Compressors and Expanders

Course Overview

The course includes an induction session to welcome and orientate the candidate, and familiarize them with the training centre, health and safety requirements and other important policies and procedures. The training consists of a mix of classroom and workshop sessions and various assessments. Upon successful completion, the candidates will gain the knowledge and understanding that will go towards enhancing their existing skills to plan and carry out the basic maintenance tasks on compressors and expanders.

The course is designed for an apprentice or beginner who would like to work as a Mechanical Technician or Maintenance Technician.

The candidate should have basic knowledge and skills in mechanical engineering.

Upon completing the training course, candidates will be awarded a ‘Certificate of Attendance’ from NTI, attested by the Ministry of Manpower.
