Serck Heat Exchange Mark III Charge Air Cooler CAC for a Cummins QSK19 Engine
Serck Heat Exchange Coleshill Cummins TFL Traction Cooler
I e-mailed Serck Heat Exchange for information as I could only identify it as possibly being a traction cooler from looking at the serckheatexchange.co.uk website.
Serck e-mailed me back informing me that it was in fact a mk3 charge air cooler for the Cummins QSK19 engine. Also, that Serck had manufactured it as part of a refurbishment contract with Cummins that was coming to an end.
