The NK-16 sample cooler provides a closed, cooled sampling path for checking boiler-water conductivity. Cooling the sample avoids the loss of water as flash steam that would otherwise affect an open-container sample.

Body: 3-inch AISI 304 stainless steel, PN16. Coil: AISI 316L stainless steel, 1/2-inch threaded, PN40. Sample inlet valve: 1/4-inch BSP stainless steel; catalogue valve limits 100 bar and 350 °C. Cooling-water inlet: 1/2-inch BSP. The catalogue lists cooling water at 10 bar and 100 °C; confirm the complete assembly rating against the required process conditions. Applications: steam boilers and steam generators.
