F-Gas category I QQI
F-Gas category I QQI
Course Synopsis:
Level 5 QQI Special Purpose Certificate in F-gas Handling in Large RACHPT&T Systems Category I (10 Credits)
This course is aimed at candidates working in the commercial and Industrial refrigeration& Air conditioning sector.
This award is designed to meet the competence and training requirements of European Regulation (EC) No. 517/2014, Category I. The qualification is aimed at any individual seeking to work with F-gas in stationary refrigeration and Heating, Air Conditioning and Ventilation (HVAC) equipment, together with the refrigeration units of refrigerated trucks and trailers.
The programme has been developed to comply with current European Union (EU) and national regulations on the control and certification of people dealing with fluorinated greenhouse gases (F-gases), as specified by the current European Union (EU) and national regulations.
Typical Learner:
Our typical learner is a trade qualified technician dealing with refrigeration, HVAC and heat pumps. They will range from sole traders through to maintenance technicians working for multinational companies. This is a qualification designed for experienced workers, it is not entry level qualification.
Access to the programme is limited to learners currently undertaking Phase 2 of their apprenticeship in Refrigeration and Air Conditioning or who hold an advanced trades certificate in Refrigeration and Air Conditioning. Entry can also be achieved for those actively working in the commissioning and servicing of refrigeration, air-conditioning and heat pump systems who hold an advanced trades certificate, or equivalent academic qualification, together with documented relevant work experience in refrigeration and air conditioning. Such candidates must also complete an appropriate skill, knowledge, and language assessment, prior to commencing on the programme and complete a colour blindness test.
Theory classes can be provided in house or at a suitable location around Ireland. Practical classes will take place in our workshops in county Louth.
This course requires 100 learning hours split between Theory classes, Practical classes and self-directed learning.
