The radiator contains a 1.06 m² (11.41 ft²) radiator element that acts as a heat exchanger to transfer thermal energy from water to air. The unit allows manual blower-speed control using either a built-in adjustment knob or external signals (0-5 V or 4-20 mA). The maximum air flow rate is 3060 L/min (106 ft³/min). The dual blower consists of two electric motors with fan blades that are powered by a 24 V dc, 2.4 A power supply output.
