless steel, ensuring resistance to corrosion in harsh operating environments.
• All components are sealed with high‑temperature gaskets, guaranteeing long service life even under extreme pressure conditions.

Optimized Flow Path

The internal geometry of the NRF 30358 is engineered for minimal flow restriction. The cross‑sectional area and fin spacing are calibrated to maintain optimal airflow, thereby reducing backpressure and preserving turbocharger efficiency.

Compatibility and Applications

This intercooler is specifically tailored for the following engine families:

• Opel Movano B 2.3 CDTI – models from 2010 onward.
• Renault Master III 2.3 dCi – various power outputs (110, 125, 150, 180 kW).
• Vauxhall Movano B 2.3 CDTI – including both front‑wheel and rear‑wheel drive variants.
• Other OEMs such as Nissan, Volkswagen, and Ford have compatible engine blocks that accept the NRF 30358 with minor modifications.

Installation Highlights

The NRF 30358 is designed for straightforward installation:

• Standard mounting brackets are included, allowing a direct swap from OEM intercoolers without additional hardware.
• The unit fits within the existing engine bay clearance, preserving air intake routing.
• All necessary fittings (air hoses, coolant lines) are supplied in the package, ensuring a complete, ready‑to‑install solution.

Performance Benefits

• Reduced Intake Air Temperature (IAT): By cooling the charge air to lower temperatures, the intercooler increases air density, leading to higher combustion efficiency.
• Enhanced Power Output: Users report up to a 5% increase in horsepower and torque when replacing stock intercoolers with the NRF 30358.
• Improved Fuel Economy: Cooler intake air allows for more precise fuel metering, reducing fuel consumption by approximately 1–2% under typical operating conditions.
• Extended Engine Life: Lower combustion temperatures reduce thermal stress on engine components, contributing to longer service intervals.

Maintenance and Longevity

The NRF 30358 is engineered for low maintenance:

• All internal surfaces are anti‑corrosion coated, eliminating the need for regular cleaning.
• Routine checks involve inspecting air hoses for leaks and verifying that coolant flow remains unobstructed.
• Under normal operating conditions, the intercooler can function reliably for over 200,000 kilometers without replacement.

Technical Specifications

Conclusion

The NRF 30358 Intercooler delivers superior thermal management for turbocharged diesel engines, providing tangible gains in power, efficiency, and durability. Its robust construction, precise airflow design, and ease of installation make it a preferred choice for fleet operators and performance enthusiasts alike.
