The Thermo Scientific NESLAB System I is a water-to-water heat exchanger engineered for laboratory and industrial applications demanding precise temperature control. It leverages existing facility water infrastructure to reject process heat, delivering a closed-loop cooling solution that eliminates contamination risk while reducing operational costs compared to compressor-based alternatives. The system maintains ±1°C temperature stability across a +5°C to +35°C operating range and delivers 14 kW (47,768 BTU) cooling capacity at +20°C.
