Technical Resources

A-Gas works with industry specialists and regulatory bodies to compile technical resources that assist practitioners in the HCAC&R industry.

The information contained within this website is for guidance only, for further system specific advice please call A‑Gas directly.

The AIRAH Technical handbook is the industry’s foremost technical reference, providing information on a vast array of material ranging from design data to minimum exhaust requirements, and everything in between. A range of Best Practice Guides and other technical resources are continually added to complement the DA Manuals and Technical Handbook.

  • A-Gas Refrig Health Check

    The A-Gas Refrig Health Check is designed to allow system owners to test the working fluids of a running system to establish whether the fluids are contaminated; the analysis results are accompanied by expert advice for remediation of any problems.

  • The Full Refrigerant Analysis Kit

    As a system owner, refrigeration equipment represents an expensive asset from a capital cost perspective. The Full Refrigerant Analysis kit is designed to provide laboratory analysis of contaminant levels in used refrigerant.

  • Trace-A-Gas Leak Detection Made Easy

    Trace-A-Gas is a non-flammable mixture of Nitrogen and Hydrogen designed for use in leak detection for HVAC&R systems. Hydrogen is an ideal leak detection medium due to its exceedingly small molecular size and low viscosity, this allows it to escape easily through any leak in greater volume than other gases aiding detection.

Flammable Refrigerants Safety Guide

AIRAH strongly recommends that all refrigeration technicians be trained in the handling of flammable refrigerants. Follow the link to access the information on the AIRAH website


The online Flammable Refrigerants Safety Guide (FRSG) has been produced by the Australian Institute of Refrigeration, Air Conditioning and Heating (AIRAH).

The free guide is designed to improve awareness of how to best manage the health and safety risks associated with the use and management of flammable refrigerants in stationary refrigeration and air conditioning equipment.

AIRAH would like to acknowledge support received from the Department of the Environment and Energy in developing this online training.
