Product overviewThe Semistat S 4400 is a thermoelectric point-of-use temperature control unit designed for process applications requiring fast and precise temperature regulation. Its compact footprint and option for underfloor installation at the point of use reduce cleanroom occupied space. Precise control to ±0.1 K improves wafer-to-wafer homogeneity while delivering significant energy savings compared with compressor-based systems.
