MFG Part Number 387006703 # SDAX-220-24-02 ## SuperCool X Series Thermoelectric Cooler Assembly The SDAX-220-24-02 Direct-to-Air thermoelectric cooler assembly is a high performance thermoelectric based heat pump. It is designed to temperature control small chambers used in medical diagnostics or sample storage compartments in analytical instrumentation. This unique, **patented** design offers a high performance hot side heat dissipation mechanism that convects heat more efficiently than conventional heat exchanger technologies. The design utilizes custom next-generation high-performance thermoelectric modules to maximize cooling capacity and premium grade fans to reduce noise. Moisture resistant insulation is used to keep condensation from penetrating into the thermoelectric module cavity. This unit operates at 24 VDC and is designed for indoor lab use environment. It has a maximum Qc of 220 Watts when ΔT = 0 and a maximum ΔT of 41 °C at Qc = 0. **Pending U.S. Patent Publication No. US2020/0240717** **Granted Patents:** - China: ZL2016800175855 - Japan: 6549721 - Switzerland: 3262909 - Germany: 6020160449986 - United Kingdom: 3262909 ![Product image](/thermal-wizard/images/tea/SuperCool%20X%20Series/SDAX-220-24-02/SDAX-220-24-02-large.png) ### Features - High performance - Compact form factor - Reliable solid-state operation - RoHS-compliant ### Applications - [Liquid Cooling Options for PET and SPECT Scanners](/resources/application-notes/liquid-cooling-options-pet-and-spect-scanners) - [Peltier Cooling for Refrigerated Centrifuges](/resources/application-notes/peltier-cooling-for-refrigerated-centrifuges) - [Heating and Cooling of Incubator Chambers](/resources/application-notes/heating-and-cooling-incubator-chambers) - [Thermal Management Solutions for Beverage Cooling](/resources/application-notes/thermal-management-solutions-beverage-cooling) ![Isometric drawing](/thermal-wizard/images/tea/SuperCool%20X%20Series/SDAX-220-24-02/SDAX-220-24-02-isometric-drawing.png) ![](/thermal-wizard/images/tea/CE-ROHS.png) ### Specifications Heat Transfer Mechanism, Cold Side Direct - Conduction Heat Transfer Mechanism, Hot Side Air - Forced Convection Operating Temperature Range -20°C to 60°C Supply Voltage 24.0 VDC nominal / 28.0 VDC maximum Current Draw 7.8 A running / 10.4 A startup Power Supply 207.0 Watts Performance Tolerance 10% Hi-Pot Testing 750 VDC Fan MTBF 60000 hours Sound Level (1 m distance) 63 dBA Weight 4.10 kg Panel Mounting Flush Mount ### Mounting Hole Location ![Mounting Hole Location](/thermal-wizard/images/tea/SuperCool%20X%20Series/SDAX-220-24-02/SDAX-220-24-02-mounting.png) ### Wiring Schematic ![Wiring Schematic](/thermal-wizard/images/tea/SuperCool%20X%20Series/SDAX-220-24-02/SDAX-220-24-02-wiring-schematic.png) ### Electrical and Thermal Performance **Optimum COP** Cooling Power (Qc) = 51.60 Watts TEM Voltage = 11.83 Volts TEM Current = 3.61 Amps TEM COP = 1.21 Power Supply = 54.7 Watts Power Dissipated (Qh) = 106.3 Watts Fan Voltage = 24.0 Volts Fan Current = 2.6 Amps **Maximum Qc** Cooling Power (Qc) = 156.67 Watts TEM Voltage = 28.11 Volts TEM Current = 9.19 Amps TEM COP = 0.61 Power Supply = 270.4 Watts Power Dissipated (Qh) = 427.1 Watts Fan Voltage = 24.0 Volts Fan Current = 2.6 Amps #### Default Calculated Operating Conditions ##### Electrical Operating Point - TEC Voltage: 24 V - TEC Current: 7.83 A - Cooling Power (Qc): 138.99 W - Power Supply: 199.91 W - TEC COP: 0.74 - Power Dissipated (Qh): 338.9 W - Fan Voltage: 24 V - Fan Current: 2.6 A ##### Thermal Operating Conditions Mode: Cooling - Ambient High Temperature: 35 °C - Control Temperature: 20 °C - Cooling ΔT: 15 °C ### Notes 1 For indoor use only 2 Units are generally maintenance free, however occasionally it is recommended to clean the heat sinks and fans of debris. This is best done with compressed air.
