The RRA 'sniffer' test has been accomplished when Marco Kramer, Director of Truetec B.V., could no longer guarantee the safety of his reefer engineers. This was a result of several alarming press reports in the 'reefer business', concerning several accidents caused by explosions while working on cool units. 

Immediately after taking notice of these reports, Truetec started their own investigation with a professional partner specialized in gas detection. After investigating the needs and necessities in the reefer industry RRA (Refrigerant Risk Assessment) was founded.

Detecting counterfeit refrigerants in a R134 filled system, whilst the safety of the performing reefer engineer is always the highest priority. The sampling takes place in a fully closed system, thus reducing the risk of accidents and/or exposal to a minor. 

In a system filled with R134a, the RRA sniffer test can detect several contaminants, for example CFK's like R12, R22 and R40.

​

This test can be performed in a quick and easy way that minimizes the odds of exposal and/or explosion of this contaminant. During this test the very dangerous R40 can be measured very clearly, even when it is mixed with other CFK's.

​

• The contamination with R40 is noticeable by a red colouring of our Refrigerant RIsk Assessment "Sniffer" Tube.

• Contamination with other CFK-mixes is noticable by a yellow colouring.

• No colouring will occur on non-contaminated systems.

Detecting these contaminations is very important to the safety of all people working with refrigeration systems; contaminated systems can explode spontaneously or leak lethal gasses, which increases the risk. Also severe contamination can have a serious effect on the lifespan of the refrigeration system. 

​

The RRA sniffer test is a tool to reduce safety risks in a quick, safe, cheap and on-field way, and also proceeding a perfect indication of the systems integrity. 

This test is already used by acknowledged companies in the refrigerating sector and Airconditioning systems. RRA is suitable for al coolings systems filled with refrigerants.
