 MFG Part Number: 1515.01  
 Description: WL1500*  
The WL1500 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.

### Fluid Operating Points

Select Graph

 Qc vs ΔT (Ambient/Inlet) ΔT (Inlet/Outlet) vs Qc Pump Curve (Pressure vs Flow)

 ΔT min: 1.0 °C

 ΔT max: 17 °C

 **100% Water**  
 Cooling Power (Qc) = 1500 Watts  
 Thermal Conductance = 125.3 W/°C  
 ΔT (Ambient-Coolant)* = 12.0 °C  
 ΔT (Outlet-Inlet)** @ 6.0 L/min = 3.6 °C  

 **70/30 Water-Glycol**  
 Cooling Power (Qc) = 1500 Watts  
 Thermal Conductance = 112.0 W/°C  
 ΔT (Ambient-Coolant)* = 13.4 °C  
 ΔT (Outlet-Inlet)** @ 6.0 L/min = 3.8 °C  

 **60/40 Water-Glycol**  
 Cooling Power (Qc) = 1500 Watts  
 Thermal Conductance = 106.3 W/°C  
 ΔT (Ambient-Coolant)* = 14.1 °C  
 ΔT (Outlet-Inlet)** @ 6.0 L/min = 3.9 °C  

 **50/50 Water-Glycol**  
 Cooling Power (Qc) = 1500 Watts  
 Thermal Conductance = 103.3 W/°C  
 ΔT (Ambient-Coolant)* = 14.5 °C  
 ΔT (Outlet-Inlet)** @ 6.0 L/min = 4.1 °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.

### Notes

1. Check coolant level regularly. For optimal cooling performance, coolant level should always be above radiator fins.
2. Hose selection should be of material and thickness to support pressure resistance and coolant type.
3. Manual adjustments can be made to control pressure flow rate.
4. Check air filter and coolant filter periodically for replacement.
5. Multiple cord plug options available to accommodate regional socket outlet requirements. Consult with Laird Technologies on cord plug selection.
