Hydro's new aluminium internal heat exchanger system can be used in a variety of air-conditioning applications with the present design being specifically optimized for the use in R744 (CO2) Mobile Air Conditioning. The "CO2AX" features a low weight of below 240 gramme/metre, a compact design of only 16 mm outer diameter, and a narrow bending radius of less than 15 mm. Moreover, it ensures a safe and efficient operation of any R744 A/C system due to its high burst pressure and a low pressure drop.
The cost-optimized co-axial product is the result of extensive Computational Fluid Dynamics (CFD) and Finite Element Methods (FEM) modelling work. It is available in several designs and alloy combinations to meet all market demands. In addition, Hydro's internal heat exchanger offers good forming and machining features and can also be delivered in different designs and cross sections upon request.
