OEM remanufactured Mattei e-compressors for Optare applications

Mattei_MC65_E_Compressor

Imperial Engineering has added OEM remanufactured Mattei electric air compressors to its range of compressors, service kits and upgrades for hybrid and electric buses equipped with electric compressors.

Suitable for Optare MetroCity EV buses, the OEM remanufactured option provides a saving of around 20% against the cost of a brand new OEM replacement unit without compromising on quality or performance.

While diesel buses use engine-driven air compressors, hybrids and EVs are fitted with separate electrically-driven screw or vane compressors. Known as ‘e-compressors’, these systems comprise of a compressor, electric drive motor and inverter.

Unlike diesel engine-driven compressors that are cooled and lubricated by the engine, e-compressors have a standalone system. Also, unlike conventional compressors which are supplied with air from the engine filter, e-compressors have a built-in air filter. Both systems require regular maintenance to ensure intended service life.

Contributors to e-compressor failure include excessive oil carry resulting in oil leaks and dirt ingress into the drive motor causing bearing damage. This leads to overheating and is the primary cause of component failure. With this in mind, Imperial Engineering also offers an OEM cooling upgrade for Mattei e-compressors, enabling operators to preserve the service life of systems fitted to existing Optare electric buses within their fleets.

Imperial Engineering offers a range of service kits, upgrades and replacement assemblies for all e-compressor OEMs including Mattei, Gardner Denver Hydrovane and Knorr-Bremse. Bus manufacturers, including ADL, BYD, Caetano, Optare, Volvo, Yutong and Wrightbus use e-compressors on their vehicles and Imperial Engineering is pleased to support operators with technical advice and guidance.
