City & Guilds 6187-31 Level 3 Ammonia Qualification - Service and Maintenance


A recent addition to the new QCF qualifications introduced by City & Guilds, the 6187-31 provides a level 3 CPD pathway to developing an in depth knowledge of ammonia which goes beyond the basic refrigerant handling skills available in the 2078-02 award. Delegates can follow either a Service and Maintenance or an Installation and Commissioning route.

This course is only suitable for experienced engineers who have regular access to ammonia plant.


To achieve the City and Guilds 6187-31 Ammonia Level 3 qualification following either the Installation and Commissioning or Service and Maintenance route.


For either City and Guilds 6187-31 Ammonia Service and Maintenance or City and Guilds 6187-31 Ammonia Installation and Commissioning the learning structure will be tailored to group requirements but will include:

• 2 - 3 weeks actual 'contact' time during which a range of tuition will be given including power point presentations, practical work, assignments and the development of a portfolio. Access to ammonia plant will be required for part of this time.

• Self study time - an agreed time period between training sessions to allow evidence to be gathered and study to be completed.


Ammonia Level 3 Certificate in Refrigeration Systems Service and Maintenance

Two modules are completed for this qualification:

• Unit 320
Understand Ammonia Refrigeration Systems Service and Maintenance Techniques - 10 credits
Assessed by means of an externally set, internally marked, multiple choice question paper.

• Unit 324
Service and Maintain Refrigeration Systems - 3 credits
Assessed by means of a portfolio

The course will include the following topics:

• The working principles and layouts of ammonia refrigeration systems, equipment and components
• The operating principles and characteristics of the controls used
• The design principles which apply for the arrangement of ammonia refrigeration systems
• Legislative and organisational procedures for the servicing and maintenance of ammonia refrigeration systems
• Planning, preparing and carrying out servicing and maintenance of ammonia refrigeration systems
• Identifying and rectifying faults on ammonia refrigeration systems
• Understand procedures for the completion of pre-commissioning, commissioning, and decommissioning of ammonia refrigeration systems
• Be able to hand over ammonia refrigeration systems

Delegates must already hold their City & Guilds 2078-02 Ammonia Refrigerant Handling qualification although this can sometimes be taken during the course.

This course is always held on site and as well as access to an ammonia plant a classroom or equivalent will be needed for the presentations and paperwork.
