F GAS ALERT

Here's a reminder that everyone handling the fluorinated refrigerants must hold the new City and Guilds or Constructionskills 'F Gas' qualification by 4th July this year.

These courses are filling up fast so if you haven't reserved a place already, call us NOW!

Which course?

For experienced engineers there is a choice of 3 short courses:

1 day, Assessment Only, at £250
2 day, Extra Theory and Assessment, at £365
3 day, Extra Practical, Theory and Asessment, at £555

All prices are per person and plus VAT.

These are only suitable for experienced engineers so if you're not sure that you have the knowledge or practical skills for this qualification, have a look at the check list below and be totally honest with yourself!

If you don't think you'd manage a short course, then we have a range of longer courses which can lead to an 'F Gas' refrigerant handling qualification as well as covering other topics:

5 day, Service and Maintenance with Refrigerant Handling,
at £910
5 day, Air Conditioning, Installation and Service, with Refrigerant Handling,
at £1160
10 day, Combined Service, maintenance and Installation with Copper Brazing and
Refrigerant Handling,
at £1875

As before, all prices are per person and plus VAT.

Full details of all our courses can be found elsewhere on the website. Availability is changing daily so we recommend that everyone contacts us for the latest information and to make a booking.

Checklist:
While not exhaustive this is a list of the main topics which will be covered to illustrate what knowledge and skills are required.

Theory - you will need to have an understanding of the following:

• Identify units of temperature, pressure, mass, density and enthalpy, including
different states of refrigerant
• Understand the basic theory of the vapour cycle and the use of pH diagrams
