Pure steam generator K / KS Series

In pharmaceutical and biotech manufacturing, steam purity is not an option. The K / KS Series delivers it across seven sizes from 5 to 60 kW, at 135 °C and 3.5 bar absolute, with process-contact parts in AISI 316L at Ra < 0.5 µm, traced orbital welds and Tri-Clamp ASME BPE connections with no dead legs. Two ways to drive it: the K-Series inside the bioreactor’s Bioflex™ software, the KS-Series on its own, with a 10" touchscreen. All cart-mounted, wherever the steam is needed.

K5 → K60 · 5 – 60 kWPure steam at 135 °CK-Series integrated · KS-Series stand-alone
