Expansion tanks

An expansion tank is an important part of an engine cooling system. Along with the temperature change in the system, the pressure in the system changes. This causes the refrigerant itself to expand. The expansion tank protects the system against overpressure and collects the excess liquid. NRF expansion tanks are produced with 100% new materials. After the production process, each expansion tank is subjected to a leak test, pressure test (up to 6 bar) and vibration test. All expansion tanks are validated to ensure perfect fitment in the vehicle.
