Maximum Heat Transfer With Minimal Pressure Drop

Turbo-DX is a seamless, internally enhanced tube with 60 or 75 ridges. It is designed primarily for direct expansion shell-and-tube liquid coolers. Refrigerant evaporating on the inside tube surface absorbs heat from water circulation on the outside of the tubes. Turbo-DX has been optimized to give maximum heat transfer performance with minimum refrigerant-side pressure drop for all the commonly used refrigerants. The inside heat transfer coefficient of the Turbo-DX is typically 1.5 to 3 times the coefficient for smooth surface tube.

The compact ridge design of Turbo-DX is fully compatible with rolling-in of the product into heat exchanger tube sheets. This feature makes tube plain ends unnecessary and permits the use of Turbo-DX cut from level wound coils. Turbo-DX is 100% tested to insure full conformance with North American and European pressure vessel standards. It is available in OD sizes (mm) of 9.52, 12.70, and 15.9, to facilitate a wide range of heat exchanger designs.

Turbo-DX Performance








Note: All performance data were obtained with oil-free refrigerant.

G	Tube-side fluid mass flux (kg/s-m²) = m/A_c,n	L	Tube length
h_i	Average tube-side heat transfer coefficient (kW/m^{2 × ^o}K)	X_in	Inlet refrigerant quality
