MFG Part Number: 387002779.03
Description: WL3004
The WL3004 is a re-circulating liquid to air heat exchanger that offers dependable, compact performance by removing large amounts of heat from a liquid circuit. The coolant is re-circulated using a high pressure pump to assure maximum flow rate. Heat from coolant is absorbed by a radiant heat exchanger and dissipated into the ambient environment using brand name fan. Manual adjustments can be made to control flow switch. Customized features are available, however, MOQ applies.
- Cooling to ambient
- High heat pumping capacity
- Compact form factor
- Long life operation


Fluid Operating Points
Cooling Power (Qc) = 3000 Watts
Thermal Conductance = 248.8 W/°C
ΔT (Ambient-Coolant)* = 12.1 °C
ΔT (Outlet-Inlet)** @ 6.0 L/min = 7.2 °C
Cooling Power (Qc) = 3000 Watts
Thermal Conductance = 220.2 W/°C
ΔT (Ambient-Coolant)* = 13.6 °C
ΔT (Outlet-Inlet)** @ 6.0 L/min = 7.6 °C
Cooling Power (Qc) = 3000 Watts
Thermal Conductance = 206.0 W/°C
ΔT (Ambient-Coolant)* = 14.6 °C
ΔT (Outlet-Inlet)** @ 6.0 L/min = 7.9 °C
Cooling Power (Qc) = 3000 Watts
Thermal Conductance = 196.6 W/°C
ΔT (Ambient-Coolant)* = 15.3°C
ΔT (Outlet-Inlet)** @ 6.0 L/min = 8.3 °C
* ΔT (Ambient-Coolant) is the temperature difference between the ambient temperature and the coolant temperature that is at the outlet of the heat exchanger during steady-state operation. This temperature difference would initially be 0 and increase to the steady state value under load. This would also be the temperature at the inlet to the application.
** ΔT (Outlet-Inlet) is the temperature difference between the inlet temperature and the outlet temperature of the application at the nominal coolant flow. More flow (application pressure drop less than nominal) would necessarily mean a smaller ΔT.

- Check coolant level regularly. For optimal cooling performance, coolant level should always be above radiator fins.
- Hose selection should be of material and thickness to support pressure resistance and coolant type.
- Manual adjustments can be made to control pressure and flow rate.
- Check air and coolant filter periodically for replacement.
