REFTRADE carries out a RRA (Refrigerant Risk Assessment) on each refrigeration machinery. Counterfeit refrigerants should be detected in order to avoid negative effects on the refrigeration system and more important to avoid dangerous situations for the people working with it; contaminated systems can explode spontaneously or leak lethal gasses. In a system filled with R134, the RRA test can detect several contaminants like R12, R22 and R40. This test is being performed in a quick but careful way to minimize the odds of exposure and/or explosion of the contaminant. After being tested, the system is sealed. The supply of ‘clean’ refrigeration systems is of utmost importance to REFTRADE and fits perfectly in REFTRADE’s strive for perfection.
