The Soeteck SY-CDU-RK-50 In-Rack Coolant Distribution Unit is a 50 kW pump-and-heat-exchange module that brings the secondary liquid loop inside the 19-inch cabinet itself. Its 450 x 850 x 175 mm chassis takes up only a narrow band of vertical rack space, so direct-to-chip cooling can go into an existing server row instead of waiting for a purpose-built plant room. Rated at 0.8 kW of pump power, the unit moves 4.56 m³/h on the secondary side at 50/40 °C, against 35/45 °C
