The British Refrigeration Association (BRA) has published a Code of Practice for the design and manufacture of hydrocarbon refrigerated cabinets with a charge size greater than 150g, aiming to provide an impetus for a consistent approach adopted by manufacturers, end users and specifiers when using these refrigerants.
Against the backdrop of an increasing use of hydrocarbon refrigerants in integral commercial refrigerated cabinets, the Code aims to provide an impetus for a consistent approach to be adopted by manufacturers, end users and specifiers when using these refrigerants.
It clarifies the regulations, standards and practices that apply to the leak simulation testing and subsequent design of hydrocarbon refrigerated cabinets.
As a result, cabinets that are designed and manufactured in accordance with this Code meet basic safety principles with regard to the application of a flammable (class A3) refrigerant.
In scope: cabinets with hydrocarbon charge above 150g
Although also applicable to cabinets with less than 150g of hydrocarbon refrigerant charge, the Code is aimed at cabinets with a charge size greater than 150 g, including integral (plug in and hard‐wired) and close coupled remote type cabinets for food display, service and storage (stand alone and multiplexed).
The aspects covered by the Code
The Code covers the following aspects:
According to the new Code, a training module for professionals that is under development by the vocational awarding organisation City and Guilds should be available in early 2012.
About the British Refrigeration Association
The British Refrigeration Association (BRA) is a trade association representing manufacturers, importers, wholesalers, distributors, contractors, specifiers and end-users of refrigeration plant, equipment and components. It also includes producers of refrigerants and lubricants, colleges and training establishments. It works closely with government, public bodies and other organisations, both in the UK and overseas, to further the interests of the refrigeration industry.

The aspects covered by the Code
The Code covers the following aspects:
- Flammability: this section addresses charge size restrictions
- Introduction to the Design Process: reducing leak potential
- Simulated Leak Testing
- Electrical Devices – Types and Enclosures
- Air flow
- Labelling and Documentation
- Manufacture
- End User Post Installation Checks
- Service and Repair: personal leak detection, tools and equipment, procedures
- Training
According to the new Code, a training module for professionals that is under development by the vocational awarding organisation City and Guilds should be available in early 2012.
