The recommended replacement is: MFG Part Number: 387009381.02 Description: LA5000* The LA5000 is a recirculating 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. ![Product image](/thermal-wizard/images/lcs/LA5000/LA5000-large.png) ### Features - Cooling to ambient - High heat pumping capacity - Compact form factor - Long life operation ### Applications - [Heat Exchangers For Today's Immersion Cooling Systems](/thermal-technical-library/application-notes/heat-exchangers-for-todays-immersion-cooling-systems) - [Cooling Particle Accelerators: Linear Accelerators and Cyclotrons](/resources/white-papers/cooling-particle-accelerators-linear-accelerators-and-cyclotrons) - [Semiconductor Fabrication Equipment Cooling](/applications/semiconductor-fabrication-equipment-cooling) - [X-ray Cooling in Industrial Scanners](/resources/application-notes/x-ray-cooling-industrial-scanners) ![Isometric drawing](/thermal-wizard/images/lcs/LA5000/LA5000-isometric-drawing.png) ### Technical Specifications **Performance** Nominal Cooling Capacity 5,000 W Nominal Operating Flowrate (60 Hz) 8.3 L/min @ 6.0 Bar Nominal Operating Flowrate (50 Hz) 7.5 L/min @ 6.0 Bar **Operation** Coolant Water or Water/Glycol Operating Temperature 5°C to 40°C Storage temperature range (w/o coolant) -25°C to 70°C Humidity range 20% to 80% Storage Humidity range 5% to 95%, non-condensing Input Voltage 230 VAC Frequency 50/60 Hz Current < 3.3 Amps Flow Switch Open ≤ 4 L/min Maximum Forward Pressure 10 Bar Compliance ANSI / UL / CSA / IEC EN 61010-1 Edition 3 **Physical** Height 529 mm Length 565 mm Width 468 mm Weight 40 kg Coolant Capacity 6.2 Liters Couplings 3/8 in NPT Features Applications Cooling to ambient Cooling Particle Accelerators: Linear Accelerators and Cyclotrons High heat pumping capacity Semiconductor Fabrication Equipment Cooling Compact form factor X-ray Cooling in Industrial Scanners Long life operation ### Fluid Operating Points Select Graph Qc vs ΔT (Ambient/Inlet) ΔT (Inlet/Outlet) vs Qc Pump Curve (Pressure vs Flow) ΔT min: 0.5 °C ΔT max: 16 °C **100% Water** Cooling Power (Qc) = 5000 Watts Thermal Conductance = 474.5 W/°C ΔT (Ambient-Coolant)* = 10.5 °C ΔT (Outlet-Inlet)** @ 8.3 L/min = 9.6 °C **70/30 Water-Glycol** Cooling Power (Qc) = 5000 Watts Thermal Conductance = 441.5 W/°C ΔT (Ambient-Coolant)* = 11.3 °C ΔT (Outlet-Inlet)** @ 8.3 L/min = 10.1 °C **60/40 Water-Glycol** Cooling Power (Qc) = 5000 Watts Thermal Conductance = 400.4 W/°C ΔT (Ambient-Coolant)* = 12.5 °C ΔT (Outlet-Inlet)** @ 8.3 L/min = 10.5 °C **50/50 Water-Glycol** Cooling Power (Qc) = 5000 Watts Thermal Conductance = 388.4 W/°C ΔT (Ambient-Coolant)* = 12.9 °C ΔT (Outlet-Inlet)** @ 8.3 L/min = 11.1 °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 and flow rate. 4. Check pump filter and dust on heat exchanger periodically for cleaning.
