Putting into Use Replacement Refrigerants (PURR) - 15 Sep 2015

This report has been produced by an Action Group made up of members of the British Refrigeration Association (BRA). The purpose of the report is to help people address the task of meeting some of the key implications and requirements of the EU F-Gas regulation which came into force on 1st January 2015.

The document is aimed at all stakeholders involved in the commercial refrigeration market – designers, manufacturers, installers, commissioners and end users – and is designed to highlight the challenges the sector faces in the next few years, and offer guidance and suggestions as to how these issues can be dealt with.

The ban on new installations and servicing with refrigerants with a Global Warming Potential of 2500 or more, together with the cap and phase down of HFC refrigerants, presents the sector with a major challenge. With a very tight timescale in which these factors must be actioned, the need for advice and information will be vital in the decision making process.

Sections 1 to 3 outline the challenge to be faced in more detail, and propose some of the actions that will need to be taken. Sections 4 and 5 contain detailed comments on replacement refrigerant candidates and the components that are relevant to their use. In Section 6, there is a summary of strategic matters that need addressing.

Code of Practice - Design and Manufacture of Refrigerated Cabinets running on Hydrocarbon Refrigerants - Version 2; March 2014

In order to support the increasing use of hydrocarbon refrigerants in integral commercial refrigerated cabinets the British Refrigeration Association Cabinet and Cold Store Section has commissioned this Code of Practice. It clarifies the regulations, standards and practices which apply to the leak simulation testing and subsequent design of systems which use hydrocarbon refrigerants. This will provide the basis for a consistent approach to be adopted by all manufacturers, end users and specifiers when using these refrigerants.

First published in January 2012, this March 2014 version has been updated to account for changes to standards and to include a statement on page 3 regarding the use of HC’s in systems above 150g which continues to cause concerns to some retailers in the UK.



Guide to flammable refrigerants - 25 October 2012

This guide has been prepared by the British Refrigeration Association (BRA) because of the increase in the application of flammable refrigerants such as hydrocarbons, HFOs and flammable HFCs.  It provides impartial information about the flammability issues associated with these refrigerants to end users, specifiers, building owners, manufacturers and contractors.  It is an introduction to flammable refrigerants and signposts where more detailed information can be obtained if necessary.

This guide applies to the use of flammable refrigerants in new, specially designed systems.  Existing systems using non-flammable refrigerants must not be retrofitted to flammable refrigerants.

Ammonia (R717) is not included in this Guide.  Section 10 shows where there is detailed information about R717.

Service of Hydrocarbon Refrigerant Equipment in a Retail Environment - 28 Feb 2012

In order to support the increasing use of hydrocarbon refrigerants in retail refrigeration and air conditioning equipment the British Refrigeration Association issued this Guidance. It summarises best practice for the service and maintenance of retail systems which use hydrocarbon refrigerants to ensure engineers work safely. Download

BRA Guide for Risk Assessments and Method Statements (RAMS) Issue 1 December 2011

The Method Statements give a brief description of the task that is to be assessed. The Risk Assessments describe the type of hazards that can occur, how to control them (and thereby reduce the associated risks) and what to do in the event of an accident or imminent danger occurring.
