Multi-Stage Series Thermoelectric Coolers (TECs)

Coherent Thermal Solutions offers the multi-stage series thermoelectric coolers for high heat pumping applications

Image of Coherent Thermal Solutions' EverGen™ Mini-HarvestersCoherent Thermal Solutions' multi-stage thermoelectric coolers (TECs) are designed for medium to high heat pumping capacity requirements. Single-stage coolers can only obtain a ΔTmax of around +70°C.  Coherent Thermal Solutions builds multi-stage thermoelectrics with as many as five additional levels or "stages". Each additional stage allows for higher heat pumping capability and allows the thermoelectric to achieve a higher ΔT. The multistage cooler line offers superior cooling capabilities over single stage coolers while maintaining their solid-state benefits.

Features Applications
  • ROHS EU compliant
  • Higher heat pumping capability than single stage
  • Solid state reliability
  • Localized, spot cooling and precision temperature control
  • Operation in any orientation, zero gravity, and/or high G levels
  • High resistance to shock and/or vibration
  • No acoustical or electrical noise
  • High heat pumping applications within:
    • Automotive
    • Industrial
    • Telecommunications
    • Medical
    • Consumer
    • Aerospace and defense
    • Oil, gas, and mining
