MFG Part Number 387004692
UltraTEC™ UTX Series Thermoelectric Cooler
The UTX15-288-F2-5252-TA-W6 is a high-performance thermoelectric cooler that is assembled with advanced thermoelectric materials and can boost cooling capacity by up to 10%. The UltraTEC UTX Series features a higher thermal insulating barrier when compared to standard materials creating a maximum temperature differential (ΔT) of 71.7 °C at Qc = 0. It has a maximum Qc of 298.9 Watts when ΔT = 0.
  • High heat pump density
  • Precise temperature control
  • Reliable solid-state operation
  • No sound or vibration
  • DC operation
  • RoHS-compliant
