II-VI Marlow's 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.  II-VI Marlow 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.
