We have now been the supplier for Mobile A/C Tuition and Assessment for the 7543 Qualification for Nottingham City Transport for many years.

NCT are a company that like to keep their technicians up to date with all current legislations and make sure they are qualified to carry out servicing work with competence. All of the NCT technicians during recent years been trained and assessed for the Mobile A/C qualification by using their semi automatic mobile A/C service station for carrying out their R134A servicing work. They have recently taken delivery of forty new buses with another fifteen placed on order for 2015 and the question was asked “how do we carry out servicing the A/C on these vehicles, as they contain the refrigerant known as R407C”. This refrigerant is quite unusual to be used as a mobile A/C refrigerant. R134a is currently under phase out and will not be installed into new mobile A/C from January 2017 and the chosen replacement is R1234yf. R407c is a Zeotropic blend which means it cannot be charged at vapour state because of the characteristics of the blend. During 2014 our company discussed in length the differences of this application and servicing equipment required when the vehicle warranty expires– it would need a tooling replacement as the stand alone A/C service station cannot be used to carry out such work. NCT have purchased a complete new set of highly professional tools to work on the R407C buses and have had all their staff bespoke trained to give competence and confidence to their company. We are proud to have been part of the transition of the changing of the A/C servicing techniques.
