At the SAE Symposium next week, Piflex® will present latest test results. The flexible all-aluminium tube solution for CO2 MAC has met and exceeded all test specifications by the German Association of the Automotive Industry.

After years of development and testing, the all-aluminium tube Piflex® is ready for serial application. Being tested in severe conditions to simulate the predicted lifetime for R744 MAC systems, the flexible line solution thus met and exceeded the most recent test requirements set down by the German Automotive Association (VDA). Tthe Piflex® flexible line solution between the compressor and gas cooler in all- aluminium also reduces energy needed for recycling. Overall, the permeation tight tubes absorb large movements showing high reliability in high-pressure, high-temperature CO2 air conditioning systems.

Test Results

Some of the key results to be fully presented at the SAE Symposium in Arizona are as follows:
