2 F EATURES AND B ENEFITS OF L IEBERT D RYCOOLERS Heat Rejection Module The low-profile direct-drive propeller-fan type drycoolers utilize optimum circuitry to balance the heat rejec- tion of the corresponding load. Constructed of aluminum with a copper-tube aluminum coil, the unit is quiet and corr...
