Techtrain - Training Courses
Basic Refrigeration & Air Conditioning Course
Details
This is a five-day training course which can incorporate a City & Guilds 2078 assessment on the final day. The course can be held
for 4-8 candidates.
Each day is taken up by 50% theory and then 50% practical assignments.
The course can be held at our Training Centre in Doncaster or, with prior agreement, on-site at your premises.
Candidates will be issued with a full set of study notes and practical assignment folders at the start of the course.
Benefits
Techtrain Associates has written this course specifically for those who have little or no previous experience with refrigeration and air conditioning.
This course will benefit candidates who have some technical background in other disciplines or wish to cross train into refrigeration/air conditioning. It is also suitable for refrigeration engineers who wish to re-affirm their skills and knowledge within a fast changing technical environment and learn best practices of the Industry.
Parts of the course can be minimised or maximised to suit your particular company.
The content of the course is adjustable to cater for candidate specific equipment.
