• COMPACT HELICAL DESIGN WITH COUNTERFLOW FLUIDS FOR OPTIMUM HEAT TRANSFER
  
• FOUR MODELS DESIGNED TO RECOVER HEAT FROM 2 THROUGH 15 TON AIR CONDITIONING, REFRIGERATION, OR HEAT PUMP SYSTEMS
  
• DOUBLE-WALL INNER TUBE PROVIDES ISOLATION OF REFRIGERANT FROM WATER
  
• BOTH U.L. AND C.S.A. APPROVED FOR POTABLE WATER USE
  

The CDAX Series employs a "tube-in-tube" design: Potable water flows inside a double-wall convoluted copper tube in a counterflow direction to the refrigerant vapor flowing in the annulus between the convoluted tubing and the smooth outer steel tube, called the shell. This counterflow path provides the greatest temperature difference between the two fluids to yield optimum heat transfer.

The CDAX Series utilizes nested double-wall convoluted tubes having two leads: The double-wall isolates the refrigerant from the water to prevent contamination of the water in case of a leak in the convoluted tubing. The convolutions impart turbulence to both the water and the refrigerant flows, while offering all prime surface for maximum heat transfer area with minimum heat exchanger size.

Packless CDAX Series desuperheaters are constructed in a compact helical design. Four separate models are available for heat recovery from 2 thru 15 ton refrigerant R-22 systems.
