VEMO V46-61-0011 Heating

VEMO V46‑61‑0011 Interior Heating Heat Exchanger

The VEMO V46‑61‑0011 is a high‑performance heat exchanger designed specifically for vehicle interior heating systems. It delivers reliable warmth to the cabin by extracting heat from the engine coolant and transferring it efficiently to the air that circulates inside the vehicle.

Key Design Features

• Compact Dimensions: Measuring 180 mm in length, 157 mm in width, and 42 mm in height, the unit fits seamlessly into tight engine bay spaces without compromising airflow or component clearance.
• Robust Construction: Made from premium aluminium alloy with a corrosion‑resistant coating, it withstands high temperatures and harsh automotive environments for extended service life.
• Optimised Flow Path: The internal finned structure maximises heat transfer while minimising pressure drop, ensuring that the cabin receives consistent warmth even at low engine speeds.
• Easy Installation: Designed with standard mounting brackets and a quick‑connect hose system, it can be swapped into existing heating assemblies without major modifications.

Compatibility Overview

The VEMO V46‑61‑0011 is engineered to fit a wide range of commercial and passenger vehicles. Its universal design allows integration with:

• Nissan Primastar, Opel Vivaro, and Renault Trafic series vans.
• Opel Movano and Vauxhall commercial models.
Various engine configurations including diesel and petrol, with coolant temperatures ranging from 80 °C to 95 °C.

Performance Characteristics

The heat exchanger achieves a thermal efficiency of up to 90 %, meaning that most of the available engine heat is captured and redirected into the cabin. Its low pressure drop (0.15 bar) ensures that the vehicle’s cooling system remains unaffected, preserving optimal engine operation.

Installation Procedure

1. Disconnect the existing heating unit: Remove hoses and mounting brackets carefully to avoid coolant spillage.
2. Mount the VEMO V46‑61‑0011: Secure it with the supplied brackets, aligning the inlet and outlet ports with the vehicle’s coolant lines.
3. Connect the air ducting: Attach the cabin air intake to the exchanger’s outlet, ensuring a tight seal to prevent leaks.
4. Prime the system: Refill the cooling circuit with fresh coolant and bleed any trapped air.
5. Test operation: Start the engine and verify that cabin temperature rises smoothly while monitoring for any abnormal pressure or temperature readings.

Benefits to Vehicle Operators

• Improved Passenger Comfort: Rapid heat delivery keeps occupants warm during cold starts and in low‑ambient temperatures.
• Fuel Efficiency: By utilizing waste engine heat, the unit reduces reliance on auxiliary heating elements that draw power from the battery or alternator.
• Reduced Maintenance: The durable aluminium construction resists corrosion, lowering long‑term servicing costs.
• Versatility: Its universal fitment means fleet operators can standardise on a single component across multiple vehicle models.

Technical Specifications Summary

Conclusion

The VEMO V46‑61‑0011 interior heating heat exchanger represents a blend of engineering precision and practical design. Its compact size, high efficiency, and broad compatibility make it an ideal choice for fleet managers and vehicle owners seeking dependable cabin warmth without compromising engine performance or incurring excessive maintenance costs.
